 Exhibit 10.2 

INVESTMENT MANAGEMENT TRUST AGREEMENT 

This Investment Management Trust Agreement (this “Agreement”) is made effective as of March 16, 2021, by and
between Build Acquisition Corp., a Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Company, a New York limited purpose trust company (the “Trustee”). 

WHEREAS, the Company’s registration statement on Form S-1, File No. 333-253664 (the
“Registration Statement”), and prospectus (the “Prospectus”) for the initial public offering of the Company’s units (the “Units”), each of which consists of one share of
the Company’s Class A common stock, par value $0.0001 per share (“Common Stock”), and one-third of one redeemable warrant, each whole warrant entitling the holder thereof to
purchase one share of Common Stock (such initial public offering hereinafter referred to as the “Offering”), has been declared effective as of the date hereof by the U.S. Securities and Exchange Commission; and 

WHEREAS, the Company has entered into an Underwriting Agreement (the “Underwriting Agreement”) with Cowen and Company,
LLC and Allen & Company LLC, as the underwriters (the “Underwriters”); and 
 WHEREAS, as described in the
Prospectus, $200,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants (as defined in the Underwriting Agreement) (or $230,000,000 if the Underwriters’ over-allotment option is exercised in full) will be
delivered to the Trustee to be deposited and held in a segregated trust account located at all times in the United States (the “Trust Account”) for the benefit of the Company and the holders of the shares of Common Stock
included in the Units issued in the Offering as hereinafter provided (the amount to be delivered to the Trustee (and any interest subsequently earned thereon) is referred to herein as the “Property,” the stockholders for
whose benefit the Trustee shall hold the Property will be referred to as the “Public Stockholders,” and the Public Stockholders and the Company will be referred to together as the “Beneficiaries”); and

 WHEREAS, pursuant to the Underwriting Agreement, a portion of the Property equal to $7,000,000, or $8,050,000 if the Underwriters’
over-allotment option is exercised in full, is attributable to deferred underwriting discounts and commissions that may be payable by the Company to the Underwriters upon the consummation of the Business Combination (as defined below) (the
“Deferred Discount”); and 
 WHEREAS, the Company and the Trustee desire to enter into this Agreement to set forth
the terms and conditions pursuant to which the Trustee shall hold the Property. 
 NOW THEREFORE, IT IS AGREED: 

1.    Agreements and Covenants of Trustee. The Trustee hereby agrees and covenants to: 

(a)    Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust
Account established by the Trustee located in the United States at JPMorgan Chase Bank N.A. (or at another U.S. chartered commercial bank with consolidated assets of $100 billion or more) and at a brokerage institution selected by the Trustee
that is reasonably satisfactory to the Company; 
 (b)    Manage, supervise and administer the Trust Account subject to
the terms and conditions set forth herein; 
 (c)    In a timely manner, upon the written instruction of the Company,
invest and reinvest the Property in United States government securities within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 185 days or less, or in money market funds meeting the
conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated under the Investment Company Act of 1940, as amended (or any successor rule), which invest only in direct U.S. government
treasury obligations, as determined by the Company; the Trustee may not invest in any other securities or assets, it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s
instructions hereunder; while on deposit, the Trustee may earn bank credits or other consideration; 
 (d)    Collect
and receive, when due, all interest or other income arising from the Property, which shall become part of the “Property,” as such term is used herein; 

(e)    Promptly notify the Company and the Underwriters of all communications received by the Trustee with respect to any
Property requiring action by the Company; 

  
 1 













 (f)    Supply any necessary information or documents as may be requested
by the Company (or its authorized agents) in connection with the Company’s preparation of tax returns relating to assets held in the Trust Account or in connection with the preparation or completion of the audit of the Company’s financial
statements by the Company’s auditors; 
 (g)    Participate in any plan or proceeding for protecting or enforcing
any right or interest arising from the Property if, as and when instructed by the Company to do so; 
 (h)    Render to
the Company monthly written statements of the activities of, and amounts in, the Trust Account reflecting all receipts and disbursements of the Trust Account; 

(i)    Commence liquidation of the Trust Account only after and promptly following (x) receipt of, and only in
accordance with the terms of, a letter from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B, as applicable, signed on
behalf of the Company by its Co-Chief Executive Officer, Chief Financial Officer or other authorized officer of the Company (an “Authorized Representative”), and complete the
liquidation of the Trust Account and distribute the Property in the Trust Account, including interest (which interest shall be net of any taxes payable, and less up to $100,000 of interest that may be released to the Company to pay dissolution
expenses), only as directed in the Termination Letter and other documents referred to therein, or (y) upon the date which is the later of (1) 24 months after the closing of the Offering and (2) such later date as may be approved by
the Company’s stockholders in accordance with the Company’s amended and restated certificate of incorporation, as amended from time to time, if a Termination Letter has not been received by the Trustee prior to such date, in which case the
Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account, including interest (which interest shall be net of any taxes
payable, and less up to $100,000 of interest that may be released to the Company to pay dissolution expenses) shall be distributed to the Public Stockholders of record as of such date; 

(j)    Upon written request from the Company, which may be given from time to time in a form substantially similar to that
attached hereto as Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and distribute on behalf of the Company the amount of interest earned on the Property requested by the Company
to cover any tax obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt
payment, and the Company shall forward such payment to the relevant taxing authority; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate
such assets held in the Trust Account as shall be designated by the Company in writing to make such distribution so long as there is no reduction in the principal amount per share initially deposited in the Trust Account; provided,
further, however, that if the tax to be paid is a franchise tax, the written request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill for the Company and a written statement from
the principal financial officer of the Company setting forth the actual amount payable (it being acknowledged and agreed that any such amount in excess of interest income earned on the Property shall not be payable from the Trust Account). The
written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said request; 

(k)    Upon written request from the Company, which may be given from time to time in a form substantially similar to that
attached hereto as Exhibit D (a “Stockholder Redemption Withdrawal Instruction”), the Trustee shall distribute to or on behalf of the Company the amount requested by the Company to be used to redeem shares of
Common Stock from Public Stockholders properly submitted in connection with a stockholder vote to approve an amendment to the Company’s amended and restated certificate of incorporation (A) to modify the substance or timing of the
Company’s obligation to allow redemptions in connection with its initial Business Combination or to redeem 100% of the Company’s public shares of Common Stock if the Company does not complete its initial Business Combination within the
time period set forth therein or (B) with respect to any other provision relating to the Company’s stockholders’ rights or pre-initial Business Combination activity. The written request of the Company referenced above shall constitute
presumptive evidence that the Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request; and 

(l)     Not make any withdrawals or distributions from the Trust Account other than pursuant to Section 1(i),
(j) or (k) above.

 2.    Agreements and Covenants of the Company. The Company hereby
agrees and covenants to: 
 (a)    Give all instructions to the Trustee hereunder in writing, signed by an Authorized
Representative of the Company. In addition, except with respect to its duties under Sections 1(i), 1(j) and 1(k) hereof, the Trustee shall be entitled to rely on, and shall be protected in relying on, any
verbal or telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any one of the persons authorized above to give written instructions, provided that the Company shall promptly confirm such
instructions in writing; 
 (b)    Subject to Section 4 hereof, hold the Trustee harmless and
indemnify the Trustee from and against any and all reasonable and documented expenses, including reasonable outside counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder and in
connection with any action, suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or
the Property or any interest earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the
commencement of any action, suit or proceeding, pursuant to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company in writing of such claim (hereinafter referred to as the
“Indemnified Claim”). The Trustee shall have the right to conduct and manage the defense against such Indemnified Claim; provided that the Trustee shall obtain the consent of the Company with respect to the selection of
counsel, which consent shall not be unreasonably withheld. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company, which such consent shall not be unreasonably withheld. The Company may participate
in such action with its own counsel; 
 (c)    Pay the Trustee the fees set forth on Schedule
A hereto, including an initial acceptance fee, annual administration fee, and transaction processing fee, which fees shall be subject to modification by the parties from time to time. It is expressly understood that the Property
shall not be used to pay such fees unless and until it is distributed to the Company pursuant to Sections 1(i) through 1(j) hereof. The Company shall pay the Trustee the initial acceptance fee and the first
annual administration fee at the consummation of the Offering. The Company shall not be responsible for any other fees or charges of the Trustee except as set forth in this Section 2(c) and as may be provided in Section
2(b) hereof; 
 (d)    In connection with any vote of the Company’s stockholders regarding any
merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination involving the Company and one or more businesses (a “Business Combination”), provide to the Trustee an
affidavit or certificate of the inspector of elections for the stockholder meeting verifying the vote of such stockholders regarding such Business Combination; 

(e)    Provide the Underwriters with a copy of any Termination Letter(s) and/or any other correspondence that is sent to
the Trustee with respect to any proposed withdrawal from the Trust Account promptly after it issues the same; 

(f)    Expressly provide in any Instruction Letter (as defined in Exhibit A) delivered in connection with a
Termination Letter in the form of Exhibit A that the Deferred Discount be paid directly to the account or accounts directed by the Underwriters; and 

(g)    Instruct the Trustee to make only those distributions that are permitted under this Agreement, and refrain from
instructing the Trustee to make any distributions that are not permitted under this Agreement. 
 3.    Limitations
of Liability. The Trustee shall have no responsibility or liability to: 
 (a)    Imply obligations, perform duties,
inquire or otherwise be subject to the provisions of any agreement or document other than this Agreement and that which is expressly set forth herein; 

(b)    Take any action with respect to the Property, other than as directed in Section 1 hereof, and the
Trustee shall have no liability to any party except for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct; 

(c)    Institute any proceeding for the collection of any principal and income arising from, or institute, appear in or
defend any proceeding of any kind with respect to, any of the Property unless and until it shall have received instructions from the Company given as provided herein to do so and the Company shall have advanced or guaranteed to it funds sufficient
to pay any expenses incident thereto; 

  
 3 













 (d)    Refund any depreciation in principal of any Property; 

(e)    Assume that the authority of any person designated by the Company to give instructions hereunder shall not be
continuing unless provided otherwise in such designation, or unless the Company shall have delivered a written revocation of such authority to the Trustee; 

(f)    The other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to
be taken or omitted, in good faith and in the Trustee’s best judgment, except for the Trustee’s gross negligence, fraud or willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon any written direction,
order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Trustee with written notification to the Company, which counsel may be the Company’s counsel), statement, instrument, report or other paper or
document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained) which the Trustee believes, in good faith and with reasonable care, to
be genuine and to be signed or presented by the proper person or persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless evidenced
by a written instrument delivered to the Trustee, signed by the proper party or parties and, if the duties or rights of the Trustee are affected, unless it shall give its prior written consent thereto; 

(g)    Verify the accuracy of the information contained in the Registration Statement; 

(h)    Provide any assurance that any Business Combination entered into by the Company or any other action taken by the
Company is as contemplated by the Registration Statement; 
 (i)    File information returns with respect to the Trust
Account with any local, state or federal taxing authority or provide periodic written statements to the Company documenting the taxes payable by the Company, if any, relating to any interest income earned on the Property; 

(j)    Prepare, execute and file tax reports, income or other tax returns and pay any taxes with respect to any income
generated by, and activities relating to, the Trust Account, regardless of whether such tax is payable by the Trust Account or the Company, including, but not limited to, franchise and income tax obligations, except pursuant to Section
1(j) hereof; or 
 (k)    Verify calculations, qualify or otherwise approve the Company’s written requests
for distributions pursuant to Sections 1(i), 1(j) or 1(k) hereof. 
 4.    Trust
Account Waiver. The Trustee has no right of set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably
waives any Claim to, or to any monies in, the Trust Account that it may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including, without limitation, under Section
2(b) or Section 2(c) hereof, the Trustee shall pursue such Claim solely against the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust Account. 

5.    Termination. This Agreement shall terminate as follows: 

(a)    If the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company
shall use its reasonable efforts to locate a successor trustee, pending which the Trustee shall continue to act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor trustee has been appointed and has
agreed to become subject to the terms of this Agreement (whether following the Trustee giving notice that it desires to resign under this Agreement or the Company otherwise electing to replace the Trustee under this Agreement), the Trustee shall
transfer the management of the Trust Account to the successor trustee, including but not limited to the transfer of copies of the reports and statements relating to the Trust Account, whereupon this Agreement shall terminate; provided,
however, that in the event that the Company does not locate a successor trustee within ninety (90) days of receipt of the resignation notice from the Trustee, the Trustee may submit an application to have the Property deposited with any
court in the State of New York or with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune from any liability whatsoever; 

(b)    At such time that the Trustee has completed the liquidation of the Trust Account and its obligations in accordance
with the provisions of Section 1(i) hereof and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate except with respect to Section 2(b); or 

  
 4 













 (c)    If the Offering is not consummated within ten (10) business
days of the date of this Agreement, in which case any funds received by the Trustee from the Company or Build Acquisition Sponsor LLC, as applicable, shall be returned promptly following the receipt by the Trustee of written instructions from the
Company. 
 6.    Miscellaneous. 

(a)    The Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth herein
with respect to funds transferred from the Trust Account. The Company and the Trustee will each restrict access to confidential information relating to such security procedures to authorized persons. Each party must notify the other party
immediately if it has reason to believe unauthorized persons may have obtained access to such confidential information, or of any change in its authorized personnel. In executing funds transfers, the Trustee shall rely upon all information supplied
to it by the Company, including, account names, account numbers, and all other identifying information relating to a Beneficiary, Beneficiary’s bank or intermediary bank. Except for any liability arising out of the Trustee’s gross
negligence, fraud or willful misconduct, the Trustee shall not be liable for any loss, liability or out-of-pocket expense resulting from any error in the information or
transmission of the funds. 
 (b)    This Agreement shall be governed by and construed and enforced in accordance with
the laws of the State of New York. 
 (c)    This Agreement contains the entire agreement and understanding of the
parties hereto with respect to the subject matter hereof. Except for Section 1(i), 1(j) or 1(k) (which sections may not be modified, amended or deleted without the affirmative vote of sixty-five percent (65%) of the
then outstanding shares of Common Stock and Class B common stock, par value $0.0001 per share, of the Company voting together as a single class; provided that no such amendment will affect any Public Stockholder who has otherwise validly
indicated his, her or its election to redeem his, her or its shares of Common Stock in connection with a stockholder vote sought to amend this Agreement), this Agreement or any provision hereof may only be changed, amended or modified (other than to
correct a typographical error) by a writing signed by each of the parties hereto. 
 (d)    The parties hereto consent
to the jurisdiction and venue of any state or federal court located in the City of New York, State of New York, for purposes of resolving any disputes hereunder. AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY RELATING TO THIS AGREEMENT,
EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY.

 Re:    Trust Account – Termination Letter 

Dear Mr. Wolf and Ms. Gonzalez: 

Pursuant to Section 1(i) of the Investment Management Trust Agreement between Build Acquisition Corp. (the
“Company”) and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of [●], 2021 (the “Trust Agreement”), this is to advise you that the Company
has entered into an agreement with [●] (the “Target Business”) to consummate a Business Combination on or about [●], 202[●]. The Company shall notify you at least
seventy-two (72) hours in advance of the actual date (or such shorter time period as you may agree) of the consummation of the Business Combination (the “Consummation Date”).
Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement. 
 In accordance with the terms of
the Trust Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account and to transfer the proceeds into the above-referenced trust operating account at JPMorgan Chase Bank, N.A. to the effect that, on the
Consummation Date, all of the funds held in the Trust Account will be immediately available for transfer to the account or accounts that the Underwriters (with respect to the Deferred Discount) and the Company shall direct on the Consummation Date.
It is acknowledged and agreed that while the funds are on deposit in the trust operating account at JPMorgan Chase Bank, N.A. awaiting distribution, neither the Company nor the Underwriters will earn any interest or dividends. 

On the Consummation Date (i) counsel for the Company shall deliver to you written notification that the Business Combination has been
consummated, or will be consummated substantially, concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”) and (ii) the Company shall deliver to you (a) a certificate
by a Co-Chief Executive Officer or Chief Financial Officer of the Company, which verifies that the Business Combination has been approved by a vote of the Company’s stockholders, if a vote is held, and
(b) joint written instruction signed by the Company and the Underwriters with respect to the transfer of the funds held in the Trust Account, including payment of the Deferred Discount from the Trust Account (the “Instruction
Letter”). You are hereby directed and authorized to transfer the funds held in the Trust Account immediately upon your receipt of the Notification and the Instruction Letter, in accordance with the terms of the Instruction Letter. In
the event that certain deposits held in the Trust Account may not be liquidated by the Consummation Date without penalty, you will notify the Company in writing of the same and the Company shall direct you as to whether such funds should remain in
the Trust Account and be distributed after the Consummation Date to the Company. Upon the distribution of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the Trust Account, your obligations
under the Trust Agreement shall be terminated. 
 In the event that the Business Combination is not consummated on the Consummation Date
described in the notice thereof and we have not notified you on or before the original Consummation Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from the Company, the funds held in the Trust Account shall
be reinvested as provided in Section 1(c) of the Trust Agreement on the business day immediately following the Consummation Date as set forth in the notice as soon thereafter as possible.
