 Exhibit 10.5 

WAIVER AGREEMENT 
 This
WAIVER AGREEMENT (this “Agreement”), dated as of February ____, 2021, is made by and among Six4 Holdings, LLC, a Delaware limited liability company (the “Sponsor”), the other holders of SPAC Class B Common
Stock (as defined below) set forth on Schedule I hereto (the “Other Class B Holders”, and together with the Sponsor, collectively, the “Class B Holders”), NavSight
Holdings, Inc., a Delaware corporation (“SPAC”) and Spire Global, Inc (the “Company”). Sponsor, Company and the Other Class B Holders, and SPAC shall be referred to herein collectively as the
“Parties” and individually as a “Party”. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Business Combination Agreement (as defined below). Sponsor, the
Class B Holders, and the Company are collectively referred to herein as the “Parties” and individually as a “Party.” 

WHEREAS, SPAC, NavSight Merger Sub Inc., a Delaware corporation and wholly-owned subsidiary of SPAC (“Merger Sub”), the
Company and certain other parties propose to enter into that certain Business Combination Agreement, dated as of the date hereof (as amended, restated, supplemented, or otherwise modified from time to time, the “Business Combination
Agreement”), pursuant to which, among other things, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving as a wholly owned subsidiary of SPAC; 

WHEREAS, the Class B Holders own shares of Class B common stock of SPAC (the “SPAC Class B Common
Stock”); and 
 WHEREAS, the Business Combination Agreement contemplates that the Parties will enter into this Agreement
concurrently with the entry into the Business Combination Agreement, pursuant to which the Class B Holders are waiving any adjustment to the conversion ratio set forth in the Certificate of Incorporation or any other anti-dilution or similar
protection with respect to the shares of SPAC Class B Common Stock related to the transactions contemplated by the Business Combination Agreement, with the result that shares of SPAC Class B Common Stock will convert into shares of
Class A common stock of SPAC (“SPAC Class A Common Stock”) on a 1-for-1 basis, subject to, and conditioned upon, the occurrence
of the Closing and effective as of immediately prior to the Merger. 
 NOW, THEREFORE, in consideration of the premises and the mutual
promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, each intending to be legally bound, hereby agree as follows: 

1. Waiver of Anti-Dilution Protection. Subject to, and conditioned upon, the occurrence of the Closing, each of the Class B
Holders, by this Agreement, hereby irrevocably waives (for such Class B Holder and for such Class B Holder’s successors, heirs and assigns), to the fullest extent of the law and the Certificate of Incorporation, and agrees not to
assert or perfect, any rights to adjustment or other anti-dilution protections with respect to the rate at which the shares of SPAC Class B Common Stock held by such Class B Holder as of the date hereof or as of immediately prior to the
consummation of the Business Combination Agreement convert into shares of SPAC Class A Common Stock in connection with the transactions contemplated by the Business Combination Agreement; provided that, for the avoidance of doubt, the
shares of SPAC Class B Common Stock held by each such Class B Holder as of immediately prior to the consummation of the Business Combination Agreement shall convert to shares of SPAC Class A Common Stock on a 1-for-1 basis upon the consummation of the transactions contemplated by the Business Combination Agreement (subject to adjustment for any share split, reverse share split or
similar equity restructuring transaction involving SPAC). 












 2. Termination. This Agreement shall terminate and shall be of no further force and
effect if, and at such time, if any, as, the Business Combination Agreement is terminated in accordance with its terms prior to the Closing. 

3. Waiver. Any Party may, at any time prior to the Closing, by action taken by its board of directors or equivalent governing body, or
officers thereunto duly authorized, waive in writing any rights or conditions in its favor under this Agreement or agree to an amendment or modification to this Agreement in the manner contemplated by Section 10 and by an agreement in writing
executed in the same manner (but not necessarily by the same Persons) as this Agreement. 
 4. Notices. All notices and other
communications among the Parties shall be in writing and shall be deemed to have been duly given (i) when delivered in person, (ii) when delivered after posting in the United States mail having been sent registered or certified mail return

remedy, would occur in the event that the Parties do not perform their obligations under the provisions of this Agreement (including failing to take such actions as are required of them hereunder to consummate this Agreement) or any Transaction
Agreement in accordance with its specified terms or otherwise breach such provisions. The Parties acknowledge and agree that (a) the Parties shall be entitled to an injunction, specific performance, or other equitable relief, to prevent
breaches of this Agreement and to enforce specifically the terms and provisions hereof and thereof, without proof of damages, prior to the valid termination of this Agreement in accordance with Section 2, this being in addition to any other
remedy to which they are entitled under this Agreement, and (b) the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without that right, none of the Parties would have entered into this
Agreement. Each Party agrees that it will not oppose the granting of specific performance and other equitable relief on the basis that the other Parties an adequate remedy at Law or that an award of specific performance is not an appropriate remedy
for any reason at Law or equity. The Parties acknowledge and agree that any Party seeking an injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this
Section 13 shall not be required to provide any bond or other security in connection with any such injunction.
