Thanks for your effort on compiling this response for us, I appreciate it. I will try to answer your questions.

>>They have demand for their services

>How do you know? Do they have demand for their services or do their clients keep asking them for something similar to your product which they don't have which lead them to you in the first place?

They use something similar to our product, in this case Microsoft Power Apps, and in some cases for certain clients they want to use our solution as it is easy/fast and affordable to implement for their needs.

>>they want to sell our solutions, after polishing it

>What polishing exactly is there to make and who does the polishing? I bet that the first and probably the only polishing is to slap a big logo or "Provided by X" company and removing any sent of yours.

Mostly complete implementation of some unfinished features such as Connectors and Workflows and also general bug fixes.

>>They want to see the option where they would take care of these expenses, through a payroll from they're existing company.

>:D :D :D Obviously don't become their employee.

Sure, that was only a discussion between me and one of their founders and they mentioned it as alternative.

>>We however opened a company and want to keep it, but try to involve them in our company with some kind of equity structure or something

>Why are you even talking about equity here? If there' any conversation, it should be about you considering hiring them to sell your product, and comparing them to many other organizations who can do that for you. On commission, or something like that. Think of them as a sales organizations, or a recruiting agency and so far they haven't made any sales or provided you with any successful hire yet (job to be done). They claim to have many clients they can sell your product to, your reaction should be "Show me". Start with one sale and see where it goes.

The product is not yet on the final stage (Workflows, Connectors which will be needed for implementing use-cases for them). The idea was to be able to work on this full time, and to take some kind of investment from their side. I thought it as a form of pre-seed funding but separate it on chunks / pay every month.

>>they are interested in helping us with business development, bringing us clients, and the sales part, so we can focus mostly on implementation/tech parts

>Helping? OK, then tell them to bring you a client.

That would be the case if the product is in the final stage. Maybe my bad for not mentioning it in a more clear way on the original question.

>>They have tremendous experience in different industries

> How do you know? Did someone there tell you?

I had a long conversation with them and they told me about their experiences. I double checked that through Linkedin.

>>and experience working with big corporations

>The pitch started with them selling to smaller clients.

Thats correct that the pitch started with them selling to smaller clients. I meant to kind of tell more about their credibility , as that would benefit us in term of growing this into a more solid company.

>>Also, they have 50 people working for them and they are saying that they can share some of their resources with us.

> To do what, exactly?

Mostly business development, that would be their personal time (the owners). They have lot of people that use existing similar tools and we can benefit on terms of product development as well. But we need to clear this up in a more details.

I agree with other points and will consider them if we come to an agreement, and make sure to outline them in writing also.

> Do you have clients and are you generating revenue? Have you already made a few sales?

We have one client already using our finished parts of the platform. They're paying us $250 monthly.
