How to Choose a Software Development Company as a Startup

Picking the company that builds your product is one of the most expensive decisions you will make in your first year, and most founders make it after three sales calls and a gut feeling.

I build first versions of products for founders, and I also review other companies' quotes for founders before they sign. Most of what goes wrong has little to do with technology. It comes down to who does the work, what you can see along the way, and what you own at the end.

There is also a newer problem. AI tools changed how fast software gets built: by Google's 2025 DORA research, about 90% of software professionals now use them at work. A quote or timeline that looked normal a few years ago can be badly out of date today.

You do not need to be technical to judge any of this. Here is how to do it.

First, decide what kind of partner you need

"Software development company" covers very different setups. Pick the type before you compare companies, or you will end up comparing a solo freelancer's quote with an agency's and wondering why one is five times the other.

Eight questions to ask before you sign

Ask every company the same questions, ideally in writing so you can compare the answers side by side.

1. 1. Who exactly will build my product?

   The senior person on the sales call is often not the person who writes your code. You want to know who will, before you sign.

   Good answer

   Names and roles of the actual people on your project, and a chance to talk to them.

   Red flag

   Vague answers like "our team" or "we will assign the best people available".

2. 2. How do you use AI, and who checks its work?

   Almost every developer uses AI tools now. Used well, they make your product faster and cheaper to build. Used carelessly, they produce code that nobody has properly read, and the problems show up after launch.

   Good answer

   They use AI to move faster, and an experienced person reviews and tests every change before it reaches your users.

   Red flag

   No AI at all, so you pay for pre-AI timelines. Or AI writes everything and nobody can explain how it works.

3. 3. Can I see something you built that people still use?

   Screenshots and design mockups are easy to fake or borrow. A live product that real customers use is much harder to fake.

   Good answer

   A link you can click through today, and a past client you can call.

   Red flag

   Only a portfolio of images, or every past project is "under NDA" with nothing to show at all.

4. 4. What would you cut from my plan?

   A good partner wants you to launch early and learn from real users. A partner who agrees to everything is either padding the invoice or not thinking about your business.

   Good answer

   Specific suggestions, like launching with email login only and adding Google login later.

   Red flag

   "Yes, we can build all of that."

5. 5. How will I see progress?

   If the first time you see your product is at the end, every misunderstanding gets discovered when it is most expensive to fix.

   Good answer

   A working version you can click through yourself every one or two weeks.

   Red flag

   Status reports and percentages, with nothing to try until launch.

6. 6. Who owns the code and the accounts?

   If the company holds your code, servers, or app store listing, they hold your business. Switching partners later becomes slow and expensive.

   Good answer

   The code lives in your company's own account (usually GitHub) from day one, and hosting, domain, and app store accounts are in your name.

   Red flag

   "We will hand everything over at the end of the project."

7. 7. How do you price, and what happens when plans change?

   Plans always change once you see the product. You need to know what a change costs before it happens.

   Good answer

   A clear model, either a fixed price for a written scope or an hourly rate with a weekly report of hours, plus a simple process for approving changes.

   Red flag

   A fixed price for a vague scope. Every change then becomes a negotiation.

8. 8. What happens after launch?

   Bugs show up when real users arrive. And at some point you may want another developer to take over.

   Good answer

   A period of bug fixes included in the price, and written notes that let another developer continue the work.

   Red flag

   Silence, or support only through a new contract you have not seen yet.

Red flags in a proposal

Once the quotes arrive, read them for these warning signs. Any one of them is worth a direct question. Two or more and I would keep looking.

• They sent a price without asking anything about your users or your business.
• Each feature is one line with no detail, but the price is fixed.
• They cannot explain why they chose their technology in words you understand.
• Most of the money is due upfront instead of being tied to finished milestones.
• Testing, launch, and what happens after launch are not mentioned at all.
• The timeline runs to many months for a simple first version. With today's AI tools, ask what all that time is for.
• The product is built on their own private platform or framework, so only they can ever work on it.

How to compare quotes fairly

A simple scorecard

Score each company from 1 to 5 on every line after your calls. Ownership and progress matter more than the rest: a low score on either is a no, whatever the price.

When to get a second opinion

My rule of thumb: if you are about to sign for more than a few thousand dollars and nobody on your side can judge the proposal technically, have someone independent read it first. It costs a small fraction of the project, and the problems above are much cheaper to fix before you sign than after.

That is one of the things my $150 Strategy Session is for: you send me the proposals, we go through them together for 90 minutes, and you get a written recommendation within 48 hours.
