Build vs. buy: choosing AI tools as a solo founder
Updated
When you’re a solo founder, AI changes the build-versus-buy question. Coding agents make it tempting to build everything yourself, because you can. Meanwhile, a new AI tool launches every day promising to solve the problem you have this week.
Both paths can quietly eat your most limited resource: focus. Here is the framework we use across iMelonArt’s companies.
Start with a third option: do neither
Before building or buying, ask whether the problem needs solving now. Many early tasks are better done by hand for a few weeks. Doing them manually tells you exactly what a tool would need to do, and sometimes shows you the task doesn’t matter.
Rule of thumb: automate a task after you’ve done it by hand enough times to write down the steps.
When to buy
Buy when the tool is not your product and the problem is solved and standard:
- email marketing, payments, accounting, scheduling;
- transcription, basic writing assistance, design tools;
- anything where your requirements look like everyone else’s.
Buying wins here because the vendor maintains it, fixes it and keeps it secure. Your time is better spent on what customers pay you for.
Watch for: per-seat or per-usage pricing that grows faster than your revenue, and tools that hold your data in a format you can’t export.
When to build
Build when the capability is part of your edge, or when no tool fits how you actually work:
- the workflow is specific to your business, and off-the-shelf tools force awkward workarounds;
- you’d need to chain three or four paid tools to get one result;
- the thing you’d build is close to, or part of, your product.
Our own Agent Studio started this way. We needed agents that understood our brands, our channels and our review rules. No tool did that, so building it was justified, and it eventually became a product.
Watch for: the maintenance you’re signing up for. Every tool you build is one you’ll keep fixing.
A quick scoring test
For any tool decision, score each question from 1 to 3:
- How core is it? (1 = admin, 3 = part of the product)
- How unusual are your needs? (1 = standard, 3 = unique)
- How often will you use it? (1 = monthly, 3 = daily)
- How expensive is the buy option at your scale? (1 = cheap, 3 = expensive)
4–6: buy, or keep doing it by hand. 7–9: buy now, revisit in six months. 10–12: build, and keep it small.
Avoiding the two classic traps
- Tool sprawl. Ten subscriptions that each save a little time can cost more in logins, bills and context switching than they save. Review your tools every quarter and cancel anything you haven’t used in a month.
- Building to procrastinate. Building internal tools feels productive, and coding agents make it feel fast. If it doesn’t move revenue, users or the product, it can probably wait.
The question underneath
Build versus buy is really a question about where you want to spend your attention. Buy the things that let you forget about them, build the few things that make you different, and do neither until you know which is which.
