2 · Build vs. buy vs. no-code

You almost never have to build AI from scratch. The founder's question isn't "how do I train a model?" — it's "what's the lightest way to deliver this with AI?" Picking the right approach can save you months and thousands of dollars.

Three honest paths, lightest to heaviest:

Buy / integrate an existing AI tool. Use a product that already does the AI part (a chat tool, an AI writing or transcription app, an AI feature inside software you already pay for). Fastest, cheapest to start, least control. Great when an off-the-shelf tool already does 80% of the job.
No-code / low-code with an AI step. Wire together tools you don't have to code: a form, an automation platform, a chatbot builder, with an AI step in the middle ("when a request comes in, summarize it and draft a reply"). You own the workflow without owning engineering. Ideal for an AI-assisted service or a first product.
Build with an API (or hire someone who can). Call a model's API from custom code for full control, your own data, and real guardrails. This is the Builder track's home turf (F2) — powerful, but it's real software with real maintenance. As a founder, reach for it only when the lighter paths stop fitting, and know you may need to hire that skill.

Decide with a few blunt questions:

Ask yourself	Lean toward
Does a tool already do most of this?	Buy / integrate
Is it "when X happens, do steps, one uses AI"?	No-code / low-code
Do I need custom logic, my own data, real control?	Build (API) — or hire it

The founder's discipline: start as light as the job allows. Over-engineering is its own kind of slop — and the heaviest path is also the most expensive to run and maintain. You can always move down the ladder later, once customers prove the idea is worth the heavier build.

Check yourself. For your idea, which path fits the first version — buy, no-code, or build — and what's the one fact about the job that decides it?
