What founders should NOT buy in 2026
Skip these unless you have a specific need:
- Enterprise tools (Devin at $500, Harvey at $$$$) — wait until you're past PMF
- LangChain/LangGraph framework — use vendor SDKs instead until complexity demands more
- Custom AI infrastructure — buy off-the-shelf at startup scale
- AI SDR tools (11x, Artisan) — premature until you have a real ICP
A common founder mistake
Buying too many AI tools. Three tools used daily beats ten tools used occasionally. Start minimum, expand only when you hit specific friction.
The verdict
- Pre-seed solo founder → Cursor + ChatGPT + Perplexity ($60/mo)
- Seed-stage with co-founder → Add Lindy + Manus ($150/mo)
- Post-PMF, hiring team → Add Decagon for support + Tavus for outreach
- Series A+ → Custom stack tuned to actual workflows
