Best AI Tools for Startup Founders (2025)
Claude Pro ($20/month) — Most Versatile Founder Tool
Founders wear many hats. Claude handles the writing and thinking across all of them:
- Investor pitch decks: structure and draft compelling narratives
- Business plans: generate comprehensive frameworks to customize
- Product specs: translate founder vision into engineering requirements
- Fundraising materials: investor updates, one-pagers, due diligence responses
- Marketing copy: website copy, launch emails, press releases
- Legal documents: first drafts of NDAs, advisor agreements (always have lawyers review)
Cursor ($20/month) — Best for Technical Founders
For founders who code, Cursor dramatically accelerates product development. The ability to describe features in plain language and have Cursor implement them across multiple files is transformative for solo technical founders or small technical teams.
Perplexity ($20/month) — Best for Market Research
Rapid competitive intelligence, market sizing research, customer discovery synthesis, and investor landscape research — all with cited sources you can include in your materials.
