You're one person doing the work of five. These three agents won't replace the other four, but they'll get you closer than anything else.
Agent 1: Cursor (for building) If you write any code at all — even if you're not a "developer" — Cursor is the single biggest productivity unlock available right now. It understands your entire codebase, suggests changes across multiple files, and has an agent mode that can autonomously implement features.
Why it's in this stack: As a solo founder, you can't afford to spend 3 days on something that should take 3 hours. Cursor compresses that.
Agent 2: Perplexity (for research) Every decision you make needs information. Competitor pricing, market size, technical feasibility, legal requirements. Perplexity replaces 80% of your Google searches with sourced, synthesized answers.
Why it's in this stack: Solo founders make hundreds of small decisions a week. Getting answers in 30 seconds instead of 30 minutes compounds fast.
Agent 3: Bolt.new (for prototyping) When you need to validate an idea, you need a working prototype — not a slide deck. Bolt.new turns a description into a working web app in minutes. It's not production-ready, but it's "show this to 10 potential customers and see if they care" ready.
Why it's in this stack: The #1 mistake solo founders make is building before validating. Bolt.new makes validation nearly free.
How they work together:
- Research your idea with Perplexity
- Prototype it with Bolt.new
- Get feedback, then build the real thing with Cursor
Total cost: ~$40-60/month for all three. That's less than one hour of freelance developer time.
