Frequently asked questions

How does ToolMango pick the best ai tools for startups?

Every tool gets an editorial ROI Score from 0–100 based on cost, time saved per week, revenue potential, ease of use, usefulness, popularity, affiliate payout, and category demand. We rank the highest-scoring tools first. Scores are recomputed weekly.

Are these affiliate links?

Some are. ToolMango may earn a commission when you click through and purchase, at no extra cost to you. Affiliate revenue keeps the site free and independent — it never decides which tools rank. Tools we don't have an affiliate relationship with still appear in this ranking when they earn it.

What's the minimum AI stack for a 2-person startup?

Cursor or Claude Code (engineering), Notion AI (docs and PRDs), Zapier (operations glue), Beehiiv (newsletter / audience). That's $80/month all-in. Add Surfer SEO once you start producing content.

Should we build with AI or buy AI tools?

Buy until it's a wedge. Building AI features into your product is a moat; using AI tools internally is table stakes. Don't confuse the two.
