You are the whole team. These tools are the roles you cannot hire yet.

Run the Stack Grader. It replaces a $3k to $15k fractional-CTO MVP audit in 3 minutes and gives you a prioritized fix plan so you know what to do next Tuesday, not just what is broken.

For pre-launch to first-real-users it is enough on its own. If you sell into regulated industries (health, finance, defense) or into enterprise buyers with SOC 2 requirements, you will still need a real audit at some point. For every other solo founder heading toward public launch, this is a complete pre-launch kit.

Three levers, in order of impact. First, use the Cost Comparator to pick a cheap primary model plus a premium fallback for hard cases rather than defaulting to premium everywhere. Second, cache prompts and responses. Third, set per-user daily budget caps so one heavy user cannot burn your entire month. Cost Comparator suggests all three based on your usage.

Grade your stack (Stack Grader, 3 min), model your AI bill (Cost Comparator, 2 min), work the launch checklist for your stack (30 min to an hour of reading, then a week of doing). Then launch to a small circle. Then hit Product Hunt / Indie Hackers / your community.

Almost always: rate limits (or the lack thereof), OTP or payment webhooks getting abused, and error monitoring nobody looks at. All three are covered in the Stack Grader with specific fixes. Backups being untested is the second wave: it works fine until you need it, and if you have never run a restore you find out at the worst time.

No. There is no paid tier of Cafiyn Pulse. You get every category of every tool for free, no card, no trial expiring.

The Cost Comparator recommendation engine reads your usage sliders and names a routing strategy. The Stack Grader fix plan tells you what to do next. The Launch Checklist tells you what stack-specific step comes next. Not a co-founder, but it removes the "what should I do next" question at the three most expensive stages.
