I would ask the bait post that countless others have... "Has anyone actually let ai rewrite a real production codebase or is this all just vibes" but i actually have.

Is the growth hack still just post useful stuff or burn a billion tokens on a demo

this is usually a good but humbling exercise to validate your product/idea. if you have no distribution Work out the most u can pay for one customer before u spend anything Paste the prompt below with ur price and margin. It shows if can actually get u a paying user at that price

Price: [£/month] Margin: [%] Payback: [n] months Channel: meta or google Work out the most I can pay per paying user. Turn typical CPC for my category into cost per paying user with conservative conversion rates and show the maths. If it's above my max, say the channel cant work

Price per hour is a really crap way to pick a model. I put 2.5bn tokens through Astra and Fable on actual real world dev work. pre opus 5.5. Astra was about 45% cheaper per hour and Fable was burning my plan 3x faster. Fable still runs agents, For me its about 5x better at it

Most developer tools could learn a lot from ecommerce. I’ve done 10m in ecommerce sales and sold a 7-figure brand marketing agency. A devtool can be deeply technical and still need a customer journey that makes sense.

Then look at the moments that feel risky. Connecting a repo, inviting a team or entering payment details can feel like a bigger commitment than founders expect. Say what access you need, what happens next and what the user gets.

You don’t need to turn your product into a marketing site. Treat onboarding like part of the product. Walk through it yourself and count every decision users make before they get something useful.
