I got tired of messy business cases — so I built my own tool
Hey — I’m Craig, founder of ProductM8.
After years of working on business cases across different companies, I kept seeing the same problem — good ideas getting lost, and bad ones slipping through, because the thinking wasn’t clear.
I tried using AI to speed things up, but most tools just generate content. They don’t help you actually think — they just fill in the blanks.
So I built something for myself. Then I kept going.
ProductM8 takes a rough idea and walks you through it step by step until you have a complete, structured business case you can actually use.
Business model canvas. Value proposition. Market research. Personas. Risk analysis. All connected, all in one workflow. And when you’re done, you can export the whole thing to PDF, Word, or PowerPoint and share it with whoever needs to see it.
We’ve self-funded everything so far — just focused on building something genuinely useful for founders and product teams.
This is for anyone who’s had an idea and thought, “this could be something” — but didn’t know how to work it through.
👉 Curious — how are you currently working through new ideas or business cases today?

Honestly right now it's just Claude and a Google Doc which works but there's no structure to it. Love the idea of idea of business model canvas. Congrats on the launch!
