Didoo.ai's answer
What inspired me to build this? After years at Alibaba building marketing tools for millions of sellers, I kept seeing the same heartbreaking pattern: brilliant developers launching amazing apps, then watching them die because they couldn't crack Meta ads. They'd burn $5K+ on agencies or spend nights drowning in Facebook's dashboard instead of shipping code. That pain hit home when my developer friend's mental health app (which literally saves lives) shut down - not from product issues, but because he couldn't make ads work.
The evolution was wild. We started as a simple ad generator, but when we saw SMBs getting 0.8% CTR while our AI found angles hitting 3.2%, we realized the real problem wasn't creation - it was the entire growth system. So we rebuilt everything: from scanning customized & precise audiences in seconds, to having our AI agent pause losers within 1 hour, to that sunrise email summarizing what actually moved the needle.
Most proud moment? A solo dev from Lagos messaged that Didoo helped her education app hit 10.8x ROAS, letting her hire 3 teachers. That's when we knew - democratizing Fortune-500 growth isn't just marketing speak. It's giving every indie dev the unfair advantage to focus on building, not bidding.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
