The story of Xaiku - Copy testing shouldn't require an enterprise contract.

At Persado I saw what happens when you bring NLP and emotional analysis to marketing copy. It worked. Really well. But the whole thing was built for Fortune 500 companies — six-figure contracts, months of onboarding, big sales teams flying to the US to close deals. If you were a solo founder or a small team, none of that was for you.

I always wanted to build a self-serve version of that. Something where you just sign up, describe what you're working on, and get real copy variants with emotion analysis and A/B testing built in. No demo calls, no "contact sales" buttons.

The thing that held me back was simple: I'm a product engineer, not a sales organization. I could build the product, but I couldn't also do enterprise sales and marketing on my own. Then AI changed the equation. The pieces I was missing suddenly became possible for a team of one. So I built the thing.

Xaiku is small, independent, and funded by the people who use it. I want to keep it that way. I'd rather build something focused and honest than play pretend at being a big company.

I hope you enjoy using it as much as I enjoy building it.
