Results
The numbers behind the rebuild.
The problem
Where the chain was breaking.
As a technical AI product, reaching the right audience (YouTube creators and media companies) required precision targeting
Previous acquisition channels were expensive and delivered low-quality trials that rarely converted to paid subscriptions
Skepticism around AI tools in the creator space meant ad creative needed to demonstrate clear, tangible value quickly
What we built
The system we put in place.
We built lookalike audiences from their highest-LTV users and targeted YouTube creator communities and media professionals. The ad creative was data-driven: real prediction accuracy and revenue uplift metrics from existing users, not vague AI promises. We optimized the free trial funnel for activation rather than just sign-up, improving trial-to-paid conversion. Educational content positioned the product as a data advantage rather than just another tool in a crowded AI market.
“As a Y Combinator company, we're extremely rigorous about ROI metrics. Meta Ads cut our lead costs by 50% compared to our previous channels. For a technical AI product, we didn't expect Facebook to perform, but the targeting capabilities allowed us to reach exactly the right audience. It's now our highest-performing acquisition channel by a significant margin.”Charles Weill
