A full GTM engine - built live, no slides, real fight to get open-source to market in 2 hours! 🔥

Leszek is the founder of Lammel Advisory and finished 2nd at Clay Cup 2026, the world final in San Francisco.

I'm bringing him a challenge - build me a GTM Engine for newly released open-source product.

True 0 to 1 - we'll fight together to define ICP, positioning, build & enrich lists, find signals and send first outreach.

GTM Battle at it's finest - join us, have fun and learn. Or even build alongside us 😎

We'll do many fckups, the work will be totally unfiltered, you'll see all behind the scenes

For founders, GTM engineers, sales and marketing operators who want to see how the pieces fit together
