Seed-to-Series-A Growth Hacking Afterwork

A swap shop for founders and operators between seed and Series A — bring one growth experiment, what it cost, and what happened.

About the Evening

What actually moved your numbers? Yorkseed and Tison.io are hosting a swap shop for founders and operators between seed and Series A. Bring one growth experiment you ran — say what you expected, what happened, and what it cost.

The failed ones are usually more useful than the wins, so bring those too. Drop in whenever you finish work.
