Head of Growth
Thera (YC S22)
Sales & Business Development
Posted on Feb 21, 2026
The Role
We are hiring a Head of Growth to own the experiment engine. This is a hands-on role for someone who has built growth loops before and wants to do it again with a product that has real traction and real customers.
You will own activation, retention, referrals, and channel expansion. You will work closely with the CEO, product, and operations to find the fastest path to more revenue. The job is not to have all the answers. It is to test fast, learn faster, and scale what works.
What You'll Own

We are backed by Y Combinator, 10X Founders, Zillionize, and Amino Capital. We sell into real operators. Founders, finance leaders, and business owners who care about execution, trust, and saving time.
