SDR & Outbound Sales for Seed-Stage Startups

You've raised seed capital and now have 18–24 months to prove you can build a repeatable, scalable marketing motion. This is the make-or-break stage for most startups.

You've closed your seed round and need to find repeatable channels before Series A. Time and runway are your scarcest resources.

At the Seed stage, your marketing priority should be: Channel experimentation, ICP refinement, and building the demand gen engine that proves product-market fit. Seed stage is about channel experimentation with discipline: test 3–4 channels, measure rigorously, double down on what converts, and kill what doesn't. We build the testing framework and run the experiments.

⚠️ The Seed Marketing Trap

Seed-stage companies waste the most money on premature channel scaling. They find something that works at small scale and immediately pour budget in — before the unit economics are validated. We help you prove before you pour.
