GrowthStack builds and runs done-for-you outbound for early-stage B2B startups. We set up your cold email and LinkedIn system, build your lead lists, and manage campaigns monthly — so founders book meetings without doing it themselves. From zero to live campaign in 10 business days, from $2,500.
Used by B2B founders in the US, UK, and East Africa to build their first reliable outbound motion.
That's exactly the problem GrowthStack exists to solve.
We build your entire outbound system from scratch — ICP definition, verified lead list, CRM setup, email infrastructure, and sequences written and live. You get a working campaign before we hand anything over.
We run your campaigns every month. New leads added, sequences optimised, replies handled, meetings booked. You get a clear weekly report. You run the calls. We do everything else.
Phase 1 → Phase 2 — most clients move from setup to ongoing management automatically. See full pricing →
We're specific about scope because it's the only way to deliver consistent results.
We book the meeting. You run the call.
The same modern GTM stack as the best in-house teams — built to last and not locked to us.
GrowthStack builds and runs done-for-you outbound sales systems for early-stage B2B startups. We set up your cold email and LinkedIn outreach infrastructure, write the sequences, build your lead lists, and manage campaigns monthly — so you book meetings without doing it yourself.
The GTM Foundation — a one-time setup that gets your outbound system built and live — starts at $2,500. The Outbound Management monthly retainer starts at $1,500 per month.
The GTM Foundation is completed in 10 to 15 business days. That covers ICP definition, lead list building, email infrastructure, sequence writing, and the first campaign going live.
GrowthStack is built for B2B startup founders who have recently raised (pre-seed to Series A) and need a working outbound motion but can't yet justify a full-time SDR hire.
Yes. A fully loaded junior SDR in the US costs $7,000–$10,000 per month in year one. GrowthStack's setup plus retainer costs a fraction of that, with results starting in weeks rather than months.
Yes. All sending domains, inboxes, CRM configurations, sequences, and contacts are built on your own accounts. If you end the engagement, you keep everything.

No pitch deck. No proposal until you ask. Just a useful conversation.
