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.
One-time setup · 10–15 business days
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.
Monthly retainer · Ongoing
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.
Here's what we hear on almost every discovery call — and what we do about it.
Real results from early-stage B2B founders across the US, UK, and East Africa.
“We went from 0 qualified meetings to 12 in just 2 weeks. GrowthStack nailed our ICP and the response rates blew us away. I wish we had done this from day one.”
“We were struggling to crack the UK and EU markets with outbound. GrowthStack understood our regional nuances and delivered 28 qualified leads in the first month.”
“Our cold email response rate went from 2% to 8.7% in the first month. GrowthStack automated what we'd been doing manually for months and built a system that actually scales.”
“As a non-technical founder, I needed someone to handle outbound end-to-end. GrowthStack had professional campaigns live in 10 days. That first month changed everything.”
“The integration between their tools is seamless. No more context switching between Clay, n8n, and HubSpot. We scaled from pilot to 45 opportunities a month within two quarters.”
“We've run outbound campaigns for startups in the US, UK, and East Africa. B2B is B2B — the fundamentals work everywhere.”— GrowthStack
