Missed pipeline. Investor pressure. Months trying to run outbound between product meetings and fundraising. It's a familiar problem — and it's entirely fixable.
We started doing this work the way most agencies do — informally. Setting up HubSpot for a founder who'd been putting it off for six months. Building a cold outbound system for a UK financial services company that had never done it before. Configuring Apollo for a luxury hospitality business in Tanzania trying to reach corporate buyers in Europe.
Different industries, different geographies, same core problem: they had a good product and no reliable way to get in front of the right people.
GrowthStack is what happens when you systematise those lessons into a repeatable offer — one that starts fast, delivers results, and keeps running after the setup is done.
Every engagement starts with Phase 1 because campaigns built on weak foundations fail. Wrong ICP, unverified lists, poor deliverability — these aren't minor issues. They're the reason most cold outbound doesn't work.
Most outbound agencies operate in one market. We've run campaigns for B2B companies in the US, UK, and East Africa. If your buyers are in London and your company is in Nairobi, we understand both sides of that conversation.
We're a small team by design. Every client works directly with the people building and running their campaigns. That changes the speed of decisions, the quality of the copy, and the honesty of the reporting.
When you work with GrowthStack, you work with the people doing the work.
Founder-led delivery. Every campaign is built and run by senior people — not handed off to a junior account manager after the kickoff call.
