For B2B Startups That Just Raised

You raised.
Now you need pipeline.

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.

Sound Familiar?

Most founders know they need outbound.
Almost none have time to build it right.

"I've been meaning to sort out outbound for months. It keeps getting pushed back."
"I tried cold email myself. Low reply rates. Not sure what went wrong."
"Hiring an SDR costs $5–7K/month and takes 90 days to ramp. Not ready for that."
"I'm using Apollo, Instantly, and HubSpot — but they don't really talk to each other."
"We just raised. Investors are asking about pipeline. I want a better answer."

That's exactly the problem GrowthStack exists to solve.

How It Works

Two phases. One motion.
No loose tools to manage.

Phase 1

GTM Foundation

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.

From $2,500 one-time
Phase 2

Outbound Management

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.

From $1,500 / month

Phase 1 → Phase 2 — most clients move from setup to ongoing management automatically. See full pricing →

✓  Still running sales personally or just hired their first salesperson
✓  Need a working outbound motion, not another tool to manage
✓  Want meetings booked, not activity reports
✓  Can't yet justify a full-time SDR hire ($5,000–7,000/mo)

✗  Not a fit

✗  You already have an established sales team running outbound
✗  You're pre-product and not yet ready to talk to customers

FAQ

Common questions

What does GrowthStack do?

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.

How much does GrowthStack cost?

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.

How quickly can you get outbound running?

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.

Who is GrowthStack for?

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.

Is GrowthStack cheaper than hiring an SDR?

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.

Do I own the system you build?

Yes. All sending domains, inboxes, CRM configurations, sequences, and contacts are built on your own accounts. If you end the engagement, you keep everything.
