GTM systems for B2B SaaS

Your entire GTM pipeline, running as one system.

Stackform builds go-to-market engines on the tools you already pay for. Outbound that gets replies, inbound answered in seconds, and every lead routed, followed up and logged without anyone chasing it.

No new platform to learn. Built on your existing stack.

To: founder@acme.io

Hi Sarah, noticed you just became the sole active director at Acme, which usually means GTM lands on your plate now.

I put together one specific way to take first-response off it. Want me to send it over?

The gap

You bought the stack. It's sitting half-idle.

Most teams already pay for the tools below and still answer inbound late, run outbound by hand, lose track of who owns which lead, and find out a deal went quiet three weeks too late. The tools aren't the problem. The missing system is.

Sound familiar?

The five ways GTM quietly breaks at this stage.

Almost every seed to Series A team I speak to is living one of these. Usually two.

I'll get some outreach done this weekend, promise.

The founder is the sales team, doing outbound in the gaps between everything else. Some weeks it happens, most weeks it doesn't, and pipeline swings with the founder's calendar.

The fix · an outbound engine that runs whether you're in the room or not

We got back to them Tuesday. They'd already booked two other demos.

Inbound comes in from the site, ads or referrals, then sits in an inbox until someone's free. By the time a human replies, the buyer has moved on or gone cold.

The fix · instant response, qualification and booking, 24/7

We pay for Clay. Nobody's opened it since March.

The stack got bought in a burst of ambition: enrichment, sequencer, CRM. Then nobody had time to wire it together, so it sits half-configured while everything still runs on spreadsheets.

The fix · your existing tools connected into one working pipeline

I thought you were chasing that one.

The second rep joined and handoffs are still verbal. Two people touch the same leads, nobody formally owns follow-up, and the highest-value deals are the ones that slip because everyone assumed someone else had it.

The fix · ownership rules, handoff logic and gone-quiet alerts

We sent 5,000 emails last month. Three replies.

Outbound means blasting a bought list with the same opener. Reply rates flatline, the domain reputation takes the damage, and the conclusion drawn is that outbound doesn't work.

The fix · signal-scored, researched outreach at capped volume

Honestly, the CRM is fiction at this point.

Deals live in inboxes and heads. The CRM exists but nobody trusts it, so forecasting is guesswork and every investor update means an afternoon of archaeology.

The fix · a pipeline that logs and updates itself as leads move

What Stackform builds

The full pipeline, from first touch to closed. Systemised.

You already own the tools. Stackform connects them into one GTM engine: demand in, meetings booked, pipeline kept clean, nothing slipping in between.

Outbound engine

Outreach that earns the reply

Lists built and enriched, every message led by a real signal, not a mail-merge blast. Weak signals get ruled out instead of forced. Sequences run at capped volume, so replies come in without your domain getting burned.

Inbound response

No enquiry waits till Monday

Every inbound lead answered in under 60 seconds. Qualified, routed to the right person, and booked straight into the calendar. Day, night, weekend. The lead's locked in before they shop around.

Nothing slips after the handoff

Clear ownership on every lead, automatic follow-up rules, alerts when a deal goes quiet, and a CRM that stays accurate on its own. Handoffs stop being verbal, and nobody assumes someone else is chasing.

How working together goes

Scoped in a call. Built in weeks. Handed over running.

01 · Scope

A 30-minute diagnosis

We walk through how leads move today: where they come in, what's manual, where they slip. Within 48 hours you get a written scope of exactly what I'd build, with the stack, timeline and price.

02 · Build

Built on what you own

I assemble the system on the tools you already pay for, test it on real leads, and nothing sends without your sign-off on messaging.

03 · Handover

Yours, documented, running

You get the working system, a walkthrough video, and written rules for how it behaves. No dependency on me to keep it alive, though I'll stay on to run and tune it if you want.

"Seriously thorough. The signal scoring was well thought out, and weak signals got ruled out instead of forced into an angle. That's exactly what separates real outreach from spam."

Founder, EmailFixer

Before

A pile of signals, no clear angle

Director listings, company filings, role titles. Plenty of surface-level data, but no view on which problem was actually safe to lead with. Any angle would have been a guess.

After

One defensible angle, with reasoning

Broken down, only one signal was strong enough to act on: the founder becoming sole active director. Weaker signals ruled out, with clear reasoning for the one chosen. One sharp message instead of five vague ones.

Before you ask

The honest answers.

Isn't automated outreach just spam?

That's exactly what I build against. Every message is led by a real, researched signal, and weak signals get ruled out rather than forced into an angle. The automation handles the boring parts, finding, enriching, sequencing, not the thinking. The result reads like a person sent it, because the judgment behind it was real.

Do I have to switch tools or learn a platform?

No. I build on the stack you already pay for: Clay, Apollo, your CRM, your sequencer, your calendar. Nothing to migrate, nothing new to log into. You get a working system, handed over running.

We already have a setup. What would you actually do?

Most teams own the tools but never connected them into a system, so leads still slip and outbound still runs by hand. I find the gaps: slow inbound response, no routing, manual sequencing. Then I wire it into one pipeline that actually moves a lead from contact to booked call.

How fast can it be live?

The core inbound-response system is usually live within days, because it's built on what you already have. Outbound takes a little longer. The research and signal work is the part worth getting right.

What does it cost?

Builds are fixed-price, scoped upfront, so there's no meter running. The exact number depends on the system, and it's in the written scope you get after the first call. If you want it run and tuned after handover, that's a small monthly retainer, and the first month's on me.

Taking on a small number of founding clients

Let's see what your stack should be doing.

A short call. I'll look at how your inbound and outbound run today and show you the system that closes the gaps. You'll have a written scope within 48 hours.
