GTM Sprint

Test your GTM direction in 2 weeks instead of 2 months

Test your GTM direction in 2 weeks instead of 2 months.

A focused sprint to test ICP, message, and channel combinations. Real signal, real assets, clear learnings. No retainers. No blind guessing.

The problem

You have a product. Some users like it. But you do not know how to reach more of them consistently.

You have tried things. LinkedIn posts, cold emails, maybe a landing page. Some things got responses, others did not. But you do not know why. You do not know which ICP actually converts, which message resonates, or which channel is worth doubling down on.

Every week feels like another random experiment. You are not learning fast enough. And runway keeps shrinking.

  • β€” You do not know which ICP is most receptive
  • β€” You do not know which message angle works
  • β€” You do not know which channel to prioritize
  • β€” You are guessing instead of testing systematically

What we do together

We pick one ICP, one message angle, and one channel. We build the assets, run a real campaign, and measure what happens.

The goal is not to find the answer in 2 weeks. The goal is to get real signal on one combination so you know what to try next, what to adjust, or what to drop.

I do the hands-on work. You stay close so we can move fast and so you understand what we learn.

ICP definition

We pick one target profile to test, with clear signals

Message angle

One positioning and one narrative to put in front of them

Landing page

A focused page built around that message, live and trackable

Channel test

Outbound or ads on one channel, enough volume to get signal

Learnings

What worked, what did not, what to try next

How the sprint works

1. Kick-off

We align on your product, your context, and what you have already tried. We decide which ICP, message, and channel to test first.

2. Build (Week 1)

I write the positioning, build the landing page, and prepare the campaign assets. You review and give feedback. By end of week 1, we are ready to launch.

3. Test (Week 2)

We run the campaign. I track results and adjust if needed. At the end, we debrief: what signal did we get, what does it mean, what should you do next.

Timeline: 2 weeks from kick-off to debrief.

What you walk away with

  • β†’Positioning doc β€” The ICP, message angle, and value prop we tested
  • β†’Live landing page β€” Built around that message, yours to keep and iterate on
  • β†’Campaign assets β€” Outreach sequences or ad creatives, depending on the channel
  • β†’Tracking setup β€” Events configured so you can keep measuring
  • β†’Debrief report β€” What we tested, what signal we got, what to try next

Everything is yours. You can run the next test yourself or bring me back for another sprint.

Who this is for

Good fit

  • β€” Early-stage founder (pre-seed, seed, bootstrapped)
  • β€” Product exists and works for some users
  • β€” You have tried GTM but do not know what works yet
  • β€” You want signal fast, not a 3-month strategy

Not a fit

  • β€” No product yet
  • β€” Enterprise sales with long cycles
  • β€” You want guaranteed pipeline numbers
  • β€” You already know your GTM and need scale

If you are stuck guessing which ICP, message, or channel to focus on, this sprint helps you find out faster.

Why me

I have been on both sides. As a founder, I scaled a cybersecurity accessories brand to 500K units, bootstrapped, across B2C and B2B. I built an AI platform for mid-term rentals and ran city-level GTM.

I know what it feels like to guess which combo works. I also know how much faster you move when you test systematically instead.

I do not give advice from a distance. I build the assets, run the campaigns, and show you what happened.

  • β€” Passed 1M revenue across several businesses
  • β€” Hands-on: outbound, paid, landing pages, positioning
  • β€” Work directly with founders, no layers

Want to run a test?

If you are tired of guessing and want real signal on your GTM, let's talk.

The call is short. We discuss your product, what you have tried, and whether a sprint makes sense. No pressure.
