Sound familiar?

Funded, growing, and pipeline still runs on hustle.

Most B2B teams already have the tools. They were never connected into a system that creates pipeline on repeat.

“We raised. Now the board wants pipeline, fast.”

What we build: Signal-based prospecting that surfaces in-market accounts every week.

“Reps build lists by hand and guess who to call.”

What we build: ICP scoring and enrichment, so reps start with the right accounts.

“Inbound leads wait hours before anyone replies.”

What we build: Instant enrichment and routing, with alerts to the right rep.

“We bought the tools. Nobody connected them.”

What we build: One system across your CRM, Clay and AI agents, with training so it gets used.

The signal layer

Reach accounts when they're ready, not when your list says so.

Every system we build starts with signals. When one fires, the account is enriched, scored and routed in minutes.

What GTM engineering really is

More than Clay tables.

A Clay table is one tool in the system. GTM engineering is the whole stack behind it: starting with your market map, then the data, the company brain, the agents that act on it, and where the output lands. We build all five layers, in your stack.

1Market mapDefine your ICP and build your total addressable market, account by account.
  • ✓ICP and personas
  • ✓TAM list, tiered A to C
2Data foundationFirst- and third-party data in one clean record.
  • ✓Deduped CRM
  • ✓Multi-source enrichment
3Company brainThe context your team and AI work from.
  • ✓Positioning and proof
  • ✓Won and lost history
4AgentsSignals trigger research, scoring and routing.
  • ✓Claude Code, Cursor, Grok
  • ✓Human review on key sends
5ActivationOutput lands where your team already works.
  • ✓Outbound, ads, call prep
  • ✓CRM and Slack updates
First-party data · you own itYour strongest signal, usually unused.
  • ✓CRM records, deal history and closed-lost notes
  • ✓Website visits, form fills and product usage
  • ✓Call transcripts, email replies and event attendance
  • ✓Past customers and champions
Third-party data · you source itFills the gaps and spots who's moving.
  • ✓Firmographics and technographics
  • ✓Hiring, funding and leadership changes
  • ✓Job moves and buying-committee changes
  • ✓Category intent and review-site research

We combine both, refresh only the fields that matter, so you aren't paying to re-enrich everything, and feed the result into the company brain.

The self-learning revenue engine

A system that gets smarter every quarter.

Most GTM systems are built once and slowly decay. Ours close the loop: every win, loss, reply and rep edit goes back into the company brain, so targeting, scoring and messaging improve over time.

  • ✓Won and lost deals show which signals actually led to revenue
  • ✓Rep edits to AI drafts are captured and used to improve the next one
  • ✓Scoring and messaging updates are proposed, then your team approves them
  • ✓Everything is versioned and documented, so nothing changes silently

How it works

Clay is the engine. Your CRM is home base.

Data comes in, Clay and AI agents built with Claude Code, Cursor and Grok work out what it means, and your CRM is where your team acts on it. Each one runs as a repeatable motion.

Step 1

Data in

Signals, website activity, CRM records and your target account list.

Step 2

Clay workflow

Waterfall enrichment, AI research and ICP scoring decide who matters and why.

Step 3

Back into your CRM

Routing, sequences, tasks and reporting, so reps act and you see the result.

FAQ

GTM engineering, answered.

What is GTM engineering?

GTM engineering is building the systems behind your go-to-market: data, buying signals, enrichment, scoring, routing and automation. Instead of reps working static lists, a GTM engineer connects tools like Clay and HubSpot so the right accounts are found, researched and reached automatically, and every step is measured in pipeline.

Is GTM engineering just building Clay tables?

No. Clay is often the orchestration layer, but GTM engineering covers the whole system: a clean data foundation, a company brain your AI works from, agents and workflows that act on signals, and the feedback loop that measures what turned into revenue. A table nobody owns, or that never writes back to your CRM, doesn't change your pipeline.

What is a company brain?

It's the shared context your team and your AI agents work from: your ICP and personas, positioning and proof points, playbooks, call notes, and the history of what you won and lost and why. Without it, AI writes generic outreach. With it, every draft, score and route reflects how your company actually sells.

What's the difference between first-party and third-party data?

First-party data is what you already own: CRM records, website visits, product usage, call transcripts and email replies. Third-party data is sourced from outside: firmographics, technographics, hiring, funding, job moves and intent. The strongest systems combine both, with first-party signals usually the most predictive and the least used.

What does a GTM engineering agency do?

A GTM engineering agency designs and builds those systems for you. Marketick audits your CRM, data and outbound, then builds workflows for prospecting, inbound routing, signal-based outbound and rep research, and hands them over with documentation so your team owns them.

What are buying signals?

Buying signals are events that show an account may be ready to buy, such as hiring for sales roles, raising funding, changing tech, a champion changing jobs, visiting your pricing page or researching your category. We track these automatically and trigger outreach or routing when one fires.

Do you do data enrichment?

Yes. Data enrichment is the foundation of every GTM system we build. We use Clay to fill in company and contact data from multiple providers in a waterfall, keep HubSpot records accurate with scheduled re-enrichment, and use that data to score, route and personalise outreach.

Do we need Clay?

For most B2B teams, yes. Clay is the strongest tool for waterfall enrichment, AI research and signal tracking. If your volume or budget doesn't justify it, we'll tell you and build with the tools you already have, such as HubSpot, Apollo or n8n.

How does Clay work with HubSpot?

Clay acts as the engine and HubSpot as home base. Clay enriches and scores accounts and contacts, then writes the results back into HubSpot properties, where workflows route leads, start sequences, create tasks and report on pipeline.

Do you work with Salesforce?

Yes. HubSpot is our main platform, but we connect Clay workflows and enrichment to Salesforce as well, and we migrate teams from Salesforce to HubSpot when that's the right move.

How long does a GTM engineering project take?

Timing depends on how many systems you need and the state of your data. We agree a delivery plan after discovery.

Do you work with newly funded startups?

We can help a funded company connect its GTM tools, build workflows and train its team. Book a call to discuss the scope and handover.

Who owns what you build?

You do. Everything is built inside your own Clay and HubSpot accounts, with documentation and training for your team. If you want ongoing help, we offer support, but you're never locked in.
