GTM engineering
GTM engineering, built in your CRM and handed to your team.
The data, signals, routing and drafting behind outbound, wired together once and run every morning. Enrichment and verified contacts where they help, judgment on fit and timing before anything is written, and a named person approving every send.
What it is
The machinery under your pipeline.
Most outbound fails upstream of the message. The list was bought, the fit was guessed, the timing was random, and the opener had nothing true to say. GTM engineering fixes that part: who is worth contacting, why now, through whom, and what is true enough to say.
We build it as a pipeline that runs every morning. Market signals come in with dates and sources. Each company is judged on fit, attainability and route separately. The warmest path to a decision maker is found through your own network. The opener is drafted in your voice and filed for approval in the CRM your team already uses.
The pipeline
Six steps, every morning.
Read the market
Funding, senior hires, launches, leadership changes and job posts, each with a date and a source.
Judge each company
Your ideal customer written as plain yes and no definitions, applied to every company the same way.
Fill the gaps
Company and contact data from enrichment providers such as Clay, and verified emails from providers such as Hunter, only where it changes a decision.
Find the way in
LinkedIn degree, mutual connections and past threads, so the first touch is as warm as it can be.
Write the opener
One angle per company, in your voice, with every claim tied to a source.
A person sends
Drafts land in your CRM or outbox. A named person approves. Every send has a receipt.
Proof
In our own run, one in ten companies contacted booked a call in the first week. The same system judged 21,927 companies for one client's market before a single message went out, and found 112 contactable buyers across 14 countries for another. Read the case study.
Where it runs
- HubSpot, Pipedrive or Attio as the record
- Gmail or Outlook for drafts and sends
- LinkedIn for routes and context
- Clay tables, if your team already runs them

Beyond outbound
The same memory runs the rest of growth.
Once acquisition is running, content can turn what ships and what buyers ask into pieces, social can put them in front of the accounts it targets, and ads can scale the messages that already get replies.
