A revenue stack, engineered.

We migrate teams onto Attio and wire it into Clay, Lemlist and Apollo. One specialist, one system, and a working pipeline at the end of the week.

The work

A GTM engineer is what you actually needed.

Most CRM rollouts stall in the same places. The data import that "should take a few hours" eats two weeks. The Clay enrichment everyone demos never quite ships. The handoff from outbound to sales sits in three different tools and one shared Notion page.

We do this for a living. One engineer, one system, and a working stack at the end of the week — Attio configured properly, Clay on a real waterfall, Lemlist and Apollo wired in where they belong.

01 / Migrate

CRM migration to Attio

Reversible, lossless, scripted. From HubSpot, Salesforce, Pipedrive, Folk, Copper or Monday — we keep every field, association and timeline event.


See migration paths
02 / Engineer

Attio implementation

Data model, views, permissions, automations. Built the way an engineer would have built it the first time, with documentation you can actually read.


What's in scope
03 / Wire

Clay · Lemlist · Apollo

Enrichment waterfalls, sequence handoff, deduplication and signal routing. The pieces most teams stitch together with hope and webhooks.

Why one day, not two weeks

Our own AI-powered system, refined across 23 migrations.

Every migration we run is a single, reviewable command. Years of experience baked into a system that maps every object, every association, every custom field — then prints a diff before it touches your Attio workspace. Nothing copies until you say "go".

  • Dry-run first. See exactly what will land in Attio before any write happens.
  • Idempotent. Re-run safely. Failed rows are quarantined, not duplicated.
  • Auditable. Every record carries a source ID and a migration timestamp.

FAQ

Questions we get on every call.

How can a migration finish in a single day?+
Our own system does the heavy lifting. We've run it across 23 migrations, so the field-mapping for HubSpot, Salesforce, Pipedrive, Folk, Copper and Monday is already built — what's left is your specific custom fields. The actual migration window is usually under 30 minutes; the rest of the day is verification.
What does "GTM engineer" mean, exactly?+
Someone who treats your revenue stack like infrastructure. Same discipline, same tooling, same expectation that things should be reproducible and reviewable.
Do you only work with Attio?+
Yes. Specialisation is the point — it's how we keep migrations to a day instead of a fortnight.
How are you priced?+
Fixed-price packages by scope. You get the quote in your scoping doc before any work starts, and we don't bill hourly extensions.
Will my team be able to maintain this after you leave?+
Yes — that's the deliverable. You get a written runbook, Loom walkthroughs of every workflow, and a 30-day window for follow-up questions.
