About
GTM systems that go the distance.
LongRun is a B2B GTM engineering agency. We build complete outbound systems: domains, mailboxes, Clay data infrastructure, AI-personalized sequences, CRM sync: and hand them over documented. Our clients own their pipeline. They never pay per meeting.
Why we exist
The lead-gen agency model is built to keep you renting.
The industry
Pay-per-meeting keeps you dependent
Most agencies sell appointments. The infrastructure, the data, the learnings: all of it stays on their side, because your dependence is their retention strategy. Stop paying, pipeline stops.
- You rent results instead of owning capability
- Per-meeting pricing rewards junk meetings and volume games
- Cancel and you keep nothing: no data, no domains, no playbook
Our model
Fixed scope, full handover
We charge a fixed retainer to build a system in your name and teach your team to run it. At day 90 you choose: take it in-house or keep us on month-to-month. Either way, every asset is yours.
- Domains, mailboxes and data registered to you from day one
- A documented playbook, SOPs and Loom walkthroughs at handoff
- Our incentive is the system working, not the meeting count

How we work
Principles we don’t bend.
Fixed scope, fixed feeOne retainer, everything included: tools, volume, copy, reporting. No tiered features, no upsells mid-flight.
Built in your nameDomains, mailboxes, Clay tables and CRM automations all live in your accounts from day one.
Warmup is never billedThe first three weeks of infrastructure build and mailbox warmup are free. Billing starts when sending does.
Deliverability over volumePlacement tested every 250 emails; anything below 90% pauses the same day. A burned domain is never worth one more send.
No fake personasReal LinkedIn accounts, real sender names, real compliance. Shortcuts that get accounts flagged aren't shortcuts.
Documented handoverEvery system ships with SOPs, Loom walkthroughs and a playbook your team is trained on at day 90.
Who's behind it
Built and run by an operator, not an account manager.
