The Telos GTM OS

One operating system. Two halves.
Five foundations.

The GTM OS is how we map every client. The customer journey runs across the top. The five disciplines run underneath. Every gap, every fix, every engagement is scoped against this map.

Stage 01
Awareness
// Acquire side
// Where it breaks
Pipeline is thin. Outbound is dying or burning domains. Targeting is scattershot. The market does not know you exist.
// What we build
  • Sharpen ICP, segments, and target account list
  • Channel mix and outbound infrastructure that does not burn domains
  • Messaging tested against real buyer language
  • Awareness funnel measured against real pipeline output
// The five disciplines
01
Strategy
ICP, segmentation, positioning, pricing, GTM plan.
02
People
Org design, hiring, comp, quota, enablement, training.
03
Process
Methodology, playbooks, qualification, deal reviews.
04
Systems
CRM, outbound stack, automation, AI, integrations.
05
Data
Reporting, dashboards, KPIs, forecasting, attribution.
Without strong foundations, every stage downstream leaks.

Stack fluency

We do not just talk tools.

The digital brain
Clay runs the stack.
Clay enriches, scores, and orchestrates every record. It pulls from the data sources, feeds the outbound, and writes back to the CRM. The other tools execute what Clay decides.

What makes us different

Three reasons clients choose Telos.

03 reasons
01
We operate. We do not just advise.
Most advisors deliver decks and disappear. We embed in your team and ship the system. When we leave, the work runs without us.
02
We come from the field.
Fifteen years of B2B SaaS sales, customer success, outbound, and pipeline. Built and run firsthand. Practitioner voice, not consultant voice.
03
We bring an execution arm.
Through ColdComplex, our outbound infrastructure runs at scale. Most advisors talk about outbound. We run it.
Field notes

What we are seeing in the field.

Short, opinionated takes on GTM, outbound, RevOps, and how the stack is changing. Written by operators, not analysts.

Strategy28 April 20264 min read
GTM is no longer a playbook. It is a system.
Most advisors will hand you a playbook. A playbook breaks the moment a market shifts. A system adapts.
Read
Outbound22 April 20265 min read
Outbound did not die. It got commoditised.
Automated outbound at scale broke. What still works is hyper-targeted, multi-domain, and orchestrated by something smarter than a sequence builder.

If your CRM is the source of truth, your GTM is broken.
CRM stores what humans typed. Clay stores what is true. Most stacks have those two reversed.
