Client-owned growth systems for post-PMF B2B teams

Choose GTM System, Conversion System, or Authority Loop. You get the filled tank, the keys, and the operating notes: ready outbound, a conversion asset, or a three-month authority package.

Defined finish line. Working system. Handover date. 1 accountable owner carries the context from diagnosis through QA.

The expensive part is learning which bottleneck actually matters.

A weak offer does not need more sending volume. A website that undersells the company does not need another traffic source. Founder content without a story bank does not need a stricter calendar. The first job is naming the leak correctly.

Market OS turns that diagnosis into a working asset: the campaign logic, site, calculator, or authority package that removes the bottleneck and remains after the project ends. Advice is useful only when it changes what runs on Monday.

Inside GTM Engine / 1 live pass

Market noise in. A named, approved play out.

An example signal, followed end to end. Most of what the system sees, it declines to act on. Every step is inspectable: you can see why it made the next move, and why it refused the ones it did not.

01 Signal

A funding round, a champion changing jobs, a hiring spike. The system watches your market and suppresses the stale, the duplicate, and the out-of-profile.

Example run
Funding round, seed, out of ICPsuppressed
VP Sales joined a target accountmatch
Tech change on a churned domainsuppressed

02 Evidence

The account is enriched, scored against your ICP, and assembled into a brief a human can check in seconds.

Example run
Account
Target account, tier 1
Event
New VP Sales, started this month
ICP score
84 / 100, above threshold

03 Play

A named play from your library is selected for this exact situation. Not a template blast; a move with a reason.

Example run
Play selected

Champion Tracker: reconnect

A known contact changed jobs into a target account. The play drafts a reconnect brief anchored to the past conversation, not a cold template.

04 Human gate

The evidence, play, and draft land in 1 queue. Approval writes the move into your CRM and sequence; rejection stops it. Nothing sends itself.

Agencies rent you a stack. Market OS hands you the keys.

Rented

  • The playbook leaves when the agency does
  • Tools billed monthly, logic hidden
  • Reporting explains activity, not decisions
  • Every new campaign starts from 0

Owned

  • Your implementation lives in your stack and stays there
  • Every signal, rule, gate, and output is inspectable
  • Your team runs it; continuity is optional by design
  • Each campaign compounds into the next

The split is explicit: you own your client-specific implementation outright, and Market OS keeps the factory that builds installs. The incentives point the same way as yours: the business earns on the next install, not on your dependence. If the system needed its builder forever, it was not built properly.

Start with the teardown. Go further only on evidence.

  1. Step 1

    The teardown

    A focused review of your whole motion: positioning, website, content, outbound, data, and routing. The deliverable is the diagnosis and the first experiment.

  2. Step 2

    The Rematch

    Your current best campaign or page against a Market OS rebuild, on an agreed baseline and denominator. Raw counts decide it, and the rebuild stays with you either way.

  3. Step 3

    The build

    Whichever system the diagnosis calls for: GTM System, Conversion System, or Authority Loop. Built against a written finish line, then handed over.

1 senior operator. No handoffs.

Market OS is built and installed by Mark Kurick, whose work across 50+ companies spans campaigns, websites, growth tools, venture building, and GTM infrastructure in 4 working languages. The same person who diagnoses the bottleneck builds the asset, which also means projects run in sequence: capacity is real, and finite.

The teardown reviews your ICP, offer, data, signals, deliverability, copy, and routing. You leave with the diagnosis and the first experiment, whether or not we go further.
