The problem
Founder dependency, disconnected channels, no shared acquisition narrative, reporting that tracks activity instead of outcomes.
Cornerstone
Growth operating system.
The Growth Bottleneck System is the named WSS model for post-PMF teams: diagnose the bottleneck, build the acquisition engine, and transfer the weekly rhythm — so growth stops depending on founder heroics.
Why it matters
Post-PMF startups usually die in the middle.
You have traction. But pipeline arrives in bursts. The founder is still the best salesperson. Channels are running in isolation. Nobody can confidently say what's working.
The system solution
One coherent operating system: diagnosis → design → build → transfer. Not a deck, a working growth function.
Four phases
How the system is built.
Diagnosis
Bottleneck constraint mapping across five layers: positioning, acquisition, conversion, reporting, team ownership.
Design
Acquisition system architecture: channel strategy, offer map, landing briefs, and reporting cadence.
Build
Channel execution, campaign logs, experiment backlog, and weekly decision rules.
Transfer
Playbooks, dashboards, handoff packs, and weekly rhythm that runs without founder involvement.
What you get
Working artefacts, not slide decks.
Who this is for
Post-PMF B2B SaaS and AI startups.
Seed to Series A
Founder still owns every revenue call. Pipeline is inconsistent. Need to professionalise acquisition.
Series B+
Growing team but no shared growth operating rhythm. Channels sprawling. Need system before full-time CMO.
AI-native startups
Great product, unclear GTM. Need to separate AI hype from commercial acquisition reality.
