Proof of Scale
Turn product-market fit into market momentum
The full brand and marketing system for AI-native companies at Series A — diagnostic, positioning, identity, website, and campaign, all built to turn positioning into pipeline.
The problem
Early adopters bought your vision. The mainstream market buys proof that the product solves a real problem, from a company they can trust.
The referral wave that got you here won't carry you there, and the positioning that worked at seed isn't sharp enough to acquire customers efficiently now.
Most teams respond by hiring fast and shipping tactics — a new site, some ads, a fractional CMO — then rebuild it all months later. Proof of Scale starts where that skips: diagnosing what's actually holding back acquisition, before a dollar goes into execution.
What it is
Proof of Scale is our full brand and marketing system — built to turn positioning into pipeline.
Strategy first
A diagnostic, leadership and customer interviews, and the positioning and messaging that make your product easy to buy.
Build second
Visual identity system, a marketing website, a campaign that converts demand into growth, and an AI-ready BrandOS.
Every deliverable serves one outcome — customer acquisition.

Who it's for
AI-native companies at or around Series A who've found product-market fit and are ready to win the mainstream market. We work directly with founder CEOs and their first marketing hire.
Common triggers:
Series A just closed
Fundraise is 6–12 months out
First marketing hire
Push into a new segment
Marketing investment isn't compounding into growth
If you're pre-product-market fit or just want a logo refresh, this isn't the right fit.
How it works
Timeline
Proof of Scale engagements run 3-5 months, depending on implementation scope.
Onboarding
Your marketing lead spends about 2 hours gathering materials. Leadership answers a short positioning survey. Your CEO sits for a 1-hour interview.
Weekly milestones
We kick-off every engagement with a clear timeline and weekly milestones.
Shared Slack channel
From day one, we set up a shared Slack channel for direct, open communication.
Async weekly updates
Before each review, we send a Loom walking through our thinking so you have time to digest and discuss internally.
Standing weekly meeting
We meet weekly to discuss the work and make decisions together.
