Stackmates
Shared coordination infrastructure so AI-native ventures skip the 12-month stack tax
12 Months Before Your First Customer
Every AI-native venture rebuilds the same unglamorous five. Auth. Payments. Data. Compliance. Tooling. Twelve to eighteen months before domain value ships. The stack tax is real and almost nobody talks about it.
12-18 months
Stack tax before first customer
208 tables
Infrastructure already built
$0
Rebuilding cost for ventures 2-7
Solved Once. Shared.
The unglamorous five exist in every venture. We built them once. Now they compound.
Auth
Identity, sessions, permissions, MFA, OAuth. Solved once, shared across every venture.
Payments
Subscriptions, invoicing, metered billing, tax. One integration. Seven ventures.
Data
208 tables, 10-layer hex architecture, Drizzle + PostgreSQL. Already commissioned.
Compliance
Audit trails, data sovereignty, privacy controls. Built into the domain model.
Tooling
CI/CD, monitoring, deployment, agent coordination. One pipeline, shared infrastructure.

Tight Five
Why does this matter?
Rebuilding commodity infrastructure kills ventures.
What truths guide you?
Strike squads need platform not headcount.
What do you control?
One substrate, seven ventures, no rebuilding.
What do you see others don't?
Commissioned capabilities, not slide decks.
How do you know it's working?
Every completed job improves the next.
Transparency
$0 MRR. No external teams onboarded. These scores measure conviction, not proof. The infrastructure exists. The demand is unverified.
5P Feedback
Critical Metrics
Need external team to validate onboarding
Need 3+ ventures actively using platform
$0 revenue, $500/mo burn
Kill Criteria
Three signals. If any trigger, we stop. Not excuses — decision gates.
Zero external teams onboarded
Month 6 (September 2026)No team outside founder uses the platform after 6 months of availability
Second venture slower than first
Month 9 (December 2026)Next venture launch takes longer than BerleyTrails
Zero willingness to pay
Month 6 (September 2026)5 qualified conversations, zero pricing interest
We did the 12 months. You start at month 13.

Questions
If the infrastructure exists and the thesis is right, why has no external team onboarded yet?
- Which of the unglamorous five is the highest-friction first step for an external team?
- If onboarding takes 40+ hours for the first team, is the problem the platform or the docs?
- Which kill signal would trigger fastest — and what would that tell you about the thesis?
- Does the VSaaS model work without a community, or does community compound the model?

I'm being asked to evaluate a venture called Stackmates. THE THESIS: Most AI-native ventures spend their first 12 months rebuilding the same 5 unglamorous foundations — Auth, Payments, Data, Compliance, Tooling. Stackmates is shared coordination infrastructure so the next venture starts at month 13, not month 1. CURRENT STATE: The infrastructure is built. 208 database tables, 10-layer hexagonal architecture, Drizzle + PostgreSQL. Already commissioned. Burn is NZD $500/month. Break-even Month 8 in the base case. THE OPEN QUESTION ON THE PAGE: If the infrastructure exists and the thesis is right, why has no external team onboarded yet? THE THREE SUB-QUESTIONS THE PAGE RAISES: Which of the unglamorous five (Auth, Payments, Data, Compliance, Tooling) is the highest-friction first step for an external team? If onboarding takes 40+ hours for the first team, is the problem the platform or the docs? Does the VSaaS model work without a community, or does community compound the model? What would have to be true about Stackmates for me to back it? What are the 3 strongest counter-arguments I should raise before committing time or capital? What single piece of evidence would move me from "interesting" to "in"?
