Legal and Compliance Stack for Under-18 Founders: The Stripe Atlas "Junior" Heist

Build the AngelList for One-Person Businesses
The creator economy is a $250B sector with no real financing infrastructure. Revenue-share agreements plugged into Stripe and Shopify data could become the capital layer for solo founders and micro-SaaS builders.
The Boring Niche Pulling $40 CPMs Hiding Inside Faceless YouTube Channels
Finance YouTube pulls $15–$40 CPMs but generic channels die fast. The real content business idea: a niche tax-and-compliance media layer for one self-employed income tribe — creators, Airbnb hosts, freelancers — with a four-layer revenue stack built on search intent, not virality.

Redaction destroys LLM context. Pseudonymization preserves it. Ship the governance control plane regulated industries will pay six figures for.
The Creator Pension Fund Heist
Spotter raised $200M proving creator catalogs are worth billions. YouTube shipped localization tools that grow them. The operating company is still unbuilt.
TurboTax for HVAC Rebates
California contractors are losing $8,000 rebates to paperwork errors while waiting 90 days for payment. Both problems need middleware.

373,000 volunteer-run associations managing $120B annually with amateur controls and predictable fraud patterns, creating structural demand for purpose-built governance infrastructure.
