The SaaS moat is disappearing
For twenty years, software's advantage was simple: write it once, distribute it infinitely. That asymmetry is now collapsing. Foundation models have commoditised the production of code and logic. The marginal cost of building software is approaching zero, and the SaaS multiple was a scarcity premium.
In professional services — legal, accounting, healthcare, finance — a large service market sits directly above a software layer. Founders have tried to attack from below for a generation. The attack from above is now possible: replace the service itself.
The tool is no longer the moat. The delivery of the completed outcome is.
The 3H model: what cannot be automated
Our first filter for every company we consider building. If a task clears all three — no Hands, Hearts, or Handcuffs — it can be delivered by an agentic system at zero marginal cost.
Hands
Most professional services are knowledge work delivered through a screen or document. Legal drafting, accounting review, financial analysis — no physical hands required.
Hearts
Most back-office delivery is output-oriented, not relationship-oriented. A VAT return, a compliance check, a contract review: the client wants the outcome, not the relationship.
Handcuffs
Many regulated tasks require a licensed human to sign off, but not to do the work. The AI does 95% of the work; the human handles liability. That is the structure we back.
Three paths to market
Within the autonomous services thesis, three business model architectures, each with different capital efficiency, margin structure, and defensibility.
Business in a box
Toolkits for independent professionals that automate the back office of their practice. Revenue scales with automation depth, not headcount. Best for fragmented markets with individual practitioners.
Full-stack provider
Own the end-to-end delivery of the service outcome. A services business with software margins — every model improvement drops straight to the bottom line. Best for well-defined, repeatable outputs.
AI-enabled roll-up
Acquire legacy service firms at 5–15% EBITDA margins and replace the back office with agentic systems. The distribution is already built. The AI is the margin engine. The most capital-efficient path in certain verticals.
