The premise: not more — sound
Most business education optimizes for more. More leads, more offers, more content, more scale. That school of thought has been taught brilliantly, at enormous volume, and if your only bottleneck is attention, it works.
But most operators aren't short on tactics. They're short on durability: customers who stay, referrals that compound, systems that don't break the week you look away, the right move made in the right season instead of the loudest move made now. That is the work of Foundry School, founded in February 2026 by Evan Kirsch and Nic Peterson. A durable business is forged, not hacked.
Seasons are the organizing principle
The Foundry runs on a seasonal cycle, drawn from the temporal doctrine in Seasonal Intelligence: the same work pays differently in different seasons, and fighting the season is the most expensive mistake an operator can make. So the work is organized by season instead of by an arbitrary curriculum. Each season has a focus — one body of work from the library — and everyone works it at the level their business requires, revisiting as the cycle turns.
The backbone is the practice
Underneath the seasons sits The Foundry — a connected body of doctrines built over years of operating real companies. No single framework is the backbone. The backbone is the practice: real operators applying the full library to their own business, season after season, together.
The six doctrines
The library answers six questions, in six works:
- Values — Bumpers. What do you actually want? Everything else is downstream of your answer.
- Execution — Engage the Field (ETF). How do you go get it — deliberately, daily, in the field rather than in your head.
- Reliability — Why It Keeps Breaking. Why businesses fail in ways their owners can't predict, and the math to fix it.
- Growth — R3. How growth compounds from the customers you already have.
- Communication — Stealth Influence. How to move people without manipulating them.
- Timing — Seasonal Intelligence. When to do what — the doctrine behind the seasonal structure itself.
The works connect, but each one stands alone. The spine of the practice is the first three, in order: values, execution, reliability.
R3 is the growth doctrine, not the framework
R3 stands for Retention, Referrals, and Raving Fans: the principle that durable growth comes from the customers you already have — keeping them, being sent their friends, and earning advocates — before it comes from buying strangers' attention. R3 is one doctrine within The Foundry, not its backbone; it is what you apply once values, execution, and reliability are in place. Its companion, R3OAS — R3 On Advertising Spend, created by Laurel Portié with Nic Peterson — runs the same principle on top of paid traffic, so every advertising dollar compounds instead of evaporating.
Where the work happens: the 540
Foundry School membership is open to everyone, with no cap. The seasonal work itself happens inside an enrollment that is permanently capped at 540 people, through two instruments. The Arena is the live working room — one hour every Thursday, three practice sessions each month and The Arena proper on the last Thursday, where members work the current season's material out loud: real numbers, real decisions, real problems, nothing pitched. The Ascent Letter is the written thread — a physical, printed letter working one real problem to the ground per edition, carrying each season's thinking between rooms. Alignment is what keeps a room of hundreds intimate: everyone is working the same concept, in the same season, rowing in the same direction.
Why this differs from typical business education
Foundry School is built for owners and operators of real, revenue-producing businesses, not for audiences. It does not promise a guaranteed-growth playbook, and it does not assume every operator should be scaling at every moment. It is built for what happens after the customer says yes: retention over reacquisition, referrals over reach, reliability over velocity, the right move in the right season over the loudest move now.
