The vocabulary of the LEVERS operating system and the Retrocause fellowship. Bookmark this page — these are the terms we use to describe how a capital-efficient business is built.
Retrocause is a 2-year fellowship for founders building profitable, capital-efficient companies. The program teaches and implements the LEVERS operating system across two full cycles, with monthly cohort masterminds and quarterly 1:1 advisor sessions.
Founded by Amos Schwartzfarb — long-time Techstars Managing Director and author of the Levers book — Retrocause was built to be the anti-accelerator: a program optimized for revenue and profitability instead of the next fundraise.
LEVERS is a 5-step operating system for founders: W3 (Why, Who, What) → Revenue Formula → Assumptions & Prioritization → KPIs → Financial Model. Each step builds on the one before. Run twice over two years, it replaces intuition-driven founder decisions with evidence-driven ones.
LEVERS has been tested across 1,000+ startups. It works at every stage from pre-revenue to $10M+ ARR.
Read more →W3 is the first step of the LEVERS operating system. It forces ruthless clarity on three questions: Why does your business exist? Who specifically do you serve? What do you actually offer them? When W3 is clear, every downstream business decision becomes a simple test.
Read more →The Revenue Formula is the second step of the LEVERS operating system. It decomposes revenue into 3–5 mathematical variables a specific person on your team can measurably influence. Once written down, the growth levers with the highest leverage become obvious.
Example: for e-commerce, Revenue = Traffic × Conversion Rate × Average Order Value × Purchase Frequency. For SaaS, Revenue = Leads × Trial Rate × Trial-to-Paid × Contract Value.
Read more →The third step of the LEVERS operating system. Founders surface every belief their business depends on — pricing assumptions, channel assumptions, persona assumptions — and rank them on two axes: risk if wrong and confidence it's true. Test the high-risk, low-confidence ones first, before betting cash on them.
Read more →The fourth step of the LEVERS operating system. Not vanity metrics. The specific numbers tied to the Revenue Formula that predict — not describe — whether your business is growing. A good KPI dashboard has 2 leading indicators for every 1 lagging indicator.
Read more →The fifth step of the LEVERS operating system. Not a fundraising deck — a living decision-making engine driven by your real Revenue Formula and KPIs. Used weekly to compare actuals to projections and pressure-test every major decision before it's made.
Read more →Capital-efficient growth means building a business that generates more revenue per dollar spent, minimizing dependency on outside funding. It's a discipline that forces clarity, prioritization, and better decisions — not a constraint on ambition.
Capital efficiency is the opposite of the growth-at-all-costs playbook. It optimizes for profitability and longevity over burn-for-market-share.
A company is default alive when it will reach profitability on its current trajectory without needing additional funding. Coined by Paul Graham, it's the mode Retrocause helps founders achieve through the LEVERS operating system.
The Retrocause Fellowship is a 2-year implementation container for the LEVERS operating system. Founders complete all five steps in Month 1, then spend the next 23 months refining through monthly cohort masterminds and quarterly 1:1 advisor sessions. Results come fast. Mastery takes two years.
Read more →A monthly gathering of founders inside the Retrocause fellowship to review metrics, discuss progress, and hold each other accountable. The structured format makes it sharper than a peer group and more sustainable than a one-off workshop.
A metric that goes up-and-to-the-right but has little correlation with revenue, profitability, or long-term business health. Examples: total signups, website traffic, social followers. In LEVERS, vanity metrics are replaced with actionable metrics tied directly to the Revenue Formula.
