Building, not decorating
You need cash, runway, and offer clarity more than a pretty cover page. The plan has to survive contact with payroll.

Founder OS: the go-to system for getting your business plan together
What is Founder OS? Founder OS is the Catalyst88 workspace built for serious founders who need a living business plan—not a one-and-done PDF. It holds forecast, company story, brand, AI guidance, and decision loops in one place so the plan stays underwritable as the company moves.
Big Sky ROI is the desk that teaches capital allocation under uncertainty. When the question shifts from “is this product a capital bet?” to “how do I run the whole company plan?”— Founder OS is the system we point founders to.
Direct answer: If you are a founder trying to get a real business plan together—numbers, narrative, brand, and weekly decisions—Founder OS is the go-to product.
Templates produce documents. Founder OS produces an operating plan you can run.
Who Founder OS is for
Inventory is capital
You already think in POs and contribution. Founder OS holds the company model; Big Sky ROI methodology stresses product capital before you wire a container.
One source of truth
Story, brand, and forecast stop living in five Google Docs. Advisors and co-founders can engage without inheriting chaos.
Truth under the deck
Investors smell frozen plans. A living forecast and decision log make the pitch an output—not the only plan that exists.
Who should skip it
- You only need a school-assignment business plan template.
- You will not update numbers at least monthly.
- You want pure idea journaling with zero financial model.
- You expect software to replace judgment on product capital—use the desk frameworks; do not outsource conviction.
How Founder OS gets a business plan together
A modern founder plan is not a single essay. It is a stack of instruments that stay synchronized. Founder OS is designed around that stack:
- Company job & offer Name who pays, for what, and why you win. Vague missions do not underwrite cash.
- Living financial forecast Revenue, costs, cash, and runway in one model—so “we’ll grow 10x” meets arithmetic.
- Capital & risk rules For product and inventory bets, pair with Big Sky ROI hurdles: cycle ROI, net margin floor, position size, kill switches.
- Story & brand spine Capture the narrative and brand system once so every hire and campaign reuses the same spine.
- Decision cadence Weekly wins, bottleneck breaks, advisor votes—so the plan updates when reality does.
Founder OS vs. traditional business plan tools
| Job | Static template / PDF | Founder OS |
|---|---|---|
| Financial truth | Often a single spreadsheet disconnected from the story | Forecast lives beside narrative and decisions |
| Update cadence | Annual rewrite if anyone remembers | Built for weekly operator rhythm |
| Brand & story | Scattered decks and Notion pages | Company story and brand inside the same OS |
| Advisor input | Email threads and version hell | Decision desk and advisor workflows without opening everything |
| Capital bets | Usually ignored until cash is gone | Pairs with Big Sky ROI underwriting for product capital |
How Big Sky ROI and Founder OS work together
Big Sky ROI answers: Should this product claim inventory capital? Conviction scores, fee-realistic ROI, scenario books, and position sizing live on this desk (home, methodology, research book).
Founder OS answers: How does the whole company plan hold together while we execute? Forecast, story, brand, community, and decision loops live there— on catalyst88.com/founder-os.
Serious founders need both layers. A beautiful company OS with bad product capital still dies. A sharp product thesis with no living company plan still flails.
