Coming soon

We’re still building TheoryOS for founders. Leave your email and we’ll tell you when it’s ready.

For founders

Move beyond the pitch deck.

Investors don’t fund slides — they fund a theory. Your deck shows the plan. TheoryOS shows why the plan will work — so you walk into every room with the same crisp answer to “why you, why now.”

Build your first theory

The TheoryOS dashboard: four theories, each with its progress through Theory Builder and Counter View.

The shift

From a deck anyone could’ve written — to a theory only you could.

FromA 12-slide pitch that anyone in your space could have written.

ToA contrarian theory that only you could write — grounded in something you actually believe.

FromAnswering “what’s your traction?” with a hockey stick.

ToAnswering “why does this exist?” with a mechanism.

FromUpdating the deck every two weeks for fundraising.

ToEvolving a living theory as you learn — and showing investors what changed.

Presentation PrepComing soon

Your theory becomes your deck.

A deck and a script built from what you wrote, and feedback on the pitch you practice.

A finished theory on its canvas: beliefs, the core problem and its sub-problems, the actions, and the if-then theory.

Use cases

Where it fits.

01Pre-seed clarity

Crystallize your contrarian thesis before you take a single intro call. If you can’t write it sharp here, you’ll get torn apart on Sand Hill.

02Series A narrative

Build the story that holds up under partner-meeting scrutiny. Not a deck — a defensible theory of value capture.

03Team onboarding

Bring new hires into the theory, not just the roadmap. Engineers and operators do better work when they know why.

04Investor updates

Update the theory monthly. Show learning, not just metrics. Investors fund founders who evolve their thinking out loud.
