Every month, Sai rebuilds your 10-slide pitch deck from the same numbers your team already tracks, updates the traction and runway slides, and flags every claim the data no longer supports — so the deck is ready the day an investor asks for it.
Most founders do not have a pitch deck problem. They have a stale pitch deck problem. The deck was built for the last round, and in the months since, traction has doubled, pricing has changed, two people have joined, and one competitor has pivoted. None of that reaches the slides until an investor asks for "the latest deck" — and then it becomes a weekend of rebuilding under pressure, which is exactly when numbers get copied wrong.
Once a month, Sai rebuilds your deck on a standard 10-slide seed structure. The slides that are pure numbers — traction, business model, team, and the ask — are updated automatically from the sources your team already maintains. The slides that are judgment — problem, solution, why now, market, competition — keep your wording, but are checked against current evidence and flagged when a claim no longer holds. A change log at the top shows what moved since last month.
A template tells you what each slide should contain. The more useful question between rounds is what quietly stops being true.
A deck that rewrites its own story every month would be worse than a stale one. The founder's framing of the problem is the argument, and it should change only when the founder decides it should. So Sai draws a hard line: numbers are refreshed from source, and every figure links back to where it came from; narrative slides are never rewritten, only marked "Needs review" with a one-line reason — a competitor raised, a market assumption no longer matches who is actually buying. The founder decides what to do with the flag.
Each monthly deck keeps its own link, and the change log compares it with the previous month. Over time that history becomes useful on its own: you can see how long a slide has been flagged without being fixed, and investors who saw an earlier version can be sent a deck that shows real progress rather than a new coat of paint. If a source is missing, the number is left blank and the missing input is named, rather than carried forward from last month as if it were current.
This deck pulls from the rest of the founder toolkit. Traction comes from the same numbers as the weekly executive briefing deck. The ask slide's runway figure comes from the monthly cash runway calculator, and the business model slide can cite the monthly SaaS metrics dashboard. The competition slide is checked against the monthly market landscape map. For the classic slide order this structure follows, see Y Combinator's guide to seed fundraising.
