The first 90 days decide whether a security startup has a product or just a deck. As the PM, my job is to make sure we build the right thing first — not the most exciting thing, the most load-bearing one.
Three sprints, three goals
- Sprint one: find the spine. We identify the single workflow the whole product hangs on and design it end to end.
- Sprint two: make it real. The spine becomes a clickable, data-shaped prototype the founders can put in front of design partners.
- Sprint three: pressure-test. We break it on purpose — empty states, edge cases, the unglamorous reality — and harden what survives.
A prototype that only works in the demo is a liability. By day 90 we want one that holds up when a real user pokes at it.
What we deliberately do not do is chase breadth. Ninety days of focus on the load-bearing workflow beats a year of half-built modules every time.
