Building StartupNinja: 75 Trackers and a Founders' Blueprint, Out of Frustration

๐Ÿฅท

StartupNinja started because I was personally annoyed. I was building ShareDeal, juggling investors, runway, BD compliance, and product โ€” and I kept reaching for the same dozen spreadsheets that other founders had quietly forwarded me. None of them lived together. None of them talked to each other.

So I built the tool I wished I had: a Flutter app with 75 interactive trackers and a Blueprint PDF that walks a founder through their first 12 months, end to end.

What's actually in it

  • Runway and burn modelling โ€” not "what's our cash position", but "what changes if I delay this hire by two months".
  • Cap table sanity checks โ€” dilution scenarios, ESOP carve-outs, SAFE-to-priced conversions.
  • Investor pipeline tracker โ€” the same data founders keep losing in scattered email threads.
  • Compliance checklist โ€” Bangladesh-specific, because every local founder I know has been bitten by that.
  • Hiring scorecards โ€” interview rubrics that survive your first dozen hires.

Why Flutter, why offline-first

The MVP is a single Flutter binary that ships everything offline. No accounts, no backend. Founders are paranoid about their data, and I am one of them. Building it offline-first meant I could focus on the model and the UX without fighting auth flows for two months.

The pivot to SaaS

The next phase is multi-tenant SaaS on Supabase, targeting Bangladesh's SMB and early-stage founder niche. The 12โ€“14 week MVP roadmap is straightforward: Supabase auth, row-level security per workspace, a sync engine on top of the existing local stores, and a paid tier for teams. The hard part is not technical โ€” it's resisting the urge to over-build before I have ten paying users.

The biggest thing I'd tell anyone building a tool for founders: you don't need new features. You need fewer apps. The job is consolidation, not invention.

Lessons so far

  1. Trackers are a love letter, not a feature list. Each one is a small UX promise: "I will save you the spreadsheet."
  2. The Blueprint sells the trackers. Founders don't buy a checklist; they buy the confidence that someone has thought about the order.
  3. Bangladesh-specific is a moat. Generic tools lose to anything that knows local compliance.
