Berk was right: “couples expenses,” “dashboards,” “reminders,” and “notes” all have hundreds of clones. The interesting bit is a narrow unbearable moment, a weird distribution wedge, or a data artifact people cannot get elsewhere.
1 · strongest product bet
Crypto transaction preflight / receipt explainer
Before a user signs, paste a wallet transaction or connect a wallet and get plain language: what approvals change, what assets can move later, worst-case spend, whether the contract is suspicious, and what the human receipt says after signing.
Why it has teeth: it sits at the panic moment before money moves, not as another portfolio dashboard. People pay for “don’t let me sign something stupid.”
MVP: Base/EVM only. Static calldata decoding + allowance warnings first; simulation later.
2 · fastest weekend prototype
Held-out decision ledger
For couples or tiny teams: record the decision, why it was made, owner, revisit date, and what would count as new evidence. When the argument returns, attach the new dispute to the frozen prior decision instead of relitigating from vibes.
The metaphor: train/test leakage for human memory. Don’t chop one emotional episode into ten examples and overfit to the latest slice.
MVP: Telegram commands: /agree, /expense, /revisit. First domain: trip/couple spending.
3 · physical artifact wedge
E-ink daily artifact generator
Not a dashboard. A once-a-day printable/paperlike page with weather, calendar pinch points, one money warning, one logistics reminder, and one optional digest.
Why not generic: the constraint is the product. It wins by saying less, refreshing once, and being physically present.
MVP: static HTML/PNG/markdown page for PaperS3/Kindle/Boox.
4
One-question charge detective
Import statement CSVs. It only interrupts for renewals, duplicates, price spikes, foreign fees, or trials ending. One question: “real, cancel, or remind?”
Why better than budgeting: people hate budgets but hate mystery charges more. Smoke alarm, not nutrition app.
5
Voice-note action compiler for messy life
Forward WhatsApp or Telegram voice notes. It extracts obligations, money mentions, dates, names, unresolved decisions, and questions waiting on someone.
Wedge: people already manage life in voice messages. This turns informal speech into obligations without becoming Notion.
My binary call
For a weekend prototype: held-out decision ledger.
For a real external SaaS bet: crypto transaction preflight.
