Executive Summary

Many couples and small household groups still struggle with shared visibility into spending, splitting bills, and permissioned access to financial data—pain points most acute among younger, digital-first cohorts and roughly 50 million households that prefer mobile-first solutions. This lack of a simple, privacy-respecting shared ledger leads to friction in day-to-day money management and relationship stress. You could build a mobile-first, subscription-based app for couples and small groups that offers role-based permissioning, shared budgets, automatic (optional) transaction imports via bank APIs, simple expense splitting, and joint goals—designed to minimize data collection and avoid heavy advertising. A product that charges in the neighborhood of $5–10 per user per month (reflecting a $60–$120 ACV) can be viable if it delivers clear ongoing value and low churn. The market is attractive now: a $6.0B addressable market (50M digital-first households × $120 ACV) with a Market Score of 88/100 and Revenue Potential of 82/100, driven by younger users’ preference for collaborative tools and improving open-banking infrastructure. These trends reduce technical friction and increase willingness to pay for privacy-preserving subscriptions. You can differentiate through obsessive UX for small groups, explicit privacy guarantees, simple role/permission controls, and partnerships that drive organic acquisition, but be realistic—competition is medium and success requires building trust, keeping CAC low, and executing reliable bank/API integrations. If you can solve onboarding and retention economically, the unit economics and market signals suggest this is worth pursuing.
