Executive Summary

Many households and advisors still model long-term tradeoffs in ad-hoc spreadsheets that are error-prone, hard to update, and difficult to share; this creates friction for 20M addressable households and leads to suboptimal decisions. The pain is particularly acute for advisors who need transparent, auditable scenarios they can present to clients without rebuilding models each time. You could build a cloud-native scenario engine that ingests open-banking and accounting data, provides repeatable, versioned scenarios with an assumptions library, and exposes advisor-facing workflows and exportable reports. Delivered as a SaaS product (targeting roughly $300 ACV per household or client relationship), it would include APIs for integrations and simple UX for non-expert users. The market looks attractive now: a $6.0B TAM (20M × $300 ACV), a market score of 88/100 and an 80/100 revenue potential, driven by consumers moving off spreadsheets and by standardizing open banking and accounting integrations. Advisors offer a B2B2C distribution path that can accelerate adoption if product-market fit is achieved. Competitive differentiation will come from a focus on transparent, auditable modeling, repeatability, and tight data integrations rather than generic planning features; building compliance, security, and advisor workflows can form a defensible moat. Be upfront that execution risks include data quality, regulatory/security overhead, and incumbent planning tools in a medium-competition space, but the size and trends make this a promising idea to pursue if you can deliver trust and ease-of-use.
