A modern, local-first GUI for real small-business double-entry bookkeeping (the gap between QuickBooks and GnuCash)
Sole proprietors and small-business owners want to own their financial data on their own machine but find GnuCash dated and hard to set up while QuickBooks is cloud-pushed, pricey, and built for businesses that already have a bookkeeper. The repeated ask is a GUI-first double-entry app that sits in the middle; one current commenter explicitly makes open source a hard requirement, while another frames the same gap around data ownership and local control.
Do not lead with another cloud ledger. The shared demand is local control, data ownership, and lower setup friction than GnuCash; open source strengthens trust for at least part of the audience, but the wedge is GnuCash's double-entry correctness wrapped in modern onboarding.

GnuCash owns correctness but not UX; the cloud incumbents own UX but not data ownership; and the emerging local/open-source GUIs are still early. A polished, approachable, local-first double-entry app for small businesses is the specific unmet middle.
