There is a roughly 24-month window to wedge local AI-native software into legacy verticals

Greg Isenberg argues that industries like home health documentation, field restoration reporting, and professional services outbound review are still running on antiquated software — in some cases tools from the early 2000s. That creates a narrow but real window, which he estimates at around 24 months, to build local AI-native products and establish a foothold before larger players catch up or the market consolidates. The strategy across all of these ideas is the same: find a specific, painful workflow, build a tight wedge product around it, and expand from there once you have traction.
