SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Safe Data Writes for ERPs Without an API

Checked, queued writes into API-less ERPs for mid-market IT teams.

Staff at firms on old ERPs with no API retype data between screens, Excel and portals. This tool queues each write, reads it back and logs it.

In their words

we are doing hundreds of hours of manual work exporting data from one system, cleaning it, and uploading it into NetSuite with journal entries each month

r/Accounting on Reddit

The biggest limitation is the write api, if you are looking to automate vendor invoice entry or customer deposit entry it is next to impossible

r/deltek on Reddit

Standard B1 data entry gets painful at scale... slow and error-prone when done screen-by-screen, and mistakes in master data ripple downstream.

The pain point it solves: Stuck on Legacy Systems

Teams are stuck maintaining fragile, undocumented legacy systems that are too critical or costly to replace, blocking modernization and innovation.

Why those fall short

  • legacy architecture complex and convoluted, hard to build on
  • no LTO-3 hardware since 2015, tapes unreadable
  • no data migration path, vendor support gone, steep learning curve
  • Legacy systems not automation friendly; scripts break on small changes; data wrong or undocumented
  • internal docs point to departed engineers
