About Approxima
Summary
Approxima builds autonomous AI agents that handle software maintenance work: scoping tasks, writing code, validating fixes in sandbox environments, and merging changes to production. It targets engineering teams who currently spend developer time on routine bug fixes, maintenance, and incremental updates rather than new product work. The agents run end-to-end on each pull request, replacing the manual triage and review cycle that slows teams down.
Go-to-market
Approxima sells to B2B and enterprise software teams through a sales-led motion, with prospects booking a demo to get started.
From the Y Combinator listing
Your software should build itself.
Human-assisted development should be for novel ideation, not routine maintenance, bug fixes or incremental updates. Approxima is bringing you that future with agents that can scope work, code, validate their fixes end-to-end in sandbox environments and merge to production.
