FurtherAI’s engineering account reports roughly five times as many daily merges per engineer since January, with a revert rate below 0.5%. Changes including tests rose from 15% to 91%, and AI review before human review rose from 60% to 99%. Up to one-third of low-risk changes now merge without human intervention after tests and 21 automated checks. Related coverage says investment in tooling over the summer preceded a rise in monthly customer-facing changes per engineer from 17–30 to 45 in September. This is a company case study, not an independent experiment; its conclusion is that deciding what to build and owning the outcome become the next bottlenecks.
