The intelligence layer for the post-SaaS era

AI collapsed the cost of building software from months to hours. vendor.rip tells you what to replace, how to build it, and what others have already shipped.

{ FLEET LEARNING }

Every rip makes the next
one smarter.

Every Tesla on the road trains Autopilot for all the others. Every rip sharpens the scores for the next team. Anonymized metadata only — never your code, never your data.

This is what 47 rips taught us about Looker.
Imagine what 10,000 will teach us about yours.

Teams share anonymized build metadata — stack, timeline, gotchas. Never code, never data. The more teams share, the smarter the scores get.
