From tech to sales. Why teams ship with Kosuke

Cardinal

Operational risk platform

With Kosuke, the whole team hands the boring tickets to agents that work the real codebase. Each change is tested in a real browser and arrives as a pull request ready to merge, so the engineers stay on the hard engineering.

Pillar

Construction management software

With Kosuke, agents run each change in parallel sandboxes and attach a recorded end-to-end test to the pull request. Pillar ships across the whole product without adding review load.

KYC and compliance

The whole team now clears that backlog with Kosuke. Agents build each change against the real codebase, prove it in a real browser, and open a pull request the team reviews and merges with confidence.
