[ Overview ]

Custom Company OS

A Custom Company OS is the operating layer your business actually needed instead of stitching together fifteen SaaS tools. HR, finance, ops, projects, knowledge — one workspace, one data model, AI woven through every flow.

We start with the workflows your team runs every week and build outward. Onboarding, payroll prep, vendor approval, project status, OKR tracking, internal Q&A — each gets a purpose-built module that talks to the others natively, with AI agents handling the connective tissue humans hate.

It's the leverage of a platform engineering team, delivered as a service, sized for a company that wants to stay small and ship big.

[ What you get ]

  • Unified workspace across HR, finance, ops, projects and knowledge
  • Custom modules built around your actual processes
  • Cross-department AI workflows and agents
  • SSO, RBAC and audit log out of the box
  • Hosted and continuously evolved as a service

[ Frequently asked ]

Frequently asked

01How is this different from Notion + Zapier?

Notion is a doc store. This is a typed, transactional system of record with AI baked in — the difference between writing it down and actually running on it.

02How long until it's running our company?

We ship the first two modules in 6-8 weeks, then layer in the rest on a quarterly roadmap. You're never waiting on a big-bang launch.

03What happens to our existing tools?

We migrate the ones worth migrating and keep the ones that genuinely win. The OS is the system of record; everything else becomes optional.
