About Kai
Professional shared-ownership software, engineered by a team with 20+ years of platform experience.
Engineered by a team that co-owns the same kinds of assets you do, built to the standard we hold our own infrastructure to.
Built by Seny Labs
Kai is developed by Seny Labs, a software studio led by engineers with 20+ years of experience architecting production platforms. When our team started co-owning aircraft and vehicles, it was clear that shared-ownership groups deserved the same quality of software enterprises rely on every day.
Kai brings bookings, expenses, maintenance, documents, and member communication into one reliable system — built to Seny Labs' engineering standards, and trusted to run our own groups.
