WHAT WE BELIEVE

Platform engineering is not a luxury. It is a prerequisite.

Open Source First

We open-source our stack catalog and game-server platform (Minami). Engineering buyers trust what they can read. Clients can leave.

Transparency Over Lock-in

Operational dependency is fine. Technical lock-in is not. Every engagement has a clear handover story so clients can self-operate when ready.

Operational Excellence

We run what we build. Day 1 deploy, Day 2 operate, Day 3 evolve. Retainer-based, not project-based.

Cloud-Agnostic by Design

Kubernetes, Crossplane, FluxCD. No cloud-specific magic. Portability is a feature, not an afterthought.

7KGroup was founded in Tokyo by infrastructure engineers who believed that platform engineering should be accessible to companies of all sizes — not just those with $3M/year to spend on a dedicated platform team.

We work with Series A–C companies with 20–150 engineers who need a working platform now, not in 12 months. Our stacks are open-source. Our process is transparent. Our goal is to make you self-sufficient.

COMING SOON

We're collecting stories from the teams we work with.
Check back soon for real testimonials and case studies.

OPEN SOURCE

We ship in public.

Our core stacks and tools are open-source. You can read the code, fork the repos, and deploy them yourself. We sell operation, not access.
