Who We Are
About
We started building apps. Then we started building the platform to ship them.
Our Story
From building apps to
building the stack.
Kobumura started with a simple problem: shipping mobile apps is harder than building them. We were building consumer apps and spending more time wrestling with deployments, monitoring dashboards, and subscription infrastructure than writing features.
So we started building tools. A CI/CD pipeline that actually works for mobile. A monitoring dashboard that puts revenue, ads, and engagement in one place. A white-label template so the next app starts at 60% instead of zero.
Now those tools are becoming a platform — the App Stack. AI democratized development. We're democratizing delivery — the infrastructure, pipelines, and monitoring that turn code into shipped products — and shipped products into businesses.
How We Work
Tech Philosophy
Ship first, perfect later
Technical debt isn't the enemy — invisible technical debt is. We ship fast, document the shortcuts, and fix them systematically. Every shortcut gets a ticket.
Boring tech, interesting products
React Native, Node.js, PHP, Express — proven stacks that let us focus on the product, not the toolchain. We pick technologies that have good documentation and large communities.
AI-assisted, human-directed
We use AI tools extensively in development. But AI is the accelerant, not the architect. Every decision, every PR, every deploy has a human behind it who understands the why.
Test the behavior, not the code
Comprehensive testing at every level — unit, component, integration, E2E. We test what the user sees and does, not internal implementation details. Every component gets a test file.

The Team
Small team. Big ambition.
We're a small, focused team with offices in Maryland, Pennsylvania, and Vermont. We believe small teams with good tooling can outship much larger organizations. Every line of code gets attention because there's nowhere to hide.
