The engineers behind yournext product.

Build a product from the ground up or embed senior engineers directly into your existing team.

Capabilities

The technology follows the product.

We assemble the capabilities each engagement needs rather than forcing every product into the same technical package.

Web products

Customer-facing platforms, SaaS applications, marketplaces, dashboards, and internal tools built for production use.

Mobile products

Reliable iOS and Android experiences with polished interfaces, offline behavior, and maintainable shared codebases.

AI integrations

Useful AI features, retrieval systems, agent workflows, search, automation, and data-assisted product experiences.

Platform engineering

APIs, cloud infrastructure, CI/CD, observability, performance, security, and production reliability.

Products we put into the world.

Built by engineers.

Koffi started because I was tired of watching good products die in handoffs — between agencies who disappeared after launch, and contractors who never really joined the team. I wanted to build the studio I always wished I could hire: senior engineers who show up, stay accountable, and ship like it's their own company. That's still the only thing we do.

Koffi felt like our own team from day one. They shipped what two prior agencies couldn't.

Questions before we build?

A few things teams usually want to know before working with Koffi.

Yes. Koffi can own product definition, design, architecture, engineering, testing, infrastructure, deployment, and iteration. You provide the business context and decisions; we run the product-building operation.

Yes. Koffi engineers work inside your existing backlog, repository, communication tools, ceremonies, and engineering standards. They contribute as part of the team rather than operating through a separate outsourced workflow.

Not exactly. Koffi can add engineering capacity, but the engagement remains delivery-oriented. Our engineers participate in planning, architecture, code reviews, product decisions, and production ownership—not only assigned tickets.

After a short technical and product-scoping process, we agree on the engagement, team, start date, and first meaningful milestone. The goal is a focused, low-friction start without a long traditional hiring cycle.

We choose technology based on the product, constraints, and existing systems. Our work can include web and mobile products, APIs, AI integrations, cloud infrastructure, CI/CD, observability, performance, and production reliability.

End-to-end product engagements can be structured around a defined scope, milestones, or a dedicated delivery team. Embedded engineering is typically based on recurring team capacity. Final pricing depends on the scope, team composition, and expected duration.

We maintain meaningful working overlap for planning, reviews, and direct collaboration. Depending on the client’s location, development can also continue after their local workday ends, allowing the roadmap to keep moving between shared working sessions.
