We build. Then we keep building.

SFDIFY builds software for clients while also developing and operating its own products. Each side makes the other better.

01 · Who we are

A product and technology studio.

We are designers and engineers who prefer shipping to pitching. Roughly half of our time goes to client work, the other half to products we own. The same people do both.

Owning products means we carry on-call, support and churn. That experience is the reason client work from SFDIFY looks and behaves the way it does.

02 · What we build

05 · Team

Small, senior, hands-on.

Designers who code, engineers who talk to customers. No account layer between you and the people doing the work.

06 · Principles

How we decide.

01

Ship the ugliest working thing first.

Real usage beats a good guess. Polish what survives.

02

Operate what you build.

Taste comes from on-call, support and churn, not from decks.

03

One system, many products.

Shared components and infrastructure let a small team run five products and a client roster.

04

Say no to most things.

Fewer features, fewer clients, fewer meetings. More of each done well.
