About 47 Signals

47 Signals is a small, independent software product studio. We design, build, and operate digital products end-to-end — combining thoughtful product design, reliable engineering, and long-term operational discipline. Our work spans consumer mobile apps and B2B SaaS platforms, with a focus on products that are built to last rather than built to flip.

About the name

The name 47 Signals is a deliberate nod to 37signals, a company whose approach to software craftsmanship, focus, and independence deeply influenced how we think about building products. The work of DHH and Jason Fried, along with books like ReWork and Remote, helped shape our perspective on what it means to create software that is calm, purposeful, and built to last — without unnecessary complexity or noise.

What we work on

Our current products include Smart Miles, an automatic mileage tracking app for drivers who need IRS-ready records, and Call Tracker, a SaaS platform for attributing and analyzing inbound phone calls from marketing campaigns.
