We build the technology layer that turns gym classes into experiences members come back for.

From JF to Vektor

We started in 2018 as JF Tecnologia Fitness, building heart-rate monitoring software for spinning and group classes. Six years and 200+ installed gyms later, our scope grew well beyond a single product. In 2026 we rebranded to Vektor Fitness to reflect a broader platform: three connected products — Pulse, Jump and Speed — each tailored to a specific kind of class.

What we believe

The next decade of the fitness industry won't be won by content libraries — it'll be won by gyms that turn each in-person class into something members talk about. Real-time data, gamification, ranking, and instructor tools are how that happens at scale. We build for operators who want to keep classes packed, members engaged, and instructors empowered.
