About us
We make performance technology accessible to all of fitness — from the gym to the athlete.
How it started
Vektor Fitness was born in April 2024, in Pouso Alegre (MG), founded by Rafael Bernardes and Jorge Fernando. Their dream was already what is now Vektor Pulse: every member's heart rate live on the gym TV. At the time, it wasn't yet possible to build it. So the company started with Vektor Speed, smart timing for sprints and agility.
Growing by reinvesting
Speed grew the company, and what it earned was reinvested until Vektor Pulse finally became real. Along the way came Vektor Jump and the other technologies that make up the platform today — Pulse Personal and Performance — for training monitoring, assessment and programming.

Until 2026 the company was called JF Tecnologia Fitness. In May 2026 the brand became Vektor Fitness: renewed, with a name that stands for the whole platform rather than a single product.
What we believe
Our purpose is to democratize technology for fitness: bringing real-time data, gamification and performance tools to gyms, training centers, studios and personal trainers of every size. We want to grow together with our partners, always improving our products and the performance of the members and athletes who believe in Vektor.
Where we are
We are based in Santa Rita do Sapucaí (MG), Brazil's Electronics Valley, and are currently a startup incubated at Inatel Startups, the Inatel incubator. Our products are developed and assembled in Brazil, right here in the Electronics Valley. All infrastructure is hosted in Brazil and complies with the LGPD, Brazil's data protection law.
