Our Story
Tractivvity started as a project between a father and son. With college on the horizon, it was a chance to share something real — the full arc of building software, from first idea to the details that make it work. Gran Turismo 7 was the obvious choice. We both love the game, and the shared obsession kept us showing up.
We’re from Indianapolis. Racing isn’t in our family, but it’s in the pulse of the city — you grow up with the month of May, with strangers who can tell you exactly where they were for a given finish, with a kind of reverence for the craft that seeps in whether you asked for it or not. That’s the air we breathe. We know the GT7 community feels the same way about this game — the obsession, the respect, the love of the craft — and we hope that shows in the time and care we've put into Tractivvity.
Somewhere along the way, it stopped being a learning exercise. The more we built, the more we realized we had something worth sharing with the broader GT7 community.
We’re racers. Not the fastest on the grid, not chasing world records — but we love the craft, and we love the community around this game. We built Tractivvity for drivers like us: curious, a little obsessive, and looking for tools that make the time on track more meaningful.
Mission
Bring serious telemetry analysis to the masses — not just the fastest few — and build community features around it that give every driver a reason to come back. Whether you’re shaving tenths off a hot lap or just curious why turn 3 always bites you, Tractivvity is for you.
Acknowledgements
We stand on the shoulders of the people who paved the way for GT7 telemetry — the reverse engineers who cracked the UDP protocol, the open-source developers who wrote the first dashboards, and the community members who kept it alive. This project wouldn’t exist without their work, and we’re grateful to everyone who contributed to the craft before us.
