Our platform powers teams across the NBA, WNBA, and NWSL helping them boost ticket sales and deliver innovative fan experiences. We’re a remote-first team driven by core values - begin and build with trust, play like the underdog, win as a team, and do your thing. If you’re collaborative, adaptable, and eager to shape the future of live sports, Jump is the place for you.

Every cycling app will tell you how a ride felt. None of them will tell you, honestly, how well you executed it. Klizmo is built for power-meter cyclists who declare a plan — a zone target, a workout structure — and want to know afterward whether they actually held it. Not an estimate. Not a motivational nudge. A deterministic Discipline Score, calculated the same way every time, with no AI or machine learning in the scoring path. If the data isn't there, Klizmo shows "—," never a guess. We call it a referee, not a coach. Klizmo doesn't praise you, compare you to other riders, or tell you what to do next ride. It calls the ride as it happened — Overpaced Start, Late Fade, Zone Spike — the same way a race referee calls a violation: factually, without commentary. This is a deliberately narrow bet. We're not chasing the mass fitness audience or the social feed. We're building for riders and clubs who already train by the numbers and want a precise instrument for judging their own execution, not another platform trying to keep them engaged. Currently in alpha with power-meter cyclists ahead of public launch.

Avela is a platform for organizations and governments to run markets to equitably allocate resources and opportunities. The right person in the right position will change the world. Learning opportunities, field-based experiences, and consultant projects all have something in common. Currently, these opportunities are allocated through a combination of manual processes, spreadsheets, and trial-and-error - rife with implicit bias and questionable outcomes. Our mission is to more equitably and efficiently distribute opportunity. Learn more at avela.org
