// Opulent Engine — App Preview
Your AI pacer and crew chief — in one app. Trained on real race data, available from mile one to the finish line.
// What Shadow Crew Does
Trained on race reports, course profiles, and crew notes from Cocodona, Tahoe 200, Bigfoot, and Moab. Your AI pacer knows the miles ahead — the climb before the aid station, the temperature drop at 3am, and exactly when to push.
No screen required. Gesture and audio-driven interaction designed for the moment your hands are on poles and your eyes are on the trail. Ask your pacer for a split, a strategy update, or just a voice to keep you honest at mile 180.
On-device vector search and a local AI model mean your pacer and crew chief work deep in the backcountry. No signal? No problem. Shadow Crew is still with you.
Part pacer, part crew chief. Real-time strategy that adjusts to your current state — not just your plan. Fatigue, weather, cutoffs, and course profile fold into one clear call: push, ease off, or eat and keep moving.
Every course loaded with elevation, aid stations, drop bags, crew access points, and historical runner data. No generic trail app — this is built for ultra racing, start to finish.
Log your training, past races, and low points. Shadow Crew builds a model of you — not a generic runner — and uses it to decide when to push and when to let you eat and rest.
"At mile 80, your pacer isn't there yet. At mile 160, your crew is asleep at the aid station.
Shadow Crew never closes its eyes."
Opulent Engine is an independent software studio. Shadow Crew is our first app — an AI pacer and crew chief built for ultra runners tackling anything from a 50-miler to a 200-mile sufferfest.
We're building the pacer who always shows up and the crew chief who never needs sleep. Trained on real race data. Designed for real suffering. Launching for the 2026–2027 race season.
If you run Cocodona, Tahoe 200, Bigfoot, Moab 240, or any distance where the miles get dark — this is for you.
Early access registration opens later this summer. Check back soon.
