The problem
Corporate events waste thousands
on uncoordinated ground transport.
Scattered arrivals
People land at different times across different terminals and airports.
No visibility
No one knows who should share a ride or who's even arriving when.
Planners become dispatchers
Event organizers spend hours coordinating rides instead of running events.
The numbers
Ground transport is a bigger line item
than most companies realize.
According to the Global Business Travel Association, global business travel spending hit $1.48 trillion in 2024. Ground transportation — taxis, rideshares, and car services — accounts for 11–12% of total trip cost, and 70.5% of those ground transport receipts are ride-hailing services like Uber and Lyft, not rental cars.
For a 100-person corporate event, that adds up fast. At an average of $103 per traveler in ground transport per trip, a single event can easily generate $10,000+ in rideshare charges — most of it one-person-per-car rides from the airport.

Side by side
Ad-hoc rides vs. SeatMax
Most companies expense rideshares after the fact with no coordination. Here's how that compares to grouping travelers automatically.
| Ad-hoc rideshares | SeatMax | |
|---|---|---|
| Vehicle utilization | 1 person per car (typical) | 3–6 per car, optimized mix of UberX & UberXL |
| Planner effort | Hours of spreadsheets & messaging | 30 seconds to create event, auto from there |
| Flight delay handling | Manual re-coordination | Automatic re-grouping in real time |
| Cost visibility | After-the-fact expense reports | Upfront Uber estimates per vehicle |
| Multi-airport support | Separate coordination per airport | All airports grouped simultaneously |

Under the hood
How the grouping algorithm works
SeatMax doesn't just sort by time — it optimizes across multiple dimensions to pack every vehicle as full as possible while keeping wait times short.
1
Partition by date and airport
Travelers are split by arrival date and airport. Multi-airport events (e.g., ORD + MDW for Chicago) are handled separately.
2
Zone by terminal
Within each airport, travelers are grouped by terminal zone. Adjacent terminals (like JFK T1/T2) share a zone so nearby arrivals can share a ride.
3
Bucket by time window
Within each zone, travelers are sorted by estimated arrival and bucketed into configurable time windows (default: 45 minutes). This keeps wait times reasonable.
4
Pack vehicles optimally
Each bucket is filled with the best mix of UberX (4 seats) and UberXL (6 seats) using a bin-packing algorithm. The optimizer picks the combination that minimizes total cost.
5
Re-group on delay
When a flight is delayed, the traveler is moved to a later time bucket and vehicles are re-optimized. No manual intervention needed.
