Corporate context
Ownership and Leadership Context
Dave Kaemmer
Co-Founder / Chief Executive Officer, as identified in first-party material.

Co-Founder, as identified in first-party material.
iRacing publicly identifies John Henry as:
- Principal owner of the Boston Red Sox
- Principal / associated owner of Liverpool Football Club through Fenway Sports Group
- Associated with NASCAR team ownership through Roush Fenway Keselowski Racing and predecessor Roush Fenway Racing
iRacing is described here as co-founded by Dave Kaemmer and John Henry. The public record identified to date does not establish that Fenway Sports Group owns iRacing, and no percentage equity ownership is stated because no formal corporate record supporting a figure has been identified.
