Former Arizona Cardinals general manager Steve Keim has surfaced in a business tie to Mohamed Coulibaly, the man recently accused of running a scam that targeted professional athletes and was later found dead in the swimming pool of his New Jersey home.
The connection came to light through a Barron’s investigation into Coulibaly’s company, Motion Ventures. According to that report, the firm persuaded athletes to put money into Shopify stores that ultimately went nowhere. Multiple former NFL players told the outlet they lost more than $1 million combined in the arrangement.
The situation took another twist this month when authorities found Coulibaly dead. ABC7 reported that investigators are still trying to determine how he died. Police have not made any arrests or filed charges tied to either the alleged scam or his death.
Documents obtained by Pro Football Talk show Motion Ventures identified Keim as its “chief operation/growth officer” in a November 2025 pitch deck. The presentation listed only two people in the company’s main leadership roles: Coulibaly and Keim. It said Keim helped steer expansion plans, assess new opportunities and support leadership decisions as the company pushed growth in the United States and overseas.
Barron’s also reported that Motion Ventures allegedly used fake sales data in business dashboards to make the online stores look more successful than they were. One example involved a reported $5,000 order from Luxembourg for 100 desktop humidifiers and 120 USB-powered cup warmers.
The person tied to the listed shipping address told Barron’s he never placed the order. “Who needs 100 humidifiers and 120 cup warmers?”
the man said.
After the report, Coulibaly pushed back on some of the claims. In comments to the New York Post, he said, “I strongly dispute a number of the factual assertions and characterizations contained in the Barron’s article and any follow-up reporting that relies upon them.”
The pitch deck also named several NFL figures as notable clients and partners, including Philadelphia Eagles defensive tackle Jalen Carter, other current and former Eagles players, Keim and Seattle Seahawks general manager John Schneider.
Keim left the Cardinals in January 2023. He later joined Rich Paul’s Klutch Sports Group in 2024 as general manager of its football division.
Authorities are still investigating the case.
