Who is Calvin Anderson

Calvin Anderson is a professional football player and a real estate investor who does not treat the two as separate lives. He was born in Philadelphia in 1996 and raised in Austin, so the room he spoke in is his hometown. He played college football at Rice, where he started 36 straight games, took All-Conference honors in Conference USA in both 2016 and 2017, and majored in mathematical economics. He then spent a graduate season at the University of Texas, choosing it over Michigan, Oklahoma and Auburn.

He went undrafted in 2019 and built a seven-year NFL career anyway, which is the hard way and the only way available to him at the time.

On the field

The route went Patriots, then the Jets practice squad, then Denver, where he made his first start in week ten of 2020 and eventually signed a two-year extension worth $2.5 million in 2022. Then back to New England, then Pittsburgh in September 2024, where a knee injury put him on injured reserve in December 2025. The Steelers released him in March 2026 and he has not signed with another club since, so as of this writing he is a free agent rather than a rostered player.

Along the way he served as a player representative for the NFL Players Association, the players' union, which is its own lesson in reading a room and negotiating on behalf of people other than yourself. He is also, unusually for a 300-pound lineman, a Rubik's Cube brand ambassador who can solve one blindfolded.

Football is not intrinsically important unless I use it as a tool to have a positive impact on somebody else.

What he is building

In 2023 Anderson co-founded JB5 Investments with his wife, Sheree Lanihun-Anderson. He is the numbers side of it, bringing the financial modeling and data work his Rice degree prepared him for. She is not a silent partner in any sense: she is a Cambridge-trained real estate lawyer who spent four years as an acquisitions manager at Akelius Residential in London, and she runs strategy and development. Her father leads the firm's operations on the ground in Nigeria.

They met on a dating app in 2020 and married in 2022, skipping a large wedding and putting the money into the Lanihun-Anderson Foundation, which works on poverty and financial literacy in Nigeria. The firm now works across four countries, with its Nigerian operation based in Lagos, its first development there called Ascended Living, and its focus on middle-class housing. The details they talk about are the unglamorous ones that decide whether a building is actually good to live in: water filtration, non-slip stair tiles, fixtures that survive the climate. Their stated intent is to hold rather than flip.

We believe Nigeria is the next frontier. It has untapped potential, and we are proud to invest.

The illness that changed it

In July 2023, on a philanthropic trip to Nigeria with his wife, Anderson contracted falciparum malaria. It nearly killed him. He ran a fever of 104.5, went into kidney failure, developed an enlarged spleen and lost more than thirty pounds. Doctors put his odds of survival at roughly even. He missed all but five games that season.

He has said the recovery was worse than any football injury because there was no protocol for it.

It's like if you're Superman, you feel like your superpowers are taken away.

Beyond football

A Boston Globe piece about his recovery reached the UN Foundation, and in May 2024 he became an ambassador for United to Beat Malaria. He has not treated it as a logo on a jersey. He wrote an op-ed in USA Today in March 2025 and went to Capitol Hill in August 2025 to argue against cuts to the President's Malaria Initiative. In 2026 he received the Clio Health Impact Award for the work.

He is clear about why the advocacy carries weight coming from him specifically, and it is not the football.

My story makes a lot of sense because I'm not just an athlete that's just championing a cause. I actually had malaria and we are present in Nigeria where most of the malaria cases are.

It is the same pattern as the rest of his story. Take the hit, then build something with it.
