Real Estate Investor

Justin Mateen has worked to develop a real estate investment portfolio. This includes investments in the Palihotel in Westwood and the Triangle in Costa Mesa.

Justin Mateen was a childhood friend of Sean Rad, both coming from similar families in the Los Angeles area. And when Sean Rad began working on Matchbox in 2012, which later became Tinder, as part of startup incubator Hatch Labs, they moved to work out of Justin Mateen's personal office. Justin Mateen was brought onto the Tinder project in 2012 as a temporary contractor to lead launch marketing for two months. He later became the CMO and an official co-founder of Tinder as the app quickly grew. Tinder was founded as a joint venture with Interactive Corp (IAC).

In 2014, Justin Mateen resigned from Tinder during allegation of sexual harassment which led to his suspension by IAC. Justin Mateen was cleared of any wrongdoing and a settlement against him, Sean Rad, and Tinder was settled out of court.

Lawsuit against IAC

Sean Rad and Justin Mateen filed a $2 billion dollar lawsuit against IAC. Their lawsuit alleges that IAC undervalued their options when they bought out Sean Rad and Justin Mateen. IAC bought them out at a valuation of $3 billion, but Rad and Mateen allege the true valuation of their option was $5 billion.
