JAM Fund, the venture capital firm launched by former Tinder chief marketing officer Justin Mateen, secured nearly a quarter of a billion dollars over the summer for a new fund.

A prolific angel investor, Mateen told Business Insider earlier this year he had a preference for founders who have a "chip on their shoulder."

Mateen, who co-founded the dating app that brought the world "swipe right" and countless unwelcome sexual solicitations, locked down his first investment for the recent fund on July 16. Since then he's raised at least $247.5 million from 15 undisclosed limited partners, a recent regulatory filing reveals.

The offering described in the U.S. Securities and Exchange Commission filing suggests that JAM Fund may raise yet more capital for its second fund. Under his principal place of business, the disclosure lists the Bel Air mansion that Mateen bought from "Full House" star Lori Loughlin and designer Mossimo Giannulli, after the couple became a key focal point in the college admissions scandal.

Mateen did not respond to a request for comment on his plans for the fund.

In addition to his personal deals, Mateen's firm has made 36 investments since August 2018, per CrunchBase, counting at least five startups this past summer. Recent deals include funding for Menlo Park-based restaurant delivery services company Owner.com and Brazil-based Kovi, which rents cars to people who drive for ride apps.

The former CMO was suspended from Tinder in 2014 after co-founder Whitney Wolfe Herd filed a sexual harassment and discrimination lawsuit against the company, describing Mateen as "verbally controlling and abusive." The suit was settled for "just over $1 million," without admission of wrongdoing, per multiple reports. Mateen was fired from the dating app company that year, a Tinder spokesperson told dot.LA. After this story was published, a spokesperson for Mateen described the nature of his departure differently. "Justin resigned; he was not fired," the spokesperson said. Wolfe went on to create Bumble.

JAM Fund frequently invests in early-stage startups outside the U.S., such as Venezuela-based food delivery app Yummy and Kenya-based restaurant inventory app Kibanda TopUp.

In Los Angeles, Mateen backed creator economy startup Voices as well as shopping subscription company FabFitFun.

Correction: This story has been updated to reflect that Whitney Wolfe Herd sued Tinder, not Mateen.

🚀 Inversion Secures $44 Million to Pioneer On-Demand Delivery from Space

🚀 Inversion Secures $44 Million to Pioneer On-Demand Delivery from Space

🔦 Spotlight

Happy Friday, LA!

This week, Southern California's thriving space tech scene celebrated another milestone as Inversion, an El Segundo-based startup, announced a $44 million Series A funding round. The investment, co-led by Spark Capital and Adjacent, with participation from Kindred Ventures, Lockheed Martin Ventures and Y Combinator, underscores the growing appetite for innovative solutions in aerospace, logistics, and beyond. To date, they’ve raised $54 million, including a $10 million seed round in 2021. In September, they also secured a $71 million STRATFI agreement with the Space Force’s SpaceWERX to develop reentry vehicles for military applications, funded through a mix of government and private investment.

Image Source: Inversion

Inversion is pioneering a new frontier: reusable vehicles capable of rapidly returning payloads from orbit to Earth. Their "Earth Return Capsules" are designed to deliver within as little as an hour, enabling everything from rapid-turnaround experiments in microgravity to the delivery of critical medical supplies across the globe.

Building on this vision, a key focus for Inversion, as noted by SpaceNews, is the development of Arc, a reentry vehicle designed to provide "precision delivery on-demand" from space to Earth. With its first flight planned for 2026, the company is using the Series A funding to move Arc through its full product cycle, including design and development. This funding will also support Inversion's growth from its current 25 employees to a team of around 70, as well as their move into a new facility. Co-founder and CEO Justin Fiaschetti emphasized that the funding is sufficient to bring Arc through its inaugural flight.

Adding to the excitement, Inversion recently achieved a critical regulatory milestone in October by receiving a re-entry license from the Federal Aviation Administration (FAA). This license is a pivotal step in their journey, allowing the company to safely and legally return payloads from orbit to Earth. It positions Inversion among a select group of companies capable of operating in this emerging sector and demonstrates their readiness to bring the concept of space-based logistics into reality.

This isn’t just a win for Inversion—it’s a win for the Los Angeles aerospace ecosystem, which continues to attract top-tier talent and funding. With giants like SpaceX and Relativity Space already calling the region home, Inversion is further cementing LA’s status as the nation’s space tech hub.

As Southern California continues to lead the way in space innovation, Inversion is one to watch. Their vision for merging cutting-edge aerospace technology with real-world logistics solutions may not just change how we view space—it might transform how we interact with it.

Stay tuned for more updates from LA’s tech and startup scene. For now, keep your eyes on the skies—Inversion is bringing them closer to Earth.
