Oxeia Biopharmaceuticals raises over $1.2M in crowdfunding for concussion therapy

Oxeia Biopharmaceuticals has oversubscribed its first Regulation Crowdfunding campaign, raising over $1.2 million before its scheduled close. The Boston-based clinical-stage biotech has extended the round to accommodate additional investors. The company is developing OXE103, a ghrelin therapy for persistent concussion symptoms. In a Phase 2a trial at the University of Kansas Medical Center, the treatment demonstrated an 85% responder rate compared to 33% for standard care alone. Between 1.4 and 4.2 million Americans develop persistent concussion symptoms annually, with no FDA-approved treatments currently available. Through a licensing agreement with Daiichi Sankyo, Oxeia acquired extensive clinical development data, including nine completed studies and safety trials involving over 300 patients. NFL players Alex Smith and Richard Sherman serve as director and advisor respectively.

StartEngine acquires vinovest to broaden access to alternative assets. Fine wine and whisky now join startups and pre-IPO opportunities on a growing investment platform. March 24, 2026 14:28 ET | Source: Vinovest West Hollywood, CA, March 24, 2026 (GLOBE NEWSWIRE) - StartEngine, a leading private investing platform, is pleased to announce the acquisition of Vinovest, a leading platform for fine wine and whisky investment. The deal further expands access to alternative assets for a growing network of more than 2.1 million, with $1.5 billion invested in total to date.[1] Vinovest is acquired by StartEngine. Total achieved when combined with StartEngine's asset acquisition of competitor platform SeedInvest. See footnote 1 for more details. Since 2014, StartEngine has connected users with a wide array of private market opportunities. That includes startups as well as pre-IPO opportunities, offering exposure to well-known private companies like Anthropic, Stripe, xAI, and more.[2] "Vinovest opens the door to a new category of alternative assets for our investors, while staying true to our mission of expanding access to private markets," said Howard Marks, Co-Founder and CEO of StartEngine. "What stood out to me is how similar our communities are: investors looking for uncorrelated investments for their portfolios. Pre-IPO funds and wines are uncorrelated assets. Founded in 2019, Vinovest has built a community of 200,00 users.[1] The company has been entrusted with securing approximately $140 million worth of wine and whisky for its clients. Vinovest uses data and industry expertise to source, authenticate, and store high-quality bottles in bonded warehouses. The platform handles portfolio management, insurance, and logistics, while investors can track performance over time and choose to sell or take delivery of their holdings. Vinovest has also developed relationships in the wine industry, allowing top wineries from around the world to reach the next generation of collectors and investors in the company's network. Vinovest will continue to operate as a wholly owned subsidiary under its existing brand. "When we started Vinovest, we believed that fine wine and whisky deserved a seat at the table alongside pre-IPO funds," said Brent Akamine, Co-Founder and CEO of Vinovest. "Joining StartEngine means we can now bring that vision to more investors." The acquisition reflects what StartEngine believes is growing interest from retail investors in alternative assets. From private companies to fine wine and whisky, alternative assets have historically delivered diversification and uncorrelated returns. The broader alternative investment market is projected to reach nearly $60 trillion by 2033.[3] Platforms like StartEngine and Vinovest are making them accessible to individual investors.
