Poseidon Asset Management, a marijuana-focused fund, is raising $75 million to go after Series A or later investments in marijuana companies, said Morgan Paxhia, a managing partner. The fund will be divided across four verticals in the marijuana industry, though Paxhia said he's particularly bullish on ancillary tech. Poseidon has a solid track record: The fund got into buzzy vape startups Pax and Juul early on, and sold off their position in Aphria, a Canadian cannabis producer, before it was targeted by short-sellers. A leading marijuana-focused firm run by a brother-and-sister team is raising a new fund.
