So Minerva isn't actually a university (they don't have the power to award degrees), so instead their degree is awarded by the Keck Graduate Institute of Applied Life Sciences, which is a private university that Minerva have a paid partnership with (hence "Minerva Schools at KGI"). But yes, they do actually get a degree. Whether or not it's recognisable is a different question (the Keck Graduate Institute is ranked 2032nd in the world according to 4icu, which, to give a UK comparison, ranks below Falmouth University at 2005th).
Edit: even Wikipedia describes Minerva Schools at KGI as a "university program" rather than a university/college.
