Our equity investment model is very similar to the YC/Start Fund relationship. KPCB, Mohr Davidow Ventures, and Mayo Clinic fund the companies we select with a $100,000 convertible note, at the same terms of an existing/pending seed round, or on flexible terms up to an uncapped note. We're different from YC in the sense that Rock Health itself takes no equity in the companies. We try to be extremely entrepreneur-friendly, and ultimately, the convertible note is entirely optional. For companies that don't want the note, we write non-dilutive grants up to $20,000.
In terms of whether we help our companies get funding (or not), our companies have raised more than $100M[1] from investors including Collaborative Fund, Felicis, First Round, Floodgate, Founders Collective, Founders Fund, General Catalyst, Khosla Ventures, NEA, The Social+Capital Partnership, SV Angel, True Ventures, and USVP, just to name a few (for context, our first cohort of companies finished at Rock Health in November 2011).
