SignalRank is the first private-markets index built from preferred Series B shares, using a proprietary ensemble model trained on over 1 million fundraising rounds to systematically reject about 87% of Series B opportunities and create an index-like way to buy top private companies rather than operating as a traditional blind-pool VC fund. The fund uses a Pro Rata as a Service model, systematically buying follow-on rights from capital-constrained seed managers and making traditionally elite Series B deals accessible to accredited and eventually retail investors through index-like shares priced daily with minimums starting at $25K.
