SignalRank

SignalRank selects top-decile venture-backed Series B companies using proprietary heuristic and AI models trained on over 60 million data points from more than one million fundraising rounds. It then purchases the pro-rata rights from early-stage seed investors in the selected rounds. This provides access to qualifying Series B allocations without the firm needing to lead rounds or build traditional GP relationships.

SignalRank exclusively targets Series B rounds of venture-backed companies. The firm's models score all funding rounds through Series B to identify the top 10% of early-stage private companies with the highest probability of outlier returns.

SignalRank acquires direct pro-rata allocations in qualifying Series B rounds by purchasing those rights from seed investors, rather than making primary fund commitments or leading rounds. It does not publicly disclose its fund structure or vehicle specifics.

According to the firm's website, backtested performance for 2012–2020 vintages shows an average 6.8x multiple on invested capital within five years of the initial investment. This compares to a 3.5x market benchmark for all Series B rounds over the same period. The backtest also shows a 31% probability of investing in a future unicorn at Series B, versus a 13% market average.

SignalRank does not publicly disclose its assets under management, team size, or the names of its principals. Its website focuses entirely on its quantitative model, portfolio construction approach, and backtested performance data.

SignalRank describes a long-horizon compounding approach with target liquidity through eventual sales of listed shares as portfolio companies go public. It does not emphasize secondary sales as a primary exit route.

Per the firm's backtested data, 70% of its selected Series B companies raised a subsequent Series C, compared with 46% for all Series Bs market-wide. The model's rejection accuracy — its ability to identify a Series B that will not meet SignalRank's success threshold — stands at 86%.
