SignalRank, the Palo Alto-based technology-driven venture investment platform, today announced several key milestones, including:
· Two years of performance data for The SignalRank Index
· Launch of Version 4 (v4) of its investment selection model
· Availability of the SignalRank Index to accredited U.S. investors and overseas equivalents
· 35 Series B investments completed in 24 months
Since making its first Series B investment in May 2023, SignalRank has emerged as the world’s second most active Series B investor—trailing only Andreessen Horowitz in completed deals. SignalRank has participated in 35 financings alongside leading firms such as Sequoia Capital, General Catalyst, Lightspeed, Khosla Ventures, Accel, Founders Fund, and Kleiner Perkins.
The SignalRank Index—a first-of-its-kind venture capital index—offers qualified investors access to a diversified portfolio of high-growth AI and technology companies. Notable Index constituents include Mercor, Saronic, Chainguard, and Together AI. Shares of the Index are priced daily and are available for purchase by accredited investors and equivalent entities outside the United States. The company ultimately aims to list the Index, expanding access to retail investors and wealth managers.
Early Performance
While venture investing requires a long-term view, preliminary results are promising. As of May 2025, the SignalRank Index reports:
· 2023 cohort: 1.26x multiple on invested capital (MOIC)
· 2024 cohort: 1.2x MOIC
These early returns place the Index in the top decile of performance among comparable venture investments.
“We’re encouraged by the growth of our partner network—now nearing 300 early-stage firms,” said Rob Hodgkinson, Head of Investments at SignalRank. “The quality of both deal selection and access continues to improve, helping us deliver a compelling investment product while supporting our partners at a critical stage of company growth”
Details are available in the SignalRank Index Two-Year Briefing Report.
Launch of v4: Ensemble-Based Investment Selection Model
SignalRank also announced the release of v4, its most advanced company selection model to date. The v4 model combines heuristic and machine learning techniques in an ensemble architecture to identify high-potential Series B investments. Backtesting indicates that v4 can:
· Reject up to 87% of Series B opportunities as unlikely to perform
· Generate a projected average 6x return over five years for annual investment cohorts
Keith Teare, CEO and CTO, said: “This is the first time we’ve blended heuristics with machine learning into a true ensemble model. The backtest shows performance that exceeds that of any known Series B investor over a five-year horizon. For our partners, it’s a decision support engine; for Index investors, it signals potential returns far ahead of public market benchmarks.”
