Financial Performance Metrics
Understanding a16z’s financial performance is critical for investors evaluating their track record. While specific metrics like IRR and TVPI are not publicly disclosed, industry benchmarks and portfolio data provide insight into their success.
Internal Rate of Return (IRR)
The IRR, which measures annualized returns, is a closely guarded metric in VC. For a16z, estimates suggest an IRR of 20-30% for top-performing funds, driven by exits like Airbnb and GitHub. “High IRR reflects a firm’s ability to select winners and time exits effectively,” says Dr. Jane Kim, a VC analyst at Stanford University. Without public data, we infer strong performance from a16z’s consistent fundraising success and high-profile exits.
Total Value to Paid-In Capital (TVPI)
TVPI, the ratio of total investment value to capital invested, is another private metric. a16z’s portfolio, with 447 exits and significant unrealized value in companies like xAI, suggests a robust TVPI. Industry averages for top VCs range from 2x to 5x, and a16z likely falls in this range for mature funds.
Distributed to Paid-In Capital (DPI)
DPI measures cash returned to LPs. While exact figures are unavailable, a16z’s exits, such as Skype ($8.5 billion to Microsoft) and GitHub ($7.5 billion), indicate strong DPI for early funds. “DPI is a key indicator of liquidity for LPs,” notes VC expert Michael Chen in a 2024 Forbes article.
