VCDelta provides simple tools for generating machine-readable VC investment data.
Investors and entrepreneurs both want to share information about investment activity - it helps entrepreneurs find active investors, which benefits both parties.
That said, there's no standardized mechanism for sharing this information, and all sources of data are incomplete - which means tools for fundraising entrepreneurs are both difficult to build and often inaccurate. Databases like Crunchbase are often out of date. The Twitter bot @VCDelta scrapes venture capital websites and publicizes portfolio changes, but the tool is fragile and not all sites can be effectively scraped.
