CockroachDB, a 1.5-year-old, New York-based open-database company that aims to keep the applications of its enterprise customers up and running, even when their data centers and cloud infrastructure suddenly go offline, has raised $20 million in Series A1 funding. The capital comes from Index Ventures and earlier investors Benchmark and GV (formerly Google Ventures).

The new money comes less than a year after CockroachDB announced $6.25 million in Series A funding led by Benchmark’s Peter Fenton, who is known for many of his high-profile, and largely successful, enterprise bets, including Zendesk, Hortonworks, and New Relic.

Along with GV, other participants in that earlier round included Sequoia Capital, FirstMark Capital, and numerous tech executives, including Hortonworks CEO Rob Bearden and Cloudera cofounder Jeff Hammerbacher.

Cockroach was founded by former Google software engineers Spencer Kimball, Peter Mattis, and Ben Darnell. Kimball, who is CEO, and Mattis, who is Cockroach’s VP of engineering, previously cofounded a photo-sharing app called Viewfinder that sold to Square in late 2013 for undisclosed terms. The company, which employed less than a dozen people at the time, had raised an undisclosed amount of seed funding.
