Charles River Ventures, an investor in consumer and enterprise-focused startups, has raised $393 million for its 16th fund.

The company disclosed the news in a filing today with the U.S. Securities and Exchange Commission.

CRV, as it’s commonly known, focuses on Series A deals, with “occasional” investments in seed or Series B rounds, according to its website. That stance distinguishes it a bit from other firms that fund startups’ first few years of life.

Several other firms that come in on Series A rounds — Accel Partners, Andreessen Horowitz, Lightspeed Venture Partners, and True Ventures — have also raised new funds as of late.

The firm did not immediately respond to VentureBeat’s request for comment.

Previous investments include Twitter, Yammer, and Zendesk.

More recent portfolio companies include CloudGenix, Cotap, the FlatIron School, and Light.

It’s also an investor in IPO-bound Dropbox.

Izhar Armony, Jon Auerbach, Saar Gur, Devdutt Yellurkar, and George Zachary are listed in the filing.

Their new fund eclipses the previous one, which had $375 million.

The firm started in 1970 and has offices in Cambridge, Mass., and Menlo Park, Calif.
