It's tough to say whether the private market for tech companies is in bubble territory, but lofty late-stage funding in Silicon Valley could benefit from public market discipline, the managing director at Lerer Hippeau Ventures said Thursday.
When it comes to late-stage funding rounds, it's hard to know whether a company like transportation network Uber is worth $25 billion or $45 billion, Ben Lerer argued, when investors don't have the public markets to regulate the pricing.
Redpoint Ventures partner Geoff Yang was more definitive—saying he believes the late-stage private market had entered bubble territory.
"There's a lot of money on the West Coast in particular going into these late stage businesses," Lerer told CNBC's "Squawk Box" in an interview. "Uber is an amazing company. These businesses that are raising in the billions of dollars of valuations are amazing businesses, but how amazing, I don't know?"
Lerer Hippeau focuses on early-stage funding in the New York City area. The firm's investments include media website Buzzfeed, 3-D printer manufacturer Makerbot Industries, and eyeglasses Internet retailer Warby Parker.
"When the market's hot, the pre-money valuation on the deals we do might be $6 million versus $5 million, so there's smaller movement in the market that we're investing in," Lerer said.
