NEW YORK (TheStreet) -- The IPO market is slowly warming up as recent successes such as Twilio (TWLO) - Get Report make the public market more palatable for expanding startups.

500 Startups founder Dave McClure thinks the that the companies he is helping to develop will continue the trend of being acquired rather than going public.

"I do expect [the IPO market] to pick up a little bit but still it's the case that most of our companies, probably 90% or more, exit through acquisitions and not necessarily through the IPO market," McClure said on CNBC's "Squawk Alley" Wednesday. 

McClure's organization focuses on helping to grow startups, with the majority of the businesses under his direction falling in the category of B-to-B services and fashion. He believes the current atmosphere in the private sphere means that more of those companies will be going public in the near future.

"No secret that that's probably going to be public markets now that private markets are a little stingier than they were last year," McClure added.
