Short Answer:  Nope. That would suggest he's against business.

First Answer: During the CBS This Morning interview where Bernie Sanders announced his 2020 presidency, co-host John asked the presidential candidate "what's your opinion on capitalism?"

"I think what we see in this country and around the world there's a lot of great entrepreneurs who have come up with some great ideas and some great products. But what I think is happening is some of these folks...we have a system that allows these people [the top 0.1%] to accumulate huge amounts of income and wealth. When I talk about democratic socialism, I'm not talking about the government taking over the local grocery store or anything else like that."

Better Answer: Check his track record.

In 2008, Sanders drafted a prizes-not-patents bill that would allow drug companies to be rewarded for innovation with an upfront cash prize of 1 million.

From Slate Magazine January 2008:

"What if the reward for innovation were an upfront cash prize, independent of the market for the invention? This is what Sen. Bernie Sanders, I-Vt., is proposing in a bill that's escaped the notice of the heavyweights fighting over the patent-reform legislation. Sanders' bill would eliminate drug monopolies; instead, all medical developments would automatically enter the public domain, so more companies could manufacture each new drug. With increased manufacturing competition and zero licensing fees, drug prices should, theoretically, plummet."

In 2010, Sanders helps pass the Small Business Jobs Act. A bill that provides low interest loans to small businesses and community banks.

In that same year the bill passed, Sanders said, “In the midst of the very difficult recession that we’re in, helping small businesses receive affordable credit is imperative.  Small business creates most of the new jobs in this country and it’s important that we do everything we can to help them."

From Senator Bernie Sanders Government Page:

The new Small Business Jobs program boosts commercial lending with a $30 billion lending fund for health Main Street banks to boost capital access to small firms wanting to grow their businesses and hire new workers; it provides tax relief to small businesses in Vermont and nationwide; and it modernizes the application for SBA’s lending programs.
