Marcin Kleczynski didn’t want the money.
It was February 2013, and Mr. Kleczynski, the chief executive of an antivirus start-up called Malwarebytes, had received a cold call from a venture capitalist hoping to discuss a possible investment. But Malwarebytes, which started in 2008, was already making enough profit to sustain itself.
Now, a little more than a year later, Mr. Kleczynski has accepted the check. Malwarebytes announced on Thursday a $30 million investment from Highland Capital Partners, the same firm that tried to get in the door in 2013. It is the first outside capital Malwarebytes has raised.
