The funds will be used to fund growth through hiring, international expansion and acquisitions. “We’re generating revenue at an annualized run rate of $60 million, up more than 80% over last year, and we still see a huge market opportunity ahead of us,” said HubSpot CEO and co-founder Brian Halligan. Dharmesh Shah, HubSpot CTO and co-founder, noted that the company’s customers have generated more than 56 million leads since HubSpot was founded.
