The Boston tech scene hasn’t had a big IPO since Kayak last summer. So who’s next? A new entrant in the race might be Extreme Reach, an online video-advertising firm based in Needham, which has just raised $50 million in growth financing. The company has 10 offices across North America and is on pace for $100 million in annual revenue. So add them to an IPO watch list that includes (locally) HubSpot, Jumptap, Acquia, and Wayfair.
