Three months after receiving a $32 million Series D financing round, led by Sequoia Capital, Google Ventures, and, inbound marketing software company HubSpot has announced its acquisition of Performable. Financial terms of the deal have not been disclosed.

Performable is a web-based platform that offers companies a unified view of customers across e-mail, web, social media, mobile channels and third-party apps. Performable tools track and leverage real user behavior over the course of time, not just anonymous pageviews.

HubSpot founders said this acquisition will enable them to provide innovative marketing functionality to their 4,500 customers, including advanced landing page optimization, lead nurturing with event-triggered communication, and marketing analytics from across the Web, email, social media, and mobile channels. HubSpot customers will be able to access this enhanced functionality immediately.
