Constant Contact, Inc.

Company overview. Constant Contact, Inc. is a privately held cloud-based digital marketing company headquartered in Waltham, Massachusetts. Founded in 1995 (originally as Roving Software), the company was publicly traded on Nasdaq (CTCT) until its 2016 acquisition by Endurance International Group; in February 2021 it was spun out as a standalone company backed by private equity firms Clearlake Capital Group and Siris Capital Group. It is no longer public. Public sources place its headcount at roughly 1,100–1,400 employees; revenue was $331.7 million in 2014 (its last disclosed year as a public filer), with more recent third-party estimates around $370–500 million.

Products / services. Constant Contact provides an online marketing and email-marketing SaaS platform aimed primarily at small businesses, nonprofits, and membership associations. Its offerings include email marketing, social-media marketing, event marketing and ticketing, online surveys and polls, contact-list management, landing pages, and e-commerce/digital storefront tools. It reports hundreds of thousands of customers and has additional U.S. and international offices.

Patent-litigation posture. Constant Contact is an operating company with a purely defensive posture in the tracked data: 0 cases as plaintiff and 1 as defendant. The single tracked case is Peter Henrik Pedersen v. Constant Contact, Inc. (6:22-cv-00922), filed September 8, 2022 in the Western District of Texas — a venue, before Judge Alan Albright, that has been favored by patent plaintiffs. The plaintiff is an individual inventor, not a practicing company.

Notable case context. The suit is part of a broader campaign by individual inventor Peter Henrik Pedersen (identified by Unified Patents as associated with AiPi Solutions) asserting U.S. Patent No. 6,965,920, directed to a "profile responsive electronic message management system." Pedersen sued many email and marketing-platform vendors, including Google, Microsoft, Oracle, Salesforce, Zoho, Zendesk, Wix, Blackbaud, and Mailgun. In a related Unified Patents challenge (IPR2023-00029), the PTAB found the patent's asserted claims unpatentable, and the Federal Circuit affirmed in March 2026, ending enforcement of those claims. No merits rulings specific to Constant Contact are reflected in the tracked data.
