Tagman

Marketing · Duluth, United States · Founded 2007

Leading global Tag Management System (TMS), Marketing Data, and Marketing Attribution provider. Acquired by Ensighten MoreLess

Established in London in 2007 by co-founders Jon Baron and Paul Cook, TagMan carved out a significant niche in the burgeoning digital marketing landscape as a pioneering tag management system (TMS). The founders identified a critical market gap for a unified solution to manage the numerous marketing and analytics tags that were becoming cumbersome for website owners to handle individually. This realization led them to create a platform that essentially invented the tag management sector.

TagMan's core business revolved around its platform that allowed digital marketers and e-commerce professionals to deploy, manage, and unify data from various third-party tags on their websites. This streamlined operations, improved website performance, and provided a clean, unified layer of first-party and third-party data. The company's services were crucial for clients to analyze the customer's journey to purchase and understand advertising impact through tools like a visual insights suite, marketing attribution, data optimization, and conversion tracking. Serving over 400 brands globally, its client roster included major enterprises like Virgin Atlantic, Marriott, John Lewis, Spotify, and DIRECTV.

The company's growth was financed through several funding rounds, accumulating over $13.6 million. Key investors included Greycroft, Inovia Capital, SVB, and angel groups like Cambridge Angels and London Business School Enterprise 100. The first funding round occurred in February 2010, followed by a Series A in 2011 and a subsequent $5 million round in 2013 to fuel global expansion. This financial trajectory culminated in its acquisition by Ensighten in March 2014, a move that established the combined entity as a market share leader in the enterprise data and tag management space.
