In 2021, the CEO of IDG Inc. publicly identified the upper-funnel B2B martech opportunity at $20 billion. IDG's operating arm was structured to capture it: 60 years of editorial brands, 44 million decision-makers, four acquired martech platforms, Blackstone backing, an IPO path. The 2022 ad-market downturn closed the IPO window. Foundry was sold to Regent LP in March 2025. Foundry-the-business runs profitably today; Foundry-the-vehicle-for-the-$20B-thesis no longer exists.

In December 2024, Informa PLC's tech assets — NetLine, Industry Dive, Omdia, Canalys, InformationWeek — merged with TechTarget to form Informa TechTarget (NASDAQ: TTGT). Combined revenue ~$490M; stated five-year ambition $1B; stated TAM, in their own SEC filings — “a $20bn addressable market at the intersection of Technology and B2B Marketing.” The second sophisticated, publicly-accountable operator to independently name the same opportunity. Two operators, four years apart, converging on the same number.
