Eleven months after buying TrueData to strengthen its US identity graph, ID5 is shedding the audience data business that came with it. The London and New York identity provider confirmed the sale to Cloud Technologies in an October 1, 2026 post titled “Staying Focused on Identity.”
What changed hands
Cloud Technologies has acquired TrueData’s third-party audience data business and the TrueData brand, according to ID5. The unit will keep operating under the TrueData name in North America, as a wholly owned subsidiary of Cloud Technologies.
ID5 keeps the identity graph, the team and the US expertise it originally wanted. Mathieu Roche, ID5 co-founder and CEO, confirmed the deal on LinkedIn and described the audience marketplace as “a small part” of TrueData’s overall business. Ophelia Livingstone was named CEO of TrueData under its new owner. No price was disclosed.
Why selling makes strategic sense
ID5’s argument is about position, not just portfolio. As an independent identity provider, it claims its role only works if it has “no audiences to sell, no media to buy.” An identity vendor that also sells segments competes with the data platforms and brokers that license its graph to build their own audiences.
That logic runs against the usual adtech direction. Where Experian bought Audigent in December 2024 to add data activation, ID5 is narrowing itself to the identifier and the graph. It is betting that a neutral referee earns more trust from publishers, platforms and agencies.
What changes for marketers
For most teams, the products don’t disappear; the counterparty does.
- Buyers of TrueData audience segments now deal with Cloud Technologies’ subsidiary, not ID5.
- Clients using ID5’s identifier or identity graph continue to deal with ID5.
- Companies that used both TrueData segments and ID5 identity are back to two suppliers for the audience side.
That split matters because the 2025 acquisition promised shared clients “one unified solution.” The audience side is now outside ID5 again, and the documents do not say whether TrueData segments still rely on ID5’s graph or match tables.
Watch the Safari backdrop
The sale lands during a rough stretch for identity vendors. Two ID5 sync domains recently appeared on a WebKit blocklist alongside The Trade Desk, LiveRamp and Unified ID 2.0 domains after iOS 27. ID5 and Roche do not link the divestiture to that change, but the timing shows why a clear neutrality pitch matters now.
For marketers, the move is a reminder to audit which vendor actually supplies each data product and to ask what happens to matching and measurement when an identity and audience business split.
