Sovereignty

01Where Europe is

European institutions and member states are reducing their dependency on US-controlled consumer messengers in three distinct ways. They should not be flattened together.

Legal pressure

The European Commission sent WhatsApp's owner a Statement of Objections on 9 February 2026, covering the European Economic Area except Italy. Italy's competition authority, the AGCM, imposed its own interim measures on 24 December 2025. Brazil's CADE opened a parallel track in January 2026; on 6 March 2026 the platform confirmed that rival AI chatbots could operate on its business API in Brazil, for a fee. The EU General Court gave a split verdict on 3 June 2026: one gatekeeper designation maintained, another annulled. The DSA designated WhatsApp a very large online platform on 26 January 2026, for its Channels only. None of these is settled. Each is monitored.

Platform terms

WhatsApp's business terms, updated on 15 October 2025 and in force from 15 January 2026, bar AI providers from WhatsApp where AI is the primary function, as the platform decides at its sole discretion. The carve-out for purpose-driven verticals, where AI is incidental or ancillary to a regulated commercial task, stays. WhatsApp business data is not used to train or fine-tune AI models; that condition applies wherever the customer is.

Operating permission

Today it is jurisdiction-specific: the European Economic Area except Italy under the business terms; Italy under the AGCM's interim measures; Brazil under the CADE's interim measure and the platform's confirmation of 6 March 2026. A responsible operating posture names the jurisdiction instead of flattening it to “the EEA plus Brazil”.

The substrates

Three EU-aligned messaging substrates have working public-sector traction today: Tchap in France, built on Matrix and operated by DINUM with ANSSI security validation (600,000 registered users and over 500,000 monthly active users as of May 2026); BundesMessenger in Germany, built by BWI on modified Matrix software; and BwMessenger, the German armed forces' messenger, with over 100,000 active users. Belgium, the Netherlands, Sweden, Greece, the European Commission and Luxembourg are moving too. The word “replacement” applies only where public-sector use is evidenced. More on the Substrates sheet.

02Where Seldon is

Our position is dependency reduction, workflow portability and sovereignty options, for private-sector commerce in Spain and across regulated European verticals. The substrates themselves are the work of others: the Matrix ecosystem, OpenDesk, the EUDI Wallet, GAIA-X, EuroStack and the builders around them. Seldon builds the vertical workflow layer that can move as those options mature.

The architectural answer is transport-agnostic: one core that holds the conversation logic, the customer journey, the data controls and the compliance posture, and one adapter per channel for that platform's constraints.

Matrix is the first sovereignty-aligned channel Seldon is validating. Its governance, subprocessors, administration, backups, federation and data residency are not validated end to end yet. That is a position, not a production claim.

03What we build

A vertical core that works on the channel customers use today: WhatsApp, live for Cambialeón and QuiqSim. Matrix is in validation as the first sovereignty-aligned channel, and a second adapter is next, pending engineering scoping. The conversation logic, the customer journey, the data controls and the compliance posture live in the core. The messaging app is replaceable.
