What changed across the timeline
Infrastructure became a product
Masumi and Kodosumi created protocol and deployment layers; Sokosumi turned them into a workplace buyers could access.
Experiments became an operating model
House of AI connected previously separate data, creative, media and agent initiatives under one architecture.
Partners became embedded capabilities
Luma AI, Akkio, AMBOSS, GWI, NMKR and Cardano contribute different technical or data layers rather than one generic partner programme.
Enterprise work gained a self-service edge
Custom Agentic Services remain, while AI Coworkers offer smaller teams defined roles and deliverables without a bespoke build.
Source policy for this section
The record is intentionally narrower than every claim found online.
- Prefer official Serviceplan Group, agency, partner and product pages
- Use trade press when it contains a named launch detail missing from primary pages
- Label provider metrics and maximum savings as provider claims
- Do not turn logo walls into partnership announcements
- Record ambiguity instead of selecting the more impressive version
Timeline questions
When did Serviceplan launch the House of AI?+
The group reported the House of AI ecosystem in its FY 2024/25 results, and the full public architecture was visible by late 2025 and 2026. No single separate launch date covers every component.
When did Sokosumi launch?+
Serviceplan Group's public announcement is dated 25 June 2025.
When did Serviceplan start Agentic Services?+
Serviceplan material associates the offer with 2024, while a Masumi re-publication carries a 2025 date. This guide treats the exact month as ambiguous and avoids a more precise claim.
How current is this guide?+
The source review and factual cutoff are 26 August 2026. Product capabilities, organisation and performance claims can change after that date.
SokosumiWhat the House of Communication learned about AI, as a product you can use on Monday
Sokosumi is the marketplace of named AI coworkers built by Serviceplan Group with NMKR. You brief a coworker like a colleague; the task shows on a shared board and comes back as a file: a PDF, a deck, a spreadsheet or a dashboard.
