Short answer
SIforce is the name Salesforce CEO Marc Benioff announced on October 9, 2026 for AIforce, the Salesforce layer that brings Salesforce data, context and agents into the tools people already work in. It started as Headless 360 in April 2026 and was renamed AIforce in September 2026.
SIforce (formerly AIforce) explained
Headless 360, announced at TrailblazerDX in April 2026, made the Salesforce platform available to agents as APIs, MCP tools and command-line commands. Salesforce renamed it AIforce in September 2026 and launched it at Dreamforce. Benioff announced the SIforce name on October 9, after the federal government adopted Super Intelligence (SI) as its term for AI.
On October 13, 2026, salesforce.com still used the AIforce name, so Vantage Point writes "SIforce (formerly AIforce)" until Salesforce's own pages change.
How Vantage Point helps: we connect Claude and other agents to Salesforce with permissions that follow the signed-in user. See Claudeforce and Claude + CRM integration (MCP).
