Zaro raises $5.1M to build opposite of Salesforce Agentforce

London startup Zaro raised $5.1 million in a pre-seed round led by Cherry Ventures to build an AI workspace owned by the company, not its vendors. The team previously built Agentforce at Salesforce. Zaro replaces separate AI tools with a shared context layer and routes routine tasks to cheaper models, cutting costs roughly 10-fold.
