Lightfield, a San Francisco startup building a customer relationship management system designed for AI agents, has raised $47 million in early-stage funding. Andreessen Horowitz led the Series A, announced September 9, 2026, with Lightspeed Venture Partners, Coatue, Greylock, Maverick Capital, Audacious, and Alumni Ventures also taking part.
The company, incorporated as Magical Tome Inc. and based in California, is making a direct run at Salesforce and HubSpot. Its argument is that as businesses hand more work to autonomous AI systems, they will need a different kind of system of record, and that the architecture of legacy CRMs was built for human users rather than agents.
In a conventional CRM, customer relationships live in static fields, close dates, and scattered notes, stored in a shape agents struggle to parse. Feed an agent that kind of incomplete, messy data and the output is unreliable. Lightfield’s answer was to rebuild the CRM from the ground up so the structure makes sense to agents by default. Rather than waiting for a sales rep to update the record after a call, the system takes part in every customer interaction, captures the relevant details automatically, and organizes them in a format agents can read and act on.
Four design choices separate the product from older platforms. The record updates itself, continuously pulling in interactions from email, calendars, Slack, and LinkedIn. That data feeds a world model of the business that maps interactions to specific accounts and deals and tracks how they change over time. An agent harness requires AI agents to operate through a standard software development kit and a code sandbox where their actions can be monitored. And the whole system is open, with everything readable and writable through APIs, command line tools, and the Model Context Protocol, so customers can build automations on top of it.
Since launching the platform in November, Lightfield has signed up more than 5,000 companies, from early-stage startups to scaling enterprises, and dozens of them have replaced Salesforce with it outright. The new funding will go toward growth and expanding what the company’s agent can handle for customers.
