Larridin has raised $30 million in a Series A round. Pelion Ventures led the deal. Andreessen Horowitz and Gradient Ventures, both earlier backers, joined again, along with several new investors. Larridin announced the raise on November 2, 2026. The round brings its total funding to about $47 million.
Larridin builds a platform that measures the value of AI at work. It tracks AI adoption, productivity, and spend across both people and agents, and links the cost of AI to the output it produces. The company is based in South San Francisco.
What does Larridin do?
Larridin is an AI value measurement platform. As companies roll out AI tools and agents, they struggle to tell what is working. Larridin answers that. It connects data on how people and agents use AI, measures the output, and ties it back to spend. It also flags which workflows are worth automating next.
This is a new kind of tool for a new problem. Most companies now pay for many AI products at once, but few can prove the return. Larridin turns that guesswork into numbers a leader can act on.

Why does measuring AI agents matter?
Measuring AI agents matters because spend is rising fast and proof of value is thin. Companies are adding agents across support, sales, coding, and operations, but most cannot say what each one returns. Without that, budgets get cut when results are unclear. A measurement layer lets a company see which agents pay off, which do not, and where to invest next. That is the gap Larridin is built to fill.
What results does Larridin report?
Larridin reports strong numbers from its customers. The platform has measured more than 2 billion AI sessions and tracked over 82,000 workflows end to end. Across its customers, it reports an average 47 percent increase in measurable team output, and a median of $2.4 million in AI spend optimized within the first year. Its customers include SurveyMonkey, Klaviyo, Gainsight, Vertiv, and TigerConnect.
Why does this round matter?
This round matters because it backs a new category. The first wave of agent funding went to the agents themselves. Larridin is part of the next wave, the tools that manage and measure them. As the agentic AI landscape matures, companies need ways to govern and prove the value of the agents they deploy. That makes measurement one of the clearest new opportunities in the market.
What is next for Larridin?
Larridin will use the money to grow its platform and reach more enterprise customers. The challenge is trust in the numbers. For a measurement tool to matter, leaders have to believe the output it reports. Larridin is led by CEO Russ Fradin, and it is betting that proving AI value will become a must have as agent spend climbs.
