South San Francisco startup Larridin raises $30 million to show companies what their AI spending buys
Its software tracks who uses AI tools at work, what it costs and what gets done. At one customer, a single engineer ran up about 65% of a team's AI bill in a week, the company says.
Larridin, a South San Francisco startup that measures whether companies' AI spending is paying off, has raised $30 million, the company said Monday. SiliconANGLE also reported the round.
The money is a Series A, a startup's first big round after early seed funding. Pelion Ventures led it, joined by earlier backers Andreessen Horowitz, the Menlo Park venture firm, and Gradient Ventures, plus new investors. Larridin has now raised $47 million. It did not disclose its valuation.
What it does
Businesses are paying fast-rising bills for AI tools that charge by the amount of text they process. Larridin's software connects data on who uses those tools, what they cost and what work comes out, for both employees and AI agents, programs that do tasks on their own. Fradin argues the usual yardsticks, such as counting paid seats or logins, do not show whether AI is actually helping, SiliconANGLE reported.
The company says one customer found 92% of its engineers used AI, yet one engineer accounted for about 65% of the team's AI spending in a week. At another, two AI coding tools doing similar work differed 66 times in cost per finished code change. Larridin also claims a 47% average rise in its customers' measurable output, a figure that has not been independently checked.
Enterprise AI has moved quickly from innovation budget to financial accountability
Its new report found AI-assisted code changes rose from 35% in April to 62% in September, while waits for human review grew 50%. Customers include SurveyMonkey and Gainsight.
