Rundoo Raises $30M Series B to Expand AI-Native Operating System for Independent Supply Stores

Rundoo, a Redwood City-based AI software company serving independent supply retailers, raised $30 million in Series B financing led by Battery Ventures, with participation from existing investors Bessemer Venture Partners and CRV. The round brings Rundoo's total funding to $48 million and was announced August 19, 2026. Battery Ventures General Partner Michael Brown led the firm's investment and will join Rundoo's board alongside existing board members from Bessemer and CRV. The new capital will fund engineering team growth in Redwood City and go-to-market team expansion in Chicago.

What Rundoo Builds

Rundoo provides an AI-first operating system for independent supply stores: hardware stores, paint retailers, lawn and garden centres, farm and feed suppliers, and lumber yards. The company currently serves more than 500 stores across the United States, Canada, and the Caribbean. Its platform handles point-of-sale operations, inventory management, purchase ordering, customer accounts, and the AI-driven pricing and recommendation layers that help independent stores compete with large chains and big-box retailers on operational efficiency.

The company was built on the insight that independent supply retailers are a large, fragmented, and persistently underserved segment. Unlike retail categories like restaurants or convenience stores that attracted technology investment early, the independent supply store category runs on legacy systems ranging from ageing desktop software to paper-based manual processes. The category serves critical infrastructure needs: a hardware store serves contractors, the farm and feed store serves agricultural producers, and the lumber yard serves residential and commercial construction. None of these customers have the luxury of delayed service, which makes software reliability and integration depth more important than in consumer-facing retail.

Why Battery Ventures Led

Battery Ventures is a technology investor with strong conviction in vertical SaaS businesses targeting industries where software adoption has lagged the broader enterprise market. Its previous vertical SaaS investments include companies in automotive, food service, healthcare, and industrial distribution. Rundoo fits Battery's playbook precisely: a category-defining product in a large underserved segment, with enough existing customer traction (500+ stores) to demonstrate repeatability but enough greenfield market ahead to justify significant capital deployment.

This is similar to the thesis Battery applied to companies like Curbside (grocery pickup software) and other niche category leaders where a first-mover vertical platform can achieve dominant market share before large horizontal players notice the category.

What This Means for Founders

Rundoo's raise is a useful case study for founders in vertical AI: the combination of a genuine distribution problem (500+ stores already paying) and a clear expansion path (serve the thousands of stores not yet using modern software) is the diligence-passing combination that top-tier investors want to see at Series B. The presence of Bessemer and CRV from earlier rounds, following on into Series B, signals that the company's performance between its earlier raise and now justified continued backing.

For founders building vertical AI products in overlooked industries, the investor match tool on AngelLinx can help identify which funds have portfolio companies in adjacent verticals and would therefore bring relevant operational expertise alongside capital. Understanding your customer acquisition cost in vertical markets, where sales cycles are longer and customer relationships are more durable than in horizontal SaaS, will be the central metric in your Series B conversation.
