Top Tech Startups in California, US in 2026

The physical world runs on some of the most complex supply chains in existence. Distributors, manufacturers, and their partners manage thousands of SKUs, juggle siloed systems, and rely on tribal knowledge that never gets captured. The tools built to run these businesses—legacy ERPs, spreadsheets, disconnected portals—weren't designed for the speed, intelligence, or scale the industry now demands. We're changing that from the ground up. Matterhaul sits above the systems these businesses already run. We unify their data into a single intelligent layer, deploy AI agents across quoting, order entry, procurement, and dispatch, and surface the insights teams need to move faster and make better decisions, without ripping out what's already in place. That's the wedge. The vision is bigger. As we build the unified data layer and the agentic workflows on top of it, we're assembling the foundation for something the industry has never had: a purpose-built, AI-native platform for the physical world that doesn't just automate what ERPs do today, it does what they were never capable of. Capturing expert judgment. Compounding institutional knowledge. Turning every transaction into a signal that makes the next one smarter. We're a small team with deep roots in this space. Matterhaul's founders grew up in the trades and spent careers building systems and products for the physical world at companies like Stripe, Verkada, and Cisco Meraki. We're backed by leading investors, based in San Francisco's SOMA/Transbay neighborhood, and we believe in being close to our customers and to each other. We spend time on job sites, in distribution centers, and alongside the operators who run these businesses every day. We move fast, ship often, and build for the people who actually do the work.

We help people turn memories into personalized figurines for meaningful gifting

At CenterCheck, we’re transforming how property owners, retail stores, and brokerages gain insights into store-level performance nationwide. Our platform delivers market-leading store-level sales data and customer intelligence that empower clients to develop a more productive real estate portfolio. We've developed a proprietary AI model that predicts store-level sales better than anyone else on the market. We provide industry-leading clarity for anyone with a stake in the physical world.

We are an asset management startup building a proprietary reasoning engine to automate fundamental analysis. We are building Alka Arbiter, a system capable of ingesting vast, unstructured market datasets and transforming them into clear, risk-weighted investment mandates. Unlike standard AI wrappers, our engine is designed to show its work, creating a fully auditable record of why a decision was made. We are looking for builders to help us bridge the gap between stochastic AI models and the rigorous reliability required to manage fiduciary capital.
