Top Artificial Intelligence Startups in California, US

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.

Kinelo manages the new type of hybrid team that will emerge in the future: humans+AI working shoulder-to-“shoulder”. Our first product helps human software engineering teams deliver more efficiently and more reliably by assisting in coordination and engineering management. But it’s built on a foundational layer that ingests data, knowledge, and process across communications and systems, exposing that to humans and AI alike. Eventually, Kinelo will become a proper human+AI orchestration layer, managing entire companies, and our goal is to have Kinelo run Kinelo (we already dogfood it today). We’re looking for high ownership individuals to join our small team and shape its direction. We also just opened a new SF office and new hires will have the ability to help shape company culture, engineering practices, architecture, and roadmap. We’re well-funded (just raised another round), founded by a serial founder, anti-bureaucratic, and highly technical.

Every niche has outliers — posts doing 5×, 10×, 13× above average. Most creators and agencies never figure out why. They scroll for inspiration, tab-switch to ChatGPT, paste a transcript, explain their niche from scratch, get generic output back, then spend 40 minutes editing it to sound like them. And still don't know if it'll work. XCut AI fixes that. Paste any URL — a video, a competitor's Meta ad, an Instagram carousel — and XCut finds the outliers in that niche, extracts exactly why they performed (hook, structure, pacing, retention triggers), and generates your version: script, carousel, thumbnail, or ad creative. In your voice. In 60 seconds. Five dedicated agents cover Facebook, Instagram, TikTok, YouTube, and Meta Ads — each built for that platform's native format. Every major AI model included: Claude, GPT, Gemini, Grok, DeepSeek. We're a small, seed-funded team building for creators, marketers, and agencies who ship content at volume. 1,000+ users and growing, entirely organic so far. Free to start. No credit card required.

We’re a team of two UC Berkeley PhD grads starting a company (currently in stealth) around the MemGPT project (10k+ GitHub stars). The founding team comes from the same research lab and PhD advisors at Berkeley that produced Spark (→ Databricks) and Ray (→ Anyscale). We have deep expertise in both AI and systems, are currently hiring a founding team of exceptional engineers to join us in building the next generation of LLM agent technology.

AI-powered, end-to-end simulation and operating platform that helps companies develop, manage, and optimize standalone and hybrid storage projects.
