Top Tech Startups in California, US in 2027

We are building conversational AI agents for businesses.

General Compute is the neocloud for alternative chips. Inference is fragmenting: purpose-built silicon from SambaNova, Cerebras, Positron, d-Matrix, and others already beats GPUs on decode, and we productionize that hardware — we buy the racks, find the data center space, and run it for our customers. Each piece of hardware runs the workload it's actually built for: prefill stays on GPUs, decode moves to the chip built for it, and today that means generating tokens 5–7× faster than existing GPU-based competitors. Our customers are frontier labs, fast-growing AI application companies, and asset-light clouds. We closed a $15M seed round in May 2026, and have since closed a $400M debt facility — $100M funded upfront by Upper90, with the balance available for drawdown — collateralized by our inference chips.

Compute is a commodity. We think people should buy it like one. Startups shouldn’t be forced to buy a year’s worth of compute time in order to get market rate and compute providers shouldn’t go bankrupt because they can’t fully book their clusters. At SF Compute , our goal is to solve this issue the same way this was solved for every other commodity — by building a venue where compute contracts are traded in real-time and by bringing a new kind of participant into the supply chain, traders. If we succeed, buyers will be able to get a good price for any order, whether it’s 32 H100s for a month or 8,000 H100s for an hour, and sellers will instantly book out their clusters because traders will speculatively buy them, for a spread. Every FLOP will flow through us somewhere in the supply chain. What Brent is for oil, we will be for compute.

Grovyn is a product-focused software engineering company that works closely with startups and growing product teams to build reliable, high-quality software. We partner with founders and engineering leaders when execution matters most. Our work typically sits at the core of a product, whether that is building new features, scaling platforms, improving performance, or helping teams move faster without compromising on quality. Grovyn was built with a simple belief that strong engineering and clear ownership create better products. We focus on deep collaboration, practical decision-making, and long-term thinking rather than handoffs or heavy process. Our team brings hands-on experience across modern web platforms, APIs, mobile applications, and real-time systems. We integrate closely with internal teams and operate as an extension of the product organization, not as an external vendor. As a founder-led company, we stay involved at every stage of the work. We value trust, clarity, and accountability, and we care deeply about the outcomes we help our partners achieve. We work with teams that value craftsmanship, speed, and ownership, and we build software that is meant to last.

Real to sim — our automated stack turns prompts, images, and CAD models into visually and physically accurate, sim-ready assets and scenes, so simulation decisions match what actually happens on the floor. Sim to real — generate unlimited asset and scene variants, expand training policies, and evaluate out-of-distribution cases that are hard or unsafe to reproduce in the real world. Palatial works where you already do: an Isaac Sim plugin, MCP integrations for Codex and Claude Code, and a web dashboard — with output for Isaac Sim, MuJoCo, and Newton. Every asset ships sim-ready: precision geometry, physics-solver-friendly topology, PBR materials, accurate mass/inertia/friction, and articulated joints.

Hirebase is a single, unified system of record for hourly workforce operations. It unites onboarding, configurable training verification to ensure readiness before dispatch, scheduling, geofenced attendance, wage calculation, and exit workflows, replacing scattered, disconnected tools with one system. Hourly, field-based work runs on dynamic shift schedules, compliance checkpoints that verify real-time activity, and a workforce constantly in motion between locations and roles. Traditional HR systems are built for desk-based, salaried employment, forcing operators to bend static software to fit fluid workflows. Hirebase is built differently, from the ground up, for the pace and complexity of field operations. Currently there are 600,000+ strong workforce being managed through the software and we are looking at aggressive expansion globally.
