Top Artificial Intelligence Startups in California, US

We’re a hypergrowth AI startup backed by top-tier VC firms. We’ve created a new paradigm for enterprise artificial intelligence with a breakthrough technology called Organizational Memory (OM1). It’s fundamentally reshaping how people do work. Unlike any other AI product, OM1 builds “a brain” for companies–knows what’s happening in real time across the whole business, and has all the output capabilities of a human employee. Roles like Product, Engineering, G2M, and Management will never be the same. And while we’re starting by selling our technology to other software businesses, we have the ability to serve hundreds of different industries. We're not just building another productivity tool. We're ushering in a fundamental revolution in how humans do work. With proven product-market fit, rapid YoY ARR growth, and household-name customers, we’re expanding our team to dominate what will be a $10T+ industry. And we’re only just getting started.

Imagine websites that adapt to every visitor dynamically, driving revenue autonomously. That’s the future Fibr AI envisions.
Founded by serial entrepreneurs Ankur Goyal (2x) and Pritam Roy (3x) — with backgrounds from IITs and Stanford — we spotted a gap: today’s static websites fail marketers. Fibr AI (fibr.ai) is an enterprise-grade AI Agents platform, building an AI-CRO (Conversion and Revenue Optimization) Agentic Workforce built for consumer marketers that automates optimization workflows in marketing - experimentation, personalisation and performance - to enhance web experiences and drive conversions at scale. This enables companies to run 100x more experiments at 10x the speed of traditional CRO methods, and almost at half the cost of fragmented tools, agencies, or experts. Early results with design partners show promise — think 1,500 tailored landing pages to drive ~20% conversion uplift. Fibr AI integrates seamlessly with existing Martech stacks like CRO tech stack, CDPs, ad platforms, and email systems to ensure that website experiences reflect all the data and insights generated across those channels, making the website an intelligent, responsive part of the marketing ecosystem. Fibr AI eliminates the bottleneck of current CRO - relying on human resources or developers, and replaces traditional CRO agencies (10x market size to CRO SAAS) offering a smarter, faster, and more efficient approach to conversion and revenue optimization. Our Vision? Turn interfaces (websites) into living, self-optimizing revenue driving engines.

Scrollmark is building SocialGPT, the first AI system specifically designed to decode social media algorithms and give creators, brands, and agencies the insights they need to succeed across platforms. Social media algorithms change constantly, leaving creators and brands scrambling to understand why their engagement suddenly drops. Most tools focus on scheduling and analytics; we focus on understanding why content succeeds or fails before you even post. Our AI engine continuously analyzes thousands of viral posts across social networks to identify: - Breakout patterns in the critical first 30-60 minutes after posting - Niche-specific trends that matter to your exact audience - Content attributes that drive engagement (hooks, captions, timing, formats) - Algorithm signals that predict viral potential Check it out at gpt.social Want to be a part of the Scrollmark Crew?
