About

We're a team building the data infrastructure that powers the world's most important AI systems. Founded in San Francisco in 2016, we've grown from a small startup to a company of 1,000 people united by a single mission: developing reliable AI systems for critical decisions. We work with AI labs, government agencies, and Fortune 500 companies, providing the high-quality data and full-stack technologies they need to build, deploy, and oversee AI applications that actually work.

What we do day-to-day is intricate but straightforward: we help teams manage the entire machine learning lifecycle by combining cutting-edge technology with operational excellence. We've processed over 15 billion human decisions to train AI models and have paid out $1 billion to contributors globally. Our platform handles everything from RLHF and data generation to model evaluation and safety alignment for some of the most advanced LLMs and generative models out there. We're proud to be trusted by leading organizations to power their AI systems, but we know the work is never done - better data really does mean better AI, and that's what we're constantly chasing.

Graphcore

We're building the future of AI compute at Graphcore, where our team of semiconductor, software and AI experts is creating the complete AI compute stack from silicon to datacenter infrastructure. We developed the Intelligence Processing Unit (IPU), a groundbreaking processor specifically designed for machine intelligence that delivers leading-edge AI performance with unprecedented efficiency. Our silicon engineers are doing pioneering work, including being the first company in the world to bring a Wafer-on-Wafer AI processor to market, while our software and AI teams build new tools and optimize popular AI models to lead the market for performance, efficiency, and usability. We're optimistic about a future where people live healthier, fairer, more informed, and more sustainable lives. Our AI technology aims to bring democratized intelligence that everyone can benefit from. Now as a wholly owned subsidiary of SoftBank Group, backed by significant long-term investment, we're expanding our teams around the world to solve the toughest problems in AI computing. We're bringing together the brightest minds in a place where everyone has the opportunity to make an impact on the company, our products, and the future of artificial intelligence.

SQ

SquareTrade

We're SquareTrade, also known as Allstate Protection Plans, and we've been changing the way people think about protection plans since 1999. Back then, extended warranties were stuck in the past - the protection was flimsy and the customer service was awful. We knew we could do better, so we set out to create protection plans as innovative as the products we protect, and to treat every customer the way we'd want to be treated ourselves. Today, over 140 million customers trust us to protect everything from smartphones and electronics to appliances and furniture. We partner with many of the largest retailers and mobile carriers in the world, including Walmart, Costco, The Home Depot, and Amazon. Our mission is simple: help people enjoy life with the products they love and rely on. We offer same-day phone repairs, one-visit in-home service appointments whenever possible, and easy online claims available 24/7. Sustainability is at the core of what we do - by helping customers make their purchases last longer and work better, we're reducing waste and making a real difference together.

HighLevel

At HighLevel, we believe in empowering agencies and businesses to thrive through innovation and community. Our AI-powered business operating system has grown from a startup to serving over 2 million businesses worldwide, all while maintaining our remote-first culture across 1,500+ team members in 15+ countries. We process over 15 billion API hits and 2.5 billion message events daily across our microservices architecture, handling 470 terabytes of data. But what really drives us isn't the metrics - it's the real businesses we help grow, the leads we help capture, and the relationships we help build. We're building more than software; we're creating a global community rooted in creativity, collaboration, and impact. Our platform consolidates countless marketing tools into one white-label solution - CRM, email, SMS, funnel building, appointment scheduling, and automation - so agencies can focus on what matters: delivering results for their clients. We listen to our users through our community-driven Ideas Board, celebrate innovative thinking, and put people first no matter where they call home. When you join HighLevel, you're not just adopting a tool - you're joining a movement of marketers helping marketers succeed.

Fractional AI

Fractional AI exists to solve one of the biggest bottlenecks in enterprise AI adoption: the talent gap. While every C-suite recognizes that AI could transform their business, most companies lack the elite engineering talent needed to build production-grade AI systems. Fractional AI bridges this divide by deploying world-class engineers who specialize in applied generative AI - turning experimental projects into measurable competitive advantages. They don't just advise; they build, shipping custom AI solutions that automate workflows, reduce costs, and unlock revenue streams that off-the-shelf tools can't touch. What makes Fractional AI different is their services-first model and obsession with engineering excellence. Rather than forcing companies into a one-size-fits-all product, they embed directly with client teams to solve their specific problems - whether that's automating content moderation for Change.org, building API connectors for Airbyte, or reducing LLM hallucinations by 80% for Zapier. Their San Francisco-based team of former founders, CTOs, and senior engineers brings cross-industry expertise that internal teams can't match. They see patterns across companies, stay on the bleeding edge of what actually works in production, and transfer that knowledge back to their clients. The mission is clear: inspire an elite team of engineers to solve the world's most valuable problems using AI, and make every company they work with 2-10x more productive in the process.

BA

Baseten

At Baseten, we're a team of engineers and designers who believe the best products emerge when you work directly with the people using them. Our engineers spend time embedded with customers, learning from their operational challenges and turning those insights into infrastructure that just works. We ship daily, optimize obsessively, and measure our success by the real-world impact of the AI products running on our platform. We're an internationally diverse group of builders who take pride in our craft but not ourselves too seriously. Whether we're optimizing kernel-level performance for inference or building delightful developer tools, we believe software quality comes from small teams with real ownership. We optimize for shipping, not process - which is why we've been focused on rapid iteration and hands-on problem solving since day one.

Parloa

We're building the AI agent management platform that's transforming how enterprises handle customer service. Founded in 2018 by Malte Kosub and Stefan Ostwald, Parloa helps companies like Allianz, Booking.com, and IKEA automate their contact centers with AI agents that can handle millions of conversations while maintaining a human touch. Our team of 380+ people across Berlin, Munich, and New York is focused on closing the gap between companies and their customers through intelligent, scalable automation. What drives us is the belief that every customer interaction should be as easy as talking to a friend. We've poured years into developing technology that doesn't just respond to queries but actually understands context and builds relationships over time. After reaching unicorn status and securing $350 million in Series D funding at a $3 billion valuation, we're scaling rapidly to bring our AI-powered platform to more enterprises worldwide. We're not just automating support - we're reimagining how businesses and customers communicate.
