The first Behavior Design Engine for the enterprise. Sequen isn’t retrofitted AI search or recommendations. It rethinks relevance from first principles. Sequen introduces the first foundational Large Event Model (LEM), trained on billions of user event sequences and built natively on a reinforcement learning infrastructure. LEMs are specialized neural networks that predict the next user event—just as LLMs predict the next word. Sequen’s LEMs are pre-trained on billions of user-site interactions and fine-tuned to optimize for the outcomes you care about. No more fixed pipelines with fragmented infrastructure. Sequen replaces them with a single endpoint that adaptively handles all phases of personalization via LEMs and memory models—all through a sub-25ms API.

Laborup is the #1 AI powered talent platform for America’s industrial workforce. We use AI to create jobs, not take them away. We help HR and plant leaders hire and keep the skilled workers who keep plants running: machinists, welders, maintenance techs, operators, industrial electricians, and engineers. USA Today called us the “LinkedIn for blue collar workers,” and Forbes profiled our work in “How AI Is Solving America’s 1 Trillion Dollar Manufacturing Labor Crisis.” Today we work with manufacturers from 50 person shops to large public companies with tens of thousands of employees, and the story is the same everywhere. It is hard to find talent, hard to keep good people, and staffing costs keep rising. In a market where filling critical industrial roles can take months and turnover is constant, Laborup helps teams move qualified workers from first contact to on site interview in days instead of weeks and keep them on the floor longer. Most of the workers our customers need are not on LinkedIn or the usual job boards. Laborup uses AI to find this hidden workforce, call and text them, screen and qualify them, build real profiles, and match them directly to the plants and roles where they can succeed. For workers, that means real, permanent roles at serious manufacturers, not one off gigs. For companies, it is durable infrastructure for hiring and retention at scale in a labor market that will stay tight for years. We work across nuclear, defense, and advanced manufacturing, as well as sectors like aerospace, automotive, and food production. Teams that use Laborup hire 5 to 10 times faster, see around 3 times better retention, and cut cost per hire by up to 50 to 70 percent. That turns into fewer empty shifts, fewer missed orders, more stable teams, and more capacity without more headache. We are building the modern talent system for America’s industrial base with a simple long term goal: put a billion industrial workers to work in good jobs that matter.

Numa helps auto dealers run their stores with AI Agents. AI agents who answer every single call, rescue every missed call. AI agents who automate appointment scheduling. AI agents who flag customer heat cases. AI agents who send RO status updates. AI agents who coach service advisors. AI agents who recognize and fulfill equity trade-in opportunities. Numa is the only auto dealership AI trusted by 1000 dealers. Numa is also the only dealership AI that blends Silicon Valley DNA with Automotive DNA. Silicon Valley serial entrepreneurs, 50+ AI / Machine Learning & PhD Engineers and 150+ years combined of dealership GM experience. It’s like if Roger Penske and Steve Jobs joined forces to raise $50M from Google, Mitsui (500+ rooftops) and Tesla’s founding investor to build AI for dealerships. Numa tackles the dealership communication crisis head-on. We’ve handled 20M calls for dealers in the last year (10% appointment related). For AI newbies who show flashy demos and have few real customers, remember they can only help with up to 10% of calls. Numa handles all communications across voice, text, web. Because Numa is a shared inbox for customer comms, we give dealership leaders unprecedented visibility into communications... and the accountability that comes with it. No more wondering how many customers are behind those red blinking lights on your phones and who hasn’t responded. Numa helps dealers manage the work of their team, humans and AI together. With Numa, dealers respond faster — from 23 hrs average to under 20 min. We rescue thousands of ROs and millions of RO $ per year, per rooftop. Also, dealer service advisors love working in Numa. They learn and ramp faster and stay longer — saving dealerships countless $ in training, recruiting and lost productivity. Numa drives exceptional dealer communications which drives exceptional CSI which drives lifelong customer loyalty and repeat business. Altogether, this is the AI-native dealership movement.
