Seals is a suite of AI Employees for Wholesalers & Distributors. Instead of relying on humans to quote, take orders, collect payments, place purchase orders and enter data into ERPs. We build AI Employees that do these manual repetitive tasks for the 700k wholesalers in the US. We’re a team of three Computer Science majors, and Fernando launched and grew AT&T in Mexico to $120M ARR. Previously, we all worked together at our last YC-backed startup, building it to over $6M in revenue. It was there that we placed thousands of purchase orders with wholesalers. We realized that almost every physical product comes from B2B sales in the supply chain. However, it turns out that most of these operations are still done manually through phone and email, involving tasks like quoting, taking orders, collecting payments, entering data into ERPs, and providing support. By automating these tasks with AI agents in a human-like manner, we are creating a massive opportunity to convert $100B of payroll expenses into software spending.

Nobody's built truly proactive AI, because it requires running inference on your entire life. In the cloud, that's insanely expensive and a privacy nightmare. But not on your own chip. Every night, Sentient's on-device LLM wakes your Mac and understands what's new in your life (email, messages, files, Granola transcripts...), entirely locally, and distills it into a knowledge base. You wake up to your work already prepared: the reply you forgot, drafted from your own context; the subscription you never use renewing tomorrow, caught; the report you promised in the group chat, ready to send. Everything is one click from firing through computer use, and nothing fires until you click. Or click your Mac notch anytime and say "finish this for me." Sidekick takes over the thing you were doing with its own cursor while you move on. On-device inference at this scale was supposed to be impossible: devices too slow, and models too dumb. So we built the stack ourselves: a custom LiteRT-LM fork (KV-cache reuse, speculative decoding, custom k-quants) that runs nightly on 8 GB Macs. The user's hardware does ~90% of the compute, and their own ChatGPT or Claude subscription does the rest, so our marginal cost is ~$0, and our servers store nothing. We soft-launched late July with one Reddit post: top of r/macapps, 2,000+ users in 48 hours, $0 marketing. Free and open source for consumers; the same engine on the work stack (Slack, Granola, Linear, Notion) becomes the enterprise business. Sentient OS raised ~$1M in pre-seed, backed by YC, Afore, and the a16z Speedrun scout fund.
Sentrial is the monitoring platform for AI products in production.

We are starting with tasks such as data center construction and operations, cable and wire manufacturing, wire harness assembly, kitting, and factory packaging, where traditional automation struggles with variability, dexterity, and changing environments.
Companies use Sherloq as their single source of truth for their SQL on top of their existing data stack. Today, data-driven organizations face the challenge of giving 2 of their data analysts the same task and getting 2 totally different results from their analysis. Although SQL is the #1 coding language for data analysis, it is still managed independently on each user's internal documentation tools (notepads, Slack channels, or docx files). Creating one source of truth is an ongoing difficult process, that’s done manually and takes time to implement. Using our plugin on top of our user's existing query editors, companies can now manage their SQL code in one place. We ourselves are data users and we've built Sherloq to fit the exact needs of data teams, becoming a true alternative to the way SQL is being managed today.
Sherpa automatically optimizes websites for every human and every agent.

1.2B lbs of fish are caught everyday yet as little as 1 in 3 fish make it to a plate — most of this waste arises because fish are suffocated on boats or electrocuted on farms. Suffocation and inaccurate electrocution create stress and so acidify meat, damage quality and significantly reduce shelf-life. Artisanal techniques in high-end sushi multiply shelf-life and taste but, because of the variation in fish, are difficult to perform in a mechanical fashion. Shinkei automates traditional techniques using robotics to provide long-lasting and delicious fish for farmers and harvesters at scale.
We deploy robots that learn new tasks from a single human demonstration in the factory. We're starting in contract manufacturing, where lines change every week and both traditional automation and today's VLAs fall over. Our founding team has 20+ years of experience in robotics. Navid was part of the core team that productized Spot at Boston Dynamics and led manipulation projects there. Before that, he was at Rethink Robotics. Mojtaba led whole-body control and manipulation efforts at Amazon Robotics and was a Research Assistant Professor at Northwestern University.
We maintain the world’s largest index of short-form videos and run a human-in-the-loop pipeline to clean, segment, and label this data for AI labs.

Shor is a new Employer-of-Record built from the ground up with AI agents and stablecoins. We enable remote teams to hire and pay global employees at a fraction of the cost. The process is fast, simple, and fully compliant. Today, global payroll is broken. Payments take days, cost 5–10% in fees, and force companies to navigate complex banking, tax, and labor regulations. Platforms like Deel and Rippling solved this for large enterprises but remain too expensive and cumbersome for the millions of startups and growing remote teams scaling globally. Shor fixes this by combining autonomous AI agents with stablecoin-based settlement. Our agents handle contracts, worker classification, compliance, and payroll automatically in a simple, messaging-first experience. Payments can settle in seconds rather than weeks at a fraction of the cost of legacy providers. We are making global payroll fast, affordable, and accessible for the millions of companies left out by legacy platforms.

Made a breaking change and don't want users on your old version? One click to set a minimum version. Version gating is also completely free regardless of how many users you have.
Sidekick is an AI-powered SMS assistant for frontline workers in manufacturing, auto dealerships, and retail. The idea came from Justin's father, who owns a manufacturing facility and asked him to build a tool to help with worker onboarding, training, and organizing company knowledge. Workers text questions in any language and get instant answers from their company's documents — no app, no login, works on any phone. They can send photos of equipment for instant identification or voice memos when their hands are dirty or they're wearing gloves. Managers upload documents and record video walkthroughs; Sidekick automatically generates step-by-step tutorials and a searchable knowledge base. When Sidekick can't answer, it escalates to the manager via SMS and learns from the response, getting smarter with every interaction.

Skillsync lets you push your agents' sessions the way you push code. Everything lands in one searchable place. The best sessions become skills any agent can load. Works across your team! Today, all that thinking, what worked, what didn't, and why, is scattered across Claude Code, Codex, Hermes, whatever each engineer prefers. It vanishes when the session closes. Skillsync captures it, so every agent builds like your best engineer. The more your team ships, the smarter your agents get. Engineering culture stops being tribal knowledge. It becomes explicit, shared, and reusable.
Skillsync helps companies find engineers based on their code. It creates structured skill profiles of developers based on their open source contributions on GitHub. Using a Cursor-like interface, companies can search for specific capabilities like "deployed custom neural nets on edge" then qualify, shortlist and engage with engineers already building in their domain.

We make running services on Kubernetes as easy as Heroku, but on your cloud and with all the flexibility and power of Kubernetes. Companies use Skyhook so that they don't have to hire dedicated infrastructure engineers. Although 50-70% of organizations have already adopted Kubernetes, most developers agree that it is too complex and difficult to manage. It is intended to be extremely flexible in order to solve pretty much everyone’s needs, but it can take a ton of work and many auxiliary tools to get there. As companies grow, they spend a lot on DevOps or Platform Engineers that try to reduce the burden on developers by gluing together all the 3p tools via custom internal tools. We are building an “internal developer platform” out of the box, with best practices and golden paths for building and operating services on Kubernetes. We do the research on the latest and greatest tools in the extremely vibrant ecosystem, and automatically integrate for you the tools you want to use. We operate on our customers code and in your Cloud environment, so they never locked in and never restricted, as is common with classic PaaS offerings. If you prefer a fully hosted environment like Heroku, Fly or Vercel, we’ll host a cluster for you and offer you a one-click migration to your own cluster when you want.
