Coach is the AI sales coach for in-person sales teams. Reps record every meeting, and our AI figures out what your best closers do differently, then coaches everyone else to do the same, with precise, personalized feedback after every meeting. Managers finally see 100% of what happens in the field: Coach flags who's stuck and why, so they only step in when it matters, and can coach 5× more reps. And every meeting feeds one sales brain, so leadership finally gets answers to the questions that used to be guesswork. They finally see the game of their team not just the scoreboard. Our bet: in the AI era, in-person sales will only matter more. It may end up being one of the last truly human jobs. Our conviction: any motivated rep can become a great one, meeting after meeting. The results so far: +32% average lift in conversion rate. COΛCH, post-game video analysis for field sales reps. YC S26

Executor.sh is an MCP gateway that allows you to sign in once to all of your integrations and use them with any client. We enable you to connect your agents to anything (MCP, GraphQL, OpenAPI) so regardless of what you're trying to connect agents to you're able to. If you're trying to scale agents to access all of your production services, data, etc, you need Executor as a unified management layer.

When global shipping breaks, companies pay three times: the emergency freight bill, the commitments they miss, and the weeks their teams lose to firefighting. Ekho customers skip all of it - they get days to weeks of warning and the cheapest/fastest move on each shipment and PO. Everyone else reacts to the same news at the same time; Ekho customers act before it.

TL;DR: PokerClubHub is the first licensed poker club platform. We protect players’ deposits and allow anyone to open their own poker club and make money. Regulated online poker sites like PokerStars have open player pools and thus are full of pros and bots, driving players to unregulated private clubs. Existing poker club platforms like ClubGG have no payments processing. Players deposit with a club owner by sending them crypto for play-money chips. In theory, these chips can be exchanged back for money. However, players can get scammed and withdrawing takes ages. This model is also broken for honest club owners who have to manually process hundreds of deposits a day. They lose out on rake when they sleep and struggle to get players to trust them. On PokerClubhub, players deposit with PokerClubHub, not the club owner. We handle all deposits and withdrawals for the club owner, saving them time and increasing their earnings. We pay the rake (if any) to club owners as affiliate fees. We hold the same gaming license as BetHog (built by founders of FanDuel) and Nexa Poker (part of World Poker Tour). Player deposits are secured using Fireblocks. You can also play rake-free games with your friends and acquaintances on our platform. We ensure that everyone pays up.

AI apps such as ChatGPT and Claude have become part of everyone's daily workflow, but they introduce new security risks that traditional security tools weren't built to handle. Security teams at companies from startups to Fortune 500s, are struggling to keep up. Traceforce gives a company’s security team visibility of how AI apps are being used across company’s devices, and the ability to detect and prevent security breaches and unsafe actions as early as possible.

Rapidfolio helps banks and fintechs fully automate back-office workflows like fraud investigations, KYB/KYC and loan underwriting, with accuracy and auditability.

Assemble accelerates IT teams by performing development work inside core enterprise systems like ERP, CRM, and HRIS. Our agents help IT teams scope dependencies, build logic, and validate changes across your systems.

If your team uses Cursor, Claude Code, or Codex to ship, you've felt it: the AI is great at writing code, mediocre at debugging it. When something breaks in prod, you're back to grepping logs, adding console.logs, redeploying, and hoping the AI's guess is right. HyperProbe fixes this. Your coding agent dynamically drops non-breaking probes into your running services, straight from your IDE. When a probe fires, HyperProbe captures and sanitises the exact variable state, feeding your agent real evidence instead of flat logs. This fixes prod incidents in minutes from the exact same window where agents write code, without ever redeploying to add a print statement. Under 1% CPU overhead. Automatic PII redaction. Built for backend teams shipping AI-written code today. Install in 60 seconds, see your first investigation in 10 minutes. That's why we call HyperProbe the runtime data layer for AI-native software.

Trope is the AI-native system integrator for ERPs. Today, that means the Microsoft ecosystem: we implement Dynamics 365 Business Central, move companies off retiring systems like Dynamics GP and NAV, and run custom AI agents inside the ERP as a managed service. Agents carry the mechanical work: configuration, data migration, test cycles, and documentation. It is like having a consultant, project manager, and developer working 24/7. Principal consultants who have delivered 200+ implementations across 20+ years in ERP systems scope the work and sign every gate, so customers get a fixed price quoted at scoping and a go-live measured in weeks, in an industry that runs six to eighteen months on hourly billing. After go-live, the agents stay. Reconciliations, exception monitoring, reporting, and collections run as a managed service, reviewed against KPIs agreed at scoping. The delivery engine is built in-house.

screenpipe record and learns how you work and turns it into a searchable memory, documents, and AI agents. Data is stored on your device or where your team choose, open source.

LemonLime enables any business to deploy custom AI automations in minutes.

Prized lets non-engineers build, deploy, and share secure internal tools with AI, no engineering required. You don't need to know where the data lives, what APIs to use, or which connectors you need. Just describe what you want (a customer lookup, a dashboard, an approval flow), and Prized builds the tool on top of the right company data inside a governed boundary. The people who feel the pain of missing internal tools most are non-engineers. They understand the workflow best but are blocked by the software layer, so they wait on engineering, duct-tape spreadsheets together, or increasingly rip company data into Claude Code and Cursor with no thought to permissions, sharing, or governance. Prized makes security the default, enforced in the infrastructure rather than left to whoever built the tool. Each tool gets access only to the tables and integrations it was explicitly granted, credentials are workspace-scoped so tools can't cross org boundaries, and outbound calls go through a controlled layer. As an employee builds and shares, a teammate forks it and re-points it at their own data, and over time the company builds up a library of governed tools it actually owns. Hudson was founding engineer at Gander (F24, acquired by Archer), then full-stack at Suno. Marinos studied CS and ME at Stanford and was on the same Gander team.

Definite is where finance teams build everyday back-office agents on one live model of their books. We plug into your ERP, ledger, payroll, and payments read-only and compile everything into one clean model that stays current as money moves. Your back-office team then builds agents on top in plain English. We never write back and we never move money. The agents are yours, the plumbing is ours. We met in first year computer science at Waterloo and interned at Meta, Optiver, and BitGo. At Optiver they ran an n8n hackathon and the interns automated basically nothing. It couldn't talk to the systems that mattered. When we pitched banks and fintechs on agents, they kept telling us the same thing. The agent isn't the hard part, getting clean data out of their systems is. Right now, automating anything in a back office means engineers hand-stitching data from a dozen sources in different formats on different schedules. Tools like n8n and Workato assume your data is already clean and joined. In finance it never is. So the teams with the most repetitive work and smallest budgets get nothing. The hard part is the compiler. Every source gets cleaned, matched, and joined into one live model of transactions, invoices, vendors, and payments, and it has to stay right as money lands every day. Everyone throws engineers at this. We're doing it once so nobody has to again. Every back office is getting agents eventually. Whoever owns the data they read from owns the thing all of them depend on, and eventually the books themselves. That's what we're building.

Whitespace is the AI operating system for wholesale distributors. It connects to their systems and inboxes to build a living model of their business, then deploys self-improving AI agents to automate work like inventory planning, customer support, and order entry.

FlowManual is the all-in-one AI bidding and purchasing platform for both general and MEP construction contractors. Built by two engineers and Harvard dropouts, FlowManual automates the buying process during pre-construction. With FlowManual, specialty contractors win more work while general contractors deliver at higher standards.

Poth is an agentic research platform that connects to your company data, creates hypotheses about what might be causing problems, and validates them using both existing data and adaptive user feedback.

Marble is the first AI-native operating system for the restaurant back-of-house. Restaurants, cafes and bars still run on a patchwork of disconnected point solutions, spreadsheets, clipboards and tribal knowledge, which costs the industry billions each year in stockouts, food waste, and lost profit. Marble replaces that entire stack with one system. Computer vision and voice AI capture real-time inventory levels 90% faster than manual counts, ML models forecast item-level demand at 97% accuracy, and AI agents run dozens of end-to-end workflows autonomously, from procurement and invoice reconciliation to scheduling, food prep, menu engineering, and more.

Care GP is building AI agents to run operations for primary healthcare clinics

Enjamb runs the entire drug program for biopharma teams, from discovery to FDA approval. Pharma runs on decades of closed legacy systems like Benchling, Veeva, Medidata, and SAS, with no AI layer and no MCP to connect agents to them. So we built that connection layer in one platform. Our agents run on top of their existing systems and data, with no migration, and do the work across the whole program: clinical evidence, trial design, statistical programming, and regulatory submissions. In just 3 weeks since launch, we're already being used by 500+ employees at top pharma companies, including Johnson & Johnson, AbbVie, Bristol Myers Squibb, Merck & Sanofi.

Describe an experiment in plain English, and Infera turns it into a validated, instrument-ready run across the equipment your lab already uses. Infera handles the protocol logic, vendor-specific scripts, data, inventory, and institutional knowledge in one system. An AI-native compiler for the lab: one system from intent to execution.

Sidekick is an AI assistant for frontline manufacturing workers. Sidekick lets workers text problems, photos, or voice memos in any language; it answers from the company's own documents, creates and routes the work order, and syncs with software the company already runs. Sidekick captures the tribal knowledge in veterans' heads - the know-how that usually walks out the door when they retire - into a searchable knowledge base the company owns. No app, no login, works on any phone.

Enterprise software implementation is broken, and it has been for decades. Every rollout, whether it's a traditional ERP or a new AI system, requires months of manual integration, configuration, and tuning done by armies of system integrators and forward-deployed engineers. Lab0 builds agentic systems that automate this layer, compressing months-long implementations into weeks.

We build human foundation models. Our first family of models powers lifelike avatars that interact with users in real time, enabling AI agents and applications to go beyond text and voice with just a few lines of code. State-of-the-art realism with ultra-low latency at scale.

Saffron allows companies to quickly evaluate how well software engineers use AI to code. The way engineers write code has fundamentally changed, but the way companies evaluate them hasn't. Saffron gives teams full visibility into how candidates use AI agents to build, debug, and ship real features on an actual codebase. Saffron was founded by Robert Chondro (formerly MIT and Jane Street), Jerry Yao (Stanford and Jane Street), and Kazuma Choji (Harvey Mudd, published in NeurIPS and ICML), and is backed by Y Combinator (P26) and Afore Capital.

As the nature of work and society continually make it harder for the younger generation to make lasting connections, afterfive is building offline events, and eventually spaces, for irl human interaction.

10x Science develops frontier AI models with deep memory to redefine how scientists understand and engineer biology across the life sciences, starting with drug development. AI-powered drug discovery is flooding the pipeline with new candidates faster than ever. But before any of them can advance to the clinic, scientists must deeply characterize the protein therapeutic to understand whether it will work. Today, that process takes months of manual, error-prone analysis that cannot keep pace with discovery. Our AI-native platform automates it, giving drug developers the confidence to advance the right candidates and stop the wrong ones early. We have strong commercial traction with enterprise pharma customers. Our founding team built the field of next-generation protein characterization out of Carolyn Bertozzi's Nobel laureate lab at Stanford. Collectively, we have 18+ years of collective domain expertise, 47+ scientific publications, and a 2x YC Founder. We move at the highest velocity and are positioned to lead the next generation of modern AI development in the life sciences.

Corvera (YC W26) is the context layer for AI-native CPG brands. We help brands unlock the full potential of AI by making their unified data legible to any AI tool via MCP.

Moss is building the real-time semantic search runtime for conversational and multimodal AI. Our system enables voice agents, copilots, and chat interfaces to retrieve, reason, and respond in sub-10 ms, delivering the responsiveness that makes AI interactions feel truly natural. If you’ve ever built a conversational or voice AI product, you’ve felt the lag. That moment when an agent pauses and the illusion of intelligence breaks. The bottleneck is almost always retrieval. Each query hops across networks and databases, adding delay and cost. Moss eliminates that gap by keeping retrieval close to where the agent runs. Moss runs natively across browsers, mobile devices, and servers with an optimized vector index built in Rust and WebAssembly. It enables teams to build AI products that feel instant, contextual, and adaptive. The experiences that sustain engagement and unlock new kinds of interaction. For our customers, this translates into tangible business value: stronger user retention, higher conversion, and entirely new product categories made possible by real-time understanding. Moss is already powering production pilots across voice AI and developer platforms, achieving sub-10 ms retrieval and 70–90% token savings compared to traditional pipelines.

Everything is cached and reproducible, and you can send the same surveys to human respondents to validate results in the same interface.

Hyperspell is your Company Brain. AI agents are brilliant and clueless. They ace any test and still have no idea how your company works. Hyperspell connects your tools and synthesizes documents and conversations into a live, permissioned context graph. Any agent can read from it and write back to it like a filesystem, with every fact traced to source.

Aside is an AI browser that completes real work across the websites you already use. It can sign in through your browser, work inside email, dashboards, internal tools, docs, and spreadsheets, and keep going when a task takes minutes or hours. Unlike agents that depend on integrations, Aside uses the web the way you do. Browsing history becomes local memory, so it knows which tools and context matter. Its password manager lets agents autofill credentials without exposing secrets to the AI. Sensitive actions like payments, posts, and messages wait for your approval. We achieved state-of-the-art on agentic browsing benchmarks, surpassing OpenAI and Anthropic's result- Aside ranked #1 across Mind2Web, Odyssey, bu-bench-v1.

Primer is an AI agent that sells, onboards, and supports users automatically through live, personalized walkthroughs.
