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.

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.

Korso builds AI agents that handle the operational work manufacturers still do manually, including processing RFQs, following up on quotes, coordinating with suppliers, and keeping production on track when things go wrong. Our agents plug into your existing ERP and CRM, understand your workflows, and act on your behalf: triaging incoming requests, chasing delayed orders, notifying customers, and escalating when human judgment is needed. We built Korso around the reality that enterprise systems cannot afford mistakes. Every agent action passes through verification layers, tools are scoped, and critical operations go through dry-run validation and secondary review. Full audit trails mean you can see exactly what was done, why, and when. Most AI automation breaks down at the ERP integration layer. Korso's orchestration is built for the messiness of real manufacturing systems, with long-running workflows that span weeks and checkpointing that never loses progress. Instead of replacing your systems, Korso makes them work harder, so your team spends less time on coordination and more time on the work that actually matters.

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.

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.

Companies spend up to $50k to file and maintain a single patent over its lifetime, but once it's granted, they let it collect dust. With Patent Watch, you can start turning your patent portfolio into revenue in 10 minutes.

Specific builds audio and enterprise datasets representative of work inside real-world businesses. The next frontier of AGI is bottlenecked by data that is hard to access, and we make that easier.

OnDeck is the infrastructure layer that makes Vision Language Models accessible and scalable for enterprise. We let organizations instantly find any object, behavior or event, in any footage, without needing to train a model or collect any training data. The Pain: Creating vision models usually takes months: collecting training data, training, then deployment. Worse yet: + it’s often impossible to get enough data for a specific task, and + even the best cv models struggle to generalize across diverse camera setups, workflows and environments. To overcome these blockers, we bet early on the power of VLMs and built a vision engine that can generalize across any task and doesn’t need any training data. We published a NeurIPS workshop paper showing our new methods with VLMs beat traditional CV even at niche tasks. Our current customers include: - National Defense Organizations - Robotics Research - Security cameras - Behaviour analysis for port monitoring - Off-shore oil & gas monitoring

Char is a daily notepad that finishes your todos for you. Type a checkbox, and an agent picks it up — researching, drafting, or scheduling on your behalf. Stay in command. Char does the work.

Serafis is building super-intelligence for financial markets. We mine petabytes of unstructured data to identify narrative inflections before they become consensus.

Frizzle uses AI to grade handwritten math assignments for teachers and transform them into rich analytics and differentiated assessment to help personalize instruction for every student. Teachers spend over 10 hours a week or 25% of all their work grading - Frizzle does it in minutes. Frizzle is the most valuable piece of software for teachers ever, as it eliminates the most time-consuming part of their workflow so they can focus on teaching. Frizzle shifts education from waterfall to agile learning. Instead of waiting for end-of-unit tests to discover gaps, teachers get continuous, real-time insight into student thinking from everyday work. Feedback becomes immediate, instruction adapts weekly, and learning iterates (measure, adjust, improve) so every student progresses faster with less teacher burnout. Frizzle was named an official White House AI Education Partner alongside OpenAI and Meta: https://www.whitehouse.gov/edai/. Frizzle was co-founded by Abhay Gupta and Shyam Sai, who met in high school over 10 years ago.

When enterprise agents fail in production, the conditions that caused the failure are critical: user state, data, tool calls, and context. Without a way to recreate these conditions, teams can't fix what broke. Playgent provides infrastructure to create high-fidelity sandbox environments for AI agents. Our environments come packaged as a single MCP url where tool calls are mocked, authentication is abstracted away, and test data can be initialized via natural language or JSON specifications. Teams can use Playgent to reproduce production failures in safe, scoped environments that accurately reconstruct state. Finally, export runs as OTel traces from Playgent's environment to plug directly into your observability tools or RL pipelines.

We use AI to help electricians speed up the time it takes to submit a competitive bid to a job. We do this by scanning complex CAD drawings and 10X-ing the time it takes to estimate a job. This involves using vision models to read and count complex symbols in large PDFs, which typically take hours (sometimes days) to do precisely. Every missed symbol can cost thousands, and our AI can count to 99% accuracy.

Epicenter is an ecosystem of open-source, local-first apps that share a memory. We store all your work—notes, transcripts, chat histories—in a single folder of plain text and SQLite. Every tool we build shares this memory: your text editor, personal assistant, etc.. It's open, tweakable, and yours. Grep it, open it in Obsidian, host it wherever you like. The choice is yours. Our vision is to build a personal workspace where you own your data, choose your own AI models, and replace siloed apps with open, interoperable alternatives. All while preserving authenticity and being free and open source. ❤️

Floot lets non-coders & entrepreneurs build real web apps that actually work. We’re taking a new approach by building everything from the ground up for AI. ✨ Try building an app at floot.com Existing AI app builders fall short of enabling non-coders to build real, serious apps. They often: - Break down when building anything more than a prototype or toy app - Have non-coders stuck with errors they don’t understand - Require non-coders to handle multiple services designed for developers (e.g. for backend, database, hosting, etc) The fundamental problem: these AI app builders just cobble together existing developer tools and slap AI on top, but these tools were designed for humans and not for AI. The result? Non-coders get excited, start building, hit a wall, and then abandon their projects. Floot is purpose-built for AI. Our secret sauce: 1) Instead of reusing a coding framework designed for humans, we created a specialized framework that dictates how AI should write code and how the code runs on our infrastructure. This allows us to enforce best practices, detect errors earlier, and give the best feedback to the AI. As a result, Floot can write better code and fix issues more effectively. 2) Floot has the entire tech stack built-in (backend, database, hosting, etc) so building and managing an app feels seamless, especially for non-coders. And because we control every layer of the stack, we can optimize each layer for AI-first coding. Because of this, non-coders can get more done with less time and prompting. They can finally build serious apps that work, instead of getting stuck in frustrating error loops and then abandoning their projects. We also built a highly scalable hosting system directly on AWS so Floot apps can handle real traffic and business demands. This means non-coders can build, deploy, and scale their apps on a single platform seamlessly. Plus, Floot is really fun to use! Try building an app at floot.com

Stockline is an AI-native ERP for food wholesalers. Our agents eliminate human labor for repetitive tasks, starting with order entry. Our goal is to replace clunky software with the next generation of ERPs, built with AI employees at their core. Team is 2 Polytechnique alums who dropped out of Stanford and MIT. Mariem is daughter of the fish industry and Moncef started coding and building softwares at 13.

Plaintiff-side law firms compete in some of the most expensive search ad markets to acquire high-intent leads, but the path from click, call, or form fill to signed retainer is still fragmented. Disconnected intake workflows, slow response times, and disconnected spend-to-case data makes it hard to know what is actually working. Mimos automates their growth and intake playbook: 1. Generate Qualified Leads: Our agents manage Google Ads, Local Services Ads, Google Business Profile, and other high-intent acquisition channels. 2. Convert Faster: Every lead flows into a CRM built for intake, triage, follow-up, and handoff from inquiry to signed retainer. 3. Close the Loop: We connect spend, lead source, intake actions, and signed-case outcomes so firms know what to scale, pause, or fix. The result: more qualified leads, less wasted spend, and more signed cases.

Certus AI is replacing the restaurant phone line with Voice AI. Restaurants lose up to $100,000 per year per location from missed calls, lost orders, and abandoned hold lines. Staff are overwhelmed. IVRs frustrate customers. Call centers are expensive and impersonal. It’s 2025. Guests don’t leave voicemails or wait on hold. They just move on. Certus is an AI voice agent built for restaurants. It answers every call, 24/7 — taking orders, processing deliveries, booking reservations, upselling, and handling complaints in English, Spanish, French and more. Certus is built to manage the phone line end to end, from the customer call to the restaurant tech stack, with zero human intervention required. It currently integrates with industry-leading systems like Toast, Square, Clover, UberEats, DoorDash, and more. We’re building the voice layer of the modern restaurant — the employee they’ll never fire. We started Certus because we lived the pain. Gurveer (CEO) grew up answering phones in his family’s restaurant and helped operate them, growing from 1 to 11 locations in 7 years. Later, he and Adam (CRO) ran a restaurant growth startup to help others increase revenue, but kept watching clients bleed cash because no one picked up the phone. So we built the solution the industry always wished existed. Until now, this problem was considered unsolvable. But Voice AI has finally crossed the conversational chasm and 72% of consumers now prefer AI over humans as long as it means faster and better service. More importantly, the market is begging for this. The North American restaurant industry crossed $1 trillion in 2024, and it's projected to hit $1.5 trillion in 2025. Yet over $100 billion is still lost annually to missed calls, human error, and outdated tech. As the market continues to grow, so do the losses! Our customers say it best: - “Certus changed my life overnight.” - “We were losing the ability to give great in-house service — the phone was killing us.” - “70% of my business comes through the phone. That’s mine and my 16 staffs livelihood.” - “Before Certus, I used to lose 40 - 60 calls a day…. now my printer just stays printing!” - “I’ve been in the business 38 years. I’ve been waiting for this since then.” Certus is here to fix the $120B phone problem — one call at a time. And in doing so, we’re redefining how the restaurant industry communicates forever, starting with the phone line.
