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.

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 builds AI agents that generate the reports banks and financial institutions file with their regulators. Before any number lands in a filing, our verification engine checks it independently. Every line gets recomputed from ledger records and checked against a versioned rulebook, and wrong outputs go back to the agent with the reason, like compiler errors. They don't ship. We met our first year studying computer science at the University of Waterloo, and interned at Meta, Optiver, and BitGo, places where one unverified number in a filing has real consequences. At BitGo, attestations proving customer assets matched the ledger were assembled by hand every period. At Optiver, daily regulatory numbers were rebuilt manually because nothing downstream took them on faith. Today a controller pulls data from the core system into Excel and maps it to the report line by line. By the regulators' own estimate, one quarterly filing takes weeks. The software banks buy for this validates formatting, not truth: a loan mapped to the wrong schedule line passes every check it runs, and an executive personally signs the result. This is hard because verification has to be independent of the model doing the work. Recomputing every number from source records is the only check a regulator or auditor will accept, and it's why DeepSeek v3 with our engine beats GPT-5 on public reporting benchmarks. Every regulated institution files these reports, forever. Whoever proves the numbers owns the layer the filings, the audits, and eventually the books themselves depend on. We build it, and the agents that run on it.

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.

Truffle is the first AI-native operating system for the hospitality 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. Truffle 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-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.

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.

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.

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.

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
