Salus logo
Your agent processed a refund without looking up the order, costing you thousands. It emailed your top lead using hallucinated data, ruining the deal. You only found out three hours later from a support ticket or an angry email. Evals, output scoring, and observability are all necessary - but all reactive. They can reduce the likelihood of these problems occurring, but there's no solution that inspects an action as it’s about to execute. Salus does that. If you are deploying agents and want to improve their correctness we’d love to help. Book a demo on our website, and we can onboard you immediately. We can get you started with just a pip install and a few lines of code.

Kita Technologies logo
Kita is the document intelligence platform that powers modern underwriting in emerging markets. Lenders use Kita to process messy, unpredictable financial documents such as bank statements, e-wallet records, payslips, and business income files, turning them into structured, verified signals that fit directly into underwriting workflows. In Southeast Asia and other emerging markets, the most important financial information rarely arrives in clean or standardized formats. Income is fragmented across employers, e-wallets, payment channels, and document types. Even when lenders have strong internal systems, the variability of these inputs makes it difficult to consistently and quickly extract, validate, and interpret the data that matters for credit decisions. As a result, underwriting remains slower and more complex than it needs to be. That is why we built Kita. We believe lenders deserve technology that adapts to the realities of emerging markets rather than forcing those realities into rigid templates. Kita ingests, validates, and structures borrower-submitted documents into underwriting-ready data. The platform is fully customizable to existing lender workflows; teams define the signals they care about, while Kita handles normalization, validation, and anomaly detection behind the scenes. Our team is composed of Stanford engineers and operators with experience in AI and computer vision systems, fintech, network security, and emerging-market infrastructure. We are backed by Y Combinator (YC W26) and advised by industry leaders who have built and scaled data-driven products globally. Join the lenders modernizing their underwriting at www.usekita.com.

Traverse logo
Reinforcement learning environments for long-horizon agent journeys. We are building the infrastructure to automate economically valuable work, starting with software engineering. Why software first? It's the most verifiable and deterministic domain that exists today. Tests either pass or fail. Builds either succeed or break. This makes it the ideal starting point for training agents on real outcomes rather than human demonstrations. Software also creates a natural flywheel where AI that can write code can help improve its own training infrastructure and accelerate its own development. When AGI arrives, the bottleneck will be high-quality training data for every industry where valuable work takes place. You cannot build an RL environment for legal research, medical diagnosis, or financial analysis by scraping the internet. Domain experts are required because they understand the workflows, edge cases, and accumulated knowledge that makes each field what it is. Our approach is to pair world-class domain experts with world-class ML engineers to build training environments that simply cannot exist without that combination of talent. The path to general intelligence is to traverse through every domain where work happens.

Canopi logo
Canopi is the workforce credential infrastructure for supply chain, logistics, and transportation operators. We help organizations keep safety sensitive workers compliant, ready, and on the road by centralizing licenses, certifications, and training in one system. Today, most carriers, 3PLs, and operators still track CDL status, hazmat training, equipment certifications, and safety credentials across spreadsheets and disconnected tools. That creates blind spots, operational delays, and unnecessary compliance risk. Canopi replaces that chaos with a unified, AI powered platform for real time credential intelligence. Customers get a single view of who is cleared to work, what is expiring, where they are exposed, and what needs attention next. Our platform brings together credential tracking, expiration monitoring, proactive alerts, risk insights, audit ready reporting, and a dedicated Auditor Workspace that makes audits and customer reviews a non event. Built for regulated, high stakes environments, Canopi helps operators protect uptime, stay compliant with confidence, and prove readiness to regulators, customers, and partners.
