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.

Ruma Care logo
We help infusion clinics get every biologic approved and paid for. Biologics are expensive specialty medications that cost $80K/year and are very hard to access.

First, Ruma maps each drug to each payer's formulary rules and required forms. We then automate the form-filling for prior authorizations. Lastly, we enroll patients in copay assistance programs, all in a singular workflow and platform.

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.
