Ruma Care automates prior authorizations - we’re starting with clinics that administer the most expensive specialty medications. Biologics are expensive medications that cost $80-$150K+ per year per patient, and often need to be administered in specific settings called infusion clinics. Medical providers buy these drugs up front to secure pricing deals and safer inventory - they are reimbursed for the cost of the medications through the patients’ insurance. Because they’re so expensive, these specialty medications are denied by insurers at a rate of 37% each year. When they are denied, providers don’t get reimbursed for the medication and are left covering the costs. Ruma Care solves this so clinics get paid, patients get treated faster, and care teams spend less time fighting insurance. We do this in three ways: 1. For each medication, diagnosis, and insurance combination, Ruma extracts the submission criteria required to get the drug approved by insurers. 2. We pull out the correct forms, then automate the form-filling for prior authorizations. 3. Lastly, we enroll patients in copay assistance programs, all in one workflow and platform. We turn a process that traditionally spans 70+ online portals, disparate paper forms, and manual phone calling into a single, streamlined platform. As we process prior authorizations, our models learn from denial patterns to understand exactly what insurers need to see to get a prior authorization approved.

Your agent processed a refund without looking up the order ID, costing you thousands. You only found out three hours later from a support ticket. Evals, output scoring, and observability can reduce the likelihood of mistakes like these occurring - but there's no solution that inspects and prevents an action as it’s about to execute. Salus does that. We’ve built an API that wraps around your agent and checks its actions at run time, blocking incorrect ones and providing immediate feedback to guide retries. Kevin and Vedant were roommates at Stanford, where they both studied computer science.
Samora runs multilingual voice operations for organizations with high-volume calling without requiring engineering teams, call centers, or AI expertise. Many important tasks still depend on phone calls, including customer support, outreach, follow-ups, screening, and intake. But voice AI often fails in production because real callers interrupt, go off-script, switch languages mid-sentence, and speak in local dialects. Teams also worry about safety and compliance, especially when an agent can accidentally make the wrong promise. Samora solves this with voice agents that sound local and follow strict rules. Samora agents handle inbound and outbound calls, collect information, and update internal systems like CRMs, ticketing tools, and ATS platforms. When a call becomes sensitive or uncertain, the agent hands off to a human. It can also follow up over WhatsApp, SMS, or email when needed. With Samora, teams get: 1. Voice agents that work in real conversations, including dialects and code-switching 2. Strict safety controls so agents don’t make unauthorized offers, discounts, or promises 3. Calls that result in completed actions, system updates, and safe human handoff

Scott AI is the agentic workspace where teams align on spec before any codegen runs. Teams already use multiple coding agents to build. Different coding agents will continue to evolve and have diverse strengths. An engineer will entrust a long-running agent to add dark-mode end-to-end while they pair carefully with an IDE-based agent to land a critical DB migration. These execution agents cannot be the decision layer because they are biased to their own tool, they are not neutral. Scott AI is the neutral, agent agnostic decision layer for the age of multi agent building. Teams will use Scott as their decision workspace to finally ditch google docs and notion as their primary spec alignment layer.
The student information system (SIS) is the core system of record in every K-12 school. It tracks students, attendance, grades, schedules, staff, and more - kind of like the ERP for schools. Legacy SIS providers do just about that, and not much more. School districts layer dozens of tools on top of their SIS to fill in the gaps. Scout is an AI-powered student information system that automates school- and district-wide busywork, from day-to-day operations like attendance tracking to annual compliance reports. Our mission is to help school districts run like high-performing organizations, enabling them to provide high-quality, personalized instruction to every student.

Sourcebot is an open source code understanding platform for massive codebases. We’re used by thousands of engineers in some of the largest companies in the world, including NVIDIA, Red Hat, Wikimedia, and Arista Networks. Understanding code, not writing it, is the primary bottleneck for large engineering teams. For developers, this means onboarding onto complex codebases faster. For AI agents, it means getting the necessary code context to minimize hallucinations and maximize cohesion within the wider codebase. Sourcebot solves this by giving developers and AI agents the ability to regex search across millions of lines of code instantly, as well as ask questions across thousands of repos using any flagship reasoning model. Being open source and on-prem, we can get deployed in enterprises within minutes before other tools even get approval. We met a decade ago at McGill University and have been building together full time for over 2 years. We’ve personally felt the pain of understanding large codebases while working at Microsoft, EA, Ubisoft, Google, and Meta.
