Logical is a desktop AI that acts as a proactive and largely promptless copilot, designed to reduce the friction of using AI for everyday tasks. It transfers context across apps, and allows taking action on many apps with just a few clicks. Logical can assist with drafting emails, writing docs, noting meetings and can even automatically detect action items. Need to prompt? Logical can understand intent in much fewer words than a regular chatbot. Plus, user data is never sent to Logical servers. Logical is the AI resurrection of Clippy, but actually good.

Logical Health is on a mission to reclaim $500B (2% of the US GDP) in avoidable healthcare waste by transforming how insurance policies are structured and interacted with. To do this, we spun out of a Stanford Research Lab and formed Logical Health. We are a team of health professionals, Stanford MBAs, Google and Meta tech leads. We even have a former CEO of Blue Cross Blue Shield as one of our advisors. Our unique insight is to ground AI with a math rules engine to produce fast and precise insurance coverage answers. We have a proprietary system to produce this math engine by converting health insurance policies using declarative programming. If this sounds complicated, feel free to ping us to learn more. This tech is proven to work and already saved one of the largest insurers $16M/year. Our wedge into the massive healthcare market is customer service. Next, we’ll bring the same high-precision coverage answers to prior authorization, claims processing, and plan design.

LogisticsOS provides route optimization and fleet dispatching algorithms as services to let any last-mile company offer same-day and next-hour delivery.

Loop Health is a new type of healthcare provider in India combining high-quality primary care and insurance for employers. Employees get unlimited primary care visits at our asset-light clinics, alongside traditional hospitalization insurance. During YC, we grew from 0 to $85,000 ARR with 200% MoM growth. We serve 22 companies and 5500 members across Pune. Employers pay us $15/member/year and we make an additional $25 on prescriptions, lab tests, and hospitalization referrals. Our total gross margins are 70%. 200MM Indians are covered with employer-funded health insurance, representing a $8 billion dollar market opportunity, growing at 27% CAGR. Indian employers are dissatisfied with their health benefits today because insurance in India only covers hospital stays, not doctor visits – and only 8% of their employees will ever use the benefit in the year. With Loop, employers can offer a more engaging health benefit that includes doctor visits and telemedicine, alongside traditional hospital coverage, for about the same price. Because their employees have better access to doctors, we can also offer lower insurance premiums.

GTM teams are drowning in disconnected data—Salesforce, Stripe, Mixpanel, Gong, Slack, and email. The result: leaders can’t trust dashboards, data teams get buried in ad-hoc requests, and deal teams burn days stitching context instead of driving revenue. We have built Lopus Probe, an AI-powered GTM research platform that unifies structured and unstructured data into one governed workspace. Powered by an agentic semantic layer, it understands your company definitions, joins CRM + billing + product + transcripts safely, and delivers fast, explainable answers with lineage back to the source—turning every question into a lever for growth. Engineered by Lopus AI, the GTM weapons lab.

Lotas is building Erdos: a secure, AI-native IDE for data science. Cursor is excellent for software development but it lacks data science-specific tools that are critical to a data scientist’s workflow. Lotas is closing that gap. For our first product, we built Rao: an AI coding assistant into RStudio — an IDE used by up to 5 million data scientists and statisticians who use the R programming language to analyze data. Rao could read, write, and edit code while understanding the user's context (codebase and environmental variables).
