We're building AI Passport, a personal memory layer that works across AI apps. Every AI product you use today keeps its own memory of you: ChatGPT has one, Claude has one, and every AI-powered app is starting to build one too. None of them talk to each other, you can't see most of what they've stored, and you re-explain yourself to each new tool. AI Passport replaces those scattered profiles with one card you own. Your preferences, history, and goals live in one place, and new information lands in an inbox where you approve or reject it before it's saved. Apps that want to use your context request a pass, which grants them access to only the categories you allow and can be revoked at any time. Receipts show you exactly which app read what, and when. For a user, this means any AI app can know you from the first message. For a business, personalization works in both directions: a storefront can retrieve a customer's taste, sizes, and budget and personalize instantly instead of running an onboarding quiz, and a support organization can keep one memory of each customer across tickets, teams, and agents, so every new case starts with what the company already knows about the person.
EigenPal.com automates your document processing workflows with AI. KYC docs, invoices, claims, shipping forms, contracts, receipts, loan docs - we automate that.

Stratum builds AI agents that clear the U.S. government backlog. Every permit, license, patent, drug approval, and benefits claim in America has to be reviewed by a government adjudicator and the software they rely on was built decades before AI. The result is millions of applications stuck in queues: veterans waiting on disability ratings, families waiting on pensions, builders waiting years to break ground. Stratum replaces that workflow. A reviewer drops in an application, selects the rubric it needs to be checked against, and an agent plans, executes, and reviews the file end to end routing each step to the right model for the most accurate and cost-efficient decision. Hundreds of agents run in parallel in the cloud, with a human kept in the loop to approve and full auditability at every step, so an entire backlog can be cleared in the time it used to take to review a single file. We're rebuilding the entire infrastructure the government runs on both the reviewer side and the applicant side - so filing and adjudication become instant instead of taking weeks. We're Vihaan and Raj, brothers. Vihaan was founding engineer #3 at Cadastral (acquired by Legora) and dropped out of Waterloo to build Stratum. Raj led GTM at Deel, averaging 220% of quota over two years and ranking top 5 of 1,000+ reps globally, and dropped out of grad school at the University of Bath to build Stratum.

We're building the equivalent of 401ks for Pakistan as the first step towards building a comprehensive wealth management platform for the country.
Over 80% of maternal mortalities were preventable with earlier intervention. Currently, doctors miss >50% of moms who have life-threatening complications and wait until labor to start doing manual risk assessments, at which point it's too late. Elythea's proprietary ML models catch life-threatening obstetric complications (like postpartum hemorrhage, preeclampsia/eclampsia, emergency c-section, preterm labor, and more) as soon as the first visit. We automatically analyze relevant demographic and clinical risk factors, flag high-risk patients, and provide evidence-based interventions, giving doctors months in advance to intervene and prevent complications from ever happening. Our global clinical studies have shown that we can catch 3x more complications than clinical judgment 10x sooner.

End Close builds automatic reconciliation for payments companies like fintechs, marketplaces, banks and payroll companies. Reconciliation helps companies track every dollar and resolve every exception, ensuring they have no money loss, can report audit ready financials, and stay compliant. Sean (CEO) spent the last 6 years building the reconciliation org at Modern Treasury (S18), processing a trillion dollars in payments across 40 banks with 99.995% automation. Fast growing companies like Modern Treasury are forced to build a solution in-house or buy a legacy solution. End Close provides a modern reconciliation system that works with a company's existing stack and is managed by AI agents. Exception handling is where 99% of the manual work happens today, payment ops teams spend hours gathering context across various data sources to investigate each ticket. End Close provides an AI ops agent that connects to a company's data warehouse, invoicing platform and payment processors to triage and resolve issues without human intervention. Legacy providers only provide reconciliation for month end close applications. End Close continuously reconciles with developer friendly APIs, allowing teams to integrate real time payments data within their products to create product experiences for customers like faster balance top-ups, instant trading etc. New payment rails and agent-to-agent payments are increasing online transaction volumes, making reconciliation a growing challenge for companies. David (CTO and 2nd time YC founder) most recently built these kinds of high-scale ingestion pipelines when starting and leading error tracking at PostHog (W20), the fastest growing product in the company's history.
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.

Envelope is a banking app with built-in budgeting. It's similar to Mint, Copilot, or Rocket Money, but our app issues you a checking account during onboarding so there's no syncing or flaky bank connections. We are structured to be the primary checking and savings account for our users. We (Josh and Katelyn) are married cofounders who previously worked on Apple Card and the Robinhood iOS app. We started Envelope because we were using clunky tools like the Chase app, spreadsheets, and Mint to run our family finances and realized we could build something better. In the future, you could go set up a Chase account for checking, E-Trade for investing, SoFi for savings, Ally for money market, Greenlight for kid cards, PLUS the Mint/YNAB/Rocket Money to glue it all together + budgeting, or you could just use Envelope. _Envelope is a financial technology company and is not a bank. Banking services provided by Pacific West Bank, Member FDIC. Your funds are FDIC insured up to $250,000 through Pacific West Bank, Member FDIC. The Envelope Visa® Debit Card is issued by Pacific West Bank, N.A. pursuant to a license from Visa U.S.A. Inc. and may be used anywhere Visa cards are accepted._
Eos helps clinics turn their data into actionable insights to identify more eligible patients and early care interventions. We harmonize historical data across all systems to create standardized patient data distributions, acting like a translation layer between different applications. Then we build a centralized index over it: a compressed representation that lets petabytes of raw data stay where it is while allowing us to search and reason across it as one system. Instead of treating the visit or document as an isolated instance, we can look at it as a continuous story. We can predict how a case will resolve, trigger the required approvals and actions, and do so while reducing staff workload and recovering hospital revenue.

EthosX is a decentralized finance platform creating end-to-end financial derivatives on blockchains. No centralized exchanges, clearinghouses, depositories, clearing banks, CSD participants etc. required. We are starting with cryptocurrency options first, with the intention to move towards other crypto derivatives and traditional finance derivatives eventually. For example, one can buy a bitcoin hedging token directly from EthosX without involving any exchange or counterparty and earn profits when the bitcoin price is falling (similar to a put option). It is perpetual and is completely on-chain, end-to-end. It is held as a token in wallets and can be sold/transferred to anyone at any time. At institutional level, using EthosX’s options infrastructure two hedge funds can trade high-value on-chain options with each other directly without involving any banks or brokers with zero counterparty risk and zero settlement risk. We are also providing derivatives infrastructure to other crypto companies who want to use these products as a part of a larger package to their customers. Global derivatives ecosystem is broken. Derivatives trading in traditional finance has way too many gatekeepers and intermediaries. Crypto was supposed to be free of these issues and a solution to all of this, but it is itself getting more and more centralized with disastrous consequences. We at EthosX intend to pick the best of both worlds and change the way retail and institutional financial derivatives are traded world over.

We've built voice agents for the largest work comp managed care orgs and specialist PT networks in the country, making >500K calls annually and accelerating the speed at which they coordinate care. On average, our customers see a 40% increase in workflow completion, 10x decrease in cycle times, and >60% reduction in cost. We think voice agents are the starting point for solving slow and fragmented care coordination in this market. Companies that manage an injured worker's care rely on short-staffed contact centres and archaic methods of info exchange: phone, fax, and email. Every delay along the path of care leads to slower rehab of the injured worker, lower throughput for providers, and higher expense for the insurer/employer.
🦠🤖 We use our computational models to make next-generation antibiotics that outcompete bacterial evolution and precisely target pathogenic bacteria, without harming good microbes or human cells. ☠️ Current antibiotics stop working because bacteria evolve resistance to them. This makes drug-resistant bacteria a looming global health crisis - already killing more people than malaria and AIDS and it is getting exponentially worse 📈. 🧬 Our approach leverages co-evolutionary protein-protein interaction datasets combined with AI to forecast bacterial mutations and create ‘future-proof’ antibiotics, addressing antibiotic resistance before it develops. This changes the game for how frequently society will need to make new antibiotics and how long our new antibiotics will be able to treat patients 👩⚕️. We are a team of biochemists and evolutionary biologists who met at the University of Oxford.
