ritivel (YC W26) is an AI-native workspace that helps pharma regulatory teams draft FDA submissions 12x faster.
Every month a drug is delayed costs pharma companies ~$45M in lost revenue and more importantly, delays treatment for thousands of patients who need it. Regulatory teams spend weeks manually synthesizing thousands of pages of clinical data, hunting through SharePoint folders for the right documents, and drafting submissions like CTDs, CSRs, INDs, and BLAs.

As a cinematographer, Koh Terai knows great video production doesn’t come from endless prompts — it comes from a well-run set: intentionality, collaboration, and control.
So Koh and Long built Martini to give filmmakers an environment to direct and shoot their generative AI films.
They first shared Martini with a few friends. Then more. Today, over 200 films have been made with Martini, aired as TV commercials, displayed as artwork, and gone viral online.
If you’re a filmmaker, studio, or cre ...more

Ruma Care is solving prior authorizations - starting with the most complex specialty medications.
Biologics are expensive medications that cost $80-$150K+ per year per patient. 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.
These specialty medications are denied by insurers at a rate of 37% each year because of their high cost. When they are denied, providers don’t g ...more

Kyten (YC W26) designs and manufactures custom aerospace-grade battery packs for defense applications.
100,000+ drones, submarines, and satellites are being built in the US, but the legacy supply chain doesn't think like a modern manufacturer; they can't keep up.
During their six years at Starlink, Cooper McBride & Lucas Maddox put 5,000+ battery packs into space. Now, they're bringing rapid development and volume production of aerospace-grade battery packs to the entire industry.

Poetiq is a startup founded by former DeepMind researchers, Shumeet Baluja and Ian Fischer, that recently achieved a major jump on the ARC-AGI benchmark by layering a recursive self-improvement system on top of Gemini 3.
In this conversation at NeurIPS, YC's Francois Chaubard sat down with Ian Fischer to find out how Poetiq is increasing performance using prompts and system design alone. They also explore recursive self-improvement, benchmarking progress toward AGI, and why automating prompt en ...more

The most regulatory man on earth uses Rhizome AI to get FDA approvals on the first try.
He dives into the ocean, not PDFs on a website.
He reads jaguars in the forest, not regulators in a meeting.
He knows what the FDA thinks. With some help, you can too.
Ask Rhizome a question. It reads up to 1,000 documents and gives you an answer where each statement has a citation.
Be compliant, my friends: https://rhizomeai.com/
Congrats on the launch Chetan Mishra!

Congrats to the team at Poetiq on their $45.8M seed!
You don't always need a bigger model to get better results. Co-founders Ian Fischer & Shumeet Baluja and their team are proving that vision at Poetiq by accelerating recursive self-improvement.

Orthogonal (YC W26) is building a simple way for AI agents to discover and pay for APIs.
AI agents are about to become the biggest consumers of APIs, but today’s API ecosystem was built for humans. Agents have to manage accounts, API keys, auth flows, and billing across dozens of services, which makes using paid APIs slow and unreliable. As a result, many agents can’t access the tools they need, and API providers leave money on the table.
Orthogonal fixes this with a single MCP or SDK that giv ...more

Bidflow is an AI copilot to help electricians compete for more jobs.
Electrical contractors are constantly in bidding wars to find new jobs to work on. The bidding process can take anywhere from a few hours to months to complete, with no guarantees of winning the project. This process requires sifting through large documents, analyzing circuit diagrams, and entering tons of data on legacy software programs to get an estimate for how much a project will cost. If the estimate is slightly off, it ...more

Mendral (YC W26) keeps your CI green and fast by finding what broke, why it broke, and helping ship the fix.
Teams lose huge amounts of time to flaky tests, slow pipelines, and recurring build failures. Most tooling tells you what happened. Engineers still have to dig through logs, rerun jobs, and patch brittle CI over and over. With more code being produced than ever, that drag only gets worse.
Mendral watches your CI/CD, diagnoses failures, flags flaky tests, finds slowdowns, and opens PRs w ...more

Voxel Energy builds data centers coupled with onsite power generation, enabling data center commissioning in months, not years.
$3 Trillion in data center projects are slated for construction by 2030, yet half may never be built due to power constraints. Voxel bypasses the gridlock throttling the American AI boom and unlocks billions in pull-in revenue.
Voxel leverages the ever-expanding pool of second-life EV batteries to build energy storage capacity into the hundreds of megawatt-hours and b ...more

CatchBack Cards is an iOS and web platform for maximizing the thrill of collecting Pokemon and Sports cards.
The trading card market is massive, fast-growing, and very large in transaction volume. Globally, physical trading cards (sports, Pokémon, anime like One Piece, etc.) represent a $20B+ annual market, growing at double-digit rates (~10–15% YoY) even after the pandemic boom. Beyond retail sales, billions of dollars move through the secondary market each year via graded cards, private deals ...more

EigenPal automates your document processing workflows with AI.
Every large company has teams of people doing repetitive document processing. It's grueling work and mistakes are costly.
Here's the problem: LLMs finally work well enough for production document processing (~95%+ accuracy), but enterprise ops teams can't deploy them. Why? Legacy RPA tools treat AI like another deterministic API call - no eval framework, no drift detection. New platforms are missing evaluations and are hard to ope ...more

Shofo (YC W26) is building the Common Crawl for videos.
AI labs need massive video datasets, but high-quality, segmented video data is hard to access.
Shofo is assembling the largest index of short-form videos. They build complete pipelines that collect, segment, sanitize, and label videos from across social media to curate custom datasets for AI labs.
For example, if a lab needs 50k cooking videos featuring hand-object interactions, Shofo queries their index, runs it through their labeling p ...more

LegalOS (YC W26) is the AI-native immigration law firm that delivers visa petitions in as little as 48 hours, not months—pairing AI with highly experienced immigration attorneys.
Immigration law is broken for startups. Traditional law firms take 8 weeks to prepare a petition, charge up to $35k per visa, and give customers zero visibility until it's too late.
Quality is inconsistent- leading to RFEs, delays, and denials. The stakes are brutal: one denial can force a founder to leave the country ...more

Kita (YC W26) turns messy financial documents into fraud-checked, predictive risk signals that power lending in emerging and underserved markets, starting in Southeast Asia.
In places like the Philippines, bank APIs often do not exist. Lenders are forced to rely on “noisy” documents such as bank statements, payslips, and financial statements to understand a borrower’s history. Today, that leaves them choosing between slow, expensive manual review or brittle legacy OCR that breaks on real-world ...more
