Vaultpay is building a digital banking platform for 30 million smartphone users in DRC and the country's largest agent network. For example, a young Congolese entrepreneur who just won a subcontract with a major mining company can now easily open a personal and business account, receive payments, all from their smartphone, instead of spending hours at bank branches.
Vaya is a consumer travel app for discovering and planning trips, available on the App Store. The company launched as BookMyFlight, a flight search and booking platform that scanned thousands of flights to match an itinerary at the lowest price and let users book directly with the airline in one click instead of filling out airline forms, and has since broadened into trip discovery and planning.
B2B advertising is broken: poor targeting, wasted ad spend, bot traffic, and 3rd party-cookies. Vector helps marketers drive pipeline with contact-level targeting and revealing who's seeing your ads (even if they never convert).
Billions of people need tourist visas to travel the world. We use AI agents to prepare applications, verify documents, secure appointments, and handle the visa process end to end.
Are you trying to run a hybrid sales motion, but Stripe is limiting your ability to bill your custom contracts? Most of us start on Stripe because it’s the default for self-serve. But as soon as you move into Founder-Led Sales, you hit a wall. When an enterprise customer asks for a ramp-up period, tiered usage, or a custom quarterly billing schedule, Stripe’s standard checkout breaks. You end up with "Billing Debt" - a mess of manual invoices, spreadsheets to track renewals, and "hacked" subscriptions that will eventually require a painful migration. We built Veles to be the sales-led billing layer for Stripe. It’s the flexible "Deal Desk" that lets you sell exactly how your customer wants to buy, without the manual overhead. The Problems We Solve (So You Don't Have To): ✅ Complex Pricing & Logic: Whether it’s usage-based, flat-fee hybrids, or "draw-down" credits, if you can dream up the pricing logic, Veles can bill it through your Stripe account. ✅ Custom Deal Structures: Close deals with custom ramp-ups or non-standard terms without manually editing Stripe objects. ✅ Deal Desk & Approvals: Set guardrails so your first sales hires can’t go rogue on pricing. Build a repeatable approval workflow for every contract. ✅ Presentation Flexibility: Your quotes should look as professional as your product. Veles generates quotes as Web Portals, Slides, Docs, or PDFs—all while staying perfectly synced to your backend. The YC Offer: I want to make sure no YC founder is held back by their billing infrastructure. Current Batch (W26): Veles is 100% Free for your entire founder-led sales phase. Focus on hitting PMF and closing your first 20-50 deals; we’ll handle the "Deal-to-Cash" automation. YC Alumni: 50% off the Growth Plan for one year. Scale your sales team and automate your revenue operations without the "Enterprise CPQ" price tag. Stop forcing your custom enterprise deals into rigid billing templates. Sell what the customer wants, and let Veles keep your Stripe account clean. I’d love to hear from anyone currently fighting with Stripe’s "manual invoice" button. What’s the weirdest contract structure a customer has asked you for lately?
Velontra is building a hypersonic space plane that can takeoff from anywhere in any weather. This horizontal takeoff increases launch reliability and enables customers to directly access any orbit. Our air-breathing propulsion system is up to 6 times more fuel efficient than any rocket, and uses oxygen from the air which creates thousands of pounds of additional payload capacity. We have millions in current government/commercial contracts and LOI’s. We have assembled a team of industry experts, government senior executives, and a NASA astronaut. The hypersonic space plane will work by taking off from any runway with a jet propulsion system. Next, it will climb to over 100,000’ and Mach 5. At this point, it will launch a 2nd stage rocket directly into the desired Low Earth Orbit. Velontra is “boldly going where no one has gone before.”

Velum is an open-source firewall for content-level access control across documents, databases, and applications. Admins define policies, and we apply them in real time across your entire stack to control what each recipient sees. Our firewall sits between your data sources and consumers (LLMs, users, vendors), enforcing policies on every request. We understand meaning in text, documents, and databases to detect sensitive information based on your policies, then apply recipient-specific controls without blocking workflows. Create policies in natural language. Teams write rules that define what's sensitive and who should access it, and Velum enforces them consistently across all systems. When authorization changes, we can reveal tokenized data just-in-time for approved recipients, maintaining both security and utility. We integrate directly into your existing infrastructure. For AI workflows, we intercept prompts, responses, and retrievals to prevent sensitive information from leaking into or out of models. For enterprise systems like Salesforce, SAP, or Workday, we extend policy enforcement to exports, reports, and syncs. Velum is designed for scale and compliance. We provide encryption and structure-preserving tokenization for high-throughput pipelines, with multi-cloud deployment options and configurable data residency per tenant to meet your compliance requirements.
Vendo is the customization layer that lets your users build their own features and micro-apps directly on top of your product. Rather than waiting on an ever-growing feature backlog, your users can personalize the product to exactly how they work, create their own automations, and integrate hundreds of external tools, all without your team writing a line of code. Everything runs on your existing API, renders natively in your own theme and components, and executes inside secure sandboxes within your existing security guardrails, so your source code is never touched. Companies can plug Vendo into an agent they already have, or deploy a production-ready agent complete with the ability to take actions in the product, generate UI, and draw on a built-in knowledge base. Vendo is open source and installs with a single command, and we work closely with teams to get it running for their product.

Verdant is building the AI infrastructure for local government, and we’re starting with AI-native end-to-end permitting software that dramatically cuts local government permit review time. We help applicants file complete, compliant applications upfront, then help staff review them - our AI reads documents, plans, and diagrams, then flags issues and drafts the final report. Staff just sign off. Pandemic-era incumbent contracts are churning because staff are stuck with legacy systems that only intake and track permits – no automation involved. Our end-to-end solution picks up where those systems stop, automating the review itself to fix permitting where it's most broken.
Verdex is building the infrastructure to modernize agricultural risk. We fuse high-resolution satellite imagery and weather models to monitor fields 24/7, allowing insurers to settle claims without ever leaving their desks. We are currently helping to insure over 11% of all American farmland.

VetRec automates the process of taking clinical notes for veterinarians in a matter of seconds. Veterinarians should just review clinical notes, not spend time creating them. A visit with a pet is precious and 100% of the focus should be spent on the pet, not on notes. VetRec is the veterinarian's best friend.
Veterinarians spend 40% of their time on admin work, >20% on note taking alone. We're here to change that so they can focus on what really matters - providing the best care possible for animals.

At Village Labs, we help America's businesses become employee owned by helping them set up and manage an employee stock ownership plan (ESOP). ESOPs are a federal retirement plan that enable businesses to give their employees a stake in the company in exchange for significant tax benefits. With 2.9M Baby Boomer business owners set to retire in the coming years, there's a growing "Silver Tsunami" of businesses across the country in search of new ownership. For many of these owners, selling to their employees is a socially-minded yet financially pragmatic solution. By selling ownership of their business to an ESOP, owners get a fair price, tax benefits, and the satisfaction of knowing their employees and legacy will be taken care of — things not guaranteed with traditional buyers like private equity. In turn, employees retain their jobs and get shares in the business that can help them create life changing wealth by the time they retire — imagine an office secretary retiring as a millionaire. Thousands of businesses across America like Bob's Red Mill, Harpoon Brewery, and Recology already have an ESOP, benefiting over 14 million workers and creating 2.1 trillion in employee wealth. We're excited about the opportunity to massively grow these numbers by making it simple for every business to become employee owned.

No more spreadsheets and papers!
Our app allows doctors to speak any language, eliminating the need for human medical translators in hospitals and clinics. Despite spending billions on in-person and remote translators—mostly through outdated call centers—hospitals still fail to provide adequate care for non-English-speaking patients. We're building the most accurate and compliant medical language translation system across voice and video modalities.
Void is an open source code editor with features similar to Cursor and GitHub Copilot. Unlike other tools, Void lets developers keep their data completely private by connecting directly to any LLM.
Voker is the analytics platform for monitoring and improving your AI agents. Companies like Lull.com and Dutch.com use our SDK to build better AI. Alex and Tyler met at a high-growth E-Commerce startup where Tyler was running Technology & Data. Together, they built AI products that bootstrapped the company profitably to $100MM in Revenue. Alex experienced firsthand the broken developer experience in AI while building enterprise infrastructure at Yardi. Even with a dedicated ML team, it took too much time to build simple AI features. It was clear that if large companies were struggling with this, SMBs would definitely be left behind. We went directly to our network of SMB operators and found our hunch was correct. Within a week we had two paying customers even before launching our first prototype.
Volley develops AI-powered, voice-controlled games and experiences for smart TVs, Amazon Alexa, Google Assistant, and mobile devices, offering a platform of voice-based games such as Jeopardy!, Wheel of Fortune, Song Quiz, and Question of the Day.
Voquill is the modern AI-native operating system for medical labs. This software manages the entire workflow of the lab (accessioning, workflow, reporting, coding, compliance, and revenue) and contains modern agentic AI tools to help each step. For example, pathologists can write reports 20% faster through our voice AI coworker. Incumbent lab operating systems are old, don't scale with how modern labs work, and can’t integrate existing AI solutions. As a result, labs are either building their own or paying millions for band-aid solutions and consultants. We're building an agentic platform to manage every aspect of the lab and displace the billions spent on legacy management systems.
Engineering is bottlenecked by slow, costly simulations. We're fixing that by building foundation models that learn physics end-to-end and deliver the same results in seconds, at a fraction of the cost.

VoxOps automates up to 80% of their inbound and outbound calls, whilst automating downstream workflows.
The best grid connection is no grid connection. Voxel data centers capture, store, and consume solar energy onsite without the grid, completely bypassing utility connection delays. By leveraging the vast supply of second-life EV batteries with our novel DC microgrid architecture, we drastically reduce engineering overhead and time-to-power.
We're 2 repeat YC founders. We founded Plato (W16, sold to Coda) and Wolfia (S22). Quang lead Product/GTM for Coda Solutions and Fabien is ex-SWE at Meta and lead Engineering at Wealthfront before. We’re building Vybe: "Lovable for internal apps". We come with pre-built building blocks: Integrations (Gmail, Gcal, Github, Jira, etc.), SSO and AI tools (Websearch, Summarization etc.) so anyone in a company can build and launch internal AI-powered apps. Vibe coding is dramatically lowering the barrier for non-technical users to create full web apps. Lovable, Replit, Bolt, Google, Canva, Figma all launched their vibe-coding platforms. People love them. They're great for prototyping, but it's difficult to roll out inside a company for internal use cases for those reasons: 1. Data: If you want to connect your existing data (e.g. Salesforce, Gmail, Jira), you'd need to rebuild the API auth, pagination, etc. 2. SSO: If you build 20 apps, you'll have 20 different logins 3. Security: AI-built apps have massive risk of exposing data, especially if built by non developers So companies are stuck in the old world: clunky spreadsheets, rigid SaaS solutions or complex no-code tools. Time to build!
WANTD is a D2C consumer marketplace for fashion and footwear brands to launch and sell product. We do the things Shopify is unable to do; we provide multiple channels to sell (e.g. live commerce, marketplace, auctions), influencer networks, and order fulfillment in a mobile-first experience. We solve the cold-start problem for brands and enable them to remain focused on product creation.
