Merlin is an AI-powered ERP for construction companies. We provide construction companies with a single, AI-powered platform to manage their entire business operations. Our platform unifies project management, materials management, finance, estimating, and CRM—traditionally scattered across multiple systems—into one cohesive solution. For the first time, construction firms can automate and oversee every aspect of their projects in a single, intuitive system. Today, construction companies pay for 8-17 different tools - that we eliminate the need for. We reduce - Manual work by 60% - Cut software costs by $10,000 monthly - Complete projects 3x faster. Why Now? We're witnessing a perfect storm of factors: decades of stagnation in traditional ERP systems, a multi-billion-dollar industry built on misaligned incentives, and the transformative potential of AI. This confluence creates a rare cyclical opportunity for market upheaval. The last major shift in this space occurred in the 1990s with the advent of digital systems, and now, 30 years later, we're on the cusp of another seismic change. Customers are crying out for innovation and as AI reshapes the landscape, early customer signals indicate an eagerness for smarter, more efficient systems. It's a unique window of opportunity that opens perhaps once in a multi-decade chance to redefine an entire industry's operational backbone. Team: KS, a BITS Pilani grad and successful startup co-founder, and Ayantika, an IIT alumni and tech expert, bring extensive coding and product development expertise together bringing about over a decade of technical expertise. Sneha ( that’s me), with over a decade of experience in supply chain management and lean manufacturing within the construction industry, has lived the pain of using ERPs in this industry.

Yondu is creating the robotic workforce of the future starting with logistics automation. We're deploying humanoid robots in the first flexible, drop-in picking automation solution designed for 3PLs.

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?

At Serif Health, we are taking the complexity out of the cost of healthcare. Our mission is to make healthcare pricing and contracting more transparent, easier to understand, fairer, and ultimately more affordable for all. New price transparency regulations have made a wealth of healthcare pricing and reimbursement data publicly available for the first time, but it is still extremely hard to ingest, organize, and actually use this data to understand the cost of care. That’s where we come in. Serif Health is building healthcare price intelligence data products and APIs to power the future of more transparent healthcare. We are an early-stage, venture-backed startup with a small, collaborative team of healthcare experts, engineers, and designers. We are excited to add new team members motivated by our mission, passionate about making a difference in healthcare, and looking forward to learning and growing from the challenges we will face along the way!

Impossible mining is building underwater robotics vehicles which collect battery metals from the seabed without harming the environment. We have $500M+ in off-take LoI’s and have signed a partnership with a global offshore logistics company which holds a seabed mining exploration permit. We have also built the 1st PoC underwater robotic arm. Polymetallic nodules are rocks which are rich in critical battery metals. Specially nickel, cobalt, manganese and copper. These metals are the the most expensive part of EVs.

Auto parts retailers get product data from hundreds of manufacturers that is inaccurate and inconsistent, often with big gaps in key values. They currently have a team of "catalog managers" who are required to process and enhance this data line by line, resulting in a week to months long lag between receiving product data and actually being able to start generating revenue from those products. Versable leverages AI to scan the web for tens of millions of auto parts listings, and uses a fine-tuned LLM with RAG to instantly process, enhance, and transform data. With just a part number, Versable is able to generate market-ready titles, product descriptions, and specs, in any format that's needed.

Plotdrive is the first continuous production system for narrative — infrastructure that transforms how long-form stories move from imagination to completion. Most books don’t fail for lack of talent; they fail when the workflow collapses somewhere between page 80 and page 300. Founded by brothers with backgrounds in high-stakes poker, VR, and narrative systems, we built what we couldn’t find: an engine that holds the entire shape of a story while authors work inside it. Writers see 5-10× gains in throughput without losing their voice. Manuscripts that sat untouched for years finally reach the finish line. Authors are using Plotdrive to break decade-long blocks. Publishers are using it to rethink how story pipelines should operate when continuity, context, and editorial craft can finally scale. The printing press made distribution industrial. We’re making completion industrial — creating the foundational layer for how narrative gets made at scale.
