    Galactic Resource Utilization Space, Inc. (GRU Space)
    Y Combinator LogoW2026
    Active • 5 employees • Los Angeles
    GRU Space is building permanent lunar infrastructure to make humanity interplanetary within our lifetime, starting with the first hotel on the Moon. In just 6 weeks, we built the world's first Moon factory: patent-pending hardware that turns lunar regolith into bricks and inflates modular pressurized habitats designed to withstand lunar temperature and pressure extremes. Our first mission lands on the Moon in 2027 to demonstrate in-situ brick manufacturing and habitat deployment. A second mission lays the hotel's foundation inside a lunar cave, and a third opens the first lunar hotel, targeted for 2032. We don’t stop at Moon hotels. GRU’s long-term plan: 1. Build the first hotel on the Moon. GRU solves off‑world surface habitation. 2. Become the Moon Base Company of America: build roads, mass drivers, warehouses, and physical infrastructure. 3. Repeat on Mars and build the first cities there. 4. Own property on the Moon and Mars as these economies grow. 5. Reinvest profits into resource utilization systems on the Moon, Mars, asteroids, and beyond—reaching our final form: Galactic Resource Utilization. GRU Space is backed by investors in SpaceX and Anduril, is part of Nvidia's Inception program, and our launch generated 1B+ views across 60+ countries, earning invitations to the White House, Senate, and Pentagon.

  • Merlin AI
    Merlin AI
    Y Combinator LogoS2024
    Active • 19 employees • Los Angeles
    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.

    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.

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.

    Active • 8 employees • Los Angeles
    With five issued patents covering our core business lines, and more than a dozen additional patents pending this year and more than $5M in revenue, TransAstra is developing the technologies that will drive the rapidly expanding space economy. Our breakthrough Omnivore propulsion system can propel spacecraft, including our Worker Bee commercial OTV with water or virtually any other fluid as a propellant using only concentrated sunlight as a power source. Omnivore is faster, cheaper, and more practical than electric propulsion while being substantially less expensive, safer, and more operationally flexible than legacy chemical propulsion systems. Our Sutter Telescope System can identify and locate resource-rich asteroids and orbital debris that existing technologies can’t find and works synergistically with our Worker Bee OTV for orbital logistics. For government customers, Sutter can identify dark fast-moving objects between Earth and the Moon which currently evade detection, a critical issue for national defense and a key need of the Space Force. We are already using Sutter in ground-based observatories and will begin commercial sales of Sutter SDA data next month having tracked dozens of faint moving objects in space already. Once launched into space, Sutter will be 300,000 times more cost effective than any other known telescope design and will revolutionize sense making in space.
