We've built several businesses over the years, and each time, we faced the same challenges. We knew we needed to send sales emails, post regularly on social media, keep an eye on Google Ads, or simply manage the endless flood of emails—but somehow, these tasks always slipped through the cracks. The intention was there, but reality always got in the way. That's why we created Marblism: AI Employees who seamlessly handle the tasks you keep putting off. No complex setups or prompts needed—just tell them about your business once and let them work quietly in the background. Suddenly, those tasks you knew you should be doing actually get done, giving you more time and mental clarity to focus on what truly matters.

Maritime Fusion is building fusion reactors for ships and off grid energy markets. En route on this endeavor we’re commercializing High Temperature Superconducting (HTS) cable technology for power distribution while advancing the physics basis of our HTS tokamak to decarbonize global shipping. Breakeven fusion is coming soon, but the first-of-a-kind (FOAK) reactors will be costly, high maintenance, and have low capacity factors, leading to 5–10x higher electricity cost on the grid. Maritime Fusion is pursuing the most widely accepted approach to fusion, the tokamak, but specifically designed for the marine environment where the challenges that arise between breakeven and a commercially viable energy source are alleviated. The market we're targeting requires 15x less power, lower up-time, and costs the same as alternative fuels but without any emissions. Since fusion does not use highly radioactive fuels or materials – unlike fission – we sidestep the vast majority of regulatory challenges and safety risks associated with nuclear energy. Our team brings over a decade of industry and research experience in plasma physics, nuclear engineering, and electrical engineering with backgrounds at SpaceX, Tesla, Columbia University, and University of Pennsylvania.

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.

Metriport provides real-time access to comprehensive medical data for 300M+ individuals across the US. Our open-source intelligence platform helps organizations access, analyze, and exchange patient data while integrating with all major healthcare IT systems. If you’ve been to doctors in the US, you may have encountered the problem: how does a healthcare provider get access to your up-to-date medical history to treat you properly? Reliance on archaic methods is still the norm: typically, you or your provider need to call the facilities where you’ve previously received treatment (assuming you remember them all), just to have them send your records via fax (yep, fax). This can take weeks, only then to have a provider sift through hundreds of pages of unstructured docs, just to figure out basic things like your active medication list, what conditions you may have, latest lab results, etc. This not only delays care—it can cause improper treatment, since the medical history is critical for informing treatment decisions. Metriport integrates fragmented medical data from thousands of sources—including both national and state/regional Health Information Exchanges (HIEs), ADTs, EHRs, pharmacies, and labs—through a single API connector. The platform then standardizes, deduplicates, and enriches this data to create a comprehensive longitudinal patient record, with AI-powered clinical summaries. Along with a rich understanding of patient health history, healthcare providers also get realtime updates about their patients' health through Metriport. This includes getting notified when a patient is discharged from the hospital, picks up their prescription from the pharmacy, or has a new lab result available. Through this data, care teams get insights across their patient population, helping with 30-day readmissions prediction, care gap closure, risk adjustment, and more. On top of all of this, Metriport enables healthcare organizations to share net-new clinical information back to all major healthcare IT systems, and to become interoperable with popular EHR systems such as Epic, Cerner, athena, eClinicalWorks, and many more—forming an internet for healthcare data. Metriport improves both patient and provider lives at the point-of-care, supporting use cases such as medication adherence, transitions of care management, chart prep, and much more. If you want to do work that matters, get in touch with us today.
