Scrollmark is building SocialGPT, the first AI system specifically designed to decode social media algorithms and give creators, brands, and agencies the insights they need to succeed across platforms. Social media algorithms change constantly, leaving creators and brands scrambling to understand why their engagement suddenly drops. Most tools focus on scheduling and analytics; we focus on understanding why content succeeds or fails before you even post. Our AI engine continuously analyzes thousands of viral posts across social networks to identify: - Breakout patterns in the critical first 30-60 minutes after posting - Niche-specific trends that matter to your exact audience - Content attributes that drive engagement (hooks, captions, timing, formats) - Algorithm signals that predict viral potential Check it out at gpt.social Want to be a part of the Scrollmark Crew?

At Sprinter Health, we’re tackling one of healthcare’s biggest challenges: reaching patients who have fallen through the cracks of our healthcare system. With a boots-on-the-ground clinician network and the tech platform to solve this problem at scale, we bring critical preventive care to folks who are otherwise not getting it, whether due to disability, socioeconomics, transportation insecurity, or simply not getting around to it. We believe that access to healthcare shouldn’t be so hard, and by making it easier for folks to get the diagnostics and preventive care they need, we can halt the growing tide of disease and healthcare costs in America. Since launching in 2021, we're now live across 15+ states, covering over 60% of the US population and partnering with 6 of the 10 largest U.S. health plans. We've served >60k patients in-home from ages 3 to 103. And with 5x revenue growth in 2023 and 6x growth in 2024, things are only accelerating.

Pallet is building AI Agents to transform logistics — a $12 trillion global industry. We’ve raised $50M from top investors including General Catalyst, Bessemer Venture Partners, and Bain Capital Ventures. In under two years, we’ve achieved 700% revenue growth and are just getting started. Our mission is to increase the efficiency of the global supply chain by automating the manual workflows that slow logistics teams down — from scheduling and appointment setting to data entry and load management. Our flagship platform provides end-to-end visibility, control, and optimization, while our newest product, CoPallet, introduces AI Agents that can understand and execute requests in real time, and integrate directly with customer systems. As logistics providers look to generative AI to drive efficiency, many are turning to Pallet to lead the way. With deep industry expertise and cutting-edge AI capabilities, we’re positioned to build the next $10B company in logistics. Join us and work alongside leaders from Google, DoorDash, YC, and more to shape the future of logistics tech.

RDI is an overnight success — years in the making. We’re scaling fast (grew 4× last year), fueled by enterprise engagements with the top IVD manufacturers in the world. For a small team, we punch way above our weight. RDI has become the go-to CRO for large public diagnostics companies who rely on our creativity, tech-forward systems, and zero-excuses accountability to get trials done quickly and done right. We’re a fully integrated IVD CRO — a high-complexity CLIA lab, a technology-enabled CRO, and a national physician + lab network under one roof. This lets us run clinical trials with a level of speed and operational precision the industry isn’t used to. RDI was founded in 2008 and professionalized in 2017 through a search fund acquisition (not venture hype). We’re backed by long-term operators and growth investors — not dependent on VC burn or fundraising cycles. From 2022–2024, we expanded aggressively by doing the hard things right: building real infrastructure, earning trust from enterprise customers, and executing consistently. Our physician network was sourced from real insurance claims data and strengthened by CAP accreditation. No one has successfully started and scaled a modern CRO focused on diagnostics and medical devices in over 15 years. The industry is dominated by large, slow incumbents optimized for pharma — not speed, accountability, or precision. We’re the underdog — and we’re winning. Our goal is simple: prove our customers right, and prove the industry wrong. Get a feel for how we work: youtube.com/watch?v=3tccEbsWIl8
