  • Lawdingo (w2013)Active • New York, NY, USA
    Lawdingo gets people in touch with a lawyer very quickly. Lawdingo gives people seeking legal services direct access to independent lawyers who can help them. Such attorneys usually have more flexible hours, lower rates, and greater interest in customer service than to their larger firm counterparts. The problem is that there is so many such lawyers; how is someone supposed to figure out who is right for them, and who has some time to take on their case? Fair question. Coincidentally, we started Lawdingo to answer just that. If you're looking for a lawyer, we encourage you to try finding an easier way to get one to work for you. If you are a lawyer working in solo or small practice, we encourage you to find a more effective way to grow your law practice. We also encourage you not to take our word for it. Read what Solo Practice University, the ABA Journal, FindLaw, AboveTheLaw, TechCrunch, Lifehacker, and others say about us. This isn't some fly-by-the-night company. This is the future of the legal industry. We hope you'll get in touch. Lawdingo was started by Nikhil Nirmel (nikhil@lawdingo.com), an entrepreneur with a background at Yelp and Wharton Undergrad, and Dan Langevin , a ridiculously talented technologist who was formerly CTO of Lifebooker. Lawdingo has backing from Y Combinator and other investors.

    At Resolve we’re building the future of simulations using immersive technology like VR and AR. Today, Resolve helps bridge the communication gap between people who operate buildings and those who design and build them. We've built the most robust application for reviewing industrial facilities on wireless VR devices like the Oculus Quest - our customers love it because it just works even with complex 3D building models. From data centers to cutting-edge biopharma facilities, Resolve provides a collaborative virtual environment for operations & maintenance teams to review and interact with 3D building models at full scale - decreasing late stage changes during the construction process and delivering a safer, more easily operable building. Our customers' facilities contain a multitude of complex systems which require careful coordination and review to ensure the building is completed on time and within budget. To prevent rework and increased building maintenance costs, Resolve fixes the broken system of screen-sharing 3D models and 2D floorplans with the operations teams that inherit the building and, instead, gives them easy access to their 3D building models before concrete is poured.

    Vanta was founded in 2018, in the wake of several high-profile data breaches that shook our collective faith in internet businesses. Online security was only becoming more important, but we knew firsthand how hard it could be for fast-growing companies to invest the time and manpower it takes to build a solid security foundation. From our early days of automating security monitoring for compliance standards like SOC 2, HIPAA, and ISO 27001, to pioneering a brand-new market as the leading Trust Management Platform, our vision to restore trust in internet businesses by enabling companies to improve and prove their security remains unchanged. Now more than ever, making security continuous—not just a point-in-time check— is essential. Vanta is the leading Trust Management Platform that helps simplify and centralize security for organizations of all sizes. Over 4,000 companies including Autodesk, Chili Piper, Flo Health and Quora, rely on Vanta to build, maintain and demonstrate their trust—all in a way that's real-time and transparent. Recently named the #1 Leader in G2's Winter 2023 Grid® Reports for Security Compliance, Vanta debuted a number of new product innovations over the last year, including Access Reviews which automates the once-manual, time-consuming access reviews process and an enhanced Risk Management solution allowing companies to holistically understand, prioritize, and reduce risks within their company to build a stronger security approach and demonstrate compliance. Vanta was built on the idea that software can be used to do amazing things for the world—if we trust it to do so. And we can’t do it alone. Come join us!

    Ophelia helps people quit opioids without going to rehab. We offer online doctor’s visits, withdrawal medication prescriptions, and support for long-term recovery, using a protocol 6x more effective than most rehabs (2/3rds of which don't have doctors). More than 3 million Americans are addicted to opioids, but 80% are not getting help, due to jobs, families, and privacy concerns. Meanwhile, there's a proven treatment that increases survival rates by 600%, and it's low cost, discreet, and convenient. It's called MAT, and it looks like treatment for anxiety or depression: medication plus therapy. However, doctors need a special waiver to prescribe the medication, which fewer than 5% of them have, so it's difficult to get, and most people are buying it on the street. Sadly, drug dealers aren't doctors: every 11 minutes another American dies of an opioid overdose, now the #1 cause of death for Americans under 50. Ophelia is replacing rehab with telemedicine, using proven science and a consumer-first approach. The opioid treatment market in the U.S. is $15B, and 85% of opioid addicts have insurance that pays for it. We're treating roughly 400 patients with thousands more waiting. Zack started Ophelia after losing his girlfriend to an opioid overdose, who found it easier to get medication from a drug dealer than a doctor. We are raising money to help patients in waiting, grow our footprint, save lives, and earn venture-level returns for investors.
