    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.

    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.

This allows hospitals to stop wasting precious nursing time defrosting milk for hours and milk wastage from discarding rules. Simply weigh the powder, add water, shake and serve. No more freezing, no more defrosting, only patient care. NICUs are time sensitive wards in the hospital, time is everything and yet nurses today continue to prepare frozen milk for infants in what's known as the milk shift. A shift where the nurse spends the day defrosting milk for the next shift of nurses. Our tech is now fully peer reviewed and published, yielding safe and reliable results in over 20 hospitals in the New York Tri-State. The company is headed by Vansh Langer MD, a physician (Windsor University, University of Chicago) and Blanca Aguilar Uscanga PhD, a Bioengineering/Food Science PhD (University of Guadalajara /Centro Universitario de Ciencias Exactas e Ingenierías (CUCEI)) team that has over 50 published works in the field between them and are experts in the science of infant nutrition.

    Wyndly (https://www.wyndly.com) fixes allergies by training patients' bodies to ignore their allergy triggers. Frustrated allergy suffers come to us when they no longer want to deal with pills and sprays. We diagnose the patient’s unique allergy profile and create a personalized treatment plan to give the patient lifelong allergy relief. Specifically, Wyndly is increasing access to sublingual immunotherapy (SLIT) for allergy care. For our patients, we're combining the convenience of telehealth and direct-to-consumer care with an exceptional patient experience that never loses the context of care. Wyndly represents an opportunity to change allergy care forever. With 60 million Americans suffering from allergies today, and with this number doubling over the coming years, there's simply an incredible need for the convenient care Wyndly provides. You can read more about us in [Techcrunch](https://techcrunch.com/2021/02/12/wyndly-aims-to-bring-allergy-drops-to-the-masses/). The Wyndly Model At Wyndly, we believe that better connections lead to better care, and we’re committed to making both happen at every step of the patient journey. Our allergy practice allows our patients to work with expert providers to develop personalized treatment plans for long-term allergy relief using clinically proven therapies. From a patient’s initial consultation to their final treatment delivery, we want the Wyndly experience to be a breath of fresh air for allergy sufferers – truly effective allergy relief, simply and efficiently delivered. Once we've conquered allergies, we're transforming the care model for every chronic condition. While transactional care for purchasing pills has flourished in telehealth, no one has gone after chronic care. Patients with chronic conditions are shuffled between providers, insurance, and more -- and they never feel heard. These patients deserve better, and we're going to give it to them. Wyndly is starting with allergies, but we'll expand into asthma, sleep apnea, and other conditions in the near future. Our values **Compassion**: We approach all our patients and partners with an open mind and a genuine desire to be of service. **Focus**: We do a few things very well, and are always clear about our boundaries and direction of travel. **Courage**: We embrace ambiguity and discomfort because we know that’s how we grow. **Progress**: We make something better every single day. *It boils down to empathy and forward momentum in everything we do.* The team Wyndly is proudly backed by Y Combinator and a leading group of angel investors and VCs. The founders are Dr. Manan Shah (Chief Medical Officer), an ear-nose-and-throat surgeon who’s a leading practitioner of telehealth in his specialty, and his cousin Aakash Shah (CEO), who led growth engineering at SparkGift (acquired by Stockpile in 2016) and Parse.ly (acquired by Automattic in 2021).
