Despite distribution being a multi-trillion dollar industry, the legacy ERP systems that exist to help businesses manage their purchasing, inventory, sales, order processing, and accounting are decades behind. For the most part, ERP systems are painfully slow, difficult to use, and soul-crushingly manual. Using Recurrency can boost a distributor’s revenue and profit margins, while reducing waste and saving time. Most importantly, Recurrency is fully integrated with the customer’s legacy system, so deploying Recurrency in production can be done in as little as one day.

    Our mission is to make the web more collaborative. We're not just making collaboration faster—we're crafting it to be the best. Today we’re all using online platforms more than ever before - building, researching, learning, connecting etc. And we're not doing it alone. We're doing it together with other people and machines, turning the internet into the world's biggest team. Yet, the web was built for solo voyages. We saw a shift when platforms like Figma and Google Docs brought a multiplayer approach, breaking down walls and inspiring seamless teamwork. At Velt, we're taking it further. We're on a mission to infuse the magic of collaboration into the fabric of the web—one app at a time. We aim to erase the lines between online and offline co-working, crafting an environment where distance is irrelevant, and 'flow' is the norm. Right now, more than half of work hours are spent on coordination and communication—less on creating. With Velt, we're setting out to reverse these figures, reducing time spent on logistical issues by over 90%. Imagine what we can create when we spend less time talking about work and more time doing it! We're building a better web—a web for us, for our team, for everyone. Join us, and let's accelerate the future of web together 🚀 Our Products: - Velt Collaboration SDK (https://velt.dev/): JS SDK to add powerful collaboration experiences to your own product for your end-users. This helps you ship such experiences ridiculously fast, increase user growth and engagement. - Superflow (https://usesuperflow.com/): JS plugin to enable product, marketing and design teams to comment and collaborate directly on their websites. This helps them iterate and ship their products 10x faster. We’re a team of ex-Googlers. We've launched products like Augmented Reality in Google Search & Maps. Come build a better web with us 🚀

    Our goal is to empower local government employees with the tools, technology, and support they need so they can deliver exceptional service to their taxpayers and feel proud of the work they do for their communities. We contribute by building software to streamline local government tax assessors’ workflows using AI. Specifically, we streamline the change of ownership process for real estate and create more seamless ways for tax offices to communicate digitally with their taxpayers. For instance, when properties get bought and sold, local governments have to process reams of paper in order to update their systems and perform the analyses necessary to update the tax roll. Our software makes this process 10x faster and much more enjoyable for employees in the tax office to complete, and creates trust and goodwill in the minds of taxpayers.

    Attain is a one-stop shop for convenience store owners to buy inventory across all their suppliers with higher reliability, price transparency, and product discovery. On average, store owners buy products from over 10-15 different suppliers each week. This painful process involves shopping in massive warehouses or spending hours working with wholesaler’s sales representatives (who sometimes don’t even show up). As a result, stores waste countless hours ordering products through extremely inefficient and tedious processes. These store owners are also severely impacted by inventory shortages and revenue loss which many times results in them downsizing their business or shutting them down completely. Attain solves this problem by providing a single app to purchase products across all of their suppliers, resulting in a one-stop shop for inventory. By aggregating inventory across a multitude of suppliers and wholesalers, Attain helps stores save significant time and money while allowing them to focus on what they do best - growing their businesses.

This is where imgix has your back. imgix is a platform for managing, processing, rendering, optimizing, and delivering your existing visual assets so that you can meet the demands of your business and your team can stay focused on what they do best. The business demands on web visual media can blindside even the most hyper-aware content teams and developers. Just to be competitive on the Internet, you need your images to be sized perfectly to every device, served in one of any of a half dozen web formats, optimized to the absolute best perceptual quality while maintaining pinpoint performance, and distributed to wherever your users are, anywhere in the world. And that is just the baseline. Next-level imaging concerns like copyright, licensing, accessibility, moderation, illegal or explicit content, "fake news", and more, can threaten your business at any moment if not handled properly. Get any of these things wrong and you are shedding revenue, ceding ground to competitors, and potentially exposing your business to extreme liability.

    Today the building design process is cumbersome and expensive. Architects submit their design to structural engineers for validation. Engineers need to design all structural elements such as walls, columns, and beams to ensure the structure will not collapse and complies with regulations. The structural engineer needs four to six weeks to generate the initial solution. The engineer will submit his proposal to the architect and then engage in an extensive back and forth discussion until they agree on a satisfying solution. TANGObuilder generates the building structural design in real-time, cutting six weeks of the overall process, and reducing material usage by 30%.

    Osmind is the premier platform for clinicians and researchers advancing new life-saving mental health treatments. Today, mental health disorders are one of the leading causes of death worldwide, especially among young adults, and are tied to shortening lifespans. While there have been developments in new psychiatric medications since the first FDA approval in 1954, today there is a growing movement among clinicians, patients, and researchers who are recognizing the need to accelerate new science. The Osmind treatment platform is the first and only solution that solves specific challenges faced by neuropsychiatric clinics, spanning general psychiatry and interventional psychiatry (transcranial magnetic stimulation, ketamine, SPRAVATO®, psychedelic medicine, electroconvulsive therapy). The core electronic health record (EHR) technology is precisely developed for interventional treatment workflows and designed to support a strong therapeutic alliance, including journaling tools and assistance with health plan reimbursement, which is a significant access hurdle for millions of patients. Research from our platform is already helping to set new standards for mental health interventions. For example, in the largest published real-world analysis of ketamine infusion therapy for depression, we teamed up with Stanford University School of Medicine to share findings in the Journal of Affective Disorders (March 2022). We have multiple ongoing research studies leveraging our proprietary real-world data, including an even larger ketamine analysis leveraging machine learning to predict treatment outcomes. Osmind is a San Francisco–based public benefit corporation led by scientists, technologists, and psychiatrists. We are backed by top investors including DFJ Growth, General Catalyst, Future Ventures, Tiger Global, and Y Combinator.
