    Recurrency is reversing enterprise resource planning (ERP) stagnation by building the industry-standard ERP automation platform: blazingly fast and complete with powerful automation tools like intelligent sales recommendations, dynamic pricing, and demand forecasting. 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.

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 🚀

    Peer5's P2P CDN improves content delivery for live and on demand video streams. As video streaming continues to become more mainstream and the streams themselves become HD and 4K, traditional CDNs struggle to deliver high quality viewing experiences. Many publishers try to keep up with peak demand by paying for more servers, many of which are almost never used and struggle with video playback. Not only is this expensive, but it's also inefficient, which is why at Peer5, we've created a P2P CDN to boost your video streaming capabilities. Our CDN works with your servers to ensure that as your viewership increases, your network gets stronger by offloading bandwidth to our peer network. On average, this has been shown to increase server capacity by 20x, offload 70% of bandwidth, increase viewing time by 30% and decrease instances of rebuffering by 40%. Our video streaming CDN uses emerging technologies, including HTML5 and WebRTC. They require no installation by end users and offer easy integration for content providers. We support many different streaming protocols, players and media servers.
