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 🚀

    Most revenue teams have difficulty getting the right team members and internal stakeholders involved in a deal at the right time which creates waste of resources, delays deals, and causes deal slippage. With Prelay's team selling software, coordination and communication is all organized within one purpose-built platform integrated with your other key software instead of spread across multiple disjointed collaboration tools without any centralized tracking, oversight, or learnings. Not only are there fewer headaches for sales reps and their technical counterparts, but sales, presales, and revenue operations leaders have more insight into where and how resources are being used as well as how effective they are at surpassing their goals. Prelay enables your revenue team and its internal stakeholders to coordinate and communicate effectively so you can drive more revenue faster as a team. Prelay is also backed by top-tier investors including funds like Y Combinator, SV Angel, Liquid2 Ventures and executives from Box, Dropbox, Palantir, SAP, and Microsoft.
