    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.

    Dex is a personal CRM that reminds you to keep in touch with the people you would otherwise forget. Dex helps turn your acquaintances into your allies. Going beyond the superficiality of social networks requires commitment. If you remember to keep in touch thoughtfully, you can turn the interesting person you met at a networking event into a friend that has your back. I built Dex after failing to keep up with the tools I tried (Airtable, Notion, etc) for relationship management. Installing an actual CRM like Hubspot felt like a wrong fit for my informal relationships -- these people were 'my team,' not customers. Dex is a lightweight personal CRM that’s easy to stick with. Key to Dex is a Chrome extension that enables you to manage relationships while you’re in Facebook, Messenger, Twitter, and the social apps you already use. Dex can also send you actionable reminders (daily, or based on your calendar events) to log your interactions for next time. By using Dex, you can: - Build stronger relationships, by sending you a nudge to follow-up. - Be more thoughtful, by helping you remember where you left off. - Become a superconnector, by making connections you wouldn’t otherwise remember.

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.

    The trucking and logistics industry provides the backbone of the economy, but the payments infrastructure on which it runs is broken; the existing suite of payment tools is outdated, difficult to use, prone to fraud, and saddled with hidden fee structures. AtoB is building Stripe for Transportation — modernizing the payments infrastructure for trucking and logistics, where capital movement occurs quickly and transparently. Our flagship product is the AtoB Fuel Card, a zero-fee fuel card accepted anywhere built for fleets of all shapes and sizes.

Varos is pioneering a new category of data analytics that’s challenging traditional taboos around cross-company collaboration. Varos’ platform helps its users understand their own performance vs. direct competitors by unlocking data that is currently stored in different silos. In fact, a growing base of thousands of users are already automatically feeding marketing data to Varos’ platform, and in return seeing how they stack up against others in their space and stage. However, Varos is not planning to stop there, and is already planning its expansion across additional operative departments, such as finance, product, and sales. Companies today are flying blind because they only rely on their own historical data and don’t know how their metrics compare to their competitors. Varos increases revenue for our users by accurately showing them how their metrics compare against similar companies so they can decide which KPIs to double down on and which to spend time fixing.

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 🚀

    Active • 2 employees • Berkeley, CA, USA
    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.
