Backpack is a peer-to-peer platform that connects travelers and shoppers to give people access to products across markets in all continents. Each backpacker, regardless of their role as a carrier or a shopper, follows a simple four-step process to either earn or save money from their backpacking experience. Travelers share their travel information and specify what kind of items they want to carry. Then they wait to get a "backpack request" and ask their price. Finally, they confirm the deal, buy the items, deliver them and earn money. Shoppers on the other hand, search items from their favorite websites and fill out the item description. Then they give their location and find a traveler coming to their city. Finally they "request backpack" and confirm the deal. Within days they can get the product and save money. backpack is founded with a vision to provide every citizen of the world with a choice; the choice of buying organic, authentic, and cost effective products with minimum friction. Whether the product is state-of-the-art consumer electronics, exotic pashmina from the south-east, or even medication that are rare in some parts of the world and not so rare in others - we promise ourselves to get those products to your doorsteps. We would like to reject the counterfeits, we would like to reject the almost-originals, most importantly, we would like to not pay the heavy expense incurred, most of which we deem to be superfluous. Help us make a better, more original globalized world.

These are gasoline, diesel, and jet fuels that work in existing cars, trucks and planes without requiring modification of their engines, and don't contribute to global warming because they don't add any new CO2 to the atmosphere. Each gallon of our electrofuels means a gallon of fossil oil left in the ground forever. Importantly, these fuels for the first time can compete with fossil fuels on price - our zero net carbon jet fuel has a price of one cent per gallon less than fossil jet fuel.

    Our customers use Freshpaint to make their websites and entire marketing stack HIPAA compliant. It's impossible to use modern analytics and marketing tools without sharing sensitive HIPAA-regulated data. Our platform does the hard thing of moving data from A to B. And then we do the really hard thing of controlling the flow of sensitive HIPAA-regulated data to various 3rd-party marketing tools. We're building the data infrastructure that safeguards patient privacy while also enabling marketing teams promote access to healthcare.

    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.

    ModernLoop helps every company automate and streamline recruiting operations to deliver the best candidate experience. In 2022, the Department of Labor estimates there is a global talent shortage of 40 million workers, and that number is expected to grow to over 85 million by 2030. In order for companies to win the war for talent, they need to provide a best-in-class candidate experience to recruit top talent, and our product aims at doing just that! Our founders Lydia Han (CEO) and Chris Triolo (CTO) both founded ModernLoop in December of 2020 after they saw the challenges recruiting teams had when it came to coordinating hundreds of interviews across various teams, all while making sure both hiring managers and candidates had the best experience possible. After spending 15+ combined years at companies like Facebook, Slack, Brex and Salesforce, they understood what it took to enable talent teams do their best work, and are building a product to scale alongside them as they grow. We created ModernLoop to serve companies of all sizes in every industry to help Talent teams interview candidates quicker, easier, and enhance productivity of teams as they continue their search for top talent!

    Many workflow builders and automation tools have support for adding logic to your processes, but get complicated quick– to the point where process owners are unable to edit them directly and require specialist services. Rulebricks separates decision-making logic from your workflows, giving your team a clear visual, spreadsheet-like interface to manage the changing rules that drive your business, and use those rules as API endpoints, visual forms, and in automation tools like Zapier.
