    BotCity (w2022)Active • 18 employees • San Francisco, CA, USA
    The rise of Robotic Process Automation offered a promise that any business user can build automations. We were skeptical about that and decided to talk to users of platforms such as UiPath, Automation Anywhere, and Blueprism, all of them low-code. Talking to users, we discovered that unique automations incorporating exclusive company processes and intelligence that have the potential to transform the business must be implemented by tech teams. It's not about mimicking employees performing isolated tasks. It's about designing a new workflow, integrated with the company's technological stack and systems. There are just 100.000 RPA skilled users compared to 22M developers globally that can become RPA coders on Day 1 with BotCity. We believe that all automation efforts in a single platform is more efficient. We started delivering the best RPA experience for tech teams, but we envision creating the perfect place to also manage crawlers, integrations, scrappers, data operations. Every company automation in a single place. As companies are becoming tech first and automation will be a basic KPI, we are building to be the all-in-one automation ops management.

  • Command AI
    Command AI (s2020)Acquired • 35 employees • San Francisco, CA, USA
    At Command AI, we believe in a world where the internet “just works” for every visitor, customer, and user. As the internet has become more powerful and crowded, it has become harder for everyone to use. And the solutions we’ve come up with to date — like irritating chatbots and pestering popups — end up being ignored or even annoying users more than they help. We sell tools to software builders and buyers to help them make their software better for users. We call this as our User Assistance Platform, and it comes in 2 pieces: - AI Agent — an AI chat agent that can answer users questions, perform actions for them, and even co-browse with them to teach your interface. - Nudge Platform — AI-assisted nudges, hints, and messages to guide users in personalized ways that don’t annoy them. We do this by optimally delivering nudges based on in-product behavior not just static rules as well as measuring measuring and the extent to which users “rage close” nudges to avoid pestering them. A replacement for legacy Digital Adoption Platforms User assistance translates into concrete outcomes like improved engagement, feature adoption, conversion, and retention, all while decreasing low-value support tickets. We’re used by teams like HubSpot, HashiCorp, Yotpo, Thryvv, and Freshworks.

  • Appjet (s2007)Acquired • 3 employees • San Francisco, CA, USA
    Y Combinator funded AppJet is an online programming tool for building simple web apps. Founded by former MIT students, AppJet intends to simplify the process of writing web applications. The applications are programmed on a web based text editor in the simple but powerful JavaScript programming language. JavaScript is used on both the server and client side. They've included several bundles of code libraries for databases and more importantly interfacing with the Facebook API. In order to efficiently host users' applications, AppJet has developed their own application virtualization system. The system allocates processor time to active applications and cuts off greedy ones after running an alloted number of compiled lines of code to prevent abuse. AppJet as a dev platform seems no longer to be active. There are some legacy downloads available, however.
