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.

GrowthBook is an open source platform to help companies make data-driven product decisions with feature flags and A/B tests. Existing SaaS solutions like LaunchDarkly require a company to send all of their data to them. This results in high costs, data compliance issues, and vendor lock-in. As a result, many companies end up building their own platforms in-house, which can take thousands of hours of work and lots of headaches. To solve this, GrowthBook uses a company's existing data infrastructure and business metrics. We believe feature flags and experimentation are the right way to build products at scale and that they will become a standard part of the development process. GrowthBook is well positioned to be a leader in this growing market.

Close customer support tickets faster with AI. We’re building AI infrastructure to power customer support at scale. With Markprompt, companies can automate customer support, scale without increasing headcount, and deliver exceptional user experiences. Scaling customer support with headcount is expensive, with human resources accounting for 90%+ of customer support expenses. On top of that, customer support agents often burn out leading to turnover and reduced quality. As companies grow, so does their expert knowledge, which is hard to access at scale and makes keeping employees up-to-date nearly impossible. Markprompt addresses the root of the information access problem by indexing all available knowledge within a company, setting the foundation for a robust system of record to feed the AI. Built from the ground up with an API-first approach, Markprompt provides SDKs (such as React hooks and components) and no-code tools to enable integrations at all touchpoints in the customer journey.

At DAGWorks Inc. our goal is to change how data + ML + LLM teams are staffed and operate. We’re building an open core SaaS platform to streamline development and operation of data, ML, & LLM pipelines in a collaborative, self-service manner, utilizing a company's existing MLOps and data infrastructure. We believe self-service for Data Practitioners is the future because it enables domain modeling experts the velocity to iterate on pipelines & models without hand-off, which is key for businesses using ML/AI to differentiate themselves. Unless you’re a big tech company or someone like Stitch Fix that can afford a platform team, staffing teams with high ratios of engineers, or finding unicorn data scientists that can build pipelines is your only option; it not only slows time to value, it makes operating ML/AI expensive. We’re here to change that. Think simple python that enables a low software engineering bar to describe what should happen, and then with some extra metadata, generates the workflow code, and that also consolidates several MLOps tools into a single platform, all in a self-service manner. It’s functional and usable by junior and senior folks alike.
