Being part of the Inc. 5000 is an honor for any company. It signifies rapid and consistent scalability, with this year's honorees ranging from nearly doubling their growth to the top spot claiming a staggering 157,144% 3-year growth rate.

Inc. publishes these private companies' names, growth rates, locations, and industries "but dealmakers need a lot more information to determine whether an organization fits their investment criteria. Today's market is also extremely fragmented and impossible to accurately segment using traditional classification methods.

So, to help dealmakers learn more about and better sort through the highest-growth companies within this year's list, we decided to run it through our deal sourcing platform. The platform connects data from across tens of thousands of sources to generate highly accurate, fresh, and complete private company profiles.

By combining this information with our sophisticated classification algorithm, we're able to apply more flexible and precise industry designations that allow for companies to belong to multiple industries based on their complete range of markets and activities. Next we used Sourcescrub's custom scoring to rank all the businesses on the list based on a number of factors and data signals proven to indicate private company growth trajectory and investment readiness. Last but not least, we sorted the companies in each industry by 3-month growth rate.

Below, we list five of the industries featuring the highest concentration of private companies on Inc.'s 2023 5000 list, as well as provide descriptions for the top five fastest growing companies within each category. Let's dive in!
