Our take
Feature flags are a powerful software development tool, allowing teams to modify system behavior without changing code, therefore minimizing risk. If a business has a new feature they want to test, they can then roll it out to a small set of users before letting it go live. These companies can, for example, get quick feedback on the new feature and fix any bugs, or roll back any changes.
LaunchDarkly allows companies to run tests like this by activating the new code for only a small set of users prior to launch. Typically running these tests requires lots of developer time - a daunting and expensive prospect for most rapidly growing businesses - and can risk disruption to the user experience if testing takes place on the live product.
The platform is used by more than 1,500 customers, including the likes of IBM, Intuit and Atlassian. Signalling a change in strategy, the company shook up its management in 2023 and is now aiming to scale its already strong growth under the leadership of Dan Rogers, a product and marketing specialist with an impressive track record at Rubrik, AWS and Microsoft. It is now well poised to develop into a leading business in the feature management space.
