Amazing Team. Visionary.

Pros

Illumio allows the IC to cut a path and build out their role. There's a great deal of autonomy with a huge focus on individual accountabilty. In other words, it's all about delivering. It's not your typical start-up trying to find it's way...there are very experienced players from diverse backgrounds as well as recent grads which lends to an amazing synergy of talent and know-how. It's an exciting place with an amazing product and a huge opportunity. Management appears to be in synch on an operational and strategic level. They're not afraid to ask questions and they know where to get answers.

Cons

A lot of rigor you'd normally see in a company much more mature which could become a blocker or could serve the team very well. Really high hiring bar, hopefully not overlooking unobvious talent.

Pros

The people I worked with at Illumio were truly fantastic — smart, supportive, and highly collaborative. The team culture at the peer level was one of the best parts of my experience.

Cons

Unfortunately, the management structure was very top-down. Leadership often felt out of touch with the realities of day-to-day work, and most major decisions were driven by the need to copy other products that were already on the market. This created a bottleneck for progress and made it difficult for teams to feel empowered or trusted to innovate. Despite the talent and dedication of the design and engineering groups, the lack of autonomy and over-centralized direction often stalled momentum and limited creativity. If Illumio can find a way to empower its teams and shift toward a more trust-driven, bottom-up culture, it could be an incredible place to work.

Hi there and thanks for sharing your initial feedback about your experience here so far. I agree with you that our approach to total rewards is market-driven and is both fair and competitive so that we can attract and retain the very best people. And I appreciate your feedback on the opportunity you see for us to continue to focus on leadership development. To that end, at our Onwards kickoff a few months ago, we hosted a Leadership Day to help align all of our people leaders, which is a commitment come we're focusing on throughout this year overall. Each of our people leaders will have dedicated enablement sessions on a regular cadence, which I'm confident will continue to pay dividends for both them and for the teams they serve. Please keep the feedback coming, and don't hesitate to reach out with additional ideas where we can continue to sharpen our focus! Thanks, David Chief People Officer
