    I have been working at Optimizely full-time (More than a year)


    I have been at Optimizely over a year. In that time we have moved from a company with one product to building a platform that customers love. Optimizely has gone through growing pains moving from selling into small accounts into a full blown enterprise company. As we grow, change is bound to happen and will continue as we hit more milestones. We are hiring more people that have worked in high growth and scaling companies and that makes it very exciting to be here.

    I like working at a company where we all know the impact of our contributions. I see the executive team working well together and being very thoughtful with decisions that impact the employees.


    At times we worry about consensus in making decisions. It can slow us down. We have a great office space, but we aren't as integrated as we could be on each floor.

    Advice to Management

    Keep the momentum going.
