An Insider's view of Liftoff

What's something quirky about your company?

Best part of Liftoff is the company-wide, mutual encouragement for all to lead w/authenticity, courage, & compassion. Whether it’s fun self-expression or the tough acknowledgment of BIPOC societal & workplace inequities, there’s a tangible motivation to embrace & share my uniqueness & inherent personal responsibility to support the same in others.

Alex

Sr. Sales Engineer

How do you collaborate with other teams in the company?

I think about collaboration as sharing & aligning goals, which creates business alignment. Setting clear goals & direction fosters collaboration toward a common effort, & understanding each other's priorities helps in achieving this win-win scenario. Ultimately, I believe transparency builds mutual trust, enabling us to achieve more as a company.

Manager, Regional Sales, Greater China Region

How has your career grown since starting at the company?

I started as an intern and accepted a full-time offer because I knew my team would be supportive of my professional goals. So far, in my first few months, I’ve led a companywide lunch & learn, and I became my team’s culture lead. Overall, I’ve exceeded my expectations in expanding my skill set and have become more confident in my professional self.

Maya

Business Intelligence Analyst

How do you make yourself accessible to the rest of the team?

I love interacting w/Liftoffers at a human level & keeping a pulse on our culture & team morale. I do this in proactive ways through quarterly regional CEO fireside chats, bi-monthly CEO breakfasts w/groups of 3-5 team members, ad hoc walk-and-talks, & monthly team all-hands. I also encourage team members to put time on my calendar as necessary.

Mark

CEO

How do your team's ideas influence the company's direction?

Everyday the decisions the ACP team makes on creative optimizations influence Liftoff’s business success. Our job is to tell a more compelling creative story for our customers based on A/B tests. Finding a new animation style or playable concept that gets users excited is not only a win for the customer but for us at Liftoff as well.
