PLEASE do your due diligence before wasting any time interviewing with this company.
The picture they paint of themselves as a "re-startup" is dishonest. Google "Sundaysky data breach" and ask them why they changed their business model. Ask them how many of their big logos one their website are from the current business model they want you to sell, and how many are from the legacy model that they're phasing out because of the data breach.
Then take a look at leadership and ask why Marc Zionts hasn't led a company for more than 2 years since 2012. Ask about his leadership style and feedback when goals aren't met. See who takes accountability and who points fingers and where.
GTM is a mess. SDRs and AEs running completely separate motions, being led by leaders who have never prospected/sold or haven't in years. Goals are all based on hypothetical models using "data" that is based on a lot of assumptions and hope from leadership, and the reps take the fall when org can't meet the expectations set from incompetent leaders.
The product in theory has potential. In practice, personalized video is just a niche use case and even at scale it's not a need-to-have for businesses. As an end-user think if a business sent you a personalized video would actually move the needle for you?
