Why beehiiv?

• Bias towards action: Our first impulse is to act. We don’t get bogged down in unnecessary processes or bullsh**t. Perfection is the enemy of progress.
• Ownership mentality: This company is ours. We go the extra mile because that’s what owners do. Every day, people step up to take on tasks outside of their responsibilities and do whatever it takes for us to succeed.
• Building is in our DNA: We are obsessed with improving every aspect of our platform (and ourselves). Whether it’s our product, support, or partnerships, we never stop working to improve it.
• We answer to our users: Nothing matters more than serving our users. If our users fail, we fail.
• Ego comes second, but winning comes first: We put our egos aside to work collaboratively and build something special. It doesn't matter who's idea or who's vision, we're here to create the best outcome. We're here to win.

We'll take care of you:

• Competitive salary
• Stock Options
• Health, Dental, and Vision Insurance
• 401(k) employer match
• Unlimited PTO (mandatory 10 days per year minimum)
• Annual in-person team retreat
• Unlimited book budget
• Monthly Wellness Days (every third Friday of the month)
