High Expectations, High Growth, Meaningful Mission

Pros

DNSFilter is a place for people who want to be challenged, grow quickly, and make a real impact. The mission is meaningful, the people are smart, and there is a strong culture of candid feedback and continuous improvement. Leadership encourages debate, listens to good ideas regardless of title, and is willing to adapt when presented with better information. Those who embrace the challenge tend to thrive.

Cons

This environment is not for everyone. Expectations are high, accountability matters, and ideas are regularly challenged. People looking for a slower-paced environment or constant validation may find the culture uncomfortable. Like any growing company, there are growing pains and changes in priorities as the business scales.

The ship is officially sinking. Toxic from the top down.

Pros

The remote-first aspect was great while it lasted, but leadership is actively dismantling the few good things this company had going for it.

Cons

Toxic Culture and Lack of Accountability. The culture here starts at the very top, and it's incredibly toxic. The CEO has openly insulted the entire workforce during all-hands meetings, calling employees "sad, sloppy, and pathetic." Since then, real communication has stopped—now we just get pre-recorded, scripted videos of him in his penthouse talking about "transparency." Case in point: in one video, he promised everyone that remote jobs were safe, and shortly after, an entire remote team was laid off to be replaced locally. Extreme Nepotism and Vanity Spending. If you aren't a favorite of the executive inner circle, don't expect to get anywhere. Nepotism is rampant. Family members are on the payroll, and certain people skip the standard hiring process entirely, landing Director titles with close to zero experience and getting promoted within a month. Meanwhile, company funds are burning through the roof on the CEO's personal hobbies and sports sponsorships that no one else in the company cares about, while actual working teams are stretched thin. The high turnover of executive assistants tells you everything you need to know about what it's like to work closely with leadership. Severe HR Failures and Treatment of Women. The way women are treated here is a massive red flag. At a recent company offsite, a top executive displayed disgusting, toxic behavior toward multiple female employees while heavily intoxicated, and faced zero consequences. The most alarming issue is how HR and Legal handle workplace misconduct. HR protects the leadership team rather than the employees. The environment has become so toxic for female professionals that multiple successful, tenured women chose to resign simultaneously without fallback roles just to escape the culture. Do not expect HR to support you if you raise a legitimate concern.
