Blame It on Culture.

We tend to think of business and sales cultures for how they enable, elevate and extend our work. A strong culture gives our people clarity on the mission, helps them make appropriate decisions and level sets the expectations around behavior and tone. Good culture provides a platform on which a lot good things can be built.

But culture can - and our fast-growing digital marketing world, often does - fulfill a darker purpose. If left undeveloped, company culture can be the low ceiling that shackles your people, stymies your growth and assures that the potential of your people and technology will remain unfulfilled.

Over the past two decades I've had the chance to work with hundreds of digital media and technology companies, big and small, and have been exposed to hundreds more. Patterns repeat and familiar scenarios play out in a continuous loop. Well-meaning CEOs and compliant leadership teams fail to recognize the warning signs that their "culture" has become little more than a license to perpetuate bad behavior and poor decisions. Here are a few of the more toxic cultural models and how they could be holding your business or sales team down.

Flat and Leaky. Having started the company with an idea, three other guys and a dog, the CEO wants to stay accessible to everyone - despite the fact that the company may now have scores or hundreds of employees. The illusion of an "open culture" obscures the fact that he's undermining all of his managers and department heads and sowing confusion and generally gumming up the works.

"Watch How Cool and Busy We Are!" You just think you're a culture of multitaskers equipped with all the latest digital tools. You are actually a culture of clueless tools incapable of providing full attention and respect to people and ideas. Perpetually late for meetings, constantly doing email at the expense of those in the room. If you don't start calling out and ostracizing this boorish behavior it will kill your company.

"Bro!" A closet full of hoodies and Adidas shower shoes does not make you Mark Zuckerberg. But beyond the stunted sartorial choices, "Bro-Culture" can cause some serious problems. Ask the women in your organization how welcome and empowered they feel in the office every day? And when you invariably hire the inevitable second wave of experienced sales and tech pros, watch how the bros close ranks.

"We Got This!" The one quality most likely to cripple a company culture? Self-congratulation. It's great to have confidence in your technology, but craving the certainty that we have "the right answer" can easily bleed into "we're right about everything." To succeed, you need a company of seekers; an openness to well-meaning dissent. Hire the curious and weed out the absolutists.

Peter Drucker famously said that "Culture eats strategy for breakfast." Ask what your culture is swallowing that might better be used to nourish your team.
