Twitter CEO Exit: When Wall Street Clashes With TechTwitter CEO Exit: When Wall Street Clashes With Tech

6 Cool Tech Internships You Wish You Had

There are very few CEOs who show a 74% revenue increase year-over-year and then step down. Twitter CEO Dick Costolo did, claiming he was tired of the pressure from Wall Street to increase the service's user base.

I think I'd have resigned, too. It seems like a fairly unrealistic request which shows Wall Street is failing to respond to a changing online landscape.

Before I spend too much time bashing Wall Street, or defending Costolo, there are important things to know about Twitter. Despite revenue of $1.4 billion in 2014, the company lost $578 million. Although revenue was up 74% year-over-year in Q1 2015, the company missed targets. And Twitter has to face the reality that, although it has 300 million monthly users, more than 1 billion people have tried and didn't like Twitter. That's a lot of people not digging your product.

Here's the deal though: It is hard to look at increasing revenue and not see where, eventually, the lines cross and Twitter starts turning a profit. Monetizing a product and learning to stop spending like a startup aren't sexy. It takes hard work and a slowdown in your product growth.

It is hard to look at Twitter and not see a strong product. It's no longer a social platform but a media platform, a "What should I read now?" helper. I'll admit I hate the constant barrage of static on Twitter. Still, it accounts for 3.6% of the mobile Internet ad marketshare (compared to over 18% from Facebook and almost 37% from Google). The user base grew 18% in the quarter. The only critical thing one can see in these numbers is that Yahoo is poised to pass Twitter in US mobile advertising revenue. When Yahoo's comeback is better than your rise, maybe there are some problems.

Online media isn't the Wild West anymore. The days of companies rising from nowhere and having forever growth aren't sustainable. Let's say I was the CEO of an established company in an established industry, like maybe automotive. If I said my company's revenue was up 74%, my customer base increased 18% in the last quarter, and we were the third-biggest player in our industry, I'd get a raise.

To me, this is less an indictment of Twitter or Costolo than it is of a lack of understanding about where we are with online media, social media, and tech in general. Twitter isn't a startup. It isn't perfect either. Some good changes need to be made. But Twitter is, by now, a mature company in a mature industry. And its CEO should have been treated as such by Wall Street.
