Pros
Mabbly has a lot of flash; Hank and Adam often talked about how the client agency needs to make the client jealous. "I want to work here!" is the immediate reaction anyone who comes in for an RFP should feel. There is free lunch weekly and weekly happy hour. As long as you are on Slack and delivering, people will always be fine with your work. You get to see real business negotiations your first week on the job.
Cons
Mabbly was built by an SEO wizard and his friends' sons. For most people at Mabbly, this was their first real job, so don't be surprised when your COO and head of sales are both younger than you. This is sometimes acceptable in Silicon Valley when working on emerging tech, but smb marketing takes a bit more than guessing and checking. Like most startups, the word hustle is important. Hank hustles daily and Vlad closes deals. But after that point, you are unsure who else is doing something. Titles get blurred behind buzzwords and with so much outsourced labor, everyone in-office essentially becomes a project manager. It becomes pretty hard to manage your clients also when your book of business is determined by favoritism. The Original Tribe, (all friends from the same clubs at DePaul) make sure to support each other and you'll be left to hang as there is limited process on who gets which project (and subsequently, who gets bonuses). Mabbly's biggest customer acquisition tactic started with their Wiley book. In their quest to find 500 interviews of great marketing, they also made 500 followup calls to ask if their interviewees would like to hire Mabbly. It sometimes worked, but after leaving Mabbly, you'll start to meet people who were left feeling like the interview was just to pitch the Mabbly Methodology. As a marketer, you don't want that kind of association; trust is all we have in this industry. You'll see in other reviews that ex-employees comment often on the ego of the leadership team. They are top tier salesman, they keep the company afloat. But in their minds, they are also the visionaries in the marketing world. No matter your title at Mabbly, understand that you'll be micromanaged. You are just executing the leadership team's vision. If you end up accepting your offer, be sure to start building your portfolio quickly. Mabbly will give you a lot to pad a resume with while you search for a job that pays market rate and has an insurance policy.
