Everyone knows that starting a business is hard work, but I wish I had known just how much hard work it would be. In the beginning, it can be challenging to feel comfortable with that initial leap of independence—leaving whatever you were doing to start your own business. But the process after making the leap is what really proved to be testing.

Like many young startups, Fattmerchant was initially comprised of just me, myself, and I. However, after many late nights and lots of hard work, I eventually realized that it was time to recruit some help and start building a team. And while it’s definitely something I would consider to be a “champagne problem,” I never thought I’d need to do it.

At first, it was daunting to think of sharing what I had built with someone else. But talking with mentors helped me to understand that in order for Fattmerchant to grow, I could no longer handle everything on my own. A little over a year later, Fattmerchant is now a team of 17, and although I never realized how difficult building and managing a team would be, the company is stronger and kicking more butt than ever.

Everyone knows that running a business isn’t cheap. I was aware of the typical overhead, such as rent for office space, salaries, etc., but the little things, like office wine, keeping the pantry stocked, and supplying Universal passes for our entire team (to allow for team-building days), really add up. Balancing budget with my vision for the company has been a much more difficult task than I ever imagined.

There are so many moving parts that go into starting a business, and I quickly realized just how hard it is to make sure everything is properly taken care of. Perhaps the most difficult part of starting my own business was the sheer amount of paperwork that had to be done and submitted to the city. Although I had a few close calls, I was lucky to have mentors who walked me through the process and ensured that I had everything filed correctly.

Had I known just how hard starting Fattmerchant would be, I definitely would’ve tried to be more prepared.
