Starting a business is a big achievement for many entrepreneurs, but maintaining one is the larger challenge. There are many standard challenges that face every business whether they are large or small. It is not easy running a company, especially in a fast-paced, ever-changing business world. Technology advances, new hiring strategies, and now, political changes coming with the new administration, all add to the existing business challenges that entrepreneurs, business owners, and executives have to deal with.

Maximizing profits, minimizing expenses and finding talented staff to keep things moving seem to be top challenges for both SMBs and large corporations. We have been interviewing companies from around the world to discover what challenges they are facing in their businesses. We also asked each company to share business advice they would give to a younger version of themselves.

Below is our interview with Phillip Merrick, CEO at SparkPost:

What does your company do?

SparkPost is the technology leader in email delivery. Our cloud-based software delivers over 30% of the world's legitimate non-spam commercial email for companies large and small, including banks, insurance companies, travel websites and technology companies.

What is your role? What do you enjoy most about your role?

I am the CEO of our company. There are two things about my role I greatly enjoy: one is getting to interact with our amazing customers and equally amazing team. The other is the sheer variety of my work day: in just a single morning I could be talking to a customer, then an investor, and then learning about a new feature we're planning to include in our cloud product.

What are the biggest challenges in your business right now?

For many years our company and our technology were like a well kept secret: only the world's largest senders of email knew about us. Now we make our email delivery service available to companies of all sizes who rely on email, and our biggest challenge is simply driving awareness and getting the word out.

If you could go back in time, what business advice would you give to a younger version of yourself?

I'd advise my younger self that there's not much in business you can't do if you apply yourself. For instance, I used to be afraid of public speaking; now I regularly speak to large groups and at conferences. And I probably could have struck out as a tech entrepreneur ten years before my wife helped me finally find the courage to do so.
