Our Abridged Story


he story of Firestorm SEM started back in 2007, when Jonathan Stec wanted to start selling products online as a side business. He did well initially but was eventually forced out by those with much higher budgets and doing things like copying his sites, negative SEO, and even hacking (keep in mind this was a time when you could still run a Google Ad and show one URL yet send users to a totally different URL and when the more spam blog comment backlinks you had the higher you ranked). So, he decided he had enough and wanted to use his new found knowledge to help other businesses grow and took a position at GSI Commerce (now a part of eBay). There he gained big brand experience, working with brands such as GNC, Toys R Us, and Skullcandy.

Eventually he left GSI to pursue other ventures and ended up starting Firestorm SEM in 2011. Firestorm SEM quickly grew into a top SEM agency in Philadelphia, working with local clients such as Rutgers Camden, regional brands like Revelator Coffee, and international brands like Verizon. Firestorm SEM has been a Top SEM Agency in Philadelphia for the past 4 years (rated by Clutch), is a Premier Google Partner (top 1% of Google’s trusted service providers), and is routinely a Top Rated agency on Upwork.

Our Agency


irestorm SEM is headquartered in King of Prussia, PA in the Valley Forge Casino. Despite this, Firestorm SEM is still mostly a virtually based agency, meaning that most of the work is done remotely. In this day and age, we do not see a need to have a large, expensive office that wastes resources and increases costs for clients. With the direction the world is going (wireless, digital, tech) a virtual operation only makes sense. And the team behind Firestorm SEM loves the freedom that a virtual approach brings while not feeling like they need to be in an office in order to get work done.

Despite being a virtual agency, things like Skype, Snapchat, and even the good old fashioned phone allow us to stay connected and have that face-to-face time. We still make time to get together when possible and celebrate the important things. The virtual model has never hindered our work and has never been a weakness. We find that it is not only a strength but also puts us ahead of the curve and trend of what agencies will eventually adopt.

Jonathan actually enjoys this SEO and PPC stuff! And when he isn’t working with clients or his own brands, he is spending time with friends, family, and his dog. He is a classic 16 bit Nintendo connoisseur and spends way too much time in the gym, running trails, and swimming where ever he can.
