Inspiring Conversations with Erik Mesikäpp of Aggregatemarkets.com

Today we’d like to introduce you to Erik Mesikäpp.

Alright, so thank you so much for sharing your story and insight with our readers. To kick things off, can you tell us a bit about how you got started?
My story begins in a small but tech-savvy country tucked away in Northern Europe—Estonia. It’s a place known for its digital-first government, medieval cities, cold & icy winters, and one of the highest numbers of startups per capita in the world (also referred to as a Startup capital of EU). Both parents being entrepreneurs, the spirit must’ve rubbed off on me early.

Back in 2015, while I was still a university student studying International Relations, I started what would later become a largest dump truck company in Estonia—almost by accident. I was doing side hustles in construction with friends to earn some extra income. One day, we just took the leap and bought our first small dump truck.

At first, it was just a side hustle—helping deliver sand, gravel, and other bulk materials around my hometown. But things grew. Fast. We founded Isekallur OÜ, and over time built it into Estonia’s first and largest mineral and aggregate e-commerce platform. We weren’t just delivering material anymore—we were digitizing the industry.

We make it easy for people to order bulk construction materials online, without the old-school phone calls and guesswork.

I always felt a connection with the United States. Even as a kid, I saw the U.S. as a place of opportunity —where ideas grow faster and bigger.

That feeling came full circle when I met Chris, expert in the U.S. construction scene. Together, we realized the problems we solved in Estonia—confusing pricing, outdated ordering systems, manual brokering—were just as real (if not worse) in parts of the U.S.

So with the help of Chris, our American side co-founder, we launched AggregateMarkets.com, the U.S. version of our e-commerce model for bulk materials. Last year, we officially went live and started doing business in five U.S. states, including Tennessee, which has quickly become our top market, followed closely by Indiana.

We’re not just moving bulk materials—we’re building a digital infrastructure for the next generation of logistics and construction in America. From a single truck in Estonia to a tech-backed, multi-state operation in the U.S.—this journey’s been wild, and it’s just getting started.

Alright, so let’s dig a little deeper into the story – has it been an easy path overall and if not, what were the challenges you’ve had to overcome?
Not at all. Building a business from scratch—especially in an industry as traditional as trucking and construction—is never easy. When we started Isekallur, we had no investors, no fancy connections, and no playbook. Just one truck, a lot of ambition, and long nights spent juggling university studies with client calls, deliveries, and fixing the truck ourselves when it broke down (which it often did).

We had to earn the trust of old-school contractors who didn’t understand (or believe in) ordering gravel online. At times, I felt like we were trying to sell the future to people stuck in the past. There were moments we nearly ran out of cash. There were winters so brutal that trucks wouldn’t start and materials froze solid in the bed. But we adapted. We learned how to work with the seasons, not against them.

Then came the next big challenge—expanding outside Estonia. Going international isn’t just a matter of language and logistics—it’s mindset. The U.S. was the dream, but it’s a whole different animal: more competition, higher stakes, bigger distances, and different regulations.

Still, the hardest part wasn’t the scale—it was breaking into a market where no one knew us and bootstrapping with very minimal budget. We weren’t the sons of trucking dynasties. We were guys with a crazy idea that we could digitize an entire industry. People laughed. Some ignored us. But slowly, with the help of our U.S. co-founder Chris and some bold early partners, we proved it could work.

And that’s how AggregateMarkets.com started getting traction—by solving real pain points for homeowners & businesses: transparent pricing, fast quotes, verified truckers, and materials delivered without the endless research and going back-and-forth.

Thanks for sharing that. So, maybe next you can tell us a bit more about your business?
At its core, AggregateMarkets.com is an online marketplace that makes it easy to buy gravel, sand, topsoil, mulch, and other bulk construction materials—something that sounds simple but is notoriously difficult and outdated in most parts of the U.S.

We specialize in digitizing the bulk materials industry. That means no more endless phone calls, unclear pricing, or wondering where your delivery is. With just a few clicks, contractors, landscapers, and even homeowners can get real-time prices, choose their material, and have it delivered—fast.

What sets us apart is that we’re not just a listing platform—we’re a full-stack logistics solution. Our tech connects customers with the nearest quarries and local truckers, all while seamlessly handling logistics, payment, and order tracking in the background. It’s like Uber meets Home Depot, but for bulk materials.

What are we most proud of?

We’re proud to say we were the first company in the European Union to bring this kind of e-commerce experience to the dump truck world, and now we’ve launched in the U.S., currently operating in five states—with Tennessee and Indiana being our most active markets. Our team is small but battle-tested. We’ve lived this problem—we’ve driven the trucks, loaded the gravel, answered the late-night customer calls. That’s why the tech we’ve built is practical, not flashy. It actually works for the people in the field.

Can you tell us more about what you were like growing up?
I’d say I was probably more of an introvert than an extrovert growing up. I wasn’t the loudest kid in the room, but I was always curious—especially about history, strategy, and how things worked. I did well in school, especially in subjects like history, and I loved spending time alone or with close friends, playing video games or watching documentaries.

Outside of that, I was surprisingly active. I was a strong swimmer as a kid, and around the age of 12, I got into motocross, which became a big passion of mine. There was something about speed, control, and the challenge of the track that kept me hooked. Then came gym. But as you can see, a lot of solo hobbies. Lol..

I was also one of those kids who was drawn to military & history stuff—books, games, documentaries. At 17, I decided to take it further and joined the Estonian Defence League, which is kind of like a national guard. I went through basic military training, and it taught me a lot about discipline, responsibility, and pushing through when things aren’t easy.

Looking back, I think those early years really shaped how I approach business today—focused, not afraid of hard work, and always thinking tactically.
