The founder behind DIDO

Hi, I'm Roman. This is how DIDO started.

I was born in Western Ukraine, learned eCommerce in Belgium, and started over in New York with $5,000. DIDO grew out of all of it.

I'm not a fan of polished founder bios, so here is the short, real version, and why we chose to do one thing well: email and SMS.

My story, in short

How I got from Western Ukraine to email marketing in New York.

2014Ukraine and Belgium

Where it started

I was born in Western Ukraine and studied finance at university there. In 2014 I moved to Belgium and joined a company that sold disposable tableware, a whole catalogue of it.

I built their website and started selling those products online. That is where I learned how eCommerce really works: product pages, orders, and getting customers to come back and buy again. Belgium is also where my family story began. Every step after that, I took with their support.
2018New York and Upwork

Starting over with $5,000

After winning a Green Card, we moved to New York with about $5,000. While I looked for work, I built websites, and then I took my first email marketing client on Upwork, at $20 an hour.

The reviews added up, bigger brands followed, and Upwork featured me among its top-rated Klaviyo specialists. Every founder I talked to said the same thing: nobody is great at everything. So I stopped trying to be. I picked email.
2019DIDO team and OSSA Frames

From freelancer to team, and a store of my own

Clients started asking us to run the whole channel, not just set up a few flows. DIDO became a team: designers, account managers, and native English copywriters.

The same year I co-founded OSSA Frames, a designer eyewear business that began with one box of glasses and now works with around 150 brands. Running my own store means I see email from the owner's side too: inventory, margins, and customers who want answers now.
2020Family

Becoming a dad

Our son Daniel was born. Having a family behind me changed how I work: I want every hour to count, for us and for the people we work with.

It is also why we set DIDO up so a founder spends about 30 minutes a week on email with us, not 30 hours.
2022–2025Awards and the stage

Recognition, and a lot more speaking

In 2022 Top USA Awards named me one of the Top 100 U.S. entrepreneurs with Ukrainian origin. Since then DIDO has been recognised on Clutch, including Global Top 15 email marketing agencies in Fall 2025 and Spring 2026, with a 4.9/5 client rating.

Speaking became part of the work. I have talked about email marketing at the Big Money Forum in New York and Board NY, led email marketing workshops, and joined industry events with Klaviyo and Attentive.
TodayEmail, SMS and AI

Building with AI operators and agents

Email and SMS are still the core of what we do. Now we are also working on AI operators and agent integrations, so routine work runs on its own and our team spends its time on strategy and creative.

What all of that turned into

What working with us actually feels like.

You spend about 30 minutes a week You tell us yes or no. We take care of the strategy, design, copy, setup, testing, and reports.
We look at sales, not just opens Opens and clicks tell us something. Revenue and customers who come back tell us much more.
We'll tell you what's missing If email isn't the problem, we say so, and we introduce you to people we trust.
We're in it for the long run We've been a Klaviyo partner for years and hold Gold status. Good email programs grow over years, not weeks.

“The goal has never been to send more email. It is to give every customer a reason to come back, and every founder more confidence in their next decision.”
