Let me share my journey—what it took to build this company and the personal challenges and growth that shaped the path to where I am today.
2011 – 2015
It all started in 2011 during my university days studying banking. All I can remember from that time is my love for the web. I was learning how to code and build websites daily, gaining hands-on experience and improving my skills.
After graduating, I immediately landed a job at a bank in Minsk, Belarus. Though I was selling financial products to business clients during the day and at night, I continued building websites. I was so passionate about websites that I started to run my own website development agency. Sadly, this didn’t last for long because I had to join the army.
2016 – 2017
You see, I’m from Belarus, where military service is mandatory for every man. I served for 12 months, but I made every spare moment count by honing my skills. It was during this time that I realized something crucial: building a website isn’t the real business—it’s driving its growth that truly matters.
Every second night on duty, I immersed myself in learning about conversion rate optimization, web analytics and digital marketing. I devoured every printed resource that I received from my mother by post office about data analytics, growth hacking, and paid marketing. I’ve never been one to waste time, and this experience cemented that mindset even further.
After completing my service, I quickly secured a role at a CRO agency. All that learning I did would finally come in handy. I implemented analytics tools like Kissmetrics, Google Analytics, and Hotjar, analyzed clients’ data, and proposed A/B testing ideas. But after six months I felt like I couldn’t gain anything more from that job so I left to begin my freelancing journey.
My freelancing journey began on Upwork in partnership with a friend. Together, we provided CRO, analytics, and data analysis services. Two years later, I launched my own Upwork profile, fully capable of doubling a company’s revenue through experiments, traffic analysis, and onboarding optimizations. In only 3 months I received the “TOP Rated” badge on Upwork and my clients were referring so much that I stopped relying on the platform for new clients.
One client in particular, Provably Fair, was so happy with my work that they hired me full-time. The company was sold eight months after I got hired but in January 2021 I started to work on Mailbird.
There, I expanded my skill set significantly. By using A/B split testing, data analytics, and machine learning techniques, I improved the lifetime value of customers by 58%. My results earned me a promotion to CRO & Data Manager.
Mailbird was a fantastic experience, but I wanted to expand even more companies. I wanted to help SaaS businesses on a broader scale. That’s why I left to found the Vakulski-Group.
I launched Vakulski-Group with one goal in mind: to help small and medium SaaS companies reach 7 figures.
Today, my team includes 12 highly skilled professionals specializing in project management, UX/UI design, development, testing, analytics, and data engineering. Together, we deliver tailored strategies and actionable insights to help SaaS businesses grow smarter and faster.
And we are now waiting to help you grow your business.
“Unlike others, Ihar’s team did a fantastic job for us. Firstly, they helped us set up Mixpanel and define and track key SaaS metrics such as retention, churn, stickiness, adoption rate, trial-to-paid, and many-many others. Secondly, they focused on understanding our customers and conducted extensive user behavior research. We believe this actually helped their online experiments to show regular impressive boosts like 70% in conversion rates across many funnel stages and product features.”

“I could write a long review about what we got out of using these services, but I'm sure the following will cover it quite well. In a few days, we earned back what we paid Ihar’s team for by following their recommendations. They tested our order flow in our SaaS and pointed out a lot of friction - my only regret is that we didn't hire them a long time ago.”

"Working with Vakulski-Group has revolutionized how we approach analytics for the NoblePro app. Before meeting them, we struggled to track user behavior and understand feature performance. They expertly implemented Mixpanel, set up dashboards for monitoring key metrics, and trained our team to use the tool effectively. Thanks to their expertise, we now have actionable insights that drive our decisions. I highly recommend Vakulski-Group for anyone looking to elevate their product analytics.
