Managing Partner of Adventures Lab Ruslan Tymofieiev Tells About Working With Startups

Ruslan Tymofieiev’s entrepreneurial journey began with a student idea that grew into a successful business. What started as a student side project eventually grew into Everad, a CPA network specializing in the Health & Beauty sector.

After exiting the company, Ruslan shifted focus from operations to investments, laying the foundation for what would become Adventures Lab, a venture fund now backing some of the most prominent startups in Eastern Europe. Its portfolio includes names like Reface, SALO, EduDo, StreamHero, Narrative BI, and, more recently, the creative-tech platform Pibox. The investor shared how his investment journey began, how he approaches startup selection, and what drives the long-term strategy behind Adventures Lab.

How Ruslan Tymofieiev Took His First Steps into Investing

Ruslan Tymofieiev’s interest in investing began long before his first deal — it was a field that had always intrigued him. He started making his first startup investments in 2014, even as he was still actively growing Everad — a CPA network he had co-founded just a year earlier. Alongside scaling that business, he began exploring opportunities in early-stage startups.

One of his earliest investments was in a Kyiv-based taxi service — a concept similar to Uber. However, the project ultimately failed. Ruslan Tymofieiev claimed that the founding team treated the startup more like a technical prototype than a real business. He recalled that the founders assumed launching an app alone would be sufficient, overlooking the operational complexities required to sustain and scale the business. Then the team understood that this is an operational business, and an interface alone doesn’t drive success.

The financial loss from that first venture, estimated at under $100,000, wasn’t critical for him, but the lesson was valuable. He went on to invest in several other projects that also didn’t fully take off. Still, Ruslan views those early experiences as essential. He believes that going through early failures is a necessary part of becoming an investor, noting that those setbacks taught him more than any early success could.

Key Criteria Ruslan Tymofieiev Looks for in a Startup

According to Ruslan Tymofieiev, novice investors should begin not with money but with knowledge. Before making any financial commitments, he believes it’s essential to study the experiences of others. He argues it’s far more effective — and less costly — to learn from others’ mistakes than to repeat them yourself.

Reflecting on his early investment attempts, Ruslan Tymofieiev openly acknowledges the mistakes he made. His early mistakes included making emotional decisions, investing without thorough due diligence, and overestimating both the market potential and the founders’ abilities. He explained that he simply liked the idea, so he invested — that’s a fundamental error. Ruslan admitted that early in his journey, he backed the first project that seemed promising, without a full analysis of the market, competition, or long-term viability.

Today, his approach is far more rigorous: at Adventures Lab, only one or two startups are selected for funding out of every hundred reviewed. While founders still occasionally approach him directly in search of immediate investment, Ruslan stresses that all decisions are now based on a detailed and structured due diligence process. Looking back, he admits that some of the fund’s earliest deals would not meet the current selection criteria.

When evaluating a startup, Ruslan Tymofieiev starts with the market, not the team. He studies the niche in depth: its size, maturity, level of competition, and growth potential. Only after confirming that the market offers a real opportunity does he turn to assessing the founder’s capabilities and level of competence. In Ruslan’s words, a startup can only succeed if both the market and the people behind it are strong.

What Strategy Does Adventures Lab Follow?

In his investment philosophy, Ruslan Tymofieiev places equal weight on product quality and market dynamics. Through his venture fund, Adventures Lab, he often encounters startups with impressive teams, solid execution, and polished products, yet they still get turned down because of market limitations. The entrepreneur recalls a case where a startup checked every box in terms of execution. However, a deeper market analysis revealed that the total profit potential in their chosen niche was limited to just $30,000. Adventures Lab avoids oversaturated or stagnant sectors, instead prioritizing startups operating in fast-growing markets that still offer room for expansion.

When evaluating founders, the investor prioritizes competence and replaceability, as he views these traits as markers of resilience. This was the case with Reface, one of Adventures Lab’s most high-profile investments, where the company successfully navigated a change in leadership. Beyond operational skills, a founder’s network is another critical factor. Strong communication skills and a wide network of contacts provide entrepreneurs with faster access to insights, partnerships, and talent, ultimately enabling them to make better, quicker decisions.

While Ruslan Tymofieiev recognizes the importance of emerging trends like artificial intelligence, he remains cautious about making investments driven purely by hype. He emphasizes that Adventures Lab prioritizes sectors where the team has deep expertise, rather than simply following market buzz. At the same time, he doesn’t dismiss any category outright. In his view, even seemingly saturated niches can present unexpected opportunities, particularly when driven by a visionary founder capable of unlocking hidden potential.
