Investing beyond Seed: Maria Koletsou on syndicate investing in the AI era

For decades, venture capital was highly inaccessible to most investors. Access to the best startup opportunities was often concentrated among a small group of funds, institutions, and experienced angels with established networks. Today, syndicate investing, secondary markets, and new investment structures are opening venture opportunities to a broader community of investors while creating new ways to participate in startup growth. 

At the same time, the venture ecosystem itself is evolving. Founders have access to more capital than ever before, liquidity is becoming a bigger consideration for investors, and artificial intelligence is influencing both the companies being built and the way investment decisions are made. 

To explore these trends, we spoke with Maria Koletsou, Founder of Blossom Ventures, an angel investing syndicate that brings together investors, operators, family offices, and founders to invest across private markets. Through its syndicate model, Blossom Ventures aims to make venture investing more accessible while creating a collaborative community where members can share knowledge, networks, and investment opportunities.

Who is Maria? Why did she start Blossom Ventures?

Before launching Blossom Ventures, Maria spent years working across financial communications, capital raising, and company building, helping founders, operators, and investors navigate fundraising and growth. Throughout her career, she worked on transactions that raised more than €3B, giving her a front-row seat to how investment decisions are made and how capital is allocated. But over time, she became aware of a recurring pattern: many talented founders, particularly women, struggled to access the right investors despite building strong businesses.

“I'd watched billions get allocated, and the pattern was consistent: the capital and the talent were structurally mismatched. At some point, watching that stops being interesting and starts being a waste. I wanted to be the one writing the check, not the one explaining it afterward.”

That realization ultimately led to the creation of Blossom Ventures. Rather than building another founder community, Maria saw an opportunity to address what she viewed as a capital infrastructure problem. The syndicate was designed to give more investors access to private market opportunities while creating a platform that supports founders across multiple stages of growth. Even the name reflects that philosophy. For Maria, Blossom represents growth as an ongoing process, one that often requires stepping outside familiar territory, learning new skills, and embracing uncertainty. As she describes it, growth is not always easy, but it is often where the most meaningful opportunities emerge.

“The name should reflect growth, a growth which sometimes is painful, but beautiful. Everything we do is outside the comfort zone: learning new things, investing in new territories, working with people you didn't know before. It's all a process, and Blossom totally reflects that.”

Since launching in September 2024, Blossom Ventures has continued refining its investment approach. What began as a mission to support diverse founders evolved into a broader vision: to become a long-term capital partner for companies throughout their growth journey.

Rather than focusing exclusively on pre-seed investments, the syndicate invests across the full company lifecycle, from early-stage startups to pre-IPO opportunities, and provides access to secondary transactions. For Maria, the first investment is not the destination but the beginning of a longer relationship, one that can compound through follow-on investments and eventually create liquidity for investors.

“Almost every female-led angel network in Europe stops at seed. We don’t treat the first check as the relationship; we treat it as the entry point, then compound through follow-on and engineer toward liquidity.”

As the platform matured, Maria says her own investment perspective evolved as well. Early on, much of the focus was on the founder sitting across the table. With greater deal exposure, however, she increasingly began looking at the factors that determine whether a company can successfully scale and ultimately generate liquidity.

“Early on, you over-index on the founder in the room. With more reps, you start seeing the structural questions earlier: cap table health, who the right co-investors are at the next round, and whether this company even has the architecture to reach liquidity. I’m a more structural investor now and a faster ‘no.’”

The lessons behind becoming a better investor

Like many investors, Maria's most valuable lessons came from her earliest mistakes. Her first angel investment, made more than two decades ago, became a crash course in what not to do. 

“I think, in this first investment, I've done everything that someone can do wrong when they start angel investing, and I've done everything at once. I wrote the first big ticket, not knowing that angel investing is a journey. I thought, you know, I have this money, I'm just going to invest all of it together and then wait, and miracles would happen. 

Mistake number one was concentrating the investment. Mistake number two was investing in an industry I didn't really know, but because it was glamorous. Mistake number three was that I knew the founders extremely well, so it was very difficult to suggest things because feelings were above common sense or business strategy.”

Rather than discouraging her, the experience pushed her to become a more disciplined investor. She spent years speaking with other angels, studying investment frameworks, and developing a more structured approach. Today, she believes successful investing depends less on access and intuition than many people assume and more on consistently applying a rigorous analytical process.

“Despite the fact that obviously I've lost money, and this was money that came from my work, the pain of losing it was huge. But looking back, about 25 years down the road, it was also a huge lesson because it helped me not make the same mistakes again. 

Losing on your first ticket can have two effects: either it discourages you and makes you forget about angel investing altogether, or it makes you ask yourself. How did I do that? I spent a lot of time talking to other angels, so I came back with a lot of knowledge of what I didn't know.”

That experience also influenced how she evaluates opportunities today. While access and networks matter in venture capital, Maria believes long-term success ultimately depends on discipline and analysis. Rather than relying on pattern matching or following popular narratives, she starts with a simple question: Is there a real problem being solved?

“Analysis is the fundamental. If you want to be a serious angel investor and build a portfolio over the years, analysis is what will keep you anchored. The first thing I'm always looking at is the numbers behind the problem and the solution. 

Sometimes people think they solved a problem, and the problem is not there. Or they think they have a huge, amazing solution, but it's not there. Before we look at the founder, we look at whether this is a true problem, whether this is a true solution, and whether the solution is sustainable and scalable.”

Investing in lines, not dots

Over the years, Maria has met many talented founders who struggled to raise capital, not because their companies lacked potential, but because they approached the wrong investors.

“When the first question a founder asks me is, ‘Tell me about your syndicate,’ that's a red flag. It means they don't know where they are and where they've landed. Not because we're special, but because this is time you're allocating away from your business.”

In many cases, Maria believes founders would be better served by having fewer, more relevant conversations rather than pursuing hundreds of investor meetings.

“It's actually better to have zero meetings if you cannot find your perfect match and focus on growing your business than to have a hundred meetings that are wrong. The opportunity cost is huge for the venture itself.”

For her, fundraising is not simply a numbers game. It is a targeting exercise. Founders who spend time understanding investor mandates, portfolios, and areas of expertise often achieve far better outcomes than those who pursue every available meeting.

“It takes a lot of research before you show up in a room. You have to be super prepared and super targeted. Sometimes I receive emails or LinkedIn messages from people who haven't spent a minute figuring out what my portfolio looks like, and that shows immediately.”

When she first started investing, like many angels, she often focused on the person sitting across the table: the quality of the pitch, the strength of the idea, and the immediate impression a founder created. 

“You invest in lines, not dots. A single meeting tells you almost nothing; it's one data point. The signal is the trajectory: how a founder updates their thinking between conversation one and conversation three, what they've learned, what they've stopped believing. Once I started evaluating the line instead of the dot, my judgment got materially better.”

According to Maria, every stage requires a different version of the founder. The skills that help someone launch a company are not necessarily the same skills required to scale it.

“We invest from pre-seed all the way to pre-IPO, and every stage has a completely different mindset of the founder. A founder might have a great idea and a very concrete plan, but they also need to be able to change the plan quickly if it doesn't work. They need to understand their blind spots, address them, and grow alongside their company. That's the line. That's the continuation process.”

For Maria, the most compelling founders are not those who appear perfect from day one. Instead, they are the ones who demonstrate continuous learning, self-awareness, and the ability to adapt as circumstances change.

“If you remain exactly the same as when we first met you at pre-seed, when you reach Series A or Series B, something doesn't work. Every stage changes the criteria by which we evaluate a founding team. But what is the line? The line is the continued growth of that founder to the point where they are self-aware enough to evaluate whether they are the team that can take the company all the way.”

That self-awareness extends beyond personal development. Maria believes great founders understand when they need help, when they need to bring new people into the organization, and when the company's success matters more than their own ego.

“Sometimes it's not the same people who take the company from one stage to another. It takes a brilliant founder to understand how far they can steer the boat, when they need more people to jump on board, and how to put the destination above their own ego. When that happens, big things happen.”

Why founders from emerging ecosystems stand out

As startup ecosystems across Southern and Eastern Europe continue to mature, Maria believes that one characteristic is increasingly setting many founders apart: adaptability.

Over the past decade, regions that once attracted relatively little venture capital have produced an increasing number of globally successful companies. While funding, infrastructure, and access to networks may have lagged behind more established markets, those constraints often forced founders to develop a different mindset.

“I think hungriness, however you define it, is super important. If you're not hungry, you can't succeed. 

Founders who build companies in resource-constrained environments often learn to operate with greater resilience, creativity, and determination. ”

At the same time, Maria believes the pace of change has made adaptability more valuable than ever. Markets evolve quickly, technologies shift, and problems that seemed important a year ago can become irrelevant surprisingly fast. In that environment, the founders who succeed are often those who can continuously learn, adjust, and evolve alongside the market.

“Think about it: what most founders were trying to solve a year ago might not be a problem anymore, and it's not their fault. There's continuous evolution, and to keep up with it, agility becomes increasingly important. The speed at which you adapt becomes critical.”
