Financial services remains one of the most complex and opportunity-rich sectors for technology innovation. But building in fintech is rarely just about having a strong product. Founders also need deep market understanding, access to the right institutions, and the ability to navigate long enterprise sales cycles with precision.
In the latest episode of the Guts, Grit & Fintech Podcast, Vasyl Soloshchuk — founder and CEO of INSART — sat down with Mark Beeston, Founder and Managing Partner at Illuminate Financial, to discuss what it really means to be a specialist fintech investor. Since launching Illuminate in 2014, Mark Beeston has built one of the industry’s most respected fintech-focused venture firms. Today, the company manages roughly $500 million in assets, has backed more than 50 portfolio companies, achieved 10 successful exits, and built strategic partnerships with leading financial institutions across global markets.
Their conversation explores how Illuminate Financial supports fintech startups through its institutional network, what challenges financial services firms are most eager to solve today, how Beeston evaluates founders, and why coachability may be one of the most important traits in venture-backed leadership.
Building a Specialist Fintech Venture Firm
Vasyl:
Mark, Illuminate Financial now has more than 50 portfolio companies, 10 exits, and partnerships with some of the world’s most respected financial institutions. Can you walk us through the scale of the business today and how your investment thesis has evolved since 2014?
Mark:
When I started Illuminate more than eleven years ago, the focus was on building a venture firm dedicated to financial services and help founders solve meaningful problems inside the industry. Today, we manage around $500 million in assets under management. We operate from the world’s major financial centers, with partners leading the business from London, New York, and Singapore. Our team is a little over 20 people, with more than half focused directly on investing.
We are not the biggest venture firm in the world, but we are large enough to matter and specialized enough to be relevant. One of the biggest advantages of our position is that we operate in a part of fintech where the exit environment has historically been very trade-sale driven. Most of our successful exits have come through incumbent industry acquirers rather than public markets. That has meant exits to companies such as Bloomberg, PayPal, and more recently Carta, along with secondaries along the way. In an environment where many investors are still waiting for liquidity, we’ve been fortunate to keep distributions moving, which is important for everyone in the ecosystem.
Why Network Effects Matter in Institutional Fintech
Vasyl:
One of Illuminate’s clear strengths is its strategic network. You work with large financial institutions that can become customers, follow-on investors, and sometimes acquirers for portfolio companies. How does that network work in practice?
Mark:
The network is absolutely central to what we do.
I learned the value of institutional networks very early in my career, long before Illuminate. I joined Deutsche Bank as a graduate trainee just before its major fixed income transformation, and one thing that became very obvious was how much outcomes depend on knowing the right people and being connected to the right parts of the market.
When we launched Illuminate, we wanted to build on that idea deliberately. We were fortunate that our first fund was backed by what was then Markit, now part of S&P, and Deutsche Börse. Those institutions have gone on to anchor all four of our funds. Over time, we added more strategic LPs, including global banks and other major financial institutions. What makes the model powerful is that it creates a virtuous cycle. We talk with our partners under NDA to understand what challenges they are trying to solve for themselves and for their clients. We then share not only our portfolio, but also what we see in the market more broadly, so we can test ideas against real institutional demand.
That helps us become better investors because we understand not only where technology spend is today, but where it is going tomorrow.
The Strategic Value Illuminate Financial Brings to Founders
Vasyl:
So when you say “partners,” you mean institutions that are investors in your funds, potential customers for your portfolio companies, follow-on investors, and sometimes acquisition candidates. Is that right?
Mark:
Yes, exactly.
A good example is Citi. By the time Citi became an investor in one of our later funds, they had already directly invested in a quarter of the companies we had backed up to that point. We had made 32 investments, and Citi had already invested in eight of them.
That gives you a sense of how these relationships work in practice. The institutions in our network can play many roles. They can become customers. They can make follow-on investments. They can open channel partnerships. In some cases, they can become acquirers.
But the most immediate value is much simpler: warm introductions.
Institutional sales is hard. The cycles are long, procurement is complex, and the revenues are sticky once you win. What we can do through our network is dramatically improve the efficiency of that process. For an early-stage founder, walking into a major institution already recommended to the right person at the right time is enormously valuable. That sharpens the go-to-market motion in a way that is very difficult to replicate without trusted relationships.
The Biggest Trends in Institutional Fintech
Vasyl:
At INSART, we’ve been seeing several major trends in 2025: AI use cases becoming more practical, infrastructure players gaining influence, and more international fintechs trying to enter the U.S. market. What are the biggest trends and challenges you’re most excited to back right now?
Mark:
We are very thesis-driven, so the easiest way to answer that is to talk about the major windows through which we look at the market.
The original business was founded around what I believed was a generational transformation in financial markets infrastructure. Financial services had scaled on top of first-generation installed software for a long time, but after the financial crisis, the operating environment changed permanently. The sector became much more focused on cost, control, capital, and compliance. We saw deleveraging, a huge wave of regulation across jurisdictions, and effectively the emergence of a zero-tolerance compliance environment. That transformation is still ongoing, so there is still a huge opportunity in core infrastructure.
Alongside that, other generational shifts have emerged. One is the institutionalization of digital assets. Another is the transformation of private markets, private credit, and wealth management. Another is sustainable finance and the energy transition, which is creating new technology and data challenges across financial services.
And then, of course, there is enterprise technology targeting financial institutions, where the conversation is currently dominated by AI. Ten years ago, everyone wanted to talk about blockchain or data privacy. Today it is AI. The real work for us is separating genuine, sustained business value from temporary hype.
Why Infrastructure Still Matters
Vasyl:
We work mostly with B2B fintech startups building SaaS platforms or infrastructure, and this year we’re seeing more activity around infrastructure, APIs, integrations, and orchestration layers. It feels like the enablers are increasingly becoming the winners.
Mark:
That absolutely resonates. Financial institutions are enormous technology buyers, and their environments are inherently complex. That creates strong demand not just for front-end applications, but for the connective tissue that allows systems to work together more efficiently, more securely, and more compliantly. We have always invested in technology that solves real business problems for large institutions. So whether the solution looks like infrastructure, workflow software, orchestration, compliance tooling, or AI-enabled operations, the same principle applies: it has to create durable value in an institutional context.
We are not investing in technology for technology’s sake.
Illuminate’s Investment Stage and What Readiness Looks Like
Vasyl:
Illuminate is known for being thesis-driven, but stage also matters. Would you say your typical entry point is late seed through Series A, and now increasingly Series B with your early growth fund?
Mark:
Yes, that’s right.
Our original Ventures funds were very much focused on late seed and Series A. In practice, that usually means a company has a product, has begun to establish product-market fit, and ideally has some level of revenue to validate that. More recently, we launched our first Series B-focused early growth fund, and we have already made our first investments from that vehicle. At the earlier stage, what we like to see is some evidence of real commercial validation. Ideally that means production contracts. If there are several of them, that begins to suggest repeatable product-market fit.
We have invested in businesses with no revenue. We have invested in businesses that only had proof-of-concept work with production cutover potential. But naturally, we prefer situations where there is already some validated demand.
Why Team Matters as Much as Traction
Vasyl:
When you look at a startup at late seed, what convinces you they’re truly ready for investment?
Mark:
There are two big dimensions.
The first is the product side, which is where traction comes in. You want to see signs that customers genuinely want what the company is building, and ideally that the buying pattern could become repeatable. But the second dimension is just as important, and sometimes more important: the team.
You need founders with leadership, charisma, and a huge amount of internal energy. Starting a company means bulldozing through challenge after challenge after challenge. That requires a level of resilience and force of will that is hard to overstate. At the earliest stages, even if the product still evolves, those founder traits matter enormously.
What Mark Beeston Looks for in Founders
Vasyl:
When you first meet a founder, what are the positive signals that tell you they might be one of the few who can really scale?
Mark:
The single most important thing is whether you can have an honest debate with them.
That may sound simple, but it is actually very revealing. Assuming you are already screening for intelligence, energy, market understanding, and leadership, what really distinguishes great founders is whether they are coachable. And coachability does not mean they automatically follow whatever an investor says. It means you can have a real conversation. You can challenge assumptions, exchange perspectives, disagree productively, and they can process that information intelligently.
At the very early stage, if you can put difficult ideas into the conversation and the founder engages with them in an open, thoughtful way, that is a very good sign.
The opposite is also true. In many situations where companies later run into trouble, the issues were visible much earlier. The problem is not always that nobody saw them. Often it is that the founder did not see them, or refused to absorb what others were seeing. That is why the ability to assimilate new information matters so much.
What Coachability Really Means
Vasyl:
That’s a very important point. We’ve also seen cases where a founder is heading toward the wrong go-to-market strategy, and even when the warning signs are obvious, they remain convinced it will work. How do you tell whether someone is actually coachable?
Mark:
There is no completely foolproof mechanism.
At the end of the day, founders run their companies. Investors do not. That is part of what you are backing. But you can learn a lot from the quality of the interaction. I met a founder for breakfast recently, and what stood out was that he was just as interested in understanding our business as we were in understanding his. The conversation flowed in both directions. It was not just a one-way pitch.
That matters. Coming from a trading background, I think good decision-makers share a few traits: they are decisive, but they also assimilate new information quickly. When they realize a position is no longer right, they change it. Founders need a version of that same capability. They do not need to agree with every piece of feedback. But they do need to demonstrate that they can process it honestly and change course when the facts demand it.
Why Cap Table Quality Still Matters
Vasyl:
Illuminate typically targets 10% to 20% ownership stakes. What does that mean strategically for founders?
Mark:
This is fairly standard in venture. We are not unusual in targeting a meaningful double-digit position.
The principle is simple. Founders need to have enough equity that the upside remains highly motivating. In many cases, they are taking little or no salary in the early days, or they are earning far below what they could make elsewhere. Equity is the reward for taking that risk. At the same time, investors also need ownership that is meaningful relative to the outcome they are underwriting. We have walked away from businesses we genuinely liked because the cap table was structurally broken before we arrived and there was no realistic way to fix it. So this is not just a technical issue. A clean, workable cap table matters a great deal.
Leading Rounds vs Joining Rounds
Vasyl Soloshchuk:
Do you typically lead rounds or prefer to join alongside others?
Mark Beeston:
It depends on the fund and the situation.
Our third Ventures fund is our largest to date, at $235 million, which gives us the capacity to lead Series A rounds comfortably in our space. But we are also very happy to follow or co-lead if the situation makes sense. There is no corporate ego in that decision. What matters is getting to a position size that allows for a relevant outcome, which for us usually means 10% or more. In our early growth fund, we are probably somewhat more likely to follow or co-lead, simply because it is our first vehicle focused on that stage. The strategy is consistent. The entry point is just slightly later.
What Illuminate’s Early Growth Fund Changes
Vasyl:
You recently launched an early growth fund supported by strategic investors including S&P Global, HSBC, and NTT. What differentiates that fund from your earlier ones?
Mark:
The simplest answer is that these are just more mature businesses.
At the Series B stage, our rough definition is often $5 million or more in revenue. Sometimes companies call something a Series B earlier than that, but if they are only around $1 million in revenue, we would probably still view that as a Ventures-stage opportunity rather than an early growth opportunity. What changes at that later stage is the degree of repeatability. You want more validated sales, more mature operating metrics, and stronger evidence that the business is institution-ready. That last point is especially important for strategic partners. Compared with ten years ago, financial institutions have moved away from pure innovation theater. They care much more now about applied, pragmatic innovation that can be deployed inside the business.
Series B-stage companies are often much easier for large institutions to adopt. They are more likely to have the necessary compliance certifications. They are more likely to have gone through enterprise procurement and legal processes already. That makes them far more actionable from an institutional perspective.
A More Personal Side of Mark Beeston
Vasyl:
To wrap up on a lighter note: if you weren’t building and backing fintech startups, what would you be doing?
Mark:
That one is easy. Cars. I am a massive petrol head. I have a genuine passion for everything automotive. In fact, in the UK I set up, and still own and operate, my own car dealership. That was one of my first businesses. I make no claims about being a brilliant driver, but I absolutely love cars. That would definitely be the alternative path.
Final Thoughts
Illuminate Financial has built a distinctive position in venture capital by staying deeply focused on one of the most complex sectors in the economy: financial services.
As Beeston makes clear, specialist fintech investing is not just about identifying promising products. It is about understanding institutional demand, building trusted relationships with the world’s largest financial players, and helping founders navigate the realities of long enterprise sales cycles, compliance requirements, and market timing.
It is also about people. From coachability and decisiveness to resilience and honest debate, the qualities that define exceptional founders remain remarkably human, even in a market increasingly shaped by AI, infrastructure, and automation. For fintech startups building for financial institutions, that combination of domain expertise, strategic access, and practical judgment may be one of the strongest advantages an investor can bring.
