Going Deeper
Who are you building your product/service for, and what painful problem are you taking away from their day?
(Answers provided by Jarek Sygitowicz) We’re building for companies in regulated industries that want to start accepting e-IDs in their KYC flows. If you want to accept digital IDs globally, you typically have to integrate with dozens of different wallets and banking APIs, each with its own quirks, maintenance protocols, and regulations. It’s a massive drain on engineering and compliance teams. We eliminate those headaches with one single hub. You integrate with us once and we handle the entire fragmented world of e-IDs, freeing you up to focus on other things.
If a top-tier VC is reading this, what would you want them to understand about your company in 30 seconds?
The e-ID shift is happening much faster than most people realize. The UK already has over 7 million users, and even traditionally conservative markets like the U.S. are moving quickly. Under eIDAS 2.0, every EU country must provide at least one official EUDI Wallet by 2026, and by 2027, regulated companies will have to accept them. We've already built the bridge that the entire market is now legally required to cross. It’s genuinely only a matter of time.
What are you doing differently than your competitors?
The industry was in a decades-long coma. Before COVID, nobody cared that much about remote identity. You had to show up in person at a branch or office. When lockdowns started, everyone rushed to digitize, but they did it the old way, which is to say using photos of IDs. That approach was always fragile. Now that GenAI enables anyone to generate fake documents, it’s completely untenable. Instead of trying to endlessly patch the old model, we’re helping move the identity verification industry toward a cryptographic, wallet-based future.

Jarek Sygitowicz (L), Krzysztof Klimczak, and Marek Rogozinski (R)
How did you meet, and why have you partnered with each other on this business?
Marek Rogozinski and I go way back. We met on an IRC channel in the late ‘90s and built a Linux blog together. I met Krzysiek Klimczak later when he was a VP at Toyota Bank. The three of us eventually founded and sold a company called ZenCard. We’ve stayed together because we have deep mutual respect and share a rare mix of skills. We’re all tech-minded and finance savvy. After building together for years, you develop a shorthand and a level of chemistry that makes solving hard problems easier. It works for us.
What was the “this has to exist” moment that made you start the company?
The moment came while we were building a Buy Now, Pay Later product for physical payment terminals. Everything worked—except the identity check. The cashier had to ask for a plastic ID, scan it, and manually type in the details, holding up the whole line of customers. It was terrible UX for everyone involved. We realized that for digital finance to really work, proving identity needed to be as simple as a contactless payment. The pandemic and lockdowns arrived shortly thereafter, bank APIs subsequently opened up, and Authologic was born.
How do you make money? Which part of your business model are you most excited about scaling?
We operate in a tier-based B2B model. What really excites me about scaling is our "Hub" concept. As government-mandated digital wallets become the norm in and beyond Europe, Authologic becomes the essential bridge between those wallets and the businesses that need them. We’re moving from being a tool to becoming the global infrastructure for digital identity. That’s what drives us.
Which proof points matter most right now?
Revenue growth is the most obvious and perhaps honest metric, and doubling ours last year is proof we’re on the right track. We’re backed by Y Combinator and our $8.2M Series A was a real vote of confidence. But the proof points that really matter show we’re shaping the industry. We’re part of the WeBuild consortium to develop the European Digital Identity (eUDI) standard. We also have several production-ready e-ID clients like OKX, eToro, and Santander—further evidence of the efficacy of our “e-ID first” approach.
How does your product/service make the world a better place?
Trust is the glue of society, and AI is currently nuking it. When you can’t tell if a person online is real or a bot, the foundations of both democracy and commerce start to crack. We want to restore and preserve that trust. By making e-ID verification easy, we help people prove they are human (and who they say they are) in digital interactions, whether they’re just posting on social media or opening a bank account. We’re building the missing trust layer that the modern internet so desperately needs.
What’s been your biggest unexpected challenge so far, and what did it force you to learn quickly?
We read the news. We know the world is changing very quickly, and, by extension, geopolitical tensions now shape product decisions in a way they didn’t ten years ago. Customers increasingly ask where our infrastructure runs, whether data touches U.S. cloud providers, and how easily we can move to EU-based hosting. Many prospects now prefer local vendors too. Hosting and data residency used to be purely technical choices. That’s no longer the case, and we’ve had to adjust accordingly. If you want to sell globally in 2026, you need to design for jurisdictional flexibility from day one.
What does success look like in 12 months? What about in 5 years?
Success in 12 months would be seeing our first batch of production clients using the new European Digital Identity (EUDI) wallets through our platform. We also want to multiply our revenue again.
In five years, we want Authologic to be the first name that comes up when a company anywhere in the world needs to verify a person online. We want to be the global standard for online trust.
What type of partner or collaborator would most accelerate your journey right now? (If relevant, which roles are you hiring for?)
We want strategic partners from companies in regulated industries who are searching for a better identity solution. We’re not fans of traditional reselling, but we love referral-based collaborations where we can truly add value. Anyone who believes the era of photographing plastic IDs is over should send us a message.

…we’re ringing the opening bell at the NASDAQ, knowing we’ve helped build a safer, more human internet.”
