Between Data and Risk is for founders who are actually building something. After nearly 50 episodes on data, risk, and business ops with corporate leaders, we shifted focus—because the stories that stuck weren’t about scale. They were about the early days, when everything’s uncertain and nothing works yet. Now we talk to founders making real decisions with limited info, tight time, and no safety net. The problems vary, but the terrain is shared: shipping too early, hiring too safe, trusting your gut and hoping you’re right. Your hosts: Artur Guja, ex-CRO and ex-trader who navigated 2008 with gains. Dr. Marian Siwiak, scientist, data whisperer, author of Data Mesh in Action, and creator of artificial sentience. Together, they wrote Starting Data Analytics with ChatGPT. And they still enjoy what matters most: talking to founders figuring it out as they go. Subscribe if you want to learn what works (and what doesn’t) from people who’ve lived it.

What if blockchain isn’t just about coins and speculation—but about real, everyday utility?
In this episode, Dr. Marian Siwiak talks with Lorien Gamaroff @Gamaroff a blockchain pioneer and the founder of Centbee, about how Bitcoin technology can enable true financial inclusion across Africa. Lorien shares the story behind Sentby, a mobile money platform built on Bitcoin that’s leapfrogging traditional banking systems and giving people without access to banks a way to store and send money.
They explore the shifting purpose of Bitcoin—from digital cash to digital gold—and dive into why Lorien believes Bitcoin Satoshi’s Vision (BSV) holds the original promise of utility, low fees, and governance. From the cost dynamics of blockchain to regulatory compliance and the future of NFTs, this conversation challenges crypto orthodoxy and reclaims blockchain as the missing protocol of the internet.
This one is for anyone wondering: what happens when ideology meets infrastructure?
Takeaways:
- Financial inclusion is key to Africa’s future—and blockchain might be the unlock.
- Bitcoin was originally designed as a governable, compliant cash system.
- BTC’s decentralization ideology has pushed it toward digital gold, not utility.
- Mobile money in Africa is leapfrogging traditional finance.
- Sentby is building a blockchain-powered “super app” for financial access.
- BSV aims to return to Bitcoin’s original design—low fees, scalable, useful.
- The value of Bitcoin lies in utility, not speculation.
- Blockchain can empower data ownership, not just digital currency.
