In this episode, I sit down with Lorenzo Romagnoli, co-founder of USDT0.

USDT0 is the interoperability layer for Tether's USDT. A smart contract on Ethereum locks USDT and, through LayerZero, the equivalent USDT0 is minted on the destination chain, so users can move USDT across more than 25 blockchains without third-party bridges or fees. Developed by Everdawn Labs in partnership with Tether, USDT0 launched in January 2025 on Kraken's Ink and has since processed more than $100 billion in cumulative volume. The same team also runs XAUt0, the omnichain version of Tether Gold.

Lorenzo is one of USDT0's three co-founders. He studied economics and finance at Queen Mary University of London, got into DeFi in 2020, and has spent the last years building within the Tether ecosystem. He is based in Lugano.

We talk about why Switzerland attracts so many crypto companies, how USDT0 works and who uses it, a business model where blockchains are the clients, becoming profitable without raising a round, working with Tether, how regulation changed the stablecoin market, whether payments will move to stablecoins, and why stablecoins matter most in emerging markets.

In this episode, I sit down with Andrej Benčić, co-founder and CEO of Tenderly.

Tenderly is a blockchain development and operations platform built around the Ethereum ecosystem. Founded in 2018 in Belgrade, it started as a debugger that explained why a transaction failed and now provides simulation infrastructure, monitoring and developer tooling for teams building on-chain, from protocols to financial institutions managing capital. Tenderly has raised $58.6M, most recently a $40M Series B led by Spark Capital in 2022, with Accel and Point Nine Capital backing its earlier rounds.

Andrej, a software engineer by background, founded Tenderly with Bogdan Habić, Miljan Tekić and Nebojša Urošević after years of building projects together at hackathons.

We talk about how simulation helps developers, products and institutions manage on-chain risk, why the space needs adoption more than new innovation right now, raising in 2021, navigating bear markets, Ethereum as the "JavaScript of blockchain", a multi-chain future, stablecoins and the digital euro, and hiring talent globally.

In this episode, I sit down with André Silva, co-founder and CEO of Quartz.

Quartz is a London-based AI personal banker. It connects users' bank, broker, pension and ISA accounts in one place, and its AI assistant, Charlie, turns that data into personalised insights on their wealth. The company launched in the UK in September 2026 alongside a £2.75M pre-seed round led by Daphni, with participation from Outward VC, K Fund and angels including Philippe Gelis and Gilles BianRosa.

André founded Quartz in 2025 with Mateus Mesquita Alves, former Investment Product Lead at N26. Before that, he spent six years at Revolut as Head of Global Expansion, responsible for new market launches and the group's international P&L. He started his career in M&A at HSBC in London and in equity research at BPI in Portugal. He holds an Economics degree from Porto University and an MSc in Finance from ESADE.

We talk about why financial advice is priced out for most people, why open banking covers only a small share of people's wealth, what UK investors actually hold, raising a pre-seed round, and where human advisors fit once AI does most of the work.

In this episode, I sit down with Ertan Can, founder of Multiple capital.

Multiple Capital is a micro-VC focused fund of funds that invests in VC funds in Europe and the US. They seek out innovative, emerging fund managers (teams and solo) in niche geographies and verticals that are often overlooked and inaccessible for many investors.

It's a unique perspective on how an investor decides on which funds to invest, and consequently on how VC managers drive their decision process.

With Ertan, we will discuss the VC industry in Europe, on how to choose a fund, and what the European startup ecosystem is missing to catch up the gap with the US.
