In 2006, Domingo joined Telefónica, initially overseeing its research and development operations in Barcelona. Over the following years, he held multiple leadership roles within the company, including Director of Product Development and Innovation, and later CEO of New Business and Innovation at Telefónica Digital. He also held board positions at affiliated companies such as TokBox, Tuenti, Jajah, and was involved in the founding of Wayra, a Telefónica-backed initiative focused on early-stage ventures.

Between 2014 and 2017, Domingo worked in the Gulf region, first as Chief Product and Business Development Officer at Etihad Etisalat (Mobily), and subsequently at the telecommunications firm du, where he managed areas related to digital services, data analytics, smart cities, and emerging technologies.

Securitize and BUIDL

Carlos Domingo co-founded Securitize, where he serves as CEO, leading the company in developing compliant digital securities platforms. Securitize's primary mission is to transform how companies raise capital and manage investors by bringing real-world assets on-chain through tokenization. The company has established itself as a prominent player in the digital asset space, recognized as a 2025 Forbes Top 50 Fintech company. As of May 14, 2025, Securitize manages over $4 billion in assets under management (AUM) in tokenized real-world assets.

Under Domingo's leadership, Securitize has partnered with major asset managers such as Apollo, BlackRock, Hamilton Lane, and KKR to tokenize funds. Securitize, through its subsidiaries, operates as a SEC-registered broker-dealer, digital transfer agent, fund administrator, and operator of a SEC-regulated Alternative Trading System (ATS), ensuring regulatory compliance in its operations.

A significant achievement for Securitize and Domingo is their role in the BlackRock USD Institutional Digital Liquidity Fund (BUIDL). Securitize tokenizes BUIDL, which was launched in March 2024 as BlackRock's first tokenized fund on a public blockchain. BUIDL quickly surpassed $1 billion in AUM, marking a key milestone in the development of the tokenized treasury market.

BUIDL provides qualified investors with on-chain access to U.S. dollar yields, featuring flexible custody, daily dividend payouts, and near real-time 24/7/365 peer-to-peer transfers. In June 2025, BUIDL was accepted as collateral on two major crypto exchanges, Crypto.com and Deribit, further integrating it into the crypto market infrastructur.

Domingo commented on this development, stating, "With BUIDL now accepted as collateral on Crypto.com and Deribit, the fund is evolving from a yield-bearing token into a core component of crypto market infrastructure. Tokenized Treasuries are being actively used to improve capital efficiency and risk management across some of the industry's most sophisticated trading venues, while still offering yield".

BUIDL's reach has expanded to seven blockchains, including Aptos, Arbitrum, Avalanche, Ethereum, Optimism, Polygon, and Solana, with cross-chain interoperability facilitated by Wormhole. This expansion aims to offer increased optionality and access for investors, decentralized autonomous organizations (DAOs), and other digital asset-native firms. Custodians supporting BUIDL investors include Anchorage Digital, Copper, and Fireblocks, with Bank of New York Mellon serving as the fund's cash and securities custodian.

Regarding the expansion to Solana, Domingo noted, "In the year since BUIDL’s launch, we’ve experienced significant growth in demand for tokenized real-world assets, reinforcing the value of bringing institutional-grade products on-chain. As the market for RWAs and tokenized treasuries gains momentum, expanding BUIDL to Solana, a blockchain known for its speed, scalability, and cost efficiency, is a natural next step". ^{[1] [3] [4]}

Interviews

Tokenization and Financial Infrastructure #01

On December 23, 2024, Carlos Domingo appeared as a guest on the DeFi Decoded podcast, hosted by Alex Tapscott and Andrew Young and published by Ninepoint Partners. The discussion focused on developments in the tokenization of real-world assets (RWAs), regulatory considerations, and the relationship between blockchain technologies and traditional financial systems.

During the interview, Domingo outlined his view that tokenization extends beyond operational efficiency, enabling new transaction models such as peer-to-peer transfers, expedited settlement processes, and compatibility with stablecoins and decentralized finance (DeFi) mechanisms. He stated that regulatory compliance and licensing are necessary components for broader institutional participation. In this context, he referenced Securitize’s registration as a broker-dealer and digital transfer agent, which facilitated collaboration with financial institutions including BlackRock and KKR.

The conversation also addressed the role of stablecoins and tokenized currencies in improving liquidity and transaction efficiency within tokenized markets. Domingo noted the importance of operating across multiple blockchain networks and utilizing cross-chain infrastructure as a way to support broader accessibility and functionality. He further indicated that privacy-preserving technologies, including zero-knowledge proofs, may become increasingly relevant for institutions that require confidentiality while maintaining regulatory standards.

Drawing on his earlier experience in the telecommunications sector, Domingo described parallels between infrastructure development in both industries. He suggested that the future expansion of RWAs may depend on regulatory clarity and the capacity of legacy financial institutions to engage with blockchain-based models. He estimated that the market for RWAs could expand significantly over the next five to ten years, contingent on policy developments and technological adoption. ^[6]
