About Prometheum
Prometheum is a US-based platform focused on compliant digital asset securities. Its core business covers the full lifecycle of digital asset securities: helping issuers issue tokenized securities, providing qualified custody services, offering correspondent clearing for broker-dealers, and operating an alternative trading system (ATS) for secondary trading. All of these services operate under SEC and FINRA regulatory frameworks.
The company's key narrative is "compliance as infrastructure." Unlike many crypto platforms that operate in regulatory gray areas, Prometheum builds its technology and services to fit within existing US securities laws. This positioning aims to solve a real market pain point: traditional financial institutions want to engage with digital assets but are hesitant due to regulatory uncertainty. Prometheum provides a bridge, allowing broker-dealers and RIAs to offer crypto and tokenized securities to clients through familiar, regulated channels.
In the past six months (February to August 2026), Prometheum has made notable progress. In July 2026, it launched Digital Brokerage Solutions, a suite of correspondent clearing and custody services, and announced Velocity Capital as its first public client. This marked the first real commercial adoption of its clearing model. The company also completed a DTCC tokenization demonstration, proving its custody platform can interoperate with existing financial market infrastructure.
However, challenges remain. Critics have questioned whether there is sufficient commercial demand for SEC-regulated crypto brokerages, especially after regulatory clarifications classified many major cryptocurrencies as commodities rather than securities, narrowing the asset pool Prometheum can handle. The Velocity Capital announcement also lacked details on asset types, trading timelines, and production readiness, leaving questions about scalability.
Prometheum's development path centers on building SEC-compliant digital asset securities infrastructure. Key milestones include: 2023, becoming the first SEC-registered Special Purpose Broker-Dealer (SPBD) for digital asset securities custody; 2024, completing a $20 million financing round and later acquiring SEC/FINRA-registered broker-dealer ProFinancial to enter the U.S. RWA market; 2025, raising an additional $23 million; 2026, completing its first crypto transactions (ETH) and launching a digital brokerage solution enabling traditional brokerages to directly offer tokenized securities. These steps progressively established its compliant custody, clearing, and trading ecosystem, though the post-Gensler regulatory shift has weakened its earlier compliance-first advantage.
Past six months: In May 2026, Prometheum Capital launched Digital Brokerage Solutions, enabling broker-dealers and RIAs to offer crypto assets through traditional brokerage accounts. It cleared and settled the first ETH transaction directly in a U.S. brokerage account (not via ETF/ETP). Initial clients included Arete Wealth, Network 1 Financial Securities, and an unnamed clearing broker-dealer. Later, Velocity Capital became the first publicly disclosed omnibus clearing client.
Future focus: Prometheum aims to scale tokenized securities and crypto via Wall Street distribution, expecting more broker-dealers and RIAs to join soon. Services currently center on ETH, with plans to add more digital assets. It is also preparing Prometheum ATS for secondary trading, completing a full lifecycle from issuance to custody, clearing, and trading.
Prometheum was co-founded by Aaron Kaplan and Benjamin Kaplan, both serving as Co-CEOs. Aaron has a legal background, having worked at Gusrae Kaplan Nusbaum LLP, focusing on blockchain securities law; Benjamin also has legal experience, having practiced at the same firm.

The core executive team includes Chief Regulatory Officer Rosemarie Fanelli, Chief Financial Officer Jarred Beckerman, Chief Compliance Officer Kenneth Kitchin, Chief Operating Officer Joseph J.
