Light Frame Raises $5.1 million Seed to Bring AI Core Banking to Private Wealth

Light Frame raised $5.1 million in a seed round led by Fortino Ventures, with Sidekick Partners, Tenity, Chameleon and Altair Capital also participating, Tech Funding News reported on November 10, 2026. Existing investors Rogue Venture Partners, New Stack Ventures and Studio Alpha were also on board. The round was oversubscribed and brings total disclosed funding to $6.8 million, including a $1.7 million pre-seed round raised in May 2024.

Light Frame's Seed Round and Alpian Roots

CEO Schuyler Weiss started Light Frame in January 2024 with Mathieu Clément, former COO and CIO of Alpian, Philippe Kernevez and Gregory Bataille. Weiss had set up Swiss digital bank Alpian on a legacy core banking system because no modern alternative existed for wealth at the time. "It was expensive, slow to change or implement, and we got about half of what we asked for," Weiss told Tech Funding News.

Weiss stepped down as Alpian's CEO in September 2023, with the bank saying he was leaving to pursue public service in the US. He said he had grown Alpian from "just myself" to about 150 people, and that Intesa Sanpaolo eventually took it over. In May 2024, Alpian announced a CHF76m Series C round, with Fideuram becoming the majority shareholder.

Light Frame says its platform is cloud-native, API driven and AI-enabled, and modular so banks can plug in the parts they want or take the whole suite. Weiss said most old systems work in a batch fashion at the end of the day, so data is a day old, while Light Frame's system is entirely real time. On corporate actions, he said the system reads a plain-text SWIFT message and suggests the appropriate booking, with a person validating the output. "AI is fundamentally probabilistic, so there's a probability attached to its output," Weiss said.

Hugh Phelan, investment manager at Fortino Ventures, said, "Schuyler and the team have run a regulated Swiss bank on the kind of infrastructure they are now replacing." Weiss said the company originally had a target of $5 million and ended at $5.1 million after scaling back a bit. Light Frame will hire in sales and go-to-market roles and invest more in security, resilience and capability, with a focus on Europe, the Middle East and Africa. The core team has over 10 people, with about 20 in the wider team.
