Trading, risk and reporting software for funds.

What we do

assylias builds trading, portfolio-management, risk and reporting software for asset managers, hedge funds and family offices — the systems that require a deep understanding of the business and the data. We build them with AI, and we keep the AI on a leash.

Where we come from

assylias was founded in 2013 by Yann Le Tallec, then Head of Risk at Ecofin in London (2006–2014). There he had risk oversight of up to $6bn across long-only and long/short funds and built the firm’s risk, trading and portfolio-monitoring platform because nothing off the shelf fitted. assylias exists to do the same for other funds.

What we have built

We work for the buy-side. What we have built includes: a security master; a pre- and post-trade compliance tool; automated position reconciliation; an order management system with FIX execution. We also contribute to open source, and our jBloomberg library, built on the Bloomberg API, is used at several hedge funds. The case studies show the detail.

How we work

What we build is shaped around your data, integrated with the systems you already run, and left in a state your team can maintain — or that we maintain for you. We are meticulous about architecture and about tests. Our AI pipeline is how we get speed without giving up correctness.
