Tallia partners with Ostberg Sinclair & Co.
A new partnership, grounded in a shared focus on client relationships.
Built around the practice.
Ostberg Sinclair & Co has partnered with Tallia following a competitive pilot. Its advisers worked with the Tallia team to configure and test the platform ahead of deployment.
The firm specialises in UK and US tax, serving businesses, private clients, and entrepreneurs with interests across borders. Its relationship-led practice operates across London and New York.
Founding partner Linus Ostberg highlighted research across trusted sources in multiple jurisdictions, alongside a design that supports human review, as reasons for choosing Tallia.
The partnership reflects the firm’s approach to technology: using it to support its advisers and give them more room to focus on clients.
“As cross-border specialists, one of the key features of Tallia is the ability to research trusted sources across multiple jurisdictions with each query. This, alongside a design that promotes human review, enables us to deliver certainty to our clients both in the UK and US. Technology is at the core of our business and enables us to focus more on relationships with our clients and how we can best serve them.”
