Paul Marriage and John Warren, former managers of British fund manager Schroders, have launched their own boutique firm named Tellworth Investments in collaboration with investment firm BennBridge.

The new firm will manage £385m in client assets. The assets are held within the Schroders UK Dynamic Absolute Return fund that was moved following the departure of Marriage and Warren from Schroders earlier this year.

Tellworth has recruited Stephen Nash, another former Schroders executive, as trading head.

Nash will be supported by Seb Jory who will join Tellworth as head of data driven strategies and James Gerlis who will join as an equity analyst. Jory earlier served at Liberum Capital, while Gerlis served at BlackRock.

“We have worked with Stephen since the outset in 2005. We are confident his experience and expertise will continue to bring great benefits to the team. Meanwhile, Seb and James will add an additional dimension to our investment process giving us potential to launch further funds in the future and widen our product offering through BennBridge,” Warren noted.

BennBridge COO Greg Thomas said: “We are excited to launch our first boutique with managers of such high calibre. Our strategic long-term partnerships are key to our business and we are confident Paul, John and the team will build on their success at Schroders and continue to grow.”
