Neil Stevens, managing director of Verbatim, said more than 1700 adviser firms were already using its investment process. The firm also launched a discretionary service last year.
He said: “By partnering with Sandringham, more advisers and clients will benefit from this ethos of a client-centred investment approach.”
Matthew Walne, managing director of Santorini Financial Planning, said: “Sandringham has real financial clout and it’s very heavy on the recruitment process.
“While I’m not a fan of networks, Sandringham is challenging the status quo and I don’t blame it for trying to simplify and streamline the business.”
Sandringham aims to grow its membership to 500 adviser firms in the next two years, increasing to 1000 within four years. Last month the restricted proposition announced it would offer up to 40 per cent equity to advisers and staff.
