James, who founded the online fundraising platform in 2016, was officially appointed to the board yesterday, according to the regulator’s entry on Companies House.
He will become an active board member on 18 July, when the board next meets, and will serve for three years, the regulator said in a statement.
"The appointment represents the regulator’s commitment to broadening the range of experience on its board and to drawing on varied fundraising expertise," the statement said.
The move comes a week after the regulator announced changes to the Code of Fundraising Practice that extended the document to cover online fundraising platforms such as Wonderful.
James is also managing director of the Call Collective, which runs WHYPAY?, a free telephone conferencing service.
Lord Grade, the regulator’s chair, said: "James’s experience and expertise will prove invaluable to the Fundraising Regulator as we aim to keep abreast of digital fundraising developments.
"We are committed to ethical fundraising that protects the donor, whether it takes place in person, by telephone or online."
In April the regulator announced it had appointed the accountant Jill Thompson to the board to replace Lucy Caldicott, chief executive of the youth organisation UpRising, and had renewed the terms of two other board members, Jenny Williams and Sacha Deshmukh.
