Mr Oliver passed away before Christmas last month, after a “short but bravely fought” battle with cancer.
“On behalf of our board, the management team and all employees, we extend our heartfelt condolences and sympathy to Joel’s family and our thoughts are with them at this most difficult of times,” the board of directors said in a statement.
“Joel was a dynamic individual whose remarkable passion and energy was evident to everyone he met,” the board said.
“Joel was known and respected for championing and pioneering the development of apps in [the accounting and bookkeeping] sector and we would like to pay tribute to his lasting contribution,” the board said.
Current chairperson Gavin Disney-May will take over as interim CEO effective immediately.
David Oliver, who is Joel’s father and currently part of the executive management team, has been appointed to the board.
“They are committed to carrying on Joel’s legacy and fulfilling his wish to see Apps transform the digital landscape and ease the client communication challenge faced by accounting firms the world over,” the board said.
Chief executive of not-for-profit organisation B1G1 Paul Dunn said Mr Oliver struck him as a “man on a mission.”
“He leaves a great and powerful legacy — so many accountants and their clients around the world are now doing things they never imagined thanks to Joel,” Mr Dunn said.
Mr Oliver founded MyFirmsApp in 2013, after a 20-year career history in sales, training and marketing.
Vale, Mr Oliver.
