Welcome to The Fintech Files, keeping you up-to-date with the latest developments in financial tech and innovation. Regular host Yolanda Bobeldijk is on maternity leave, so this week's edition is brought to you by David Ricketts, FN's asset management correspondent.

The robo-adviser of robo-advisers
The story of robo-advisers is an old one, or so thinks Lex Deak, serial entrepreneur and creator of a new breed of online wealth management tool. Deak, who was the brains behind the launch of peer-to-peer lending aggregator Off3r, is rolling out a new online service that he claims will bring web-based investment to the masses and “battle the bias and bullshit that has dogged the investment sector for decades”. The new service, called Personal Investment Assistant — or Your Pia — uses artificial intelligence to help investors sift through a range of robo-advisers, wealth management platforms and IFA networks.
