Leeds-based Firstnet Data Centres has received a "multi-million pound" investment from new chairman Jason Beresford.
The firm was formed last year, after Firstnet merged with Select Data Centres.
The merger created two divisions - with reseller arm Firstnet Solutions going out of business earlier this year.
Beresford said: "Having met with Stephen and the team I was impressed by the services and facilities on offer.
"The strategy and direction for the company is compelling and I decided to use them to provide the critical IT infrastructure and services for an investment management business I lead.
"I believe there will always be a role for local service providers and facilities. The cloud and IT services should not always have to be a faceless entity...
"There is a question of scale and further growth; I'm confident that Firstnet are already ahead of the curve and will succeed."
Firstnet did not reveal the amount invested by Beresford. A filing with Companies House lists him as a shareholder with a greater stake than 25 per cent, but less than 50 per cent.
Leahy said: "We are delighted to announce our new chairman and investor.
"With Jason on board this represents a significant step in our strategy of building the largest datacentre service provider in the northern digital market.
"We are excited to have commenced this journey and look forward to making some bold acquisitions in the very near future."
Joe Macri says the vendor saw 20 per cent of its UK growth come from its Cloud Solution Provider programme last year
