The move will see Broadlake take a 30pc stake in TTM, which recruits specialist healthcare professionals in both Ireland and the UK.
It is understood that the majority of roles will be based in the firm’s headquarters in Ennis.
TTM currently employs 1,200 people and has a turnover of in excess of €50m. Half of the company’s revenue comes from outside of Ireland.
The healthcare firm is looking to triple its revenues and double its workforce over the next five years.
Speaking about the investment TTM Group chief executive Brian Crowley said: “TTM has grown rapidly in recent years and this investment will help the company to reach new heights in terms of both expanding the team and our service offering to clients. We can see huge opportunities for our business to scale over the next 5 years.”
Meanwhile CEO of Broadlake, Pete Smyth, said: “What attracted us to TTM is the quality and ambition of the team, the innovation of the healthcare services they offer and the high standards of care that TTM provides for its patients and customers.”
