Investors associated with the Halo Angel Business Network (Hban) put a combined €16.8 million into 66 Irish start-ups last year.
This is a dramatic increase on the €9.3million invested in 44 companies in 2018.
The figures come as 246 angel investors shared a major payday last week with the €363 million sale of Irish chip-maker Decawave to US Apple supplier Qorvo.
Established in 2007, Hban is a joint initiative of Enterprise Ireland and InterTrade Ireland that serves as a go-between to bring start-ups and investors together.
New figures from the organisation show that companies who received investment from business angels were able to leverage a further €36 million from other sources to bring total funding to €52.8 million.
The average angel investment deal last year was €255,000, some 18 per cent higher than the 2018 figure of €215,000.
The ICT sector accounted for the most deals with 25 investments. It was followed by the medtech sector, which saw 10 deals.
Among the start-ups to receive investment via Hban last year were CroiValve, AventaMed, Bluedrop Medical, Buymie, Hexafly and Deciphex.
Hban investors have ploughed more than €100 million into Irish start-ups since 2007.
