Deal-doers at Clearwater Corporate Finance - which claims to be the UK's fastestgrowing boutique - have created 85 millionaires in just three years.
That is the result of 61 deals worth £900m.
Clearwater is hailing a record financial year to March, when 24 deals were completed with a value approaching £0.5 billion.
With ten partners and 30 staff, Clearwater focuses exclusively on mid-market transactions with a value of up to £100 million, delivered by teams in London, Birmingham, Manchester and Nottingham.
Keynote deals in the year were the £82 million manage-ment buyout of Interfloor, Europe's leading flooring accessories business, and acting for Indian listed automotive business Amtek, on its acquisition of German based Zelter.
In addition, Clearwater advised on the £62 million MBO of Ashworth Mairs, a leading loss adjuster and the £51 million MBO of shoe retailing group Stead and Simpson.
The firm's "league table of wealth" was dominated by the support and financial services sectors, which accounted for 33 millionaire-making-deals, with eight each from transactions relating to healthcare and home and building products.
Other sectors in which Clearwater deals produced millionaires included print and packaging (seven), construction, engineering and retail (six each), technology and media (five), consumer products (three), food (two) and waste services (one).
Clearwater's deal value increased year on year, culminating in an average transaction value of £18.7 million last year.
Joint-managing director Phil Burns said: "Our league table of wealth creation is more than a fanciful exercise, it heavily underscores our philosophy of harnessing our own direct experience of the entrepreneurial corporate finance sector to generate extra shareholder value for our clients' transactions.
"We were born out of an MBO, giving us first hand insight into the sharp end of the corporate finance marketplace. As a result, we have put a great deal of resources into evolving a highly skilled research team that illuminates the dynamics of niche markets, enabling us to deliver the results clients want."
Cumulative internal rate of return for private equity investors over the past three years was 58 per cent, while the average cash multiple for management team investors was more than 14-fold.
Meanwhile, the UK buyout market achieved a record performance during the second quarter, with the value of deals breaking the £10 billion mark for the first time, a study showed.
The number of transactions concluded between April and June increased to 46 with a total value of £10.08 billion, according to KPMG's Private Equity Group, which tracks UK buyouts with values of more than £10 million.
That compares with 44 deals being agreed in the same quarter last year, totalling £8.34 billion. The two biggest deals during the period were the £2.2 billion purchase of General Healthcare Group by Apax and Brockton Capital and the £1.8 billion sale of Select Service Partners by Compass Group.
