The Ardoch centre at Gartocharn, Dunbartonshire said it benefited from a big increase on spending on events such as conferences, team building courses and away-days for staff by companies in the six months to June, compared with the same period last year.
Founder Peter Armitage reckoned the increase in business reflected growing awareness of the centre and a revival in corporate confidence this year.
He said: "The first half of 2012, when the UK was in recession, was excruciatingly slow for us but business started to pick up towards the back end of the year.
"Since January we have been operating at much higher capacity, mirroring changes in official figures showing the economy emerging from recession and more money circulating around the system."
Ardoch said nearly all its new business had come from Scottish companies. It recorded a big increase in bookings from firms in the financial services, whisky and manufacturing industries.
The 17-bedroom venue has had inquiries about potential bookings connected with the Commonwealth Games and the Ryder Cup golf tournament, which will be held in Scotland next year.
Ardoch anticipates revenues in excess of £250,000 in 2012 and more than £300,000 in 2014.
Mr Armitage developed Ardoch on farm land near Loch Lomond using capital he accumulated during a successful career in fund management.
He has said he invested "several million pounds " buying the Ardoch estate, refurbishing the existing buildings, erecting a new one and upgrading the land.
The Yorkshireman intended the centre would use the money generated from corporate business to finance its use as a resource for a number of charities.
Ownership of the estate transferred to the not-for-profit Ardoch Foundation in 2010.
