Dundee and Angus Chamber of Commerce held a business lunch event as part of Angus Business Week yesterday.
Attendees heard the story of Brewgooder, a beer company which gives all its profits to providing clean water in other countries.
Company founder Alan Mahon has set the ambitious target of providing a million people with clean water.
The company’s beer is brewed by Brewdog at zero margin and is now sold in supermarkets and more than 30 bars.
Mr Mahon said it had allowed several projects to get under way in Malawi.
He is also a trustee of the Social Bite project which provides job opportunities for homeless people in Edinburgh, Glasgow and Aberdeen.
Also speaking at the event at Carnoustie Golf Hotel was Paul Barrett, who runs the Arbroath-based health and safety business IED Training Solutions.
He spoke of how he was inspired to set up the company after he lost a leg and part of his hand after stepping on an improvised explosive device while serving in Afghanistan.
The event, which was attended by around 130 people, also heard from Angus Council chief executive Margo Williamson, who spoke about the importance of supporting a young workforce.
Ms Williamson said she was delighted that Angus Business Week was growing in popularity each year.
She added: “This is the fourth year that’s been running and there’s a packed programme of events.”
The events continue today with a showcase at Angus 3D Solutions in Brechin.
Tomorrow a business breakfast will hear about the Montrose South regeneration project.
