By addressing network issues and potential security risks in a proactive way before they became problems, they found that they could prevent the kinds of issues that can cause huge frustrations day to day but also can be damaging to businesses.

Having acquired many hospitality clients over the years, mainly by recommendation from one venue to another, they began to develop a deep understanding of the types of issues and frustrations the hospitality sector face.  IT support for hospitality has become a specialism of Astaris and they now focus entirely on the hospitality industry providing IT support to restaurants, bars, pubs, hotels, music venues and nightclubs.

Having recognised it was these type of businesses who were most profoundly affected by network problems, as losing connectivity during peak operating times would often result in huge losses, Astaris gradually developed a specialism.   Their proactive approach is ideal in making the chances of such outages at busy times as low as possible but also support provided ‘out of hours’ when venues need rapid response, also means that they have been able to get them out of trouble very quickly to minimise lost revenue.

That’s what makes Astaris the go-to IT support company for hospitality businesses.

Mark joins us as business development manager having been working in the hospitality industry for over 20 years.  He managed hotels, bars and restuarants and therefore has first hand experience in the issues that hospitality venues face with their IT and infrastructure.  He knows only to well that there is never any issues at 10am on a Tuesday morning, if anything is going to fail it will be at 10pm on a Friday night when there is 10 deep at the bar.  Because of his experience he makes IT recommendations that he knows will enhance businesses because he has been there, seen it, done it.  Mark says "I do understand the issues venues face, so it gives me great pleasure to now be in a position to be able make life easier for people that could have been my colleagues!

The decision for Ivan and Sacha to work together to run Astaris, was based on the fact that their skills  were so well suited to cover all the important areas of running an IT business.  With 25 years’ experience of working in IT, Ivan had all the technical knowledge and experience while Sacha had a wealth of experience of marketing and management so could manage the business side of things.

Since starting Astaris, the business has gone from strength to strength and due to the expansion of the team, recently made the move to much larger premises at Shoreham Airport.  The team is comprised of long standing employees who, having been nurtured from young trainee apprentices, are now experienced IT engineers with other young people following in their footsteps.

The whole team, including the management, admin staff, accounts staff and engineers, work together in a fun and supportive environment with the same working ethic which is to protect their hospitality clients from IT network problems that damage their business.

I’ve known Ivan for years so I knew I could rely on him and his team to do a great job on installing a complete network solution at my venue, but also providing prompt support at the times we needed it.
