Mark Dougill


Managing Director

Mark has spent his whole career working across the UK rail industry and has held several senior positions within a number of large engineering and technology companies including Network Rail.

Using his industry experience and knowledge, Mark founded Gryphon in 2008 with the intention of providing specialised advisory and project support to large transport and technology organisations.

Some 15 years later, Gryphon has gone on to achieve great success working alongside many of the UK’s leading transport and technology businesses delivering a broad range of engineering, technical and commercial programmes.

Highlights over that past 15 years include

  • Engaged to provide a range of specialist engineering, project delivery and commercial support across the UK involving over 800 stations and operational buildings
  • Provided specialised support to a range of successful rail franchise bids that focused on station development and the deployment of new technologies and systems
  • Provided strategic business development consultancy to our technology clients that have resulted in additional revenue generation in excess of £200m
  • Securing a network of partners that enable us to scale and provide a broader range of specialist engineering and delivery services to our clients
  • Strengthening the team with additional subject matter experts covering operational property, signalling and other light-rail / metro derived systems

“I feel very privileged and grateful to have worked within this unique industry for so long and to have met so many passionate and capable people along the way. For someone whose services more often revolve around technology deployment, it gives me the greatest satisfaction when we are able to take an idea, present it to a boardroom and then have the opportunity to physically deliver that idea through to completion”.
