CityFibre's Chief Executive is setting the company extremely ambitious targets for the next few years.
The company currently has a presence in 35 UK towns and cities, following its £90 million purchase of network assets from Kcom last year.
CEO Greg Mensch now believes this figure could reach 50 by 2020, which means its fibre-to-the-premises deployments would be available to a potential customer base of five million homes.
However, he believes the company could go even further, given what Ofcom said in its recent Strategic Review of the digital communications market.
"With the Ofcom review forcing BT to give us rights to its infrastructure, I can jump from 50 to maybe 100 cities and take the customers I have now and grow the footprint to ensure we have the scale they want,” Mr Mensch told V3.
"I can become a full blown competitor to BT Openreach."
"We are doing exactly what [Ofcom] wants in this industry: we are nimble, innovative and using private capital."
Mr Mensch added that most of the UK population has been misled into believing that BT is rolling out fibre, when it is really deploying fibre-to-the cabinet and then copper to the last mile.
This, he said, means the speeds available to households are "limited".
Fiona Vanier, Senior Broadband Analyst at IDC, is also confident about CityFibre's prospects in light of the recent Kcom deal.
Speaking to V3, she said this purchase has "catapulted" the organisation to the forefront of the broadband market and made it "a real adversary" to Openreach.
