Lis Howell, senior vice-president of Flextech Channels, has resigned from the company to form her own start-up venture.
Flextech will be taking an equity stake in the new venture, which is expected to combine TV and internet content.
Further details will be announced in the new year.
Howell’s departure follows the appointment of Jane Lightning as chief operating officer of TV and content earlier this month.
Lightning joined the company as part of Flextech’s £4 million takeover of Minotaur, the TV distribution company she founded.
Howell is understood to have been considering starting her own company for a while.
In a prepared statement she said: “This is a fantastic opportunity. I’m grateful to Flextech for its support. It’s been an amazing six years, seeing Living established, followed by Trouble and Challenge.
“But I’ve been nursing this idea for some time and I’m really pleased Flextech wants to be involved.”
Separately, it has emerged this week that Flextech has heldinternal discussions with a view to making an offer for a share in beeb.com, the BBC’s commercial web property.
Media Week has learnt that Flextech has mooted the idea of bringing beeb.com under its control in a similar arrangement to its UK TV deal – where Flextech and the BBC each have a 50% stake in the five channels.
It is believed that Flextech Interactive, the company’s new media arm, would use the beeb.com portal, which includes content from Top of The Pops, Top Gear and Radio Times magazines, to provide interactive elements for UK TV channels.
