The Apprentice runner-up Ruth Badger is to appear on a TV show aimed at finding inventors and entrepreneurs.
Badger lost in an all-female final of the BBC's The Apprentice
Ms Badger will act as an adviser on Sky One's The Big Idea, which offers a £100,000 prize to help fund a budding business venture.
The channel's autumn schedule also features The Race, in which celebrities including Cerys Matthews and Goldie will compete on a Grand Prix circuit.
Disgraced former football pundit Ron Atkinson returns in Big Ron Manager.
The programme will follow Atkinson, who was forced to quit his job as an ITV commentator over a racist remark, as he tries to guide Peterborough United to promotion.
The Big Idea will conduct a nationwide search for invention and business ideas, with would-be entrepreneurs competing for £100,000 to invest in their project.
Ms Badger is due to mentor contestants on the show, as well as having a major role in a spin-off programme on Sky Three.
The Wolverhampton sales manager reached the final round of the second series of BBC Two's The Apprentice earlier this year.
She admitted she was "gutted" to be beaten by Michelle Dewberry to a £100,000-a-year job working for Amstrad boss Sir Alan Sugar.
The first all-female final followed the elimination of 12 other contestants.
Blood, sweat and tears
Formula One stars David Coulthard and Eddie Irvine will captain the teams in The Race, hosted by Denise Van Outen.
In a series of races, 10 celebrities will drive vehicles including rally cars, off-road buggies and monster trucks.
The climax will be a race at Silverstone Grand Prix circuit.
Sky One programme director Richard Woolfe said: "Our round-the-clock cameras will capture all the blood, sweat and tears in this ultimate test of speed and ability.
"The celebs may have Porsches and Lamborghinis, but it doesn't mean they can hack it on a professional Grand Prix circuit."
The channel's autumn season will also include Cirque de Celebrite, in which celebrities train as circus performers.
A Robbie Williams performance from Roundhay Park in Leeds will be the first live concert screened in high definition.
Sir David Jason will star in the Terry Pratchett adaptation Hogfather.
