Alan Sugar has chosen Dean Franklin as the winner of The Apprentice 2025, saying that he has been "quite good".
Sugar will now go into business with Franklin and invest £250,000 in his air conditioning business.
Anisa Khan, the owner of an Indian-Italian fusion pizza company, was the beaten finalist in Thursday's episode of the BBC One business show.
Franklin said: "I can't believe I've just won The Apprentice. This is going to mean the world to me and my family. My kids are going to be over the moon."
In the final, Sugar met Khan and Franklin at The Honourable Society of Lincoln's Inn, in central London, where he gave them the final challenge of launching businesses.
Sugar told them they would need to create a new brand for their companies, and produce an advertising campaign, which would then be pitched to him and a group of industry figures.
He then brought back some of the show's previous contestants - including Dubliner Jordan Dargan - and allowed the finalists to choose who they wanted on their team.

Sugar told Khan that pizza was a "crowded market" and food businesses "go bust every day", so she would need to prove that her business could "stand out in the face of tough competition".
Franklin was told that air conditioning made him an "honest living", but he needed to show a "scalable proposition".
Franklin's advertisement featured fired candidates Mia Collins and Nadia Suliaman in a comedy skit, in which Collins freezes in her bed before being told about Franklin's air conditioning services by Suliaman.
Sugar's adviser, Karren Brady, said the advert made "no sense at all" and that it focused on the "secondary use" of an air conditioning unit.
Franklin called the team and told them it needed to focus more on customers who are too hot.
The clip was then changed to show Collins flustered and hot before being visited by Suliaman.
Khan's advert was shot at a football ground. Fired candidate Amber-Rose Badrudin directed her former candidate actors to pretend to be fans of India and Italy enjoying the finalist's pizza, fusing pizza with Indian cuisine, at a match.
Later, the contestants pitched their businesses. Khan told the group to try her pizza and Sugar, after taking a bite, was asked if he thought it was nice.
He replied: "Oh blimey, yes. This is very good."
Khan then told the audience her Zaal Pizza business "fixes a problem", and it allowed people to have both a curry and a pizza if they could not decide which takeaway they wanted.
After the pitch, Sugar said he was concerned about how Khan would attract people to her 'dark kitchen' business model, in which food is delivered from a kitchen with no shopfront.
Thom Elliot, of the fast-food chain Pizza Pilgrims, who watched the pitch, told Sugar that dark kitchens are a "hard place to build a brand", but Khan's "really unique" offering was a "massive, massive plus in a crowded market".
Franklin entered his pitch to Daddy Cool by Boney M, prompting a slight grin from Sugar. Franklin then told the audience: "I am Daddy Cool."
He said he wanted homeowners to know how "quick and easy" it is for them to get an air conditioning unit installed by his Domesticool company, saying he understood customers wanted it "there and then".
Sugar exclaimed, "Oh God!" as he watched Franklin's advert. Franklin then presented the group with his virtual showroom, including a function that allowed customers to use virtual reality (VR) to see what a unit would look like on their wall.
In a question-and-answer session during the pitch, Sugar asked how much it would cost to have a unit put in his bedroom. Franklin replied: "For you Lord Sugar, it would be free."
Sugar replied: "Well, then you won't be hired by me if you're giving things away!"
In the boardroom, Sugar praised both finalists for a "spectacular evening", adding that Franklin's advert had "started to sound and look like a dodgy adult film".
Asked by Sugar about her thoughts on Khan, former contestant Chisola Chitambala said: "I have been with Anisa from the beginning, from day one we've worked together a lot.
"And honestly, she has just stood out, every single week. She's been incredible."
Sugar described the final as "chilli versus the chiller", before telling the finalists he was looking for "big business".
Before he announced Franklin as the winner, Sugar said they were both "very, very incredible" and the decision was "tough".
Brady said: "I like Dean. I think the issue for him is he doesn't know how to scale up. This is where he needs you. He's lacking that bit of confidence on if the decisions he's making are the right decisions. And I think you'll give him that push that you need.
"I think the difference between the two candidates is this - Dean's got a business. You're investing in that business and helping him scale up. Anisa, yes, she has a business. It's tiny, but you're really investing in her."
The two contestants made their final impassioned pitch to Sugar before he made his final decision.
Sugar said: "This is the way I see it.
"Dean, through the process you've been quite good. There have been a few rocky moments where you remained in it by the skin of your teeth, but do I have the confidence in the residential market?
"As opposed to food, where everyone's got to eat, and a £10, £12 pizza is affordable to most people.
"That's where I am at the moment.
"Giving it deep consideration, I'm going to say that, Dean, you're going to be my business partner."
