The six-strong pubco, which was co-founded by British Institute of Innkeeping chairman Anthony Pender, said it was looking for "London's kindest, kookiest and cleverest person" to launch its new random acts of kindness project.
"Ever heard of the guy who put $5 bills in library books, the café that opened its doors to stray dogs on cold winter nights or the man who gave away money to 35 people on his 35th birthday, instead of asking for presents of his own? We have and we love it.
"It's about giving something to others for nothing in return but, really, it's not just a selfless act because it makes you feel good about yourself, too. We're going to shower the country with random acts of kindness, big and small, as soon as we find the right person to lead the campaign and join our family," said Pender.
On Twitter, Yummy Pubco director Tim Foster said the company had already received some "incredible" applications for the role.
The company kicked off its random acts of kindness project in February to celebrate the launch of its latest site, the Stoke Newington Tea House by customers the chance to reward those they saw being kind with a free drink.
