The 23-year-old was man of the match after taking six wickets in the final test at The Oval, to beat Australia 2-1 in the series.
‘In PR terms, Broad ticks a lot of boxes, young, an all-rounder and an intelligent, articulate, good-looking lad,' said Threepipe co-founder Eddie May.
‘There will be plenty of brands interested in being associated with him on the back of the Ashes win. If he gets it right, this could take his earnings well into six figures.'
Broad is being touted as the next Andrew ‘Freddie' Flintoff, but the young all-rounder will be keen to avoid some of Flintoff's PR gaffes, which include missing the team bus to visit war graves in Belgium this year and the infamous ‘Fredalo' incident of 2007.
‘Part of Freddie's wider fame and appeal was down to his off-field antics. However, Broad will not want to replicate these and so he will need to develop a PR strategy for maintaining his profile outside of the sports pages in a way that suits his personality,' said May.
Ocado, the online supermarket, was ahead of the game signing up Broad before his Ashes heroics. Ben Lovett, PR manager for Ocado said: ‘We have been working with Stuart throughout the series and are thrilled he proved pivotal in bringing home the Ashes.'
‘He is a great ambassador, and his ‘Broad' brand appeal will only get stronger following those amazing fifth Test heroics,' added Lovett.
The reputation of the England and Wales Cricket Board and the sport in general could also receive a boost after coming under fire for its links with the disgraced Allen Stanford earlier this year.
The Ashes has seen a number of celebrity fans Twittering and commenting on the sport, such as Daniel Radcliffe and Lily Allen, potentially widening its appeal.
Simon Crellin, MD of Redpoint PR said: ‘The growth of websites reporting ball-by-ball action and social sites such as Twitter are creating different ways of following the action. The majority of followers Lily Allen has on Twitter are not traditional cricket fans, but they have been exposed to her opinion on the series.'
