James Watt has announced that Steven Bartlett will be joining Social Tip as an investor and advisor.
In a LinkedIn post, the former BrewDog chief executive welcomed the SocialChain and Flight Group founder, but gave no further details.
It follows a social post last week, where Watt challenged the line-up of BBC’s Dragons' Den to invest in his new venture, noting that they were being given a second chance, following BrewDog's founders failing to get before the panel in 2009, where they were planning to offer a 20% stake for £100,000.
Social Tip is an app which rewards people for posting about brands.
In his latest message, Watt also gave more details on a pre-seed crowdfunding campaign being launched via Crowdcube later this week.
The fledgling company's strategy document explained that by next year, the plan is to have established itself in the UK and US, with around 100,000 customers and 1,250 business-to-business partners.
Early investors include UK tech fund Haatch (£310,000), alongside the British Investment Bank, MiniClip chief executive Rob Small and early BrewDog investor Keith Greggor. Almost £1.5million has been raised at a £13million pre-money valuation.
