When Katie Anderson set up an Instagram page for her vintage clothes business, she never dreamed it would be anything more than a side hustle.
That is, a rewarding fun small part-time project which earned her a little cash on the side from her main job.
Fast forward three years and she has generated enough profit to go full-time and match her previous salary in her job as a marketing director.
Like a growing number of entrepreneurial Britons, Katie's first experience of running her own business came as a side project while working full-time.
The challenges of the pandemic, combined with the cost-of-living crisis, means more and more people have set up their own companies to supplement their income.
Many of those who have taken the plunge are reaping the benefits. Recent research by website hosting platform GoDaddy shows the average UK side hustle generates £22,900 a year in supplemental income.
A fifth of side hustlers are making more than £25,000 a year, while 11 per cent are earning over £50,000. Meanwhile, 4 per cent are making six figures or more.
Katie set up the Pine & Treasure page in 2019 while travelling with her husband in New Zealand for a year.
Her aim was to make a bit of extra cash selling secondhand clothes and she had no plans to continue it once she was back in the UK.
She says: 'When I left New Zealand in December 2019 to return home to the UK I thought I'd be leaving it there and switching off the account. I felt gutted to be leaving it, but my entire customer was NZ based.
'My husband encouraged me to just give it a go when I returned home and thank God I did.
'It just goes to show how you can develop an online business and pivot along with whatever circumstances you're going through.
'I would have never, ever imagined when I set up the Instagram page. that I'd be doing it now as a full-time job.'
The ease and speed of setting up a side hustle online, whether through social media like Katie, or via a website, means 70 per cent of entrepreneurs hope to turn their side hustle into their primary business, GoDaddy research shows.
After running Pine & Treasure for three years alongside employment, Kate handed in her notice at the end of her maternity leave last August.
'By that point I'd already trialled how viable it would be to purely live off my Pine & Treasure income. I used my maternity leave as a mini test to see if it would work, and it did.
'It didn't seem risky as I'd really dragged it out as a side hustle. I felt fully comfortable to take it full time by that point. I'd built a strong and reliable customer base and reputation.'
Since then, the business has stepped up a gear. She launched her website in April 2023, which cost £230, to start selling her made-to-order pieces.
Pine & Treasure now generates enough profit for Katie to manage it full-time, matching her previous salary as a marketing director for a creative agency.
The future looks as bright for the UK's other online side hustlers too. Almost two thirds of the 521 entrepreneurs surveyed by GoDaddy expect their venture to grow by the end of the year. Just three per cent thinks they will decline.
Andrew Gradon, head of GoDaddy UK & Ireland, said: 'It has never been easier, or quicker to set up an online side hustle, and GoDaddy's data shows the financial rewards can be significant.
'Technology has dramatically reduced the barriers to entry, giving entrepreneurs the tools to start and grow their businesses in no time at all.'
