Studio Graphene and City Road Communications have partnered up to reveal how the reality of starting a business compares to its reality.

Based on a survey of more than 100 founders of London-based tech businesses, the study found for over half (52 per cent) of start-up founders it took much longer than they thought to launch their business.

15 per cent also said it was “far more expensive” than they predicted and almost a quarter (22 per cent) found the experience more emotionally draining than they believed it would be, with a further 20 per cent saying they felt isolated when starting their new business

In total, one in six (15 per cent) start-up creators found it more difficult to adjust to the life of running an early stage business than initially expected.

The survey found acquiring customers once their product launched was the biggest obstacle cited by start-up founders with 33 per cent of respondents saying this was a problem.

Moreover, 22 per cent of entrepreneurs struggled to obtain funding to develop an initial proof of concept.

Access to talent was also a common issue with 15 per cent saying they struggled to find support to build the technology itself. 12 per cent could not hire the employees they required to really get their business up-and-running.

The research provides insight into a huge, expanding market. London’s tech start-ups receive a significant amount of attention, not just within the UK but also from a global audience.

Dubbed Europe’s ‘digital capital’, there are now 187,427 tech companies in London that employ 1.19 million people and have a combined turnover of £285 billion.

The exponential growth of London’s tech sector has largely been driven by an influx of new start-ups – it is reported that a new tech business is formed every hour in the capital.

However, despite all the praise the sector receives, little focus is placed on the challenges and pains experienced by the entrepreneurs behind these new businesses.

“It’s amazing to see how much entrepreneurial talent there is in London, particularly in the tech space,” said Studio Graphene founder and director Ritam Gandhi.

“But despite all the great ideas budding entrepreneurs have, the research shows just how difficult it is to convert an idea into a successful business.

“From our experience, it’s vital tech start-ups remain focused on their core proposition and ensure the product functions as well as possible – thereafter they can adapt and evolve based on customer feedback, which will set them up for more long-term growth.”

Dominic Pollard, director of City Road Communications, added: “London has long been a global hub for exciting, innovative new businesses.

“Amidst such competition in the tech sector, it’s not surprising that the biggest challenge start-ups face is to acquire customers after launch.

“Evidently, as well as building an amazing product, tech entrepreneurs in the capital must have an effective strategy to secure positive exposure for their brand in front of the right audience – the need to stand out is greater than ever.”
