Online agent Doorsteps has reached more than double its crowdfunding target in its latest fundraise, taking the total amount it has now received from the public to more than £1m.

The firm, founded by Akshay Ruparelia when he was still a teenager, was set to receive more than £870,000 from investors as its latest crowdfunding campaign closed yesterday.

It had initially targeted £400,000 with a bold pitch claiming that “the high street is dying”.

The Crowdcube fundraising page shows the campaign was backed by 662 investors, giving up 4.61% of equity and valuing the company at £18m.

The largest investment was for £200,000.

Doorsteps raised more than £500,000 on Crowdcube last year.

It has now raised £1.3m through crowdfunding campaigns, but potential investors in the latest project did raise concerns on the Crowdcube messageboard about the business.

One said: “How do you address the comments left on Doorsteps’ Facebook page about inadequate communication and people struggling to sell/buy their property?”

A response from Doorsteps revealed it has promoted its former property consultant Sarah Carrino, an ex-Yopa and Sequence agent, to head of agency, adding: “Many of these (concerns) are based on small logistical issues or issues that our new portal and technology has now solved, or on its way to solving.

“We have identified many of these and will continue to address any concerns like this, especially as they are in the super minority of our customers.

“Further to this, we have recently promoted internally an estate agency head – with an even stronger focus on customer service and the bandwidth to address any concerns like this.

“This is supported by team leaders and customer resolution teams that are being built/have already been dealing with any process issues – to make the journey frictionless thereafter.”
