where it all began...

Serial entrepreneur and tech obsessive Rob Wellstead had – amongst other things – been a letting agent for over 20 years and, by 2013, he knew he had a problem. The leads from portals such as Rightmove and Zoopla were piling in and many were being called by his teams quickly and efficiently but some weren’t. And he had no way of knowing which fell into which bucket – “dealt with well” or “dealt with not well”. So he created Callwell.

Now bringing his passion for customer service and organisational discipline to other companies and sectors, he saw quickly the benefits that Callwell can provide and co-founded PropTech Solutions in 2016 to relaunch it into the market.
