Legalesign, which started trading in 2013, said its eWitness service is the first of its kind in the UK, enabling documents that need a witness to be completed online rather than with paper and ink.
The firm currently handles more than 1,500 contracts a day, serving clients across Europe, North America and the UK from its offices in Edinburgh and London. It said that more than a quarter of contracts are signed within five minutes, with more than a half completed within 24 hours.
Chief executive Ben Eliott, said: “The lengthy and arduous process of collecting signatures is consigned to the history books.
“E-signature technology is exactly the development businesses can use to gain a competitive advantage while slashing their costs. eWitness is an exciting development for the digital economy and for what it can bring to business.”
