This case study explores Signly’s R&D claim process with Leyton.
About the client
Signly is a world-first, innovative accessibility technology company focused on adding sign language to websites to make digital content inclusive for deaf users.
Recognising that screen readers have long supported blind and low-vision users, there was no equivalent solution for people who use sign language as their primary means of communication, Signly set out to bridge this gap. Their technology enables websites to deliver information in sign language, improving accessibility and usability for organisations while creating a more inclusive digital experience.
With a strong focus on product development and user impact, Signly continues to innovate in the accessibility space, helping businesses better serve deaf communities and meet evolving accessibility standards.

About the claim
“We’d done a number of R&D claims before, so we had a good benchmark, but this experience was remarkably different.
With some of the R&D firms we had worked with in the past, it felt like a DIY job that they then checked over. This was a completely different level of support.”
Mark Applin | CEO, Signly
The process
“How did we find the claim process with Leyton? It was absolutely outstanding.”
It was smooth and proactive, the team were really happy to do the groundwork, and we were just checking things and filling in gaps, it was remarkably different to our previous claims and we have done a number.
There were regular, structured meetings. We’d hand over what was asked for and that was it, it all felt really well organised and easy to manage.
“This meant submitting the claim was really straightforward, which was a big benefit for me.”
The benefit of the claim
“We view the money from the claim as another pair of hands, so we can develop more product for our service users.
What really stood out was the added value, Leyton spotted legacy errors in our accounting and helped us remedy them, which gave us real peace of mind.
That extra support made us feel like we were in really safe hands.
“As a business focused on accessibility, the claim allows us to keep innovating, delivering more for our users and directly supports our ability to continue developing our product.”
What would you say to other businesses thinking of claiming?
“The process felt like a proper partnership rather than just a transactional relationship once a year.
We’ve worked with a number of providers who have all been adequate, but Leyton were excellent, so give them a go.”
