About
Nineteen yearsof the work.
A technical studio for search, software and AI systems. Based in Hersham, Surrey, working with companies in the UK and the US.
Sequentis is a small technical studio. We look after the part of a business that lives online, from how it is found to how it keeps running. The people who plan the work also write the code and read the numbers afterwards.
How we work
Measured at the source
We read the crawl, the server and your own analytics before we change anything, and read them again after.
Planned and built by the same people
The people who plan the work write the code. Nothing is lost in a handover because there isn't one.
Everything is yours
The code, the content, the domains and the accounts belong to you from the first day.
Every number has a source
Reports say where each number came from and when it was read, so nothing has to be taken on trust.
The founder
Sequentis was founded by Jamie McKaye, who has spent nineteen years building and growing sites for companies of every size, from local practices to global brands.
His own sites have been recognised by Awwwards twice: jamiemckaye.com as a nominee, and The Shape of Intelligence with an honourable mention, both in 2026.
