Who founded Synthax?

In the funding announcement, Dr. Shaheer Aslam Joiya, CEO and Co-Founder of Synthax explained:
As a clinician, I've seen how much of our time is swallowed by paperwork and antiquated systems. Synthax is our answer to that – to equip outpatient clinics with the same AI advantages larger institutions enjoy.

In the funding announcement, Mark Murtagh, CTO and Co-Founder of Synthax said:
From global tech to high potential healthtech, I’ve seen the difference good engineering makes. In healthcare, small clinics have been left behind.
