The Simulator Company builds the world's most advanced ECMO, ECLS and LVAD simulators: responsive, AI-driven systems where the simulated patient reacts to every clinical decision.
Founded by Sagar Haval, recognised as the world's first clinical perfusionist and ECMO expert to bring his own independent innovations to the global market, and co-founded with Babita Haval as the first UK company to manufacture ECLS manikin-based simulators.
Founder & Chief Executive — Sagar Haval
Sagar Haval has spent twenty-five years in the field of perfusion and ECMO — a career that began at the bedside and has grown into invention, engineering and company-building on a global scale.
He graduated first in his class in Perfusion Technology from Rajiv Gandhi University, Bangalore, in 2005, and joined Narayana Hrudayalaya Hospital, one of India's highest-volume cardiac centres. In 2006, finding no structured ECMO programme in place, he designed the hospital's ECMO circuit and protocols from scratch and became its first, unofficial ECMO Coordinator — the hospital's first ECMO patient survived under his direct care that year. He went on to build an entire cardiac surgery and perfusion service from nothing at Apollo BSR Hospital, Bhilai, in a region that had never had one, and was ranked first nationally in India's Perfusion Certification in 2009.
As a Global Trainer with Maquet from 2010, Sagar led the transformation of ECMO provision across South Asia and Southeast Asia, growing the region from fewer than five active centres to more than a hundred within five years, and personally delivering over 2,000 training sessions. In 2013, he introduced the first ECMO simulation performed on stage in India — taking training out of the classroom and in front of the clinical community it was built to serve.
Moving to the UK in 2015, he performed the country's first Normothermic Regional Perfusion (NRP) simulation and built ECMO and NRP simulation access across the UK and Ireland. It was this closeness to the training room that led him, from 2018, to begin independently developing his own simulation equipment — the origin of The Simulator Company, which he co-founded with his wife, Babita Haval, in London in 2019, as the first UK company to manufacture manikin-based ECLS simulators.
Sagar is recognised as the world's first clinical perfusionist and ECMO expert to invent his own medical technology and bring it directly to the global market. Under his leadership, The Simulator Company has released 19 products — the majority of them world firsts — and brought more than 300 innovations to life, protected by multiple patents granted across the United Kingdom, the United States and Europe. In 2023, he founded a second company, Innovatr Ltd, to develop next-generation implantable cardiac devices, medical AI and medical robotics, and in 2026 established the ECMO Simulation Academy to set the global standard for simulation-based ECMO and perfusion training.
In 2025, he received the Titan Innovation Award for Innovation in Medical Technology, and was personally invited by His Majesty King Charles III to the Royal Garden Party at Buckingham Palace — recognition of his contribution to British medical innovation.
