What is ThinkSono?

ThinkSono has built the right software to train even novice users how to give a proper ultrasound. Additionally, the startup based in London is building the world’s first software that detects deep vein thrombosis (DVT) with nurses in as little as 5 minutes

Ultrasound for Everyone

Our mobile app interacts directly with the ultrasound scanner, enabling simultaneous scanning and AI-guidance for training. Exams are uploaded to the Cloud Dashboard to receive feedback from an expert or colleague.

All healthcare professionals can now detect DVT

AutoDVT enables all healthcare professionals to perform deep vein thrombosis (DVT) scans at the point of care. It’s the world’s first non-invasive solution that can be driven at the point of care instead of through an elaborate testing process. Nurses can now detect DVT in as little as five minutes.

ThinkSono software deployed in 11 hospitals across Europe

8 hospitals in the UK, 2 in Germany, and 1 in Greece.

Investment overview

ThinkSono is a startup based in London. We are currently building the world’s first software that can help any healthcare provider detect deep vein thrombosis (DVT) in as little as 5 minutes. You can become part of the team by investing in our company during our second funding stage. We’re currently accepting investments but the round won’t last long. Here are the details:

  • Investment amount
    We are raising a $3M round but ⅓ of that amount is already reserved.
  • Previous funding
    We’ve previously raised $4.5 million from top venture capital firms that include Speedinvest, Entrepreneur First, TinyVC, Calm Storm Ventures, as well as angel investors.
  • Reason for raising capital
    We are seeking investments to commercialize ThinkSono AI software to the world, starting with our expansion to the United States market.
  • Team
    Our team is led by Co-Founder and CEO Fouad Al Noor as well as Co-Founder and CTO Sven Mischkewitz.
  • Key Partnerships
    We have partnered with Clarius, a top vendor of ultrasound equipment in order to provide commercial distribution opportunities
  • The future of our success depends largely on our ability to build and scale effectively. There are no guarantees but ThinkSono has been around since 2016 and we are now developing something that is even more unique and helpful to the healthcare industry.
  • Competition. There are no guarantees that more competitors won’t enter the space. However, we have built a sustainable solution and are far ahead in an AI world that takes time for the solutions to learn and develop.
  • We’re entering new markets. While we feel good about the expansion to the U.S. market, there are no guarantees and new markets present the risk that we will not get it right for a slightly different audience. However, healthcare is pretty universal.
DVT is a significant problem for the NHS. Not only from a financial perspective, but also a clinical perspective...Pathways for DVT is consequently very time consuming because the patient has to be sent to radiology for the performance of the scan. Enabling nurses, GP’s and other non-specialists to diagnose DVT accurately at the point of care would be extremely useful for the NHS and much more convenient for patients.

The burden of deep vein thrombosis is significant for the National Health Service and one particular problem is that DVT is suspected much more often than it is found. The potential for non-experts to perform diagnostic ultrasound could dramatically improve DVTR diagnostics pathways.

I'm excited about the technology and can see many applications for it. For example, rehab units and nursing homes frequently have multiple patients who need venous studies. Their solution is seldom efficient, and I could see every facility like this having a system so they can check their patients whenever they want.
