What Tornyol does

Tornyol builds micro-drones that kill mosquitoes. We use smartphone microphones, car park assist sensors and some clever DSP and control to transform 40-gram toy drones into mosquito killers. Because these drones are so cheap and fast, we will lower the cost of mosquito control by 100x which will enable the eradication of mosquitoes from cities, saving more than a million people each year from Malaria, West Nile, Dengue, etc.

Micro-drones that kill mosquitoes

What is your company going to make? Please describe your product and what it does or will do.

We build micro-drones that hunt and kill mosquitoes using a combination of off-the-shelf sensors - like smartphone microphones and car park assist sensors - and advanced digital signal processing and drone control. Our drones weigh 40 grams, are cheap to produce, and can be deployed quickly to drastically lower the cost of mosquito control in cities.

Where do you live now, and where would the company be based after YC?

We live in Paris, Île-de-France, France, and the company is based here. After YC, we would continue to be based in Paris.

Explain your decision regarding location.

We live and work in Paris where we have access to engineering talent and a vibrant startup scene. It's also close to markets where mosquito-borne diseases are a serious problem, aiding product development and testing.
