We are a small Estonian project developing a mechanical drone defence net system to protect buildings and people from accidental drone collisions.

Our solution stops or neutralises drones weighing up to 300 kg before they reach a building – preventing up to 90% of structural damage.

A patent application has been filed and we now need funding to bring in experts, build the first working prototype and carry out real-world tests.

I have been following the war in Ukraine for a long time and have seen how drones have changed the battlefield. In the summer of 2025, I visited Ukraine and saw with my own eyes how residential buildings that had been hit were destroyed not by direct attacks, but by drones that had crashed accidentally.

These are drones that have been hit by air defences and then crash uncontrollably into urban or residential areas.

From that moment, one thought began to run through my mind:

is it possible to physically protect a building before a drone hits it?

I have developed a drone defence net system that operates either automatically or manually in the event of a threat. It creates a temporary protective net around the building or in front of the desired sides, which stops the drone or causes it to explode before it hits the structure. The explosion occurs 8–20 metres away from the building – resulting in visual damage rather than a structural disaster.

The protective net is mechanical, easy to activate and suitable for residential, industrial and public buildings alike.

If a drone hits the net, damage to the building is reduced by up to 90%.

What strikes me is that, in reality, we all have the capacity to protect ourselves.

At a reasonable cost, it is possible to create a system that protects everyone’s home and life.

The protective net is not a weapon – it is a safety measure that helps prevent accidental tragedies and accidents causing major damage.

The aim is for such protection systems to become part of the everyday urban environment in the future – invisible in daily life, but there when they are truly needed.

Today we have:

• a clear vision and technical design,
• 3D models and drawings,
• and a patent application filed, which provides initial legal protection across Europe.

We have discussed the solution with structural engineers and worked out how the protective net can be fitted to different types of buildings without spoiling the architecture or the cityscape.

The next step is to build a working prototype and test it in a real-world environment.

To do this, we need funding to cover:

• materials and mechanical components,
• tests,
• the work of engineers and experts,
• and the preparation of the first demonstrations.

If this stage is successful, we can begin product development and certification and bring the protective net to market.

Team

An Estonian inventor with an interest in developing technical systems and mechanical solutions. The idea was conceived in Ukraine in 2025, when the inventor witnessed first-hand the consequences of drone strikes on civilian buildings.

An Estonian civil engineer is currently also involved in the project, helping to assess the system’s suitability for various buildings and structures. In addition, negotiations are underway with various experts, including those in the defence industry and the field of customer relations.

We will mention you on our blogs, website, social media and at various public events where possible.

We should have started this four years ago.

Drone warfare is a modern reality and accidental strikes can occur in any country.

If we don’t develop these solutions before they’re actually needed, it will already be too late.
