Edinburgh-based Danu Robotics has raised a $5 million late-seed round to bring H.E.R.O. to market, a robot that sorts waste using artificial intelligence. The six years of work behind the project were reported by TechCrunch on October 9, 2026.
Six years of work and $5 million
Danu Robotics was founded by Amy Ma. She previously worked as a software developer at a London bank, where she discovered that the building's waste-sorting system did not work in practice: separately collected recyclables were dumped straight into the general trash. That observation led her into the recycling industry. Dumping separately collected waste into the general garbage stream is a simple but widespread example of a break in the recycling chain. It was exactly such an ordinary observation that sparked the six-year project.
Since then, the company has spent six years developing a robot called H.E.R.O. It has now raised $5 million for the commercialization stage — late-seed, the round when a startup raises money on the eve of bringing a product to market.
Over the six years, the company built not only the robot's mechanical components but also the software platform that controls it. The raised funds will go precisely toward that goal — bringing H.E.R.O. to market.
Gripper arm — what sets it apart from rivals
H.E.R.O.'s gripper differs from competitors' suction systems: companies like Glacier and RecycleEye separate waste by suction. The gripper lifts recyclable items from the conveyor and pulls them out of the sorting stream. Both suction systems and the gripper serve the same purpose — extracting recyclables from the conveyor flow. Danu chose a two-armed design, built to retrofit existing manual sorting lines.
Another aspect of the two-armed design is compactness. According to the company's official website, the robot occupies less than one meter of conveyor. That lets facilities move toward automation without expanding their production floor — simply by adding the robot to the existing line. Retrofitting means the facility adds the robot to its line without fully upgrading it.
According to Danu Robotics' official website, the two-armed robot retrofits into existing manual sorting facilities and requires less than one meter of conveyor.
The robot's software is built on artificial intelligence and keeps improving: the system raises its sorting accuracy in the course of operation. This approach is useful where waste types vary from region to region — the algorithm adapts to the local waste stream. The AI model learns to recognize new waste types during operation and steadily improves sorting accuracy. The robot is therefore not limited to a single program: the system updates its work as it operates.
Business numbers: contracts and the market
The company already holds signed contracts worth $500,000. The total value has been disclosed — $500,000 — while the number of contracts has not. In addition, letters of intent have been received from two large customers, and the sales pipeline holds more than 200 prospective clients. The target market is the recycling-sorting segment in Europe and North America, estimated at $20 billion.
By founder Amy Ma's calculations, a single installed system could bring a facility $485,000 in additional annual revenue. The upfront investment is $160,000, with annual maintenance costs of $24,000. Under this model, the revenue pays back the upfront cost in under a year.
The company's commercial performance is still at an early stage: $500,000 in signed contracts and letters of intent from two large customers. The more than 200 candidates in the sales pipeline form a reserve base for future contracts. $20 billion is the company's announced estimate of the total market size in Europe and North America. These two regions are the company's initial target markets. The market-size estimate explains why the company is focusing on exactly these two regions.
The signed contract volume ($500,000) is small compared with the more than 200 candidates in the pipeline — the company's commercial activity is only just beginning.
On the Startup Battlefield 200 stage
Danu Robotics will take part in TechCrunch Disrupt, held October 13–15 at the Moscone Center in San Francisco, as a Startup Battlefield 200 participant. The company is among the 200 startups selected for the program. In the Battlefield program, early-stage startups present their products to investors and the media.
