Top Deep Tech Startups In Singapore To Watch In 2027

Singapore has more than 4 500 tech startups and around 500 venture capital firms, according to the Ministry of Trade and Industry. Not all of them are building apps or the next big software platform. Some are developing underwater robots, satellite engines and sensors that can map what lies beneath the ground without drilling.

These businesses can take years of research and engineering to develop, but their technology could eventually find its way into industries around the world.

Why Singapore Keeps Producing Deep-Tech Startups

Singapore has committed S$37 billion to research, innovation and enterprise between April 2026 and March 2031, roughly 1% of its GDP. Its universities, particularly the National University of Singapore (NUS) and Nanyang Technological University (NTU), alongside government research agency A*STAR, help turn scientific research into commercial ideas.

The government also supports early-stage businesses through schemes such as Startup SG Equity, which co-invests with private investors in eligible deep-tech startups. This gives research-heavy businesses another route to funding as they develop technology for markets beyond Singapore.

What Is Singapore’s Deep-Tech Scene Actually Building?

The country’s startups are working across a range of fields, from robotics and satellite communications to quantum technology and healthcare. Some are making machines that can inspect underwater infrastructure, while others are developing medical wearables or equipment for more efficient satellite operations.

Quantum technology is another growing area, although it covers quite different things. Quantum sensors use the behaviour of atoms to make extremely precise measurements, quantum communications explore ways to exchange encryption keys while detecting interception attempts, and quantum computing uses quantum systems to process information. Each requires specialist research and engineering, meaning many of these businesses are still developing and testing their products.

1. BeeX

BeeX develops autonomous underwater drones that inspect offshore infrastructure, ports and other difficult-to-reach structures. Its A.IKANBILIS drone is designed to carry out inspections without the large vessels and crews traditionally needed for underwater work.

Founded by NUS graduates Grace Chia and Goh Eng Wei in 2018, BeeX has since completed more than 18 000 hours of commercial and defence deployments worldwide, according to the university. In June 2026, it raised US$7.7 million in Series A funding led by Monk’s Hill Ventures to expand its fleet and operational reach.

2. Eureka Robotics

Eureka Robotics develops software and robotic systems for manufacturing tasks that require a high level of accuracy. Its technology combines robotic control with 3D vision, allowing machines to handle delicate components and carry out precision inspections.

The company began as an NTU spin-off, founded in 2018 by Professor Pham Quang Cuong and Dr Hung Pham. Its US$10.5 million Series A round in December 2024 was led by B Capital, with Airbus Ventures among the investors. The funding was intended to support the development of its robotics products and expansion into international markets.

3. Aliena

Aliena develops electric propulsion systems for small satellites, using plasma to generate thrust without conventional chemical rocket fuel. Its engines are designed to help satellites manoeuvre and maintain their orbits, including in very low Earth orbit, where atmospheric drag can gradually pull them down.

Founded in 2018 by NTU researchers Mark Lim and George-Cristian Potrivitu, the company raised US$5.6 million in 2024 to support its growth and development of its testing and production capabilities.

4. Transcelestial

Transcelestial develops laser-based wireless communication equipment that can transmit data through the air without underground fibre-optic cables. Its CENTAURI product range is designed to provide high-speed connections for telecommunications networks, including links between buildings and mobile infrastructure.

Rohit Jha and Mohammad Danesh founded Transcelestial in Singapore in 2016. In November 2025, the company raised a further US$9.7 million, bringing its total announced funding to US$34.7 million. The investment will support its expansion into Japan, including disaster recovery connectivity, alongside further development of its defence and space communications technology, according to the company.

5. Atomionics

Atomionics develops Gravio, a quantum gravity sensor that uses extremely cold atoms to measure tiny variations in Earth’s gravitational field. Different underground materials have different densities, creating small changes in gravity that the device can detect and use to build maps of underground structures.

For mining and energy companies, this could offer another way to investigate potential resources without relying entirely on traditional drilling methods. Atomionics raised US$12.7 million in September 2025 in a round led by Paspalis, with BHP Ventures and In-Q-Tel among the investors.

6. SpeQtral

SpeQtral is developing satellite-based quantum key distribution (QKD), a technology that uses the quantum properties of light to help two locations exchange encryption keys while making interception attempts detectable. The company was spun out of NUS’s Centre for Quantum Technologies and is working towards using satellites to extend quantum communications beyond the reach of conventional fibre networks.

Its SpeQtre satellite launched in November 2025 in collaboration with the UK’s RAL Space. In August 2026, operational control transferred to SpeQtral as the satellite entered its quantum experimentation phase, bringing the team closer to testing space-to-ground quantum communications.

7. Horizon Quantum

Horizon Quantum develops software that allows programmers to build applications for quantum computers without having to work directly with the technical differences between individual machines. Its Triple Alpha development environment lets developers write, compile and optimise quantum programs across different hardware platforms.

Founded by Joe Fitzsimons in 2018, the company began operations in Singapore in 2019. A major milestone came in March 2026, when it completed its business combination with dMY Squared and began trading on Nasdaq under the ticker HQ. It’s now publicly listed, but remains a Singapore-founded company developing software infrastructure for quantum computing.

8. Entropica Labs

Entropica Labs develops software tools for quantum computing, including technology designed to help make quantum systems more reliable. Its work includes quantum error correction, which helps quantum computers identify and manage errors during calculations. These errors are a major challenge because quantum systems are particularly sensitive to disturbances.

Founded in Singapore in 2018, Entropica Labs was spun out of the Centre for Quantum Technologies. Its Series A funding round, initially announced at US$4.7 million, was later extended to US$5.5 million in 2024, according to the company’s funding announcement, with investors including Wavemaker Partners, LIFTT and State Farm Ventures.

9. Aevice Health

Aevice Health develops AeviceMD, a wearable smart stethoscope designed to monitor respiratory health outside traditional clinical settings. The device records lung sounds and tracks measurements such as heart and respiratory rates, helping healthcare professionals monitor people with long-term conditions such as asthma.

The NTU spin-off received regulatory approvals for AeviceMD in Singapore and the US before raising a US$7 million Seed Plus round in August 2024. The investment was led by Coronet Ventures and intended to support its expansion into markets including the US, Japan and Singapore.

10. Biorithm

Biorithm develops femom, a remote maternal monitoring platform designed to help healthcare professionals follow pregnancies outside hospital appointments. Its platform brings together maternal and fetal monitoring information, patient-reported symptoms and a digital dashboard that clinicians can use to review patient data.

The company is a medical technology spin-off from NTU, founded by doctors and engineers. Its clinical-grade fetal-maternal monitoring device is still in the clinical investigation phase, so the technology is not yet a fully cleared product for general clinical use.

Different Stages, Different Possibilities

These businesses are at different stages of development; some already have technology being deployed in commercial settings, while others are still testing products that could take years to reach wider markets.

What connects them is the research behind their work and the industries they’re trying to change. Whether it’s improving how satellites move through orbit, making underground exploration less dependent on drilling or helping doctors monitor patients remotely, Singapore’s deep-tech startups are developing technology that reaches well beyond the usual startup scene.
