The Ahmedabad-based spacetech company has just closed a $2.2 million seed funding round led by Unicorn India Ventures, taking its total funding raised to $5.5 million since its founding in 2023. The round also saw continued backing from Merak Ventures, Java Capital, IIMA-CIIE, and deep-tech investor Manish Gandhi — all of whom had participated in the company’s earlier pre-seed round as well.
For a three-year-old startup building actual satellites, this kind of investor loyalty across multiple rounds says a lot.
The Startup — What Is SatLeo Labs Building?
SatLeo Labs was founded in 2023 by Shravan Bhati, Ranendu Ghosh, and Urmil Bakhai. Bhati serves as CEO, Ghosh as CTO, and Bakhai as CSO. All three bring technical depth to a problem that sits at the intersection of hardware engineering, data science, and climate technology.
The company is building a constellation of microsatellites that capture both thermal infrared and visible light imagery from Low Earth Orbit (LEO). In plain language — they are putting small satellites in space that can see heat. Not just photographs of the Earth’s surface, but actual temperature maps showing where heat is building up, where it is escaping, and where it is causing damage.
SatLeo’s platform enables applications across defence, agriculture, disaster response, and urban climate intelligence, helping governments and enterprises make data-driven, sovereign decisions and build climate-resilient systems at scale.
That is a wide application base — and deliberately so. Thermal data from space is genuinely useful across multiple sectors, which gives SatLeo a diversified commercial opportunity rather than dependence on a single vertical.
The Technology — What Makes TAPAS-1 a Big Deal?
The most important technical milestone SatLeo has achieved so far is the development of TAPAS-1 — its first experimental thermal payload designed for satellite integration.
The company achieved this milestone by designing and delivering TAPAS-1 for satellite integration within six months, reaching TRL-8 readiness and positioning the system for launch.
For those unfamiliar with the term — TRL-8 (Technology Readiness Level 8) is the second-highest level in the technology maturity scale used by space agencies worldwide. It means the system has been fully tested and qualified in its final form. The only step remaining is an actual launch. For a startup that is barely three years old, reaching TRL-8 on a thermal satellite payload is a genuinely impressive engineering milestone.
The startup develops microsatellites with dual-band thermal sensors (MWIR/LWIR) to detect temperature variations, providing actionable insights for agriculture, urban planning, and climate monitoring. The dual-band approach — using both Mid-Wave Infrared (MWIR) and Long-Wave Infrared (LWIR) sensors — gives SatLeo’s data a level of precision that single-band thermal systems cannot match.
The Team — From 8 People to 30 in 12 Months
One of the clearest signs that a startup is transitioning from ideation to execution is rapid team growth. SatLeo Labs shows exactly that pattern.
Over the last 12 months, the company has grown its team from 8 to 30 members, bringing together engineers and researchers with deep expertise in satellite missions, thermal sensing, and AI-driven geospatial analytics.
Going from 8 to 30 people in a year — while simultaneously building a satellite payload, running city-level pilot projects, and raising a seed round — is operationally demanding. It suggests the founding team has figured out not just the technology but also the basics of company building.
The Pilots — Real Deployments, Real Impact
One of the things that separates SatLeo from many deep-tech startups at the seed stage is that it is already generating real-world data through active pilot projects — before its satellite constellation is even launched.
SatLeo has initiated pilot projects focused on urban heat island and air pollution monitoring in cities such as Ahmedabad and Tumakuru, with an estimated impact on over 4,00,000 citizens.
Urban heat islands — zones within cities that are significantly hotter than surrounding areas due to concrete, reduced vegetation, and human activity — are a growing public health concern in India. Identifying them with precision requires the kind of thermal mapping that SatLeo’s technology enables. The fact that two Indian cities are already using this data gives the company credibility that no marketing pitch can manufacture.
The Commercial Pipeline — $42 Million in LOIs
Here is the number that should really get the attention of every startup founder and investor reading this.
SatLeo has built a strong commercial pipeline, with Letters of Intent (LOIs) growing from approximately $15 million to over $42 million within the year, reflecting strong market demand for space-based thermal intelligence solutions.
Let that sink in for a moment. A startup that has not yet launched its first satellite has convinced customers to sign letters of intent worth over $42 million. That kind of commercial validation at the pre-revenue stage in deep-tech is rare. It means the founders have done the hard work of identifying real buyers, convincing them that the technology will work, and getting written commitment from them ahead of launch.
For Indian startup founders wondering how to build investor confidence in a deep-tech company — this commercial pipeline strategy is worth studying closely.
The Investors — Why Unicorn India Ventures Led This Round
Bhaskar Majumdar, Managing Partner at Unicorn India Ventures, said the firm strongly believes that space is where the next wave of technological innovation will emerge. He noted that SatLeo’s differentiated product — combining thermal and visible satellite data — generates high-value real-time insights, positioning the company to become a key long-term player in the spacetech ecosystem.
Importantly, this is Unicorn India Ventures’ third spacetech investment — which tells you this is a deliberate portfolio thesis, not a one-off bet. When a fund puts capital into a sector three times, it has usually done deep diligence on the market opportunity and believes the sector is entering a growth phase.
The presence of IIMA-CIIE — the Centre for Innovation, Incubation and Entrepreneurship at IIM Ahmedabad — is also noteworthy. CIIE is one of India’s most respected deep-tech incubators, and its continued participation in the seed round signals institutional confidence in both the technology and the founding team.
The Roadmap — What Happens Next
With $2.2 million freshly in the bank and a total war chest of $5.5 million, SatLeo Labs has a clear 12-month agenda.
Over the next 12 months, SatLeo plans to focus on satellite launch readiness, scaling its technology platform, and expanding commercial deployment.
In startup terms, that translates to three parallel tracks running simultaneously — getting TAPAS-1 integrated into a satellite and launch-ready, scaling the AI platform that turns raw thermal data into actionable intelligence for clients, and converting the $42 million LOI pipeline into actual signed contracts and revenue.
India’s Spacetech Opportunity — The Bigger Picture
SatLeo Labs is raising money and building satellites at a pivotal moment for India’s space sector. The government’s decision to open space activities to private players through IN-SPACe has created a genuine startup ecosystem around space technology — and SatLeo is one of its more interesting products.
India’s space economy was expected to touch $13 billion in 2025. India’s space sector funding hit a peak of $130.2 million in 2023 — a 32.9% rise from 2022 — before falling 55% to $59.1 million in 2024, even as the government approved a ₹1,000 crore fund for spacetech startups.
The funding dip in 2024 was a market correction — investors got more selective after an early wave of enthusiasm. The startups that are raising in 2026 are generally the ones that survived that correction by showing real technical progress and real commercial traction. SatLeo Labs fits that description precisely.
