In the financial year ending March 2025, Detect Technologies earned ₹51 crore (about $5.3 million) selling software that watches oil refineries, steel mills and chemical plants for danger and inefficiency — and lost ₹31.4 crore doing it, nearly as much as it made. That gap has not stopped Accel, Elevation Capital and Prosus Ventures from backing the Chennai-founded startup for close to a decade, betting that a platform which catches a corroding pipe or an unsafe worker before a human inspector does is worth funding through years of red ink.
Detect began in 2013 as a corrosion-measurement experiment inside an IIT Madras lab, turned into a drone-and-sensor hardware company, nearly stalled on the economics of selling one-off devices, and then rebuilt itself as a recurring-revenue AI platform now used by Shell, Tata Steel, ExxonMobil and Adani Group. What follows is what is actually documented about how it got there, what it earns, and where it is exposed.

What they do
Detect Technologies builds an industrial AI platform, marketed as T-Pulse, that heavy industry uses to watch its own operations for the things that cause accidents, shutdowns and lost output: corroding pipes, workers not wearing safety gear near moving machinery, equipment drifting toward failure, and maintenance shutdowns running over schedule. It sells to oil and gas majors, steel mills, power plants, chemical and fertiliser units, and, increasingly, similar heavy-asset operators outside India. The pitch is not a single gadget but a layer of continuous, camera- and sensor-fed intelligence sitting on top of plants that were mostly monitored by rounds of human inspectors and paper checklists.
The origin
The company’s first idea was narrow and technical, not entrepreneurial. Between 2012 and 2014, Tarun Mishra, then a student, worked with Professor Krishnan Balasubramanian at IIT Madras’s Centre for Non-Destructive Evaluation on an ultrasonic method for measuring corrosion inside pipes without cutting them open. The insight that turned a lab technique into a company was financial rather than technical: a single undetected pipeline leak could cost an oil and gas facility an estimated ₹12–15 crore a day in lost production and cleanup, a number large enough that even a modest improvement in detection would pay for itself many times over. Mishra teamed up with fellow IIT Madras students Daniel Raj David, Harikrishnan A S and Karthik R, and the group incorporated Detect Technologies Private Limited on 23 February 2016, working out of the IIT Madras research park. David, then a final-year student, pitched the idea at a TiE Chennai event in November 2016 before the company had much more than the original sensor concept and a small founding team.
The struggle years
Detect’s first two products were physical devices: Gumps, a sensor for continuous pipeline corrosion and leak monitoring, and Noctua, a drone-based system for inspecting tanks, flare stacks and other hard-to-reach industrial assets. Both worked technically and found early customers, but the business underneath them was fragile. Hardware sales are one-time and capital-intensive, and by the founders’ own later account, less than 30% of Detect’s revenue in this period was recurring — meaning the company had to keep winning new equipment orders from scratch each year rather than building a base of renewing customers, a treadmill that is especially punishing for a small team competing for enterprise budgets against incumbent instrumentation vendors. Compounding this, Detect spent roughly two years, from around 2017 to 2019, testing overlapping ideas across inspection, safety and efficiency use cases before committing to safety and productivity monitoring as the core of the business, a period of genuine drift about what the company was actually for. The resolution was a deliberate pivot away from selling boxes and toward selling a subscription: the hardware became a data-collection front end for a growing software platform, rather than the product itself.
The turning point
The pivot needed a proof point, and Detect got one in 2017, when it landed its first industry-sponsored pilot with what the company and its investors have described as the largest refinery in the world, alongside selection into Shell India’s first startup cohort. Before that pilot, Detect was an unproven campus spin-off with a lab-grade sensor and no reference customer of scale; a rejection or a stalled trial at that stage would have left it competing for smaller, slower-paying industrial clients indefinitely. After it, the company’s technology was validated inside one of the most safety-conscious and highest-throughput operating environments in the industry, and adoption compounded quickly: by 2018, Detect’s systems were deployed across more than 80% of large oil and gas facilities in India, according to Axilor Ventures, one of its early backers. That single credential — a top-tier global refiner willing to run and vouch for the technology — is what let Detect move from being one of many campus deep-tech projects to a vendor that Adani, Vedanta, Aditya Birla Group, NTPC, GAIL and Hindustan Petroleum would also sign.
The money behind it
Detect has raised capital in stages that track its shift from a hardware idea to a funded software platform, rather than in one dramatic round:
- Seed, August 2017: undisclosed amount from Axilor Ventures and other early backers, following Detect’s admission to Axilor’s incubation programme that year (Inc42 funding data).
- Series A, 19 November 2018: $3.3 million led by Elevation Capital, then still operating as SAIF Partners (Inc42; Entrackr).
- Bridge round, 29–30 June 2021: $12 million led jointly by Accel and Elevation Capital, with Bharat Innovation Fund, BlueHill Capital and Axilor Ventures participating, plus Stride Ventures as a venture-debt partner (Entrackr; Detect Technologies’ own announcement).
- Series B, 13–14 July 2022: $28 million led by Prosus Ventures, with Accel, Elevation Capital, Shell Ventures, Bharat Innovation Fund and Bluehill Capital also participating — the company’s largest round and its first with a global growth investor in the lead (Inc42; Detect Technologies’ announcement; YourStory).
Total funding raised is reported as roughly $43.3 million across six rounds as of July 2022 by Inc42, and $45.7 million across seven rounds by Tracxn; the gap is likely explained by how each tracker treats a small ₹10,000 government grant from the Ministry of Electronics and Information Technology recorded in January 2022. Inc42 puts Detect’s post-money valuation at $137.64 million as of the July 2022 Series B, the last figure tied to an actual priced round; Tracxn’s own 2026 estimate marks the company’s current value lower, around ₹1,090 crore (roughly $113 million at $1 ≈ ₹96.0, the rate as of 18 September 2026 per Trading Economics), reflecting the broader markdown in growth-stage valuations since 2022 rather than a new funding event. No priced round has been publicly disclosed since July 2022.
What each lead backer changed: Elevation Capital (as SAIF Partners) backed the original hardware-era Series A in 2018, when Detect was still a single-product corrosion-sensor company; Accel co-led the 2021 round that funded the pivot toward software and international sales teams; Prosus Ventures, a growth-stage global investor, led the 2022 Series B that financed Detect’s push into North America and Europe, including a new Houston, Texas hub.
How it makes money
Detect’s revenue model has moved from selling hardware outright to selling a subscription to a software platform that hardware feeds:
- Money in: enterprise subscriptions to T-Pulse, the SaaS platform covering asset monitoring, hazard and compliance detection, and turnaround/maintenance management; earlier one-time hardware sales of Gumps sensors and Noctua drones now function more as an entry point than the main revenue line.
- Costs out: plant-level sensors, cameras and drone hardware; the computer-vision and AI engineering team; and a direct enterprise sales force covering long, technical sales cycles with oil and gas, steel and chemical customers across India, North America, Europe, the Middle East and Southeast Asia.
- Where the margin sits: in the recurring software layer rather than the hardware — the company has explicitly said its early, hardware-heavy revenue mix was “lumpy” with under 30% recurring, and its subsequent strategy has been to grow the share of revenue that renews automatically each year.
- The part people get wrong: Detect is often described as a drone or sensor company because those were its first products; its current business is closer to an enterprise safety-and-productivity SaaS vendor that happens to also sell some of the hardware that captures its data.
- Take rate / per-unit pricing: not publicly disclosed by the company in any source found for this piece; that detail is omitted here rather than estimated.
The numbers
Only two fiscal years of revenue and profit/loss could be verified with confidence from a consistent source (Inc42’s financial-filings-based estimates); an additional multi-year table sourced during research produced figures that could not be reconciled with these or with the company’s known loss-making, growth-stage status, so it has been excluded rather than reproduced.
| Metric (₹ crore) | FY24 (year ended 31 Mar 2024) | FY25 (year ended 31 Mar 2025) |
| Revenue | 35.9 | 51.0 |
| Net profit / (loss) | (32.1) | (31.4) |
| Total expenses | — | 78.5 |
| Total assets | — | 171.1 |
- FY25 revenue: ₹51.0 crore, up 41.8% year-on-year from ₹35.9 crore in FY24 (Inc42 financial estimates).
- FY25 net loss: ₹31.4 crore, marginally narrower than FY24’s ₹32.1 crore loss even as revenue grew by more than 40% (Inc42).
- FY25 net margin: approximately -69.1%, meaning the company spent roughly ₹1.69 for every ₹1 of revenue it booked (Inc42).
- FY25 total expenses: ₹78.5 crore, up 17% year-on-year, growing more slowly than revenue (Inc42).
- FY25 total assets: ₹171.1 crore, down 13% year-on-year, consistent with a company spending down cash reserves raised in 2022 rather than raising fresh capital (Inc42).
Where the money comes from
Detect does not publish a formal segment-wise revenue split, but the documented pattern of its growth shows where the business actually sits:
- By industry: concentrated in heavy, hazard-prone process industries — oil and gas, steel, power, chemicals, fertilisers and, more recently, pharmaceuticals and cement — where unplanned shutdowns and safety incidents carry the largest direct cost (Axilor Ventures).
- By geography: built first for the Indian market, where it reached over 80% of large oil and gas facilities by 2018, then expanded internationally; Elevation Capital reported that within about two years of having no international presence, nearly half of Detect’s revenue was coming from outside India, with operations extended into the United States, Canada, the Middle East and Southeast Asia and a dedicated North American base opened in Houston, Texas after the 2022 raise.
- By product line: the surprise is how far the mix has moved from Detect’s founding product. The company was built around Gumps, a pipeline corrosion sensor, but its most cited outcome metric today is a 90% decrease in safety violations at customer sites, reported by Accel — a workplace-safety and compliance result, not a pipeline-integrity one, suggesting the safety and productivity layer of T-Pulse now carries more of the commercial story than the original corrosion-detection use case.
The risks
- Concentration in a cyclical customer base. Detect’s named customers — Shell, ExxonMobil, Adani Group, Vedanta, Tata Steel, Reliance, NTPC, GAIL, Hindustan Petroleum — are almost all large oil, gas, metals and power operators whose maintenance and technology budgets move with commodity prices and capital-expenditure cycles. Enterprise sales cycles in this sector are already long; a downturn in oil and gas or steel capex would likely delay contract renewals and new deployments rather than cause an outright loss of customers, but it would slow the growth the company needs to close its loss gap.
- Cash burn continuing without a fresh disclosed round. Detect’s FY25 net loss of ₹31.4 crore against ₹51.0 crore of revenue means it is still spending close to ₹1.70 for every rupee earned, eight years after its Series A. Its last disclosed priced funding round was in July 2022; FY25 total assets fell 13% year-on-year, consistent with the company running down the cash from that round rather than replenishing it, which puts pressure on it to either reach breakeven or raise again on terms shaped by the broader markdown in growth-stage valuations since 2022.
- A shrinking team even as revenue grows. Headcount has moved from roughly 140 employees in mid-2021 to about 390 around the 2022 raise and down to 317 as of 31 August 2025, an 8% year-on-year decline even as FY25 revenue grew 41.8% (Tracxn). That combination can reflect genuine efficiency gains from the software pivot, but a shrinking bench also risks straining delivery and support as the company tries to hold and expand large multinational accounts across multiple continents.
The takeaway
Detect’s most transferable lesson is not about artificial intelligence or industrial safety specifically; it is about recognising, and acting on, which part of your own product is actually the business. The company spent its first several years building genuinely useful hardware — a corrosion sensor, an inspection drone — and only became fundable at scale once its founders accepted that the sensors were a way to collect data for a subscription business, not the business itself. That kind of pivot is uncomfortable because the hardware is the more visible, more patentable, more demo-able achievement; the software is the less glamorous layer that actually renews. The founders who make that switch early, as Detect’s did around 2019, buy themselves the years of runway needed to prove it out in a market — industrial safety — that would otherwise never have taken a campus drone project seriously.
