Startup Deep Dive : Block Armour — Rs 2.62 crore of revenue, dollar 53K of funding, and a decade of global cybersecurity awards

Block Armour has been rated a “Market Outperformer” by analyst firm GigaOm and named among the world’s top 25 cybersecurity innovations by Accenture — yet nine years after it was incorporated, the Mumbai-and-Singapore venture reported just ₹2.62 crore ($273,000, at $1 ≈ ₹96.0) in FY24 revenue and, per Tracxn, employed 14 people as of August 2026. That gap between the accolades and the balance sheet is the real story here: a startup that bet blockchain could fix enterprise cybersecurity’s oldest problem, won awards for the idea, and is still working out how far the idea travels commercially.

Total disclosed external funding, according to CB Insights and PitchBook, is $53.2K — one incubator investment from Airbus BizLab, dated 12 December 2017. No named venture round, no disclosed valuation, no IPO. What Block Armour has instead is a decade of pilots, partnerships and press mentions, a product that has been renamed and re-scoped more than once, and a set of MCA filings that show a company still searching for scale. This piece works through what is actually documented — no more, no less.

Quick facts

What they do

Block Armour builds Zero Trust network security software for enterprises, aimed at the moment a company’s employees, contractors and connected devices sit outside its traditional office network — on the road, on the cloud, or on a factory floor. Its platform, marketed as Secure Shield and aligned to the US National Institute of Standards and Technology’s Zero Trust framework, combines Software Defined Perimeter architecture (which hides a company’s servers from the open internet until a user is verified) with blockchain-based digital identity and TLS encryption, so every user and device is authenticated before it is allowed to see anything. The company sells to mid-size and large enterprises directly and, more often, through system integrators and cloud marketplaces — Oracle Cloud Marketplace, Microsoft Azure Marketplace, India’s Government e-Marketplace (GeM), Schneider Electric Exchange and PwC’s marketplace are all listed as go-to-market channels on its own site. A second product line, IoTArmour, applies the same identity approach to connected devices and industrial systems — smart-city sensors, factory equipment, autonomous-mobility hardware — where a compromised device is often the entry point for a wider breach.

The origin

Narayan Neelakantan spent roughly 16 years inside India’s National Stock Exchange, rising to Chief Information Security Officer and Head of IT Risk and Compliance, according to his own professional profile and an interview published on Insights Success. Sitting on that side of the table — defending one of the country’s most-attacked pieces of financial infrastructure — he watched, in his words, organisations “defend against tomorrow’s cyberattacks with yesterday’s technology,” a line he later gave to TechBullion in an interview dated 2 January 2018. Blockchain, then near its 2016-17 hype peak, offered him a specific technical answer: a way to issue digital identities to users and devices that could not easily be forged or replayed, layered on top of the Software Defined Perimeter approach that was already gaining traction in enterprise security circles. He recruited Abhijit Dhongade, who had led the NSE’s own security operations centre, as co-founder and CTO, and Floyd DCosta, an ex-Capgemini management consultant and IIM Bangalore alumnus with roughly 19 years in international business development, to help take the idea to market outside India. The three incorporated Block Armour Private Limited in Mumbai on 20 April 2017, positioning the company from day one as Singapore- and India-facing rather than purely domestic.

The struggle years

The company’s own account, and the outside data, both point to a business that has had to keep re-defining what it actually sells. In its first documented commercial phase, in and around 2018, Block Armour described its product simply as a “Blockchain Defined Perimeter” — a generic enterprise-security overlay. By the TechBullion interview’s own account, dated January 2018, that product existed only as a “limited release version,” running as pilots at two customers: an Indian media house and a financial exchange, with a further pilot planned at a Singapore financial institution. Two enterprise pilots, nearly two years after founding, is a thin base for a company chasing global cybersecurity budgets.

• 2016-2018: product framed narrowly around a “Blockchain Defined Perimeter” concept, validated by only two named pilot deployments in India (TechBullion interview, January 2018).
• Circa 2019: repositioning around IoTArmour, narrowing the pitch to IoT and industrial security specifically, aimed at smart cities and autonomous mobility (company materials, CIO Tech Outlook profile, 2019).
• By 2022-23: a further reposition to a broader Zero Trust Network Access platform (“Secure Shield”), explicitly mapped to the NIST Zero Trust framework — the positioning the company still uses in 2026 (GigaOm Radar Report coverage, 2023; company site).
• Leadership thinned out along the way: co-founder Floyd DCosta, the executive tasked with international business development, was already listed on Crunchbase as a co-founder of two other ventures — Space Armour and Blockchain Worx — by mid-2023, alongside his Block Armour role.
• Headcount has moved in the wrong direction for a company meant to be scaling: Tracxn recorded 24 employees in July 2024, PitchBook lists 18, and Tracxn’s most recent snapshot puts the number at 14 as of August 2026 — a fall of roughly 40% from the 2024 figure on Tracxn’s own numbers.
• FY24 financials, as compiled by Tofler from the company’s MCA filings, show a net profit margin of -3.86% and a return on capital employed of -645.55% — a company still running at a loss on a very small capital base (paid-up capital of ₹10.53 lakh) even as revenue grew.

None of this is a single dramatic near-death; nothing in the public record shows Block Armour ever ran out of money or shut its doors. What the record does show is a company that kept narrowing and re-widening its product story, lost part of its founding team along the way, and, by its most recent filed year, was still shrinking headcount while posting a loss — the slow-burn version of a startup struggle rather than the cinematic one.

The turning point

If there is one event that changed Block Armour’s trajectory, it is the company’s selection into Airbus’s BizLab accelerator programme, formalised with an incubator investment dated 12 December 2017 by CB Insights’ and PitchBook’s funding records. Company materials describe the selection as coming out of a pool of more than 150 applicants — a filter that, if accurate, marks the point where Block Armour stopped being a two-pilot regional security vendor and started being introduced to the kind of large industrial and aerospace buyers Airbus works with. The before-and-after is visible in the credentialing that followed within roughly a year: Accenture named Block Armour among its top 25 cybersecurity innovations worldwide in 2018, and the company says it was rated among the top 20 global cybersecurity startups in both 2017 and 2018. On the other side of that same year, the underlying business was still tiny — two pilot customers as of January 2018, no disclosed revenue figures for that period, and a total external funding base that, even eight years later, CB Insights puts at just $53.2K. The turning point bought Block Armour a global reputation years before it bought Block Armour a global revenue line.

The money behind it

• Total disclosed external funding: $53.2K — a single Incubator/Accelerator round, dated 12 December 2017 (CB Insights, PitchBook).
• Named backer: Airbus BizLab — the aerospace group’s startup accelerator, which selected Block Armour from a reported applicant pool of 150-plus companies and gave it access to Airbus’s industrial and aviation network (company materials; CB Insights).
• Named backer: Singapore Space & Technology Association — listed by CB Insights as a second investor/backer, consistent with Block Armour’s Singapore incorporation and its later space-cybersecurity work.
• No priced venture round on record. Crunchbase and PitchBook show one funding event; no Series A, B or later round is listed by either.
• No disclosed valuation at any point — the company has never announced, and no data provider lists, a post-money valuation.
• Capital base stayed small on the ground: the Indian entity’s authorised capital is ₹25 lakh and paid-up capital ₹10.53 lakh as of its latest MCA filing (Zaubacorp, Tofler) — roughly $11,000 of paid-up equity capital for a company operating across four countries.
• Borrowings rose sharply in FY24 — up 267.89% year-on-year, per Tofler’s reading of the MCA filing — suggesting the company has increasingly funded operations with debt rather than fresh equity.

What this means in practice: Block Armour appears to have been built and run largely on services revenue, non-dilutive accelerator support and founder capital, rather than on the venture-funding path most cybersecurity startups take. That is unusual for a company competing in a category — Zero Trust Network Access — where well-funded rivals routinely raise nine-figure rounds.

How it makes money

Block Armour does not publish pricing, so the take rate, per-seat fee or subscription tiers that most software companies disclose are simply not available here — a gap this piece will not fill with guesses. What is documented is the shape of the go-to-market model: the company does not primarily sell direct. Its own site lists Oracle Cloud Marketplace, Microsoft Azure Marketplace, India’s Government e-Marketplace, Schneider Electric Exchange and the PwC marketplace as channels, meaning a meaningful share of any deal likely passes through — and is split with — a platform or systems-integration partner rather than landing as pure Block Armour revenue.

• Revenue line, per MCA filings: IT consulting and support services (₹2.62 crore in FY24) — the filing category under which the company reports, rather than a separately broken-out “software licence” or “SaaS” line.
• Cost structure: a small, high-skill security engineering team (14-24 people across recent snapshots) is the likely main cost, consistent with a negative operating margin (-3.01%, FY24) even at modest revenue.
• Distribution cost is shared with partners by design — cloud marketplaces and system integrators (Oracle, Microsoft Azure, PwC, Schneider Electric) take a cut in exchange for reach the company could not otherwise afford on $53.2K of raised capital.
• “The part people get wrong”: award coverage (GigaOm, Accenture, ABI Research mentions) reads like the profile of a well-funded, fast-scaling vendor; the MCA filings tell a smaller and more constrained financial story. Both are true at once — recognition and revenue have not moved at the same pace here.

The numbers

Full multi-year profit-and-loss detail for Block Armour Private Limited sits behind paid MCA-data-aggregator subscriptions (Tofler, TheCompanyCheck); what is available in the free layer of those services, plus CB Insights, is summarised below. Figures are for the Indian entity only, in ₹ crore, and do not necessarily capture group-wide revenue across the Singapore and other overseas entities.

Two things are worth being explicit about. First, the exact FY23 revenue in ₹ crore is not independently disclosed in the free data available this session — it is backed into from the FY24 growth rate rather than sourced directly, so it is shown as an estimate rather than a hard figure. Second, the 23.57%-revenue/60.33%-profit growth pair cited by TheCompanyCheck is presented there without a specific fiscal year label; it is included because it independently corroborates the direction (growing revenue, improving-but-still-thin profit) that Tofler’s FY24 numbers also show, not because the two data points can be stitched into one clean three-year table. A genuinely complete three-to-four-year revenue and profit series would require a paid MCA filing pull, which was outside what could be verified this session — so this section is narrower than the ideal, by design, rather than padded with invented numbers.

Where the money comes from

Block Armour does not publish a segment or geography revenue split. What is documented is the customer and geography footprint the company itself claims, which stands in as the best available proxy for where its business actually sits.

• Sector spread, by the company’s own case-study list: a subsidiary of a Fortune 500 oil and gas company; one of Indonesia’s fastest-growing telecom operators; a Japanese consumer-electronics manufacturer; the world’s largest polystyrene-plastics manufacturer, by the company’s description; a US healthcare firm; and an Indian business-process-outsourcing centre (company resources page).
• Early pilot base was narrower still: as of January 2018, the only two named live deployments were an Indian media house and a financial exchange (TechBullion interview).
• Geographic incorporation: a registered entity in India (Mumbai/Thane) and in Singapore, with stated operations extending into the UK and the US, though no revenue is broken out by country.
• The surprise: despite four-country positioning and marquee-sounding case studies (Fortune 500 subsidiaries, a global electronics manufacturer), the only revenue actually filed anywhere in the public record — ₹2.62 crore for FY24 — is small enough that it is unlikely to represent more than a handful of active enterprise contracts at once. The global footprint in the marketing is real; the filed revenue suggests it is still a narrow, contract-by-contract business rather than a broadly diversified one.

The risks

• Scale versus category: Tracxn ranks Block Armour 174th among 471 active competitors it tracks in the same space, with Cisco, Zscaler and Wiz named as the top competitors — all companies with cybersecurity revenue and R&D budgets many orders of magnitude larger than Block Armour’s filed ₹2.62 crore. Competing for enterprise Zero Trust budgets against vendors that size is a structural, not a temporary, risk.
• Thin capitalisation and rising debt: paid-up equity capital of ₹10.53 lakh alongside a 267.89% year-on-year jump in borrowings (FY24, Tofler) point to a company increasingly reliant on debt rather than fresh equity to fund operations — a pattern that leaves less room to absorb a bad year.
• Distribution dependency: the company’s own listed go-to-market channels — Oracle Cloud Marketplace, Microsoft Azure Marketplace, India’s GeM portal, Schneider Electric Exchange, PwC’s marketplace — mean a large share of deal flow and margin runs through partners Block Armour does not control, rather than through a direct sales motion it owns.
• Key-person concentration: with one of three founding executives (Floyd DCosta) shown by Crunchbase to be simultaneously building separate ventures (Space Armour, Blockchain Worx) since at least mid-2023, and total headcount reported as low as 14 (Tracxn, August 2026), the company’s execution capacity sits with a very small group of people.

The takeaway

The lesson in Block Armour’s record is not about blockchain, or even about cybersecurity specifically — it is about the gap between being validated and being funded. A company can be picked from 150-plus applicants by Airbus, rated a market outperformer by an established analyst firm, and named among the world’s top cybersecurity innovations by one of the largest consultancies on the planet, and still be running on ₹10.53 lakh of paid-up capital and $53.2K of total disclosed outside funding the better part of a decade later. Awards travel faster, and further, than revenue. For a founder, the honest reading of Block Armour’s public record is that industry recognition is a distribution channel, not a substitute for one — it opens doors, as the Airbus relationship plainly did, but it does not by itself convert a two-pilot product into a scaled business. The two have to be built separately, and on this evidence, Block Armour has spent nine years working harder on the first than the public numbers show for the second.
