Why we fly magnetometers, not cameras: the specialisation thesis behind Flybi

Most drone services companies in India have the same pitch: “We fly anything. Aerial survey, inspection, mapping, you name it.” For a growing firm, that’s comforting — it keeps the pipeline broad. For a buyer, it’s useless. A generic capability pitch cannot win a tender against three other generic capability pitches, and commodity pricing is what follows.

By late 2024, we had already run enough engagements in mining and geological mapping to notice something we’d been writing off as a quirk. The jobs where we delivered real client value — and where we could defend our price — were almost always the ones involving magnetometer payloads. Specifically, ones where the client wanted not just “the data” but interpreted outputs: which anomalies to drill, which corridors to avoid, where the pipeline buried in the 1970s actually runs.

The jobs where we were a commodity were the ones where the client wanted a photographer with rotors. Those margins were thinner every quarter.

So we did the uncomfortable thing a services firm is rarely willing to do: we picked a vertical and said out loud, to ourselves and then to clients, that we were a magnetometer-led firm. Everything else — mapping, inspection, air quality — would remain capabilities. But the brand, the landing pages, the pitch deck, and the senior-hiring plan would now all converge on one question: Are we the best airborne magnetometer team operating in difficult terrain across India, East Africa, and emerging Latin American markets?

Why magnetometer, specifically

Three reasons. None of them are “because it’s interesting.”

One — the compression is real. A ground magnetometer survey over a 50 km² block is a 4-to-8 week undertaking. It involves foot crews in terrain that is often difficult and sometimes hostile — dense forests, tailings slopes, mine-affected areas, border-adjacent blocks. Every day the crew is in the field costs money and creates risk. Airborne acquisition over the same grid, flown at survey spec, completes in 4–6 field days. The interpretation adds 3–4 days on top. The whole compression is roughly 12 working days, end-to-end, against the 30–60 days the ground alternative needs. This is not a marketing round-up; it is what we have measured across our recent airborne magnetometer engagements.

Two — the interpretation layer is a moat. Anyone with a drone and a rented payload can fly lines. What they cannot easily do is stand up a small team of trained geologists who can look at the processed grid, identify which anomalies are drill-worthy, and produce a handover report a mining company’s exploration lead can bring into their weekly meeting. We built that team deliberately — not as a consulting line, but as the core of the service. Our clients don’t buy raw SEGY files from us. They buy the interpreted anomaly map.

Three — the market is globalising in our favour. East Africa’s mineral exploration economy is early, and the countries that matter — Uganda, Kenya, Tanzania — do not have incumbent airborne geophysics providers flying regularly. Latin America is similar in the smaller exploration markets. The first real acquisition platform a government ministry engages with in those contexts tends to become the long-term partner. That is the window we are moving through.

What specialisation has actually cost us

Two things, both worth stating. First, we have turned down a growing share of general drone work year-on-year. Some of that was wedding videos and corporate farms we were never going to enjoy. Some of it was inspection contracts we could have technically won. We are accepting the trade.

Second, the website, the deck, and the signature — every inbound-facing touchpoint — had to be rebuilt. A firm that says it specialises in magnetometer can’t have a home page that leads with a stock photo of a quadcopter over a paddy field. This is the exercise we are in the middle of now, and it is as much editing as it is writing. A great deal of content exists that was true in 2024 but is no longer a faithful representation of what we want to sell.

What this means for a prospective client

If you are a mining exploration lead, a procurement head at a power utility, or an infrastructure operations manager looking at subsurface integrity, this is the shortest version of our pitch: we will give you a calibrated airborne magnetometer acquisition and an interpreted anomaly map for roughly a third of the ground survey clock, and our price is benchmarked against the total cost of the ground alternative — including crew mobilisation, accommodation, risk premia — not against a per-hectare drone rate card.
