Abriendo la Red

En 2009 abrimos la red, haciendo posible que cualquiera con un receptor ADS-B contribuyera datos. Este fue el punto de inflexión: entusiastas de la aviación en todo el mundo comenzaron a unirse.

How Mikael actually did it

5/7 funnel stages sourced

Reconstructed from Mikael's own published sources. Quoted claims are the founder's words, verified verbatim; anything marked as our analysis is exactly that.

Where the idea came from

Side project spinoutPivot from A Swedish flight price comparison service the founders were running; the tracker began as an SEO side project for it, moved to its own domain in 2009, and was split into a separate company in 2012.

Flightradar24 was not started as a product. The two founders were already running a Swedish flight price comparison service, and the flight tracking page was built as a search engine optimisation project to pull links back to that service. It outgrew its parent, and in 2009 it was moved onto its own domain as a separate service.

“this was like an easier search engine optimization project to get more links to this price comparison service”

Mikael Robertsson on AvTalk Episode 20, "A Look Inside Flightradar24" (Flightradar24's own podcast; transcript published by Flightradar24 on its own domain)

Validation

Built first, validated after

MvpValidated

The founders installed two ADS-B receivers in Stockholm in 2006 and published screenshots from the first receiver on a webpage. There was no test audience and no pre-launch signal collection: the page itself was the test. It spread quickly and strangers in Europe and Scandinavia wrote in to ask how it was done, which is the first evidence in the founder's account that the tracker mattered on its own.

The webpage of receiver screenshots became popular fast and produced unsolicited inbound questions from other enthusiasts.

“it’s got popular very fast and people from Europe and Scandinavia started to contact us”

Mikael Robertsson on AvTalk Episode 20, "A Look Inside Flightradar24" (Flightradar24's own podcast; transcript published by Flightradar24 on its own domain)

First test users

Content readersFree testers

The first users found a plain webpage showing screenshots from the founders' first ADS-B receiver, published alongside the price comparison business they already ran. Nothing in the founder's account describes any promotion of that page.

“we put the screenshots from the SBS1 as the first receiver was called on a webpage”

Mikael Robertsson on AvTalk Episode 20, "A Look Inside Flightradar24" (Flightradar24's own podcast; transcript published by Flightradar24 on its own domain)

Acquisition channels, and whether they worked

SEO / ContentPre-launchWorked

The flight tracking page existed to generate inbound links to the founders' Swedish price comparison service.

“this was like an easier search engine optimization project to get more links to this price comparison service”

Mikael Robertsson on AvTalk Episode 20, "A Look Inside Flightradar24" (Flightradar24's own podcast; transcript published by Flightradar24 on its own domain)

Word of MouthPre-launchWorked

Aviation enthusiasts who had seen the screenshot page contacted the founders to ask how it worked, and the founders answered by shipping them receivers, first in Sweden, then Norway and Poland.

“we started to send out receivers to initially Sweden, later Norway and then Poland”

Mikael Robertsson on AvTalk Episode 20, "A Look Inside Flightradar24" (Flightradar24's own podcast; transcript published by Flightradar24 on its own domain)

Other · Earned media during the Eyjafjallajökull ash cloud, April 2010ScalingWorked

TV stations used the Flightradar24 map to show European airspace emptying during the volcanic ash shutdown. The founders did no outreach for it.

“in April 2010 we had the Icelandic ash cloud, and that was the first time that we got media coverage”

Mikael Robertsson on AvTalk Episode 20, "A Look Inside Flightradar24" (Flightradar24's own podcast; transcript published by Flightradar24 on its own domain)

Word of MouthScalingWorked

The media wave converted into supply rather than only traffic: people worldwide wrote in either to run the data sharing software themselves or to be sent a free receiver.

“After the media coverage, there was a lot of people from all around the world contacting us”

Mikael Robertsson on AvTalk Episode 20, "A Look Inside Flightradar24" (Flightradar24's own podcast; transcript published by Flightradar24 on its own domain)

How it changed as they grew

At launch: 2 people (Mikael Robertsson and Olov Lindberg, alongside the price comparison business they were already running)

What broke as they grew

At the moment of breakthrough the binding constraint was serving capacity, not demand. Around 4 million people arrived in one day during the April 2010 ash cloud, and by his own account the infrastructure of the time could not have rendered a normal sky for them. The empty airspace is what made the spike survivable.

“we had quite bad server capacity back then”

Mikael Robertsson on AvTalk Episode 20, "A Look Inside Flightradar24" (Flightradar24's own podcast; transcript published by Flightradar24 on its own domain)
