$1M ARR in 17 days, $0 a month by 2026: the flight sim that ran out of runway

Pieter Levels built a browser flight simulator in about three hours, sold virtual jets and billboard space inside it, and tweeted "$0 to $1M ARR in 17 days." Two details the tweet left for later: the money was one-off purchases rather than anything recurring, and Levels himself wrote he could "only guess" whether it would hold. By mid-2026 his own public bio listed the flight sim at $0/month. Both numbers have receipts. The question is whether the first one was ever ARR.

fly.pieter.com has now gone from $0 to $1 million ARR in just 17 days! Revenue update: $87,000 MRR (which is $1M ARR) My first project ever to go up this fast

The claim that fly.pieter.com reached $1M ARR in 17 days is partially contradicted by evidence suggesting that the MRR might not have been sustainable and that the project's revenue dropped to $0/m by mid-2026. The use of ARR for non-recurring revenue is also questionable. The base rate indicates that such rapid growth is highly unusual. The interested party cap applies, as the primary support comes from Pieter Levels' own account.

  • dev.to: “In the same post he wrote, 'Whether the MRR is truly sustainable for a year we can only guess.' He flagged the risk himself, in the victory tweet.”
  • dev.to: “Here is the number the headlines never followed up on. As of his live X bio in mid-2026, the flight sim line reads 'Pieter.com $0/m.'”

What would change this

  • Independent verification of the revenue figures and sustainability of the MRR over time.
