SendWise Set a New Record: $124K for a $6.2K MRR API Business

SendWise, a transactional email API for developers, just closed at $124,000 — a 20x MRR multiple that set a new platform record. The auction was a masterclass in what happens when a great product meets competitive bidding.

The numbers tell the story: 67 bids from 12 verified bidders over 24 hours, with a peak of 489 simultaneous spectators. The anti-snipe extension triggered 7 times in the final hour, adding 35 minutes to the auction.

SendWise had everything buyers look for: $6,200 in monthly recurring revenue with sub-1% churn, a developer-friendly API with clean documentation, and 340+ paying customers with no single customer exceeding 2% of revenue.

The auction opened at $45,000 and hit $80,000 within four hours. The midday lull saw only 3 bids in a 6-hour window. Then the final push began: starting at 6 PM, bids came in rapid succession as three serious buyers competed for the win.

The final 30 minutes were electric. Anti-snipe extensions kept pushing the deadline as bids climbed from $108K to the final $124K. The winning bidder — anonymously known as Bidder #7 throughout the auction — placed 14 bids total.

For the seller, the outcome exceeded expectations. They had initially considered listing on a traditional marketplace at an asking price of $90K. The auction format delivered 38% more than their own optimistic estimate.
