In March, Apple informed the European Commission that it had agreed to acquire certain assets and hire employees from SigScalr, according to a notice published today on the commission's website.

SigScalr created the open-source observability platform SigLens, which companies use to aggregate and analyze logs, metrics, and traces at massive scales for monitoring and debugging. SigLens was known for being a cost-effective and fast solution compared to many competing platforms.

The acquisition follows a similar pattern to Apple's February notification regarding assets from Rabbit 3 Times, the company behind the design tool Play. These moves suggest Apple is quietly expanding its engineering talent and technology portfolio through targeted asset purchases.
