Apple acquired parts of the US startup SigScalr on March 12th. The deal only became public now, four months later, and not through Apple itself, but via a database of the EU Commission. Without the reporting requirements from Brussels, no one would know about it.

Apple regularly acquires small companies and remains silent about it – the company traditionally only confirms such acquisitions upon request and with a standard statement. This time, the path to public disclosure leads via a circuitous route that Apple is unlikely to appreciate: through the Digital Markets Act. Just last week, the company lost its attempt before the EU court to shed its gatekeeper status. This very status now obligates Apple to report every acquisition in Brussels – where it ends up on a publicly accessible list.

What SigLens can do

SigScalr is the company behind SigLens, an open-source observability platform. The term sounds more cumbersome than it actually is: Large software systems constantly produce data trails during operation – logs, measurements, and so-called traces that map the path of a request through the infrastructure. Observability tools collect these traces, make them searchable, and help to find errors and bottlenecks before users notice them.

SigScalr has explicitly positioned SigLens as a leaner and more efficient alternative to the established industry heavyweights – Splunk, Datadog, and Elasticsearch. Given the scale of systems Apple operates, the difference between an efficient and a wasteful tool quickly becomes a matter of server costs in the millions.

The deal only became known through Brussels

The Digital Markets Act requires companies classified as gatekeepers – besides Apple, these include Alphabet, Amazon, ByteDance, Meta, and Microsoft – to notify the European Commission of acquisitions. The Commission then publishes these notifications on a dedicated website. SigScalr has now appeared there.

Apple's description to the Commission is remarkably matter-of-fact: It will acquire certain assets of SigScalr through a subsidiary and offer employment to some of the company's employees. SigScalr develops a tool for log management and observability. This is not a classic company takeover, but rather the industry-standard mix of technology and personnel acquisition.

The list indicates the transaction date as March 12, 2026. Apple remained silent for four months – and would likely have continued to do so. The very existence of this information is a direct consequence of the regulation the company recently and unsuccessfully challenged in Luxembourg.

The traces on the internet have already disappeared

Anyone wanting to trace the process will find the usual signs. The SigScalr website is now offline. The central SigLens GitHub repository has been archived and set to read-only access.

At least the developers didn't simply shut down the project: they switched the license to Apache 2.0 as a farewell gesture, a significantly more permissive version. This means the code remains available, and anyone is free to fork and further develop it. In their farewell message, they thanked the community and wrote that they were now dedicating themselves to something new – what that is should be clear, especially since the EU announcement.

Why does Apple need such a tool?

Apple has not commented on the purpose of the acquisition, and speculation is no substitute for confirmation. However, the timing can be seen in an obvious context: With iCloud, the App Store, and its own services, Apple already operates one of the largest infrastructures in the industry – and is currently expanding it massively. Apple Intelligence queries are routed through Private Cloud Compute, which now partially relies on Google infrastructure. The more distributed these systems become, the more important tools are that can expose flaws within them.

This acquisition is the latest in a series of smaller purchases. At the end of June, Apple acquired the design tool Play, and in May, the creators of Color.io for its Creator Studio. The company rarely makes spectacular purchases, but its acquisitions are steady.

The DMA makes Apple's silent acquisitions visible

For users in Germany, Austria, and the EU, this development has a side effect that extends beyond the actual news. While the Digital Markets Act is usually discussed in terms of sideloading, alternative app marketplaces, and missing features, here a different effect becomes apparent: it creates transparency about processes that Apple would have preferred to keep private. This does not apply to Switzerland, however; as a non-EU country, it is not subject to the DMA obligations.

Whether this acquisition will ultimately result in a tangible product or simply speed up the machinery behind the scenes remains to be seen. The more interesting insight, however, lies on a meta-level: Apple can no longer conceal its acquisitions as long as it is considered the gatekeeper in Europe – and this remained unchanged in court last week.
