Ignoring big old companies like Airbus, Thales Alenia, SES, etc, there are a handful of smaller companies I'm following a bit.
The Exploration Company is working on a space station cargo capsule that can be upgraded for crew. D-Orbit keeps launching space tugs. ICEYE seems to be doing well with their SAR constellation. Exotrail sells smallsat prop systems and has a tug.
For launch, PLD, RFA, and Isar, (and a lot of smaller ones) are racing to operations.
There are also a handful of companies with locations in the US and Europe, like Loft, Oneweb, and Redwire.
