Isar Aerospace launch into orbit [video]

How does Isar Aerospace fit in with other smaller rocket launchers?

I'd imagine they are well behind, say, RKLB, but how far are they from commercial launches?

Edit after some digging, some background info:

   Vehicle   | Height | Diameter | Payload to LEO
  -----------+--------+----------+----------------
   Electron  |  18 m  |   1.8 m  |      300 kg
   Isar      |  28 m  |   2.0 m  |     1000 kg
   Neutron * |  43 m  |   7.0 m  |    13000 kg
   Falcon 9  |  70 m  |   3.7 m  |    23000 kg

  * in the works

As a person involved in the operations side of this campaign. HOLY SHIT we did it!
