On the other hand, the staff has been increased considerably, which will have some impact on the burn rate.

On the other hand again, the new staff will not sit around, twiddle their thumbs and wait for their wages. Okay, some of them might work on projects that will bear fruit in the future only and thus are only a "cost factor" at the moment. However, others are working on actual customer projects that will likely be paid for on the near term or even partly in advance. This will also have some impact on the burn rate.

We don't know what the net effect is, but the Q3 report should shed some light.
