The core timescaledb repo [0] currently has 10-15 primary engineers, with a few others working on DB hyperfunctions and our function pipelining [1] in a separate extension [2]. I think generally the set of outside folks who contribute to low-level database internals in C is just smaller than other type of projects.
We also have our promscale product [3], which is our observability backend powered by SQL & TimescaleDB.
And then there is Timescale Cloud [4], which is obviously a large engineering effort, most of which does not happen in public repos.
Interested? We're growing the teams aggressively! Fully remote & global.

It looks like there has only really been 7-10 full time contributors and for you to have raised what you have with such a small team is quite impressive. Is development happening elsewhere or is my hunch correct?
Edit: Thanks to feedback from mfreed, below is a more accurate picture of development activity:
