Ask HN: What platforms have the fastest 3rd party app approval process?

I built an Airtable app and it took 3-4 months from the time I submitted until it was approved and live on the site. Slack was faster (only a few weeks IIRC) and Procore took a couple months as well.

What platforms (preferably fast growing ones), have you been pleasantly surprised about how fast they work with small partners?
