+### How does my quota work during my ramp period
+
+Your first 3 months commission is guaranteed. This will be calculated based on the date you start. If you start before the 15th of a month you will get guaranteeed commission for that month and all the remaining months in the quarter eg. If you start on the 13th January you will get guaranteed commission for Jan, Feb & March. If you start on the 17th Jan, you would get two months guaranteed commission. 
+
+The number of months of guaranteed commission in your first quarter will correlate to the size of your quota in your second quarter. If you receive three months of guaranteed commission in your first quarter you will be on full quota for your second quarter. If you receive two months, you will be on two thirds of your ramped quota; if you receive one month, you will be on one third of your rammped quota. 
+
+You will always be on full quota by your third quarter - unless you start after the 15th in the last month of a quarter, in which case for quota purposes & guaranteed commission it will be like you started on the 1st of the new quarter.

 ### How does support work at PostHog?
 
 - Generally, you're expected to be able to be the first line of support for customers at PostHog. You should be able to answer _most_ yourself - that's why we hire _Technical_ AEs and AMs after all! #ask-max in Slack can often help too.
