              After reviewing any amendment to your registration statement and

       Form F-1 filed on May 25, 2021

       Prospectus Summary, page 1

   1.                                                   We note your revised
disclosures in response to prior comment 3 where you discuss the
                                                        growth in both Video
and CTV revenue for the six months ended June 30, 2020 compared
                                                        to the six months ended
December 31, 2020. As CTV revenue is a subset of Total Video
                                                        revenue, please revise
to indicate as such and to discuss the increase in Total Video
                                                        revenue separately from
CTV revenue for each half of fiscal 2020. Similar revisions
                                                        should be made
elsewhere where you include these disclosures.

2.       Please revise to clearly state that beginning in fiscal 2020 you
determined that you
         operated as an agent with respect to your Programmatic activity and
therefore present
         revenue on a net basis. Also, we note your disclosures on page ii
where you state "[i]n
         order to improve comparability and provide a more meaningful basis for
comparison of
         our financial results, this prospectus includes certain unaudited, as
adjusted (non-IFRS)
         revenue information solely for the year ended December 31, 2019 that
give effect to the
         revenue recognition changes noted above as if such changes were
applied on January 1,
         2019. This as adjusted (non-IFRS) revenue information will not be
provided for any
         period subsequent to the year ended December 31, 2019." Please revise
to include similar
         language in the introductory paragraph to the reconciliation table on
page 63.
Key Operating Metrics, page 79

3.       We note your measure of "average contribution ex-TAC per active
customer." Please tell
         us what is meant by "average" contribution or revise as necessary.
Also, revise to include
         the comparable IFRS measure of gross profit per active customer here
and wherever else
         you discuss this measure. Refer to Question 102.10 of the non-GAAP
4.       Please revise your reference to "net revenue retention rate" in the
table to refer to the
         correct measure of contribution ex-TAC retention rate.
Business, page 84

5.       We note your revised disclosures in response to comment 1. Please tell
us the actual
         number of publishers at March 31, 2021. Also, revise to include the
actual active
         publisher count in this filing for each period presented. In this
regard, while you state in
         your response to comment 3 in your April 13, 2021 letter that you
believe providing an
         approximate figure is more appropriate since this number can fluctuate
over time,
         considering you rely on publishers in order to conduct your business,
it would seem that
         the actual publisher count is important to an understanding of your

6.       We note your disclosure that the deposit agreement includes a waiver
of jury trial
         provision and an exclusive forum provision. Please include a risk
factor addressing the
         impact of these provisions of this deposit agreement on the rights of
ADS holders.
