   1.                                                   We note your measure of
free cash flow includes an adjustment for direct listing expenses
                                                        paid. Please remove
this adjustment as charges that require cash settlement cannot be
                                                        excluded from non-GAAP

2.       We note your letter dated August 13, 2021 and we request additional
analysis supporting
         the significant increase in the estimated fair value of your common
stock from December
         2020 to June 2021. Please quantify and describe the extent to which
each of the factors
         that you list impacted each valuation and support the fluctuations in
your common stock
         valuation between each of the valuations from December 2020 to the
most recent. To the
         extent that increases in your valuations were not solely attributable
to changes in your
         financial condition or results of operations, quantify and describe
how these other factors,
         such as company-specific or industry events, changes in valuation
methodology or
         significant assumptions impacted each valuation.
3.       Please tell us the fair value of the underlying common stock at each
option grant date from
         December 2020 to now. Also, explain how you utilized a linear
interpolation between the
         valuation dates. In this regard, your explanation at each valuation
date implies that the
         fair value of your common stock at each grant date was equal to the
most recent valuation
         before such grant.

4.       We note your response to prior comment 5; however, the added
disclosure does not clarify
         in Plain English what the price validation test entails. Please
clarify.

5.       We note from your response to prior comment 8 that you are currently
unable to estimate
         unrecognized stock-based compensation expense for the grants made
subsequent to the
         most recent balance sheet date, please revise your disclosures to
indicate as such. Refer to
         ASC 855-10-50-2(b).

6.       Please revise the graphics in the forepart of the registration
statement to present a
         balanced picture of the company's financial health. In this regard, we
note that you had a
         net loss for each period presented and indication of such should be
given equal
         prominence with your current presentation, which emphasizes revenue
growth and 12-
         month trailing revenue information. Refer to Securities Act Forms C&DI
101.02.
