to comment 1, and your amended disclosure that you are "one of"

3.       We note your response to our prior comment 18, and reissue the comment
in part. Please
         tell us why you believe that the average retention rate provides
investors with information
         necessary to understand the retention rate and its overall impact on
your business, and
         how presenting the average for each year in a five-year period is
appropriate given that
         2015 appears to be the only cohort which is included in each of the
years. In the
         alternative, please break out the data separately for each cohort.

4.       We note your response to comment 20, and your amended disclosure on
page 72.
         However, your disclosure provides increasing value for the Registrant
 s LTV/BAC ratio
         for each year in solely the 2017 cohort's life, and provides no data
for other cohorts with
         respect to the LTV/BAC ratio. To provide investors with context
regarding how your
         LTV to BAC ratio is "increasing," please amend your disclosure to
provide LTV to BAC
         data for other cohorts before and after 2017. Please also tell us how
you allocate retention
         marketing costs in a single year, including performance-based
marketing, among the
         various cohorts.

Cash Flows
Cash Flows from Operating Activities, page 84

5.     Your discussion of cash flows from operating activities appears to focus
on how this
       amount was derived in each period. The discussion should be a
comparative analysis of
       material changes in this amount between periods. Refer to Item 303(a)
and (b) of
       Regulation S-K. In your analysis, please note that references to results
of operations,
       which is prepared on the accrual basis of accounting, and working
capital movements may
       not provide a sufficient basis for an investor to fully understand
comparative changes in
       terms of cash. Refer to Section IV.B.1 of    Interpretation: Commission
Guidance
       Regarding Management's Discussion and Analysis of Financial Condition
and Results of
       Operations    for guidance. Your discussion should address the drivers
underlying each

6.       We note your response to comment 18, including that the chart on page
69 represents
         retention rate for seller cohorts, and the statement on page 94
relates to on-platform GMV
         from buyers. To provide context for investors related to your buyer
retention, please
         amend your disclosure in this section to provide your buyer GMV
retention rate for 2019.
         As a related matter, please clarify how you attribute GMV to specific
buyers or buyer
         cohorts, including how you define buyer cohorts, considering that you
define GMV as
         "the total dollar value from items sold by our sellers through 1stDibs
in a given month,
         minus cancellations within that month, and excluding shipping and
sales taxes" (emphasis
         added).
