       Amendment No. 1 to Draft Registration Statement on Form S-1

       Risks Related to Ownership of our Class A Common Stock
       Our listing differs significantly from an underwritten initial public
offering, page 42

   1.                                                   Please replace the
first two sentences of this risk factor with the sentence: "Prior to the
                                                        opening of trading on
the Nasdaq Select Global Market, there will be no book building
                                                        process and no price at
which underwriters initially sell shares to the public..." in order to
                                                        properly focus the risk
on the underwriting activities that will not be present.
       Capitalization, page 62

   2.                                                   The capitalization
table discloses that there are no preferred shares authorized, issued, and

         outstanding on an actual basis as of June 30, 2021. As the Existing
Preferred Stock
         Conversion is included as an adjustment for the pro forma
capitalization disclosures,
         please revise to disclose the actual preferred share information as of
June 30, 2021.
Management's Discussion and Analysis for Financial Conditions and Results of
Operations
Key Business Metrics, page 67

3.       We note the revised disclosure in response to prior comment 1. Please
explain to us why
         you believe disclosing the dollar-based net retention rate for
customers with ARR greater
         than $100,000 would not provide material additional information to
investors. In this
         regard, we note the significance of customers with greater than
$100,000 ARR as a
         percentage of total ARR and the significant difference between the
previously disclosed
         dollar-based net retention rate for such customers compared to total
paying customers as
         of December 31, 2020. In your response, please tell us the
dollar-based net retention rate
         for customers with greater than $100,000 ARR as of December 31, 2019
and June 30,
         2021.
Description of Capital Stock
Equity Award Amendment, page 162

4.       Your revised disclosure states that the holders of Class A common
stock, which was
         received as a result of the Equity Award Amendment, will have the
right to exchange on
         one occasion such shares for Class B common stock. Please revise to
clarify what is
         meant by "on one occasion." Ensure your disclosures address whether
this refers to a pre-
         defined time period as well as any other restrictions related to the
holders right to
         exchange aside from until such time as the Class A shares are
transferred. Also, please
         clarify whether a holder can choose to exchange only a portion of the
Class A common
         stock and if so, whether that will impact their ability to exchange
any remaining Class A
         shares. Lastly, disclose whether the right to exchange the Class A
shares is conveyed if the
         Class A common stock is transferred to a permitted transferee.
Plan of Distribution, page 175

5.       Please disclose which specific Nasdaq rule provision requires Nasdaq
to consult with
         Morgan Stanley and the other financial advisors when conducting its
price validation
         checks and clarify the type of guidance Nasdaq may seek from Morgan
Stanley and the
         other financial advisors when conducting its price validation checks
on the day of listing.
Note 5. Stockholder's Deficit and Equity Incentive Plans, page F-20

6.       We note that during 2019 and 2020 you facilitated secondary
transactions with select
         executives in which common stock was sold above fair value. In
addition, we note
         that you removed disclosure on pages 153 and 154 regarding certain
Stock
         Transfer Agreements in fiscal 2019 and December 2020. With regards to
each of the
         secondary transactions for which you recorded compensation expense
during fiscal 2019
 Spenser Skates
Amplitude, Inc.
August 9, 2021
Page 3
      and 2020, including any such transactions to date in fiscal 2021, please
describe for us the
      extent of your involvement in such sales. Also, tell us whether you
helped arrange the
      transaction, whether the secondary transaction was concurrent with or a
condition to a sale
      of other financial instruments by the company to the third party, how the
per share
      purchase price was determined, the amount of compensation expense related
to the
      transaction, and whether the third party purchaser had a pre-existing
economic interest in
      the company at the time of the secondary transaction.
Restricted Stock Units, page F-24

7.    Your revised disclosure in response to prior comment 17 states that the
liquidity event
      includes a change in control or an initial public offering of the
company's securities.
      Please revise to clarify what is meant by "the initial public offering"
for purposes of
      satisfying the performance condition for your restricted stock units.
Also, ensure
      you address whether a direct listing the company's Class A common stock
meets the
      definition of an initial public offering for vesting purposes.
Consolidated Financial Statements
Note 11. Subsequent Events, page F-30

8.    We note from your response to prior comment 18 that you intend to include
stock-
      based awards granted during the six months ended June 30, 2021 in your
interim period
      financial statements when provided. To the extent you grant additional
awards after such
      date, please ensure you disclose those grants and the expected financial
impact in your
      subsequent event footnote, if material. In this regard, it is unclear how
you assessed the
      significance of unrecognized compensation expense on future periods for
the grants
      addressed in your response. In your response, please provide us with the
aggregate grant
      date fair value and unrecognized stock-based compensation expense for all
      awards granted subsequent to June 30, 2021. Refer to ASC 855-10-50-2.
