Item 1.	Security and Issuer
             The security to which this statement relates is the common stock,
0.001 par value (the Common Stock), of Synlogic, Inc. (the Issuer), whose
principal executive offices are located at 301 Binney St. #402, Cambridge, MA
02142.
Item 2.	Identity and Background
             (a)	This statement is being filed by Funicular Funds, LP (the
Fund), a Delaware limited partnership, with respect to the Common Stock
beneficially owned and held of record by the Fund. The General Partner of the
Fund is Cable Car Capital LLC (Cable Car), a California limited liability
company which serves as investment adviser to the Fund pursuant to a written
advisory agreement. Jacob Ma-Weaver, a United States citizen, is the Managing
Member of Cable Car and the ultimate individual responsible for directing the
voting and disposition of Common Stock held by the Fund.
             Each of the Fund and Mr. Ma-Weaver are referred to as a Reporting
 Person and collectively as the Reporting Persons.
             (b)	The principal business address for the Reporting Persons is
601 California Street, Suite 1151, San Francisco, California 94108.
             (c)	The Fund is a private investment partnership whose principal
 business is investing and trading in securities. Cable Car is an investment
adviser registered with the state securities authority of California. Its
principal business is investment management. Mr. Ma-Weaver has sole
discretionary authority over the accounts of the Fund.
             (d)	During the last five years, none of the Reporting Persons has
been convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors).
             (e)	During the last five years, none of the Reporting Persons has
been a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction and as a result of such proceeding been subject to a
judgment, decree or final order enjoining future violations of, or prohibiting
or mandating activities subject to, federal or state securities laws or finding
 any violation with respect to such laws.
Item 3.	Source and Amount of Funds or Other Considerations
             The Common Stock to which this Schedule 13D relates was acquired
for an aggregate purchase price of $5,446,149.05, inclusive of brokerage
commissions and fees.  Funds for the purchase were obtained from the available
working capital of the Fund.  Although the Fund has the ability to obtain
margin loans in the ordinary course of its business, no part of the purchase
price was obtained on margin or through any other borrowings.
Item 4.	Purpose of Transaction
             The Reporting Persons wish to express condolences on the recent
disappointing clinical outcome while commending the Board of Directors on its
swift response. The Reporting Persons intend to provide input into the
announced strategic alternatives review process.
             The Reporting Persons purchased the Shares based on the Reporting
Persons belief that the Shares, when purchased, were undervalued and
represented an attractive investment opportunity. Depending upon overall market
 conditions, other investment opportunities available to the Reporting Persons,
 and the availability of Shares at prices that would make the purchase or sale
of Shares desirable, the Reporting Persons may endeavor to increase or decrease
 their position in the Issuer through, among other things, the purchase or sale
 of Shares on the open market or in private transactions or otherwise, on such
terms and at such times as the Reporting Persons may deem advisable.
             No Reporting Person has any present plan or proposal which would
relate to or result in any of the matters set forth in subparagraphs (a) - (j)
of Item 4 of Schedule 13D except as set forth herein or such as would occur
upon or in connection with completion of, or following, any of the actions
discussed herein. The Reporting Persons intend to review their investment in
the Issuer on a continuing basis. Depending on various factors including,
without limitation, the Issuers financial position and investment strategy,
the price levels of the Shares, conditions in the securities markets and
general economic and industry conditions, the Reporting Persons may in the
future take such actions with respect to their investment in the Issuer as they
 deem appropriate including, without limitation, engaging in communications
with management and the Board of Directors of the Issuer, engaging in
discussions with stockholders of the Issuer or other third parties about the
Issuer and the Reporting Persons investment, including potential business
combinations or dispositions involving the Issuer or certain of its businesses,
 making recommendations or proposals to the Issuer concerning changes to the
capitalization, ownership structure, board structure (including board
composition), potential business combinations or dispositions involving the
Issuer or certain of its businesses, or suggestions for improving the Issuers
 financial and/or operational performance, purchasing additional Shares,
selling some or all of their Shares, engaging in short selling of or any
hedging or similar transaction with respect to the Shares, including swaps and
 other derivative instruments, or changing their intention with respect to any
and all matters referred to in Item 4.
Item 5.	Interest in Securities of the Issuer
             The aggregate percentage of Shares reported owned by the Reporting
 Persons is based on 9,189,353 shares outstanding as of November 2, 2023, which
 is the total number of shares outstanding as reported in the Issuers
Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission
 on November 9, 2023.
             As of the close of business on February 16, 2023, the Fund
beneficially owned 3,312,219 Shares, constituting approximately 36.0% of the
Issuers outstanding Shares. Cable Car, as the general partner of the Fund, may
 be deemed the beneficial owner of the 3,312,219 Shares owned by the Fund. Mr.
Ma-Weaver, as the Managing Member of Cable Car, may be deemed the beneficial
owner of the 3,312,219 Shares owned by the Fund.
Item 6.	Contracts, Arrangements, Understandings or Relationships with Respect
to Securities of the Issuer
             There are no contracts, arrangements, understandings, or
relationships between the Reporting Persons and any other person with respect
to the securities of the Issuer.
Item 7.	Material to Be Filed as Exhibits
             Exhibit A. Joint Filing Agreement
