The issue is most likely that make-forkexec-constructor's COMMAND
argument expects a list of strings [0]. Try and see if this works:

#+BEGIN_SRC scheme
(service home-shepherd-service-type
                 (home-shepherd-configuration
                  (services (list
                             (shepherd-service
                              (provision '(syncthing))
                              (start #~(make-forkexec-constructor
                                        (list "syncthing") #:user #:t))
                              (stop #~(make-kill-destructor))
                              (documentation
                               "Synchronize folders to other=20
                               device"))
                             (shepherd-service
                              (provision '(pantalaimon))
                              (start #~(make-forkexec-constructor
                                        (list "pantalaimon") #:user #:t))
                              (stop #~(make-kill-destructor))
                              (documentation
                               "Crypto back-end server for=20
                               ement.el"))))))
