Son of the silversmith Francesc Cabot, he followed in the family tradition and contributed innovations in the Modernista style typical of his time before eventually going on to introduce the trends of the new Noucentista ("1900-ist", a term coined in 1906 to refer to 20th century Catalan culture) current. In 1905 he opened a jewellery shop in Barcelona that acquired great prestige before being sold to the Madrid-based Casa Sanz.

The field in which he was most successful was the social life of the city. He was chairperson of various public sector companies, the Barcelona Trade Fair, the Rambling Centre of Catalonia and the Orfeó Català choral society between 1901 and 1935, when the Palau de la Música Catalana (Palau de la Música, 4-6) was built.

He wrote articles on art criticism in La Renaixença under the nom de plume of "Dr. Franch" and was the editor of the daily newspaper La Veu de Catalunya which he founded in 1899. He wrote a column for this paper called "Notes Artístiques" ("Artistic Notes") in which he was not a great champion of Modernista artists.

He commissioned the architect J. Vilaseca to build Cases Cabot (1901-1904 ; Roger de Llúria, 8-10, 12-14,).

He was actively involved in Catalan politics as a provincial deputy in 1911 and participated in the setting up of the Mancomunitat de Catalunya, a body bringing together Catalonia's four provincial councils.
