Gaby Cabezut is a bilingual literary agent and Director of Foreign Rights at The Seymour Agency who champions Latinx voices and commercial fiction across MG, YA, NA, and Adult, with a particular hunger for romance and an eye for global translation opportunities.
In brief
Her role has grown significantly: once an Assistant Agent focused on KidLit, she is now Director of Foreign Rights and a full agent acquiring across four market levels — MG through Adult — in both English and Spanish.
Romance is her stated expansion priority right now; writers with commercial romance projects in any of her target age categories are her most sought-after submissions.
She is NOT open to cold queries — submissions are by referral only as of her current agency page, which supersedes the earlier 'closed' notices and the 2025 illustrator-open social post.
Her foreign rights expertise and her leadership of The Seymour Agency Mexico make her unusually positioned to help authors break into Latin American markets — a real differentiator beyond standard representation.
Her public social presence signals continued interest in illustrators seeking representation, but her agency page defines the formal submission gate: referral only.
Lately
Announced openness to illustrators seeking representation, signaling continued investment in the visual side of KidLit even as her acquisitions focus has broadened.
What Gaby is looking for
This is her loudest stated priority right now. She wants commercial romance with bold, vivid characters whose voice or behavior leaps off the page. Classic, well-executed tropes — enemies-to-lovers, second-chance romance — are very welcome, so long as the execution feels fresh. She represents in both English and Spanish, so bilingual and Latinx-centered stories have a natural home here.
Commercial YA with a sharp, distinctive edge. She gravitates toward stories driven by strong character voice and propulsive pacing — the kind of narrative that earns a cliffhanger. Diversity and Latinx representation are recurring priorities across her list.
MG has been part of her focus since her earliest days at the agency and remains on her list. She values original voices, diversity, and stories with genuine emotional stakes for younger readers. Latinx perspectives are especially welcome.
Beyond romance, she is acquiring commercial fiction for the NA and Adult markets in both English and Spanish, with the same appetite for bold characters, unique angles, and stories that travel well across global markets.
Through The Seymour Agency Mexico she actively represents Latin American authors for the Spanish-language market. This is a distinct, underserved niche where her bilingual background and foreign rights expertise give her authors a concrete structural advantage.

How to query Gaby
A referral is required: cold queries will not be considered under current guidelines. Network at conferences, through mutual author contacts, or through The Seymour Agency's existing client community to obtain one.
She represents in both English and Spanish — if your project has strong Latin American market potential or you are a Latinx author, lead with that angle; it is central to her identity and her foreign rights mandate.
Romance writers should position their project as commercially driven and trope-aware. She enjoys familiar romance structures, but the execution must feel distinctive — name the trope, then explain the fresh twist.
Avoid pitching high fantasy or horror; she has explicitly named both as outside her list regardless of how well-crafted the project is.
Her background is digital and tech-fluent; a polished, professional online presence for your author brand is likely noticed and valued.
A cliffhanger-driven, fast-paced narrative structure is a recurring theme in her stated taste — if your manuscript has propulsive plotting, that is worth mentioning in the query letter.
She actively noted interest in illustrators via social media; if you are seeking representation as an illustrator, that signal is worth following up on through her agency's contact channels.
