Introduction
Nabla is a clinical AI company co-founded in 2018 by Alexandre LeBrun, operating across Paris and New York according to its about page. The company builds ambient documentation tools that let clinicians stay present during encounters while AI drafts structured notes and patient instructions. LeBrun’s background includes selling AI startups to Nuance and Facebook before pivoting to healthcare — a founder narrative Nabla discusses openly in its blog as motivation for tackling documentation burden rather than consumer chatbots.
Nabla’s May 28, 2026 customer story with Catalight, a behavioral-health organization serving children and families, illustrates deployment beyond hospital medicine into emotionally complex visits where eye contact and empathy matter as much as note completeness.
Nabla’s about-us page lists Alexandre LeBrun as co-founder alongside Delphine Groll and Martin Raison — leadership continuity health systems consider when signing multi-year ambient contracts.

What the company does
Nabla provides an ambient AI scribe that transcribes encounters, structures clinical notes, and generates patient-facing instructions after visits. The platform supports dictation and real-time intelligence features marketed on Nabla’s site, with behavioral-health-specific templates co-developed with customers such as Catalight. Nabla emphasizes reducing unclosed charts — administrative backlog that delays billing and continuity of care — as a measurable operations problem, not only physician burnout sentiment.
Behavioral-health templates address diagnosis delivery visits where clinicians must maintain eye contact while capturing nuanced family concerns. Nabla’s May 2026 Catalight story quotes behavioral health managers on trust and empathy improvements when clinicians are not typing during sensitive conversations.
Who it serves
Nabla serves clinicians in health systems, digital clinics, and specialty practices including behavioral health, primary care, and hospital-affiliated groups. Catalight clinicians cited more empathic family conversations when documentation runs in the background, per Nabla’s May 2026 blog. U.S. deployments include UC San Diego Health and LCMC Health customer stories on Nabla’s blog, showing enterprise adoption outside Nabla’s French origins.
Nabla’s Catalight partnership highlights support for neurodiverse clinicians and non-native English speakers — workforce inclusion angles hospital DEI committees increasingly discuss when standardizing documentation tools across large clinician populations.
Company background
Alexandre LeBrun co-founded Nabla in 2018 with Delphine Groll (COO) and Martin Raison (CTO) per company materials. The team initially ran a digital clinic to observe real workflows before productizing ambient AI — a bottom-up product strategy Nabla describes in its Series C blog post. Nabla has raised venture funding including a $70M Series C noted on its blog, with investors including HV Capital and Highland Europe referenced in press materials.
LeBrun’s prior exits to Nuance and Facebook shaped Nabla’s engineering culture around shipping production AI rather than research demos — a distinction academic medical centers probe during pilot security reviews and note-quality evaluations.
Nabla blog posts on unclosed charts and E/M coding connect documentation quality to revenue operations — topics CFO stakeholders increasingly raise when ambient AI moves from innovation pilots to systemwide rollouts.
Product and AI capabilities
Nabla’s models combine speech recognition, medical NLP, and generative drafting tuned for clinical note sections and specialty templates. The platform generates structured patient instructions to help families retain care-plan details — particularly valuable in behavioral health where visits are information-dense. Nabla also discusses E/M coding documentation quality in product blog posts, connecting note completeness to compliance without claiming autonomous coding like Ambience Healthcare.
Nabla’s dual-hub Paris and New York structure supports EU data governance expectations alongside U.S. health-system procurement — an operational detail multinational ambient vendors must solve for enterprise legal review, not only model accuracy benchmarks.
Key developments
2018: Nabla founded in Paris by Alex Lebrun and co-founders. May 28, 2026: Catalight behavioral-health customer story published. Nabla continues Paris and New York operations per about page. Blog documents $70M Series C and digital-clinic origin validating workflows before general release. UC San Diego and LCMC Health customer stories appear on Nabla blog.
Why it matters
Nabla matters because ambient AI is becoming a global category — European vendors with U.S. health-system references compete on note quality and specialty templates, not geography alone. Behavioral-health documentation has different liability and empathy requirements than surgical subspecialties; Nabla’s Catalight story shows template depth as a moat. Compare with Abridge and Ambience Healthcare on enterprise EHR depth and coding features.
Patient instructions generated after visits help families retain care plans — a feature Nabla emphasizes for behavioral health where appointments are information-dense and follow-through at home determines outcomes.
Sector context
Nabla belongs in Brel’s AI in healthcare coverage under ambient clinical documentation alongside Abridge, Ambience Healthcare, and Suki AI. European AI drug discovery peers such as Owkin share Paris roots but sell into biopharma R&D rather than clinician workflows.
Behavioral-health template depth differentiates Nabla from primary-care-first ambient vendors — a segment growing as autism and developmental services face workforce shortages and documentation backlogs.
