Istrium

What Istrium does

Istrium is a privately-held French consulting firm (SAS) headquartered in Boulogne-Billancourt with a secondary office in Aix-en-Provence, specializing in public funding advisory for businesses. Founded around 2012 and operating for nearly 10 years, the firm identifies, secures, and manages public financing devices across France's fragmented ecosystem of approximately 2,000-3,000 programs managed by regions, tax authorities, Bpifrance, and various public agencies. Its service offering is organized around five domains — innovation financing (CIR/CII tax credits, JEI status, BPI programs, France 2030, FEDER), international export financing (Assurance Prospection, regional export subsidies), investment financing (SME loans, ADEME, ecological transition), sector-specific aid (FranceAgriMer viticulture, crafts and video-game tax credits), and public-actor support — supported by a complimentary 360-degree diagnostic completed in under 60 minutes.

The firm's core methodology combines a free eligibility diagnostic, end-to-end dossier preparation, submission management, and post-approval follow-up through fiscal controls. Istrium holds OPQCM professional certification (2025) and CIR/CII referencing from the Médiateur des entreprises (2025), formal credentials that position it as a trusted advisor in regulated innovation-tax-credit schemes. The firm does not deploy proprietary technology; its competitive differentiator is regulatory expertise and procedural mastery across 50+ funding mechanisms. A January 2025 strategic partnership with Favoreat extends its reach into the wine and spirits vertical through bundled marketing-and-financing offerings.

The revenue model is professional-services success fees: Istrium charges contingent fees on secured public funding, aligning its compensation with client outcomes. The client base spans mid-market and enterprise customers across education, wine and spirits, engineering, viticulture, and public-sector verticals, with named testimonials from Eduniversal, Saget La Perrière, and ER Ingénierie. Distribution is direct: two physical offices, phone, video, and website contact form, supplemented by content marketing (blog, LinkedIn, YouTube) and event participation (OSCI, Classe Export, GEIP, LEEM). The firm is led by Sebastien Langer and remains founder/management-owned with no external investors and €15,000 registered capital.

Core offering

Istrium is a French consulting firm that advises businesses on identifying, applying for, and managing public funding mechanisms including subsidies, tax credits (CIR, CII), and government-backed loans. The firm offers a complimentary 360° diagnostic, complete dossier preparation and submission, and post-approval follow-up support across four service domains: innovation financing, international export financing, investment financing, and sector-specific aid. Fees are charged on a success-based structure, meaning the firm is compensated only when public funding is secured for the client.

Product overview

Istrium operates as a unified consulting practice rather than a platform with discrete products. The firm offers comprehensive advisory services organized around five service domains: Innovation Financing (CIR/CII tax credits, BPI programs, France 2030), International Export Financing (prospecting insurance, regional grants), Investment Financing (SME loans, ecological transition), Sector-Specific Aid (viticulture, crafts, video games), and Public Actor Support. The 360° Funding Diagnostic serves as the entry-point service, providing free comprehensive assessment followed by end-to-end dossier management through submission and post-approval follow-up.
