Our AI-powered conversational search allows users to describe their project in natural language (French or English).
The system extracts key information such as:
- Project Intent: création d'entreprise (business creation), développement (development), embauche (hiring), équipement (equipment purchase), R&D (research and development), formation (training), export, rénovation (renovation)
- Business Stage: idée (idea phase), prototype, startup, lancement (launch), croissance (growth), mature company
- Sector: agriculture, technologie (technology), tourisme (tourism), santé (health), industrie (manufacturing), commerce (retail), artisanat (crafts), services, culture, environnement (environment)
- Geographic Location: région (region), département (department), commune (municipality)
- Budget Range: petit budget (small budget: <10K€), moyen budget (medium budget: 10K-100K€), grand budget (large budget: >100K€)
- Urgency: urgent (immediate need) or planifié (planned project)
- Experience Level: débutant (beginner) or expérimenté (experienced)
Search Methodology and Ranking Signals
Using extracted information, we match users with the most relevant subsidies from our database. Our ranking algorithm uses 8 signals (s_1 through s_8):
- Organism Preference (s_1): 37 trusted funding authorities ranked by reliability and coverage (94% linkage rate)
- Amount Range Compatibility (s_2): 8,695 patterns matching project budget to subsidy amounts (p25, p50, p75 percentiles)
- Company Similarity (s_3): 4,133 patterns analyzing successful applicants in the same sector/size (783 unique company profiles across 207 combinations)
- Geographic Distribution (s_4): Hierarchical region matching with progressive scoring (exact region: 1.0, neighboring region: 0.7, same economic zone: 0.5, national: 0.2)
- Timeline Compatibility (s_5): Deadline proximity and application urgency matching
- Program Affinity (s_6): Thematic alignment between project and funding program
- Recurrence Patterns (s_7): Annual vs one-time vs rolling subsidies
- Success Rate (s_8): Historical approval rates for similar applicants
As of October 2025, we have deployed 4 of 8 signals (50% methodology coverage) with proven 231.8% relevance improvement through 40-cycle iterative testing.
