NutraVector • Temps plein

Dec 2023 - Present • 2 yrs 5 mos

NutraVector is an AI-first B2B SaaS platform for the nutraceutical industry (brands, contract manufacturers, ingredient suppliers). The goal is to digitize and accelerate the full lifecycle: sourcing → compliance → formulation → industrialization → go-to-market, with a workflow-driven approach and strong GDPR requirements. Role: Founder / Product Builder Discovery & scoping: market research, problem statements, segmentation (brand / manufacturer / supplier personas), journey mapping, KPI definition, MVP scope. Product design: modular functional architecture, impact/effort prioritization, backlog, user stories, specs, acceptance criteria, go-to-market strategy and pricing hypotheses. No-code / low-code build: rapid prototyping, user testing, iterations, integrations, automations (workflows, notifications, scoring, dashboards). Applied AI: designing specialized module copilots; data extraction & structuring (technical docs, ingredient sheets); classification; scoring; deliverable generation; audit trail logging and safety guardrails. Data & compliance: entity modeling, document quality/traceability, multi-country requirements, consent management, access security (multi-tenant, roles, validations). Real complexity (what’s actually being built): Multi-stakeholder product with distinct business logics (brand vs manufacturer vs supplier) and collaborative workflows Structured data + documents + automations + AI, requiring reliability and traceability Premium experience: guided onboarding, dashboards, standardized processes, reduced time-to-market Typical deliverables: MVP roadmap, functional specifications, prototypes, user journeys, automated workflows, data schemas, product documentation, and execution plan.
