Nirina RAZANAMPARANY
CTO & Co-Founder | Software & Product
Harvard University | Entrepreneur

With 15+ years at the intersection of deep tech, business, and strategy, I’ve built my career as a researcher, entrepreneur and software engineer.

Twice a founding engineer, I helped take Mobilosoft, a data marketing startup, to profitability and market leadership, and Stylonomy, an AI fashion commerce venture to a successful exit.

Trained at Harvard, I founded Code & Scale, a venture and software studio, where I’ve designed and delivered secure data and AI platforms for the United Nations, defense organizations, private equity and banking firms, and enterprises worldwide.

At SharpenCISO, I lead technology and innovation as a Co-founder & CTO.

Antoine THOREAU
CMO & Co-Founder | Sales & Marketing
Arts & Métiers ParisTech, HEC | Entrepreneur

Growth Hacker and Entrepreneur with 10 years of sharp expertise in B2B Marketing, focused on creating growth and maximizing asset value.

My career is highlightedby three successful exits: as Ex-Director of Outbound at LumApps (company sold in 2024 for €600M), as Ex-CMO of the AI startup Vizir, where I drove ARR growth from €280k to €600k (sold in 2023), and as Founder of AllSessions (annual turnover growth from 0 to €150k).

Backed by dual education in Engineering (Arts& Métiers) and Business School (HEC Paris), I have also applied my expertise serving over 20 SMEs and training over 1000 students, demonstrating strong strategic, operational, and teaching capabilities.

Built with a long-term vision to serve the best interests of our clients and partners, SharpenCISO is the product of a dedicated team — not simply the output of a no-code generation tool. Behind the platform stands a founding team supported by experienced developers and UX designers, committed to delivering excellence and scaling alongside our clients.
