About Pluvo

Pluvo is an AI-native Decision Intelligence platform helping companies make better decisions, faster and with more confidence. We connect strategy, operations, and financial planning in one system, so teams can move quickly without losing alignment.

Most businesses still rely on spreadsheets stitched together across departments, disconnected tools, and quarterly reports that are outdated before they're presented. We're building the alternative: planning that's transparent, adaptable, and accessible, without months-long implementations or opaque models that only consultants can understand.

We're a company moving fast, backed by the belief that planning should be a continuous, company-wide system of judgment rather than a quarterly finance ritual. If you're excited about building thoughtful AI products that simplify complex systems and help companies plan with confidence, you'll feel at home here.
