About us

Fullinfo is a self funded software company building a new way to search and use company data.

We are developing a one stop platform that helps sales and marketing teams discover leads, contacts and insights. Fast, intuitive and deeply searchable. Think Google Search meets CRM enrichment. With filters, structured results and powerful integrations like Hubspot and Salesforce. The frontend is built in Angular using TypeScript and GraphQL.

We are not dependent on investors and have no funding pressure. That gives us the freedom to focus on quality and build a product we actually believe in.

• Fully remote work
• A flat structure with lots of ownership
• A motivated team that values quality and clarity
