Software Development Berlin, BE 11–50 employees Founded 2020 Public Company

koppla builds a collaborative scheduling tool for construction project management, with a tech stack centered on Vue, TypeScript, GraphQL, and real-time WebSocket communication—a classic modern SPA architecture for handling dynamic site data. Hiring is sales-led (4 open roles) and design-heavy (2 roles), reflecting a pivot toward upper mid-market and enterprise customer acquisition; engineering is lean (1 role), suggesting the platform core is stable and growth is now gated by go-to-market rather than product development velocity.
