Alasco

Alasco is a Munich-based real-estate financial management platform for developers, asset managers, and construction teams, replacing spreadsheet-based cost control with integrated workflows across the development lifecycle. It spans three products - FinCon (financial controlling: projects, properties, contracts, invoices, change orders, cost elements, and financial reporting), CapEx (capital-expenditure planning and cost processing across assets and measures), and ESG (environmental data: buildings, utility meters, tenants, and consumption data). Alasco exposes a REST Public API that follows JSON:API principles, plus an official hosted MCP server for AI-agent integrations. It is ISO/IEC 27001 certified and serves institutional real-estate firms including Hines, JLL, and Ardian.

Alasco publishes 40 APIs on the APIs.io network, including Annual Consumption API, Asset API, Audit Log API, and 37 more. Tagged areas include Company, Ai Enterprise Software, Real Estate, Construction, and PropTech.

Alasco’s developer surface includes documentation, getting-started guide, API reference, changelog, authentication, engineering blog, pricing, and 24 more developer resources.
