Munich-based Building Radar, led by Paul Indinger, is transforming construction sales with AI-powered lead discovery and project tracking, aiming to replace outdated spreadsheet reliance and enable earlier, smarter engagement in the sector.
Paul Indinger’s route into construction software began with a modest outsourcing experiment: he paid students in China to trawl architecture firms’ project pages for leads. What started as a side task for a carpet manufacturer eventually evolved into Building Radar, the Munich-based platform he now leads, which is used by companies including Schindler Elevators, Heidelberg Materials and Bosch to identify and pursue construction work.
Speaking in the interview with Aarni, Indinger argued that construction sales does not fit neatly into the standard B2B playbook. Unlike sectors where a deal moves along a single pipeline, construction involves both a commercial sales process and a separate project timetable. If a development has not broken ground, there may be nothing to sell. That mismatch, he said, is why the industry still relies heavily on spreadsheets, personal memory and scattered inboxes rather than systems designed for its own workflow.
Building Radar’s pitch is to close that gap. According to the company’s own materials, its platform scans millions of data sources in multiple languages, surfaces early-stage projects in a consistent format and plugs into major CRM systems including Salesforce, HubSpot, Microsoft Dynamics and SAP C4C. The company says the software can qualify leads, score projects and recommend next actions, while increasingly acting as the central workflow tool for a share of customers rather than just a source of intelligence.
Indinger also made a broader point about procurement in the sector: that too many product choices are driven by habit, not fit. In his view, better sales intelligence can help suppliers engage earlier and influence specifications before work reaches the contracting stage. Building Radar says it was founded in 2015 and is now pushing further into AI agents to reduce administrative effort and free sales teams for relationship-building. The company also says it has raised $7.2 million to expand AI-driven product development and grow in markets including the UK, the US and Canada.
