DBI AG

What DBI AG does

DBI AG (Digital Building Industries AG) is a German AI-powered SaaS startup operating in the construction and building industry. Founded in 2018 and headquartered in Böblingen, Baden-Württemberg, the company develops two principal product lines: berta & rudi, an AI-driven suite for energy forecasting and optimal plant technology selection across residential, non-residential, district, and industrial buildings; and skizzly (Gebäudekonfigurator), an intelligent building configurator platform with an integrated app store and SDK designed for early-phase project planning. The underlying technology stack combines machine learning and genetic algorithms to deliver energy and CO2 calculations and variant analysis intended to make building planning more accessible.

The company serves building owners, architects, and planning offices in Germany, supported by offices in Böblingen, Esslingen am Neckar, Potsdam, and Oldenburg. DBI operates as a subsidiary of TMM Group, a 24-year strategic parent in technical building equipment, with overlapping executive leadership (CTO Dr.-Ing. Bernd Petraus serves both DBI and TMM AG; Klaus Ege and Valentin Ege serve on DBI's Vorstand). The GTM motion combines a self-service SaaS platform with a sales engineering function, reflecting a hybrid product-led and enterprise field-sales approach. With 21 employees, undisclosed revenue, and no external funding or named enterprise customers in the public record, DBI appears to be an early-stage, parent-backed SaaS vendor whose near-term growth depends on converting the skizzly launch into recurring subscriptions and scaling the sales engineering channel.

Core offering

DBI AG develops and sells AI-powered SaaS software for the building and construction industry. Its two main offerings are berta & rudi, which performs predictive energy consumption forecasts and calculates optimal plant technologies for residential, non-residential, district, and industrial properties, and skizzly (Gebäudekonfigurator), an intelligent building configurator that combines planning, data, and apps for early project phases. The software enables precise energy and CO2 calculations to support sustainability decisions in building pre-planning.

Product overview

Digital Building Industries AG (DBI AG) offers a suite of AI-powered SaaS solutions for the construction industry, comprising two main product lines: (1) berta & rudi – a software suite for energy system conception, where berta provides AI-driven energy consumption forecasting and rudi calculates optimal plant technologies, enabling precise energy and CO₂ calculations for sustainable building decisions; and (2) skizzly (Gebäudekonfigurator) – an intelligent building configurator platform for early project phases that unites planning, data, and applications in an integrated ecosystem with mapping, modeling, and an app-store for specialized tools. The products support comprehensive variant analyses and are designed to make energy calculations and CO₂ optimization accessible to all stakeholders in the building industry.

Expansion highlights5 records

Broad incumbents

• Autodesk: Dominant provider of BIM and CAD tools (Revit, AutoCAD) used by architects and planners that DBI targets. Autodesk layers AI-driven energy and sustainability analytics (Insight, Green Building Studio) directly into its workflow platforms, competing with berta & rudi from a position of massive installed base.
• Nemetschek Group: German-headquartered construction software group whose brands (Graphisoft/Archicad, Vectorworks, Solibri) serve the same AEC workflow DBI addresses. Strong overlap in target customer (architects, planners) and German market presence.
• RIB Software (Schneider Electric): Provider of construction estimation and project management software with growing exposure to building performance analytics. Targets similar enterprise construction firms and MEP planners in the German market.
• Trimble: Broad construction-technology vendor offering BIM, project management, and estimating tools. Trimble's portfolio increasingly includes building performance and sustainability workflows that intersect with DBI's energy optimization scope.

Direct peers

• IES (Integrated Environmental Solutions): Provider of building performance simulation and energy analysis software (IES VE) widely used by MEP engineers and architects for early-phase energy modeling. Competes head-to-head with berta for AI-driven energy forecasting and CO2 calculations.
• BuildingMinds: European digital building platform focused on portfolio-level sustainability and building performance data. Targets similar building owners and operators and competes with skizzly's digital ecosystem play for early-phase and operational building intelligence.

Emerging players

• Catenda (Bimsync): Open BIM collaboration platform for construction projects with a strong Nordic/German presence. Competes with skizzly on early-phase digital collaboration and a connected app ecosystem for building planning stakeholders.
• EDSL Tas: Developer of building performance simulation software (Tas Engineer, Tas Manager) for energy and sustainability analysis. Comparable to DBI's berta component for energy modeling and compliance workflows.
• archilyse / Nomad: Swiss-based AI platform for automated site and building analysis, focused on early-phase property evaluation. Shares DBI's AI-first approach to early-stage building planning decisions and target customer (developers, planners).

Regional players

• Greenlight Planet / GreenCalc: European-based energy calculation and certification tooling providers serving similar architect and planner use cases. Overlap with DBI on standardized energy and CO2 calculation workflows for residential and non-residential buildings.
