What Substring GmbH does

Substring GmbH (operating as Substring AG; previously LeanBI AG, rebranded in August 2022) is a privately held Swiss data analytics and artificial-intelligence consulting firm headquartered in Worblaufen/Berne and founded in 2000. The firm serves Swiss enterprises across three primary verticals — Industry & Logistics, Public Transport, and Public Administration/Education — with secondary reach into Healthcare, Insurance, and Finance. Its offer is organised into four service lines: Data Consulting (strategy, roadmaps, data-landkarten and maturity assessments), Business Intelligence & Data Platforms (Medallion/Bronze-Silver-Gold architectures on Microsoft Fabric, Snowflake, Azure, and Databricks with dbt-based transformations), Operative Datasystems (data products, APIs, and automated workflows with Human-in-the-Loop processes), and Artificial Intelligence (machine learning, deep learning, RAG, generative AI, computer vision, and autonomous agents).

The firm's commercial model is pure professional services delivered through direct enterprise sales, structured as either project-based engagements (typically CHF 50,000–200,000; full data-warehouse implementations at CHF 150,000–400,000; proof-of-concept at CHF 40,000–80,000) or capacity-based retainers under a 'Data Team as a Service' model at CHF 15,000–50,000 per month. Customers include V-ZUG, Geberit AG, Swiss Post, BERNMOBIL, Basler Verkehrsbetriebe (BVB), PUBLICA, City of Lucerne, Basel Tourismus, SIPRO Steel Solutions, Stöcklin Logistik AG, and Amberg Technologies AG. The firm maintains no vendor reseller relationships, positioning itself as a platform-agnostic, independent consultancy that selects technology stacks based on client fit.

Technical differentiation rests on a proprietary predictive-maintenance platform (LeanPredict, born from the 2018 Innosuisse project and now deployed at Swiss Post for monitoring the Kippschalensorter sorting fleet processing 185 million packages annually), InnoSuisse-funded bridge defect recognition (2022), and multi-modal AI capabilities spanning predictive analytics, computer vision, acoustic signal processing, NLP/RAG, generative AI, and federated learning. Headcount is reported at 1–10; revenue is not publicly disclosed. Authorized signatories are Daniel Schwab, Nino Müller, and Eric Postler; the firm is founder-led with no external institutional investment.

Core offering

Substring provides consulting, implementation, and managed data services covering four practice areas: Data Consulting (strategy, roadmaps, maturity assessments), Data Platforms & Business Intelligence (data warehouse, lakehouse, Medallion architecture on Microsoft Fabric/Snowflake/Azure), Operative Datasystems (data products, APIs, automation), and Artificial Intelligence (ML, deep learning, RAG, computer vision, predictive maintenance). The company also offers two specialized offerings: LeanPredict (an AI predictive maintenance platform deployed at Swiss Post) and Data Team as a Service (embedded cross-functional team delivery on subscription or project basis).

Product overview

Substring is a Swiss data analytics and AI services company (formerly LeanBI AG, rebranded August 2022) offering a portfolio of consulting and implementation services organized around data-driven transformation. Their offerings are structured as four core service lines: Data Consulting (strategy, roadmaps, maturity assessments), Business Intelligence & Data Platforms (data warehouse, lakehouse, and platform implementation on Microsoft Fabric, Snowflake, or open-source), Operative Datasystems (data products, APIs, and automated workflows), and Artificial Intelligence (ML, deep learning, generative AI, computer vision, RAG). They also offer two specialized offerings: LeanPredict (predictive maintenance platform from their InnoSuisse project, now in production at Swiss Post) and Data Team as a Service (embedded team model for ongoing project execution). The company does not sell a single unified software product but rather provides technology-agnostic consulting and implementation services, typically working within clients' existing technology ecosystems.
