Sartissohn

What Sartissohn does

Sartissohn GmbH is a German IT company founded in 1991 and headquartered in Bardowick, Lower Saxony, with regional offices in Hamburg, Berlin, and Vechta. The company sells, implements, and supports SelectLine ERP software and an integrated document management system (DMS) to small and mid-sized businesses across Germany, bundling the core platform with proprietary add-on modules — Sartissohn Dataform, Sartissohn Waage, SmartMail, Scan Control Service, attRiBut Schnittstelle, Verschlagworter, SelectLine Extension, and docuvita Formularerkennung — plus certified DATEV interfaces for German fiscal compliance. The technology stack is platform-plus-modules, centered on SelectLine rather than a Sartissohn-built ERP, with the differentiation arising from proprietary extensions and deep consulting-led customization.

Commercially, Sartissohn operates a consultative, sales-led motion targeting German SMB and mid-market clients in manufacturing, retail, and professional services. Revenue is generated through quote-based ERP and DMS licensing, implementation and customization services, and ongoing support contracts on an annual cadence, supplemented by managed-services revenue from a legacy IT infrastructure division that, effective 1 August 2025, was divested to Wolkenhof GmbH. Following the restructuring, Sartissohn concentrates exclusively on software and business-process consulting, while Wolkenhof provides complementary networking, server, security, Microsoft 365, GREENCLOUD, and OFFICE services to the same client base; Sartissohn GmbH remains founder-owned under Managing Director Mike-Olaf Sartissohn and operates without external institutional capital.

Scale indicators2 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• DocuWare GmbH: Major cloud DMS vendor with strong DACH presence serving SMB through enterprise. Comparable to the document management side of Sartissohn's portfolio, with a more cloud-native platform and broader international footprint.
• CENIT AG: German IT consulting firm with enterprise content management and digital transformation practices. Comparable to the DMS and process-digitization portion of Sartissohn's business, particularly its mid-market enterprise software and consulting motion.
• ELO Digital Office GmbH: One of the largest independent DMS/ECM vendors in the DACH region. Comparable to Sartissohn's document management practice as a broad incumbent with overlapping DMS capability, but operating at significantly larger scale and across more enterprise customers.
• SALT Solutions GmbH: German IT consulting firm specializing in SAP and ERP for SMB/mid-market manufacturing and logistics. Comparable to Sartissohn's ERP implementation and process consulting business, though concentrated on SAP rather than SelectLine.
• Allgeier SE: German IT services group with ERP/DMS consulting and managed services exposure. Comparable to the broader consulting + software services dimension of Sartissohn, but at significantly larger scale and with a diversified portfolio across multiple ERP vendors.
• SelectLine Software GmbH: The underlying ERP platform vendor on which Sartissohn's entire software business is built. Comparable because SelectLine defines the product economics and roadmap that Sartissohn's add-on portfolio and consulting practice depend on; the relationship is closer to partner-plus-channel-competitor than pure peer.
• Bechtle AG: Large publicly listed German IT services and system house with strong SMB reach across the DACH region. Comparable as a broad channel for ERP, DMS, and infrastructure services, though at much larger scale and with a far broader portfolio than Sartissohn's focused SelectLine practice.

Emerging players

• agorum Software GmbH: German open-source DMS and document workflow vendor with a focus on SMB and mid-market. Comparable to Sartissohn's DMS and document automation offering, though more software-product-led than Sartissohn's SelectLine-centric consulting model.

Direct peers

• Windream GmbH: German DMS vendor selling through regional partners to SMB/mid-market customers. Comparable to Sartissohn's DMS go-to-market and customer profile, with overlapping document management and workflow automation positioning.
• Blue Ant GmbH: German ERP and DMS consultancy focused on SMB/mid-market implementations. Directly comparable to Sartissohn as a regional SelectLine-adjacent software and process-digitization partner serving similar DACH customers with similar consulting-led GTM.
