STELACON

What STELACON does

STELACON GmbH is a privately held SAP consulting and development firm headquartered in Hamburg, Germany, founded on 11 June 2012 by three long-time colleagues. The company delivers end-to-end SAP ERP services — from conception and process modelling through implementation, custom ABAP development, and post-go-live optimization — to medium-sized and large enterprises primarily in Germany and other European markets (Netherlands, Switzerland, Spain, Italy, Portugal, France, Great Britain, Denmark). Its service portfolio spans Sales & Distribution, Manufacturing Logistics, Material Management / EWM, Product Lifecycle Management, Human Capital Management, Accounting & Controlling, BI & Reporting, and dedicated S/4HANA Transformation Services covering Brownfield, Greenfield, and GreenfieldPlus migration approaches.

The firm's core technology stack is anchored on SAP ECC, SAP S/4HANA, SAP Fiori/UI5, ABAP development, and Core Data Services. It differentiates through two proprietary ABAP-based tools: the StelaConversionCockpit (SCC) for system-wide data field value conversions with RapidRun technology, and the STELACON Material Variants Generator for automated creation of bills of materials, routings, and plan calculations. Additional proprietary assets include the KITS solution template for fast SAP rollouts to small European subsidiaries (originally built for Vitakraft) and a co-developed SAP e-invoicing solution built with partner ecosio for mandatory EU e-invoicing from 2025.

STELACON operates three German offices (Hamburg HQ, Munich, Bad Malente), employs 20+ colleagues including 11 consultants and developers in Munich, and is led by co-founders Holger Bärenwald (CEO, 30+ years SAP experience) and Jörg Fricke-Kranz (Management Board, 25+ years SAP experience), with Andreas Schaller as Head of Development and Munich site manager. Revenue is generated through project-based professional services engagements with enterprise clients, with no public pricing disclosed and a free initial consultation offered via direct enterprise field sales. Go-to-market is supported by event sponsorship (SAP Fiori Innovation Day 2025 Silver Sponsor), a corporate blog, X/Twitter presence, and SAP community engagement under SAP PartnerEdge open ecosystem membership. The company has received the TOP Consultant award for five consecutive years (2021-2025) based on customer satisfaction ratings, with named enterprise customers including Springer Nature, SPIEGEL, Getinge, Karl Mayer, Vitakraft, Jebsen & Jessen, Altendorf, and Metallwerk Elisenhütte.

Direct peers

• SNP Schneider-Neureither & Partner: Mannheim-based SAP partner specializing in data migration and system landscape optimization for SAP transformations — the same niche that STELACON's StelaConversionCockpit addresses. SNP's CrystalBridge platform directly overlaps with STELACON's SLO/data-conversion services.
• cbs Corporate Business Solutions: Heidelberg-based SAP global partner focused on S/4HANA transformations and industry-specific ERP for mid-market industrials. Directly comparable in cross-module SAP consulting, transformation methodology, and target customer (industrial Mittelstand).
• Sycor: Göttingen-headquartered SAP consulting firm with strong Microsoft and SAP practices serving German mid-market manufacturers. Comparable in customer segment, geographic focus, and full-spectrum ERP consulting/depth across logistics and accounting modules.
• MHP (a Porsche company): Stuttgart-based SAP and IT consulting firm with a strong automotive and manufacturing industrial focus. Comparable as a German-headquartered SAP transformation partner for enterprise clients, though MHP has substantially greater scale than STELACON.
• All for One Group: German-headquartered SAP consulting and managed-services specialist serving mid-market enterprises across the same DACH footprint as STELACON, with deep SAP ECC/S/4HANA implementation capability. Closely comparable in customer segment (German Mittelstand) and core offering (ERP consulting + managed services).

Broad incumbents

• Atos (SAP practice): Global system integrator with a sizeable German SAP consulting practice serving large enterprise S/4HANA migrations. Overlaps with STELACON in core SAP services but competes primarily at the mega-deal tier where STELACON is not positioned.
• Accenture (SAP practice): Global SI with one of the largest SAP S/4HANA delivery footprints worldwide, including a sizable German practice. Directly competes for SAP transformation mandates but at enterprise scale far beyond STELACON's mid-market focus.
• Deloitte (SAP practice): Big Four firm running large SAP S/4HANA transformation programs across Germany. Competes for the same enterprise transformation RFPs as STELACON but operates at vastly larger scale and offers adjacent consulting (strategy, tax, audit).
• Capgemini Invent / SAP Practice: Global SI with deep SAP S/4HANA delivery capability and a dedicated German Mittelstab offering. Overlaps with STELACON in SAP transformation services but at materially greater scale and with broader portfolio (cloud, data, engineering).
• SAP SE (Consulting organization): SAP's own premium engagement and Customer Success organization directly competes with partner firms like STELACON for S/4HANA implementations, while also being the platform vendor whose ecosystem creates the firm's opportunity. SAP's expanding internal capacity is a structural overhang on partner economics.
