Overview

SinnerSchrader was a German digital agency founded in Hamburg in 1996 by Oliver Sinner and Matthias Schrader. It emerged during the formative years of the commercial internet, initially operating as an online agency and helping businesses establish digital channels, particularly online shops. Its client base included both medium-sized companies and large international corporations. The company’s early headquarters were located in the former Johannes Krause tanning-machinery factory in Hamburg’s Ottensen district, and it later established offices in Berlin, Frankfurt, Munich, and Prague. The agency became a stock corporation in 1999 and floated on the Frankfurt Stock Exchange in November of the same year. The offering raised approximately €28 million. From 2003, its shares were traded in the German stock exchange’s Prime Standard segment. Like many internet-related businesses, SinnerSchrader was affected by the collapse of the dot-com boom. Sales and profits declined, and the company responded by reducing working hours. Co-founder Oliver Sinner left in 2002, after which Matthias Schrader continued to lead the business. SinnerSchrader returned to profitability in the 2004/05 financial year, and its recovery was later viewed as an example of a new-economy company adapting after the technology-market downturn. E-commerce remained central to the agency’s work, but SinnerSchrader also sought to broaden its capabilities through the acquisition of smaller agencies and the creation of an advertising agency. Its service scope developed around digital strategy, online retail, user experience, creative communication, and technology implementation. In 2006, the company established the Next Conference, an event focused on digital transformation and its effects on society and the economy. The conference became a visible part of SinnerSchrader’s contribution to the wider European digital-business community. Accenture announced its takeover of SinnerSchrader in 2017. Accenture initially secured approximately 60 percent of the share capital and subsequently increased its holding to more than 90 percent. Remaining shareholders were offered a cash settlement in connection with their exclusion from the company. SinnerSchrader ceased to be listed in 2019. After the acquisition, the agency operated within Accenture Interactive, with Matthias Schrader responsible for the business unit in Germany, Austria, and Switzerland for a period. In 2022, Accenture consolidated agencies acquired over several years under the Accenture Song name. At its 2022 general meeting, SinnerSchrader shareholders approved a merger with Accenture Digital Holdings, based in Kronberg im Taunus. The company was subsequently removed from the German commercial register. Matthias Schrader also left the business in 2022. SinnerSchrader therefore no longer operates as an independent corporate brand, although its capabilities and historical agency operations became part of Accenture’s broader digital, creative, marketing, commerce, and technology-services organization.

History

SinnerSchrader was established in Hamburg in 1996 by Oliver Sinner and Matthias Schrader as an online agency. The founders operated during the first major expansion of commercial internet services in Germany, with a focus on helping businesses create online presences and digital commerce operations. The company’s initial and enduring specialization was the development of online shops and other customer-facing digital services. Its customers included smaller and medium-sized enterprises as well as major international corporations. The agency initially operated from the former Johannes Krause tanning-machinery factory in Hamburg’s Ottensen district. As the business expanded, it opened additional offices in Berlin, Frankfurt, Munich, and Prague. In 1999, SinnerSchrader became a stock corporation and was listed on the Frankfurt Stock Exchange in November. The flotation raised about €28 million. Beginning in 2003, its shares traded in the German exchange’s Prime Standard segment. The collapse of the dot-com bubble created a severe challenge. SinnerSchrader experienced falling sales and profits and had to reduce working hours. Co-founder Oliver Sinner left the company in 2002, while Matthias Schrader continued to manage the business. The agency returned to profit in the 2004/05 financial year. Its recovery was subsequently regarded as an example of a former new-economy company surviving the technology-market correction by refocusing on sustainable client services. E-commerce remained an important business area, but the company pursued a broader digital-services model. It expanded through the acquisition of smaller agencies and established an advertising agency, adding creative and communications capabilities to its digital strategy, experience-design, and implementation work. SinnerSchrader also invested in industry discussion and community-building. In 2006, it founded the Next Conference to mark a company anniversary. The event addressed digital transformation and the social and economic consequences of technological change. Accenture announced the acquisition of SinnerSchrader in 2017. Accenture first secured around 60 percent of the share capital and then increased its stake to more than 90 percent. Remaining shareholders were offered a cash settlement associated with their exclusion. The company ceased to be listed in 2019. SinnerSchrader initially became part of Accenture Interactive, and Matthias Schrader led the relevant business in Germany, Austria, and Switzerland for a period. Accenture later combined agencies acquired across the digital, creative, marketing, and technology sectors under Accenture Song, formerly known as Accenture Interactive. In 2022, SinnerSchrader’s general meeting approved a merger with Accenture Digital Holdings. The company was subsequently removed from the German commercial register, and Matthias Schrader left the organization. SinnerSchrader is therefore best understood as a historical German digital-agency brand whose operations and capabilities were absorbed into Accenture’s integrated services structure rather than as an independent active company.
