Aventine Advisory GmbH i.G. (in Gründung) is an executive-led operating partner for travel technology, aviation distribution, digital marketplaces and e-commerce platforms. Independent counsel to owners, investors and boards in transactions, transformation and value creation — built on real P&L leadership, not consulting frameworks.
Three interlocking disciplines. One accountable partner at the table — in preventive structuring, operational execution and the realization of flow dividends after closing.
M&A advisory, complex carve-outs and technology-driven value creation in digital-analog matrix structures. Strategic framing, bid architecture and due diligence leadership on buy- and sell-side mandates. Minimizing transaction latency alongside private equity, family offices and strategic investors.
Post-merger integration (PMI), redesign of workflows and decision structures and software-enabled complexity reduction. Scaling decision throughput and sustainable EBITDA protection in international units with revenue responsibility of up to €240 million.
Interim mandates at executive level, strategic advisory and governance functions (certified supervisory board member) and operating partner roles. Assuming operational responsibility in succession scenarios, ownership transitions and the critical months of post-deal execution.
Executive leadership roles across global technology, travel and digital commerce platforms. Direct responsibility for international P&Ls, cross-border integrations and investor outcomes.
Portfolio revenue under direct P&L responsibility across international travel technology, aviation distribution and digital marketplace businesses, with full ownership of commercial outcomes and margin recovery.
Operating leadership at international technology platforms including Amadeus, TravelTainment, Amazon, eBay and HRS, spanning global P&L ownership, post-merger integration and cross-border transformation.
Post-merger integrations and carve-outs delivered across multiple jurisdictions and business cultures for travel technology and digital marketplace platforms, with hands-on accountability from day one through stabilization and value capture.
Deutsche Börse / Steinbeis-Hochschule — Supervisory Board Member Candidate (in preparation, expected completion Q4 2026). No completed board mandate is held; current roles include participation in the Amadeus Corporate Investment Committee and the Microsoft Innovation Review Board.
Aventine is led by Bernhard Steffens. More than two decades as Managing Director and Global Senior Vice President inside Amadeus, TravelTainment, Amazon, eBay and HRS — with direct P&L responsibility for international portfolios of up to €240 million in revenue.
The work begins where decks end: carve-outs that have to close, integrations that have to hold, P&Ls that have to recover, teams that have to perform. Owners, investors and boards engage Aventine when accountability and execution matter as much as analysis.
The strategic rigor of global technology leaders, combined with the value-driven, multi-generational thinking of the German Mittelstand — rooted personally in nine generations of family stewardship.
Mandates begin with a direct exchange between principals. Correspondence is received personally.
