WIENER ADVOCATUR BUREAU

What WIENER ADVOCATUR BUREAU does

Wiener Advocatur Bureau is a Vienna-based commercial law firm founded in 2008 by Peter Melicharek and operated through Melicharek Rechtsanwalts GmbH, serving approximately six staff of whom four are practicing lawyers and advisors. The firm specializes in contentious corporate and foundation law, M&A, real estate transactions, foundation/trust governance, art & cultural law, and Legal Tech advisory, with an emphasis on conflict resolution alongside conflict avoidance. Client work targets enterprise and institutional mandates, including leading Austrian private equity funds, a Swiss major bank, four Viennese private banks, and real estate market leaders handling billion-euro transaction volumes; the firm also serves international clients from Europe, the US and Asia.

The firm has developed two proprietary Legal Tech products in-house: LeReTo, a multi-award-winning legal research tool originated in 2013 and since spun out into a separate company (LeReTo KG, with Veronika Haberler as CEO), and Online-Immo, launched in 2019 as a real estate transaction dashboard providing real-time status updates, digital workflow management and secure cloud-based e-files for property developers. Underpinning these is E-Akten, a high-security cloud infrastructure enabling client access to transaction documents in real time. The firm also acts as a Legal Tech advisor to startups and innovative companies in telematics, Big Data and blockchain.

The business model combines traditional professional services revenue (hourly or fixed-fee project billing for legal advisory and representation, with no public pricing disclosed) with subscription/standalone revenue from its proprietary Legal Tech products. Client acquisition is driven by direct engagement and professional referrals rather than digital marketing, leveraging memberships in STEP, AEA International Lawyers Network, Justinian Lawyers Network and an official partnership with the Vienna Stock Exchange for Private Equity and Venture Capital transactions. The firm is 51% owned by Peter Melicharek and 49% by Veronika Haberler, with no external institutional investors.
