What BASEAK does

BASEAK (legal entity: Balcıoğlu Selçuk Eymirlioğlu Ardıyok Keki Attorney Partnership) is an Istanbul-based, full-service commercial law firm founded in 2007 with nearly 100 professionals, including a dozen-plus equity partners and senior associates. The firm operates as the Turkish member firm of Dentons, the world's largest law firm, and serves both national and multinational clients — including Fortune 500 companies, Turkish conglomerates, financial institutions and emerging-growth technology companies — across twelve or more practice areas: corporate and M&A, banking and finance, capital markets, competition and antitrust, employment, project finance and infrastructure, real estate and construction, intellectual property and technology, litigation and dispute resolution, venture capital and private equity, tax, and public policy and regulation.

BASEAK generates revenue exclusively through professional-services fees — negotiated, quote-based engagements tied to transaction complexity, scope and counterparty. The firm does not sell a discrete software product, platform or technology stack; its core technology is human legal expertise augmented by sector specialisation (e.g., dedicated technology-sector and VC/PE practices). The firm operates from a single Istanbul office (Büyükdere Caddesi, Levent/Şişli) and delivers services primarily through partner-led advisory engagements, with cross-border mandates formally co-led with Dentons' international offices.

The firm has been involved in marquee Turkish transactions, including the Şişecam US$500 million Rule 144A/Reg S guaranteed notes issuance, the Nurol Holding US$200 million RegS Eurobond listed in Vienna, the Anadolubank US$250 million senior unsecured notes private placement, and the Grand Games US$70 million Series B round with Balderton Capital. Its competitive position is anchored by Dentons affiliation, top-tier third-party rankings (Chambers 'Türkiye Law Firm of the Year 2026', Chambers Band 1 for Real Estate, Legal 500 recognition in Banking & Finance), and partner continuity, with internal partner promotions rather than aggressive lateral hiring.

Direct peers

• YükselKarkınKüçük Attorney Partnership: YükselKarkınKüçük is a top-tier Istanbul-based full-service Turkish law firm with a comparable mix of corporate, banking & finance, project finance, energy, and dispute resolution work — directly competing for the same Türkiye enterprise and project-finance mandates BASEAK services.
• Paksoy Avukatlık Ortaklığı: Paksoy is one of the leading independent full-service Turkish law firms headquartered in Istanbul, with established practices in M&A, capital markets, banking and finance, and dispute resolution — the same core practice mix that BASEAK competes in for Turkish enterprise clients.
• Esin Attorney Partnership (Baker McKenzie Alliance): Esin is the long-standing Turkish member of Baker McKenzie Global and an Istanbul-headquartered full-service law firm with comparable scale and similarly diverse practice areas. It is the closest functional analogue to BASEAK in terms of its 'global network + local depth' model.
• Kinstellar: Kinstellar is a major emerging-markets law firm with offices across CEE including a presence in Istanbul, competing for the same cross-border corporate, M&A, and finance mandates that BASEAK and its Dentons affiliation serve.
• BTS & Partners: BTS & Partners is a Turkish law firm with significant corporate, M&A, banking, and finance practices serving enterprise and financial institution clients; it is a competing Istanbul-based full-service firm.
• Bener Law Office: Bener is a leading Istanbul-based Turkish law firm with strong practices in corporate/M&A, banking and finance, and dispute resolution, competing head-to-head with BASEAK for premium Turkish enterprise mandates (notably, it appears as a former employer of multiple BASEAK lawyers).
• Kılınç Law & Consulting: Kılınç is a major Istanbul-headquartered Turkish law firm providing full-service corporate, banking, finance, capital markets, and dispute resolution work, serving many of the same Turkish enterprise and financial institution clients as BASEAK.

Broad incumbents

• Dentons: Dentons is the world's largest law firm (80+ countries) and BASEAK's exclusive Turkish member-firm affiliate. It is both BASEAK's partnership channel and a broader competitor for cross-border mandates where Dentons' network coverage is the deciding factor.
• White & Case LLP: White & Case is a global Magic Circle firm with a leading Istanbul practice advising on cross-border M&A, capital markets, and project finance — directly competitive with BASEAK+Dentons for inbound and Turkish-side transactional mandates, and the former employer of founding partner Barlas Balcıoğlu.
• Baker McKenzie: Baker McKenzie is one of the world's largest global law firms and competes with Dentons (BASEAK's network) for cross-border Turkish matters, especially in capital markets, energy, and M&A where global coordination matters.
