What is a joint stock company?
A joint stock company is a company whose capital is divided into transferable shares and whose shareholders are liable for the company’s debts only up to the capital they subscribed. It has separate legal personality: the company itself owns assets, signs contracts and can sue or be sued. These two features — limited liability and freely transferable shares — are what made the form the engine of modern capitalism, from the Dutch East India Company of 1602 to today’s listed corporations.
Joint stock company vs corporation vs LLC
The label varies by jurisdiction. In the United States and the United Kingdom, “joint stock company” is today mostly a historical or descriptive term — the same idea lives on as the corporation (US) or public limited company (UK). In civil-law countries it remains the formal name of the flagship corporate form: Aktiengesellschaft (AG) in Germany, société anonyme (SA) in France, and anonim şirket (A.Ş.) in Türkiye. The key contrast is with the limited liability company: an LLC (or Turkish limited şirket) suits closely held businesses, while the joint stock form is built for many shareholders, share classes and capital markets.
The Turkish joint stock company (anonim şirket)
Under the Turkish Commercial Code (TTK Art. 329 et seq.), the A.Ş. can be formed by a single shareholder, requires minimum capital of TRY 250,000 (TRY 500,000 under the registered-capital system), and is managed by a board of directors that may consist of one person. Shares are in principle freely transferable — transfer restrictions must be built in through the articles of association. Regulated businesses (banks, payment institutions, insurers, crypto asset service providers) must incorporate as an A.Ş.
Why startups incorporate as an A.Ş.
Nearly every venture-backed Turkish startup is an anonim şirket, because the form supports what venture deals need: multiple share classes and preferred-stock-style privileges (TTK Art. 478), conditional capital increases for ESOPs, and clean share transfers at investment rounds or a US flip-up. Investors will typically require conversion into an A.Ş. before closing if the target is a limited şirket.
