What is a joint stock company?
A joint stock company is a company whose capital is divided into shares and whose shareholders are liable only up to the capital they subscribed. In Türkiye it is the anonim şirket (A.Ş.), regulated by the Turkish Commercial Code, and it is the closest Turkish relative of a Delaware corporation, a German AG or a French SA. It is the only Turkish company type whose shares can be offered to the public, which is why every company heading toward institutional investment or an exit eventually meets it.
The A.Ş. runs on two organs: a general assembly of shareholders and a board of directors, which can consist of a single member and need not include a shareholder. A single-shareholder A.Ş. is fully valid. The minimum share capital is 250,000 TL for the standard system and 500,000 TL for companies adopting the registered capital system, and shares can be issued in registered form and transferred without a notary, a practical advantage over the limited şirket that matters more than it sounds once investors, option pools and exits enter the picture.
Joint stock company or limited şirket?
Most Turkish startups are born as one of the two and the choice shapes the cap table for years:
| Issue | Joint stock (A.Ş.) | Limited (Ltd. Şti.) |
|---|---|---|
| Share transfer | No notary; endorsement and delivery for registered shares | Notarised deed plus registry, general assembly approval |
| Public offering | Possible | Not possible |
| Shareholder liability for public debts | None beyond capital | Partners can be personally reached for tax and social security debts |
| Minimum capital | 250,000 TL (500,000 TL registered capital system) | 50,000 TL |
| Investor expectation | Standard for VC rounds, ESOPs and exits | Usually converted before an institutional round |
The pattern in practice is simple: bootstrapped businesses often start as limited şirket for the lighter setup, and convert to A.Ş. when a priced round, an option plan or a flip-up appears on the horizon. Conversion is routine but takes weeks, so doing it before the term sheet, not after, saves a closing.
Why investors insist on it
Venture documentation assumes share classes, preferred rights, board seats and transfer mechanics that only the A.Ş. supports cleanly under Turkish law. Privileged shares carrying liquidation preference or veto rights, redeemable ESOP pools and drag and tag structures are all drafted onto A.Ş. share ledgers. The articles of association carry part of that architecture and the shareholders’ agreement carries the rest.
Can a single founder own a joint stock company?
Yes. A single-shareholder A.Ş. has been valid since 2012, and a single-member board is enough. The company must notify the trade registry when it becomes single-shareholder, but nothing about the form requires a co-founder.
Is the 250,000 TL minimum capital paid immediately?
A quarter of the subscribed cash capital must be paid before registration and the rest within twenty-four months. For most startups the practical answer is that the initial outlay is 62,500 TL, not the full number on the articles.
