# The 25 largest financial services firms in Basel Tamtam tracks 25 financial services firms headquartered in Basel. This list ranks all of them by number of employees on LinkedIn, led by Helvetia Insurance Switzerland, Bank for International Settlements – BIS and Baloise CH. Their median headcount is 63. Half of them were founded in 1934 or later. These financial services companies in Basel are primarily established institutions in banking and insurance. Most are older firms, with a significant number founded in the 19th or early 20th century. The largest among them include Helvetia Insurance Switzerland, a quality-oriented insurer, and the Bank for International Settlements (BIS), an international financial institution promoting economic stability. Baloise CH provides insurance and investment solutions, while J. Safra Sarasin is an international private bank specializing in sustainable wealth management. A notable pattern is the strong presence of companies founded in the late 19th and early 20th centuries, such as Baloise CH (1863), CIC (Switzerland) (1871), and Pax Versicherung (1876). This indicates a long-standing tradition of financial services in Basel. The list also shows a mix of large-scale insurers and international financial bodies alongside more specialized private banks and cooperative banks like Bank WIR. πŸ‡¨πŸ‡­ Basel Β· 25 companies Β· Updated Nov 11, 2026 | # | Company | Industry | Headquarters | Employees | Founded | |---|---|---|---|---|---| | 1 | [Helvetia Insurance Switzerland](https://www.tamtam.ai/c/helvetia-insurance-switzerland) (helvetia.com)

The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking.
