# 30 leading consulting firms in Jakarta

Tamtam tracks 46 consulting firms headquartered in Jakarta. This list ranks the 30 largest by number of employees on LinkedIn, led by PT. SUCOFINDO, PwC Indonesia and Mitra Integrasi Informatika, PT. Their median headcount is 704. Half of them were founded in 1996 or later.

These are large consulting firms in Jakarta. They provide services across various sectors, including business consulting, professional services, IT consulting, and accounting. Companies like PwC Indonesia offer assurance, tax, and advisory services, while Mitra Integrasi Informatika, PT specializes in cloud services, big data analytics, and IT infrastructure. PT. Astra Graphia Information Technology (AGIT) focuses on digital strategy and ICT platforms, and KPMG Indonesia provides tax, business structuring, and licensing advice.

Many of these firms, such as PT. SUCOFINDO, LPPI - Your Strategic Partner, and PT Pertamina Training & Consulting, were founded between the 1950s and early 2000s. A notable pattern is the strong presence of state-owned entities or those with close ties to Indonesian institutions, like LPPI, an educational institution founded by Bank Indonesia, and PT Agrinas Jaladri Nusantara (Persero), a state-owned engineering management consulting firm.

## How this list is built

Every company on this list has a Tamtam company profile. 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. Last updated Nov 12, 2026.
