JAKARTA — Marina Budiman’s path to becoming one of Indonesia’s wealthiest business figures did not begin with mining concessions, consumer goods or a family-controlled banking empire. It started with a software installation project at a local bank.

Four decades later, the technology executive is a cofounder and major shareholder of PT DCI Indonesia Tbk., one of the country’s leading data center operators.

A mid-July 2026 snapshot based on the Forbes Real-Time Billionaires ranking estimated Budiman’s net worth at approximately US$5.7 billion, or about Rp102.9 trillion. The figure placed her eighth among Indonesia’s wealthiest individuals and made her the only woman in the national top ten.

Her business partner, DCI cofounder Otto Toto Sugiri, occupied the position immediately above her. Their presence in the ranking highlights the growing economic value of the physical infrastructure powering cloud platforms, artificial intelligence, digital payments and online services.

A Banker Drawn Into Technology

Born in 1961, Budiman studied finance and economics at the University of Toronto, graduating in 1985. She initially planned to build a career in banking and joined Bank Bali after returning to Indonesia.

Her career direction changed when she became involved in a project to install banking software. The assignment gave her an early view of how technology could reshape business operations. It was also at Bank Bali that she worked with Sugiri, who would later become her longtime business partner.

Budiman moved to information-technology company Sigma Cipta Caraka in 1989. She initially served as a project manager, later becoming chief financial officer in 2000 and sales and delivery director between 2008 and 2010.

Building Connectivity Before Indonesia’s Internet Boom

In 1994, Budiman and Sugiri helped establish Indonet, one of the foundational companies in Indonesia’s commercial internet industry.

Corporate disclosures state that Indonet was incorporated in March 1994 and began commercial operations the following month. The company describes itself as Indonesia’s first private internet service provider.

The venture was launched years before smartphones, streaming platforms and online marketplaces became mainstream. It placed Budiman and her partners at an early stage of Indonesia’s transition from isolated computer networks to an internet-connected economy.

Budiman, Sugiri and other founders eventually sold their Indonet interests in 2023 to Singapore-based regional data center company Digital Edge.

Moving From Internet Access to Digital Infrastructure

Budiman’s next major venture addressed a different layer of the technology ecosystem.

In 2011, she joined Sugiri, Han Arming Hanafia and other partners in establishing DCI Indonesia. Rather than selling consumer-facing digital products, DCI built the secured facilities required to house servers, networking equipment and mission-critical computing systems.

Forbes has described DCI as Indonesia’s largest data center operator at the time of its 2021 profile and identified the company as Southeast Asia’s first Tier IV data center.

DCI currently describes itself as Indonesia’s first and leading Tier IV operator. It also says it is the first and only operator in Southeast Asia to hold Tier IV Gold Certification of Operational Sustainability in addition to its design and facility certifications.

An Expanding National Platform

DCI’s footprint has grown beyond the three locations often cited in older company profiles.

Following the April 2026 launch of its E2 facility in Surabaya, the company’s platform now spans four areas: Cibitung, Karawang, downtown Jakarta and Surabaya. The Surabaya opening marked DCI’s first operational facility in eastern Indonesia.

Its E1 facility in Jakarta carries a total information-technology load of 19 megawatts and is positioned close to the country’s major internet exchanges. The company identifies E1 as the first and only Tier IV-certified data center in central Jakarta.

The expansion gives DCI exposure to rising demand from cloud providers, banks, telecommunications companies, e-commerce platforms and businesses deploying artificial-intelligence workloads.

The IPO Behind the Billion-Dollar Valuation

DCI Indonesia listed its shares on the Indonesia Stock Exchange on January 6, 2021.

The company offered 357.56 million shares at Rp420 each. The subsequent increase in DCII’s market valuation transformed the paper value of the founders’ stakes and helped place Budiman, Sugiri and Hanafia on global billionaire rankings.

Budiman owns 536.51 million DCII shares, equivalent to a 22.51% interest. She is the company’s second-largest individual shareholder after Sugiri, who owns approximately 29.9%.

She has served as DCI’s president commissioner since 2016, after previously holding the position of president director.

Why Her Forbes Ranking Keeps Moving

Budiman’s fortune is closely tied to the market price of DCII shares. It should therefore be understood primarily as the estimated value of her equity holdings rather than cash available for immediate use.

Forbes valued her wealth at US$8.2 billion when it published its Indonesia’s 50 Richest list in December 2025. By July 2026, real-time estimates had fallen to approximately US$5.7 billion–US$5.8 billion as market valuations changed.

Her worldwide position can also shift even when the estimated dollar value remains unchanged. Indonesian reports placed her at No. 712 globally on July 14 and No. 727 two days later.

A Different Kind of Indonesian Billionaire

Budiman’s rise illustrates a broader change in Indonesia’s business landscape.

Natural resources, manufacturing and financial services continue to produce many of the country’s largest fortunes. Yet the inclusion of two DCI founders in the national top ten demonstrates that digital infrastructure can now generate comparable levels of corporate value.

Her career also represents a long-term progression through several stages of Indonesia’s technology development: bank computerization in the 1980s, commercial internet access in the 1990s, and hyperscale data infrastructure in the cloud and AI era.

That journey has made Marina Budiman more than Indonesia’s wealthiest woman. It has positioned her as one of the business figures who helped construct the less visible—but increasingly indispensable—foundation of the country’s digital economy.
