Hermanto Tanoko and his brother Wijono are worth a combined $8.1 billion, per Forbes' "Indonesia's 50 Richest 2025" list, published 10 December 2025, ranking the family 9th richest in Indonesia. Hermanto is the more public face of the two: he serves as President Commissioner of Avia Avian, the paint company their father founded in 1978, while separately building his own conglomerate, Tancorp, across bottled water, bricks and property.

Forbes' annual list is the only figure this article treats as reliable, because it carries a clear date and a named methodology. Forbes also runs a separate real-time profile for Hermanto Tanoko individually, and several Indonesian outlets citing that tracker reported wildly different numbers through 2025 and into 2026: roughly $2.1 billion in December 2024, around $7 billion as of 30 September 2025, $4.2 billion by 18 October 2025, back up to $6.1 billion by early November 2025, and around $3.8 billion by 16 February 2026. Those swings are too large and too fast, sometimes reversing within three weeks, to reconcile without a primary Forbes snapshot for each one, so none of those individual figures is stated as fact here. No dated Bloomberg Billionaires Index figure naming either brother was found in this run's research.
The core is Avia Avian (AVIA on the Indonesia Stock Exchange), a decorative paint maker with roughly a quarter of the domestic market, founded by father Soetikno Tanoko in 1978 and taken public by the brothers in 2021. Hermanto serves as President Commissioner; Wijono is the other controlling family member.
Beyond Avia Avian, Hermanto has built a separate, wider portfolio under Tancorp Group:
CLEO), a bottled-water maker. Tancorp Global Abadi, a Tancorp vehicle, holds a controlling 56.12% of CLEO, per IDX-reported disclosures cited by Bisnis.com and Liputan6 in June 2026. Hermanto also holds a smaller direct stake, which grew to 243.71 million shares (1.01% of voting rights) after he bought 51.7 million more shares for about Rp19.6 billion in late June 2026, up from 192,012,158 shares (0.80%) beforehand, per the same reporting.RISE), a property and hospitality developer.That spreads the family's disclosed wealth across at least four separately listed companies plus wholly private Tancorp units, a structure closer to the multi-entity spread behind Tahir's Mayapada Group than to a single-stock fortune.
Avia Avian's own results kept growing through 2026: net profit for the first half of 2026 reached Rp938.42 billion, up 20.59% year over year from Rp778.20 billion in the first half of 2025, on net sales of Rp4.59 trillion, up 18.19% year over year, per Kontan and Bisnis.com, both reporting 18 August 2026. The stock itself traded well off its highs even so, with a 52-week range of Rp288 to Rp530 and a price of Rp356 as of 19 August 2026, per Investing.com.
A separate part of the portfolio moved far more dramatically, though no source connects it to the family's Forbes figure specifically. Tanrise Property (RISE) stock climbed as much as 1,092% year to date by 26 November 2025, according to Kabarbursa and IDX Channel, before later falling from a high of Rp7,725 to Rp835, per Kabarbursa. It is a reminder that smaller, thinly traded pieces of a diversified conglomerate can swing far harder than the flagship business, without necessarily moving the tracked net worth of the family behind it.
Harder to pin down than most fortunes in this series, and not because the underlying companies are private. Avia Avian, CLEO and RISE are all IDX-listed and required to disclose, but the family's wealth is split across all of them plus private Tancorp units, and this run found that secondary sources tracking Hermanto Tanoko's individual real-time figure disagreed with each other far more than usual, sometimes by billions of dollars within a few weeks, a caution this series has flagged before with Otto Toto Sugiri's DCI Indonesia figures. None of AVIA, CLEO or RISE appears in NetWort's own curated ticker lists, so none is linked directly from this article.
Avia Avian's paint cans sit in hardware stores across Indonesia, bought by homeowners who have never connected the brand to a name on a rich list, the same "hidden in plain sight" pattern this series already found in Djoko Susanto's Alfamart. The sharper lesson here is about tracking method: when a fortune sits across several separately listed companies rather than one, recirculated "net worth" figures can pick up the swings of whichever company happened to move that week, which is exactly why this article anchors on Forbes' own dated annual figure rather than any single real-time number found along the way. NetWort's asset screener shows how volatile smaller, thinly traded stocks can get relative to a large-cap name, the same gap this article found between Avia Avian and Tanrise Property.
