The Indonesian app where crypto meets US stocks - low fees, real licenses, and a stubborn habit of turning a profit.
Above: the Reku wordmark. What started as an Ethereum-mining side project in 2017 now guides hundreds of thousands of Indonesians through crypto and equities from a single wallet.
Reku is an Indonesian investment platform that does something most exchanges do not: it puts cryptocurrency and US equities side by side. In one app, a user in Surabaya can buy Bitcoin, stake Ethereum, trade futures, and pick up a slice of Apple or an S&P 500 ETF - all denominated in rupiah, all under one login.
The company was founded in 2017, when Sumardi Fung, Robby and Johny began mining Ethereum. That hobby hardened into an exchange, launched in 2018 as Rekeningku.com - Indonesian for "my account." In October 2022, fresh off an $11 million Series A, the company shortened the name to Reku and broadened the mission from crypto trading to something closer to a full investing companion.
The founding team did not come from a startup accelerator. They came from more than 15 years in Indonesia's futures-trading industry - a background that shows up less in marketing and more in the paperwork: registrations with BAPPEBTI, OJK, PasarFX, KBI and JFX. In an industry that often treats regulation as friction, Reku treats it as the product.
Indonesia has more than 20 million registered crypto investors, and most of them are new to it. Reku's core bet is that these newcomers do not want a casino - they want a guide. So the app is layered: simple spot buying up front, with futures, staking and curated packs waiting as users grow more confident.
Newcomers freeze at "what do I buy?" Reku Packs hand that decision to a research team, offering curated baskets of crypto, US stocks and ETFs.
After a wave of global exchange failures, Indonesians want assurance. Reku leans on local licenses and secure custody rather than promises.
Holding crypto in one app and US stocks in another is clumsy. Reku merges both, in rupiah, so a whole portfolio lives in one place.
Buy and sell 150+ crypto assets - BTC, ETH, USDT, SOL, XRP, DOGE and more - with fees positioned among the lowest in the market.
Access to 600+ US stocks and ETFs, so Indonesian investors can hold equities and crypto together in a single app.
Flexible 1-25x leverage with automatic take-profit and stop-loss controls for more experienced traders.
Passive income of up to 12.5% APY, with the freedom to unstake and withdraw to your wallet anytime.
Professionally curated investment packages mixing US stocks, ETFs and crypto - managed risk, selected by Reku's research and analyst team.
An over-the-counter desk for large-volume and institutional transactions, with premium support for high-value trades.
Reku competes with local exchanges like Indodax, Tokocrypto, Pintu and Pluang - but its crypto-plus-equities blend and compliance-first posture set it apart. The context it operates in is enormous.
Figures are company-reported and third-party market estimates. Indonesia ranks among the top nations globally for crypto adoption.
Reku earns primarily through trading and transaction fees across spot crypto, futures, US stocks and OTC, complemented by staking and curated Reku Packs. It serves two audiences at once: retail investors (D2C/B2C) and institutional clients through its OTC desk (B2B).
What distinguishes the model is discipline. While much of the sector chased growth at any cost, Reku turned profitable in 2024 - reporting that the first quarter was its strongest in two and a half years, with profit margins above 50%.
The founding team's regulated-finance background shaped a compliance-first culture.

Came from over a decade in futures trading; leads product and vision toward "smart investing for all."
