Indonesian climate tech startup Rekosistem has secured $7 million in a funding round led by existing backers Saratoga Investama and K3 Ventures, according to a statement on Tuesday.
The round also saw participation from AppWorks, Skystar Capital, Bali Investment Club (BIC), Orvel Ventures, and Michael Sampoerna’s Office.
Saratoga Investama invested via its vehicle Baltimore Investments Ltd.; while K3 Ventures invested via K3 Aquarius Fund IV, according to the company’s filings with Singapore’s Accounting and Corporate Regulatory Authority (ACRA) reviewed by DealStreetAsia.
“[..] With the continued support from our investors, we are poised to accelerate our mission of transforming waste management into a more sustainable and circular model. This investment will serve as a great leverage to drive exponential growth for the greater good of Indonesia’s waste management industry through strategic expansions and enhanced waste recovery digital ecosystem and mechanizations [..],” said Ernest Layman, co-founder and CEO of Rekosistem.
Rekosistem had raised $5 million in August 2023, in a round led by Skystar Capital and supported by East Ventures, Provident, and other investors.
According to DealStreetAsia DATA VANTAGE, the startup has raised a total of $12 million since its inception. Layman holds the largest stake of 29.61%, followed by Saratoga Investama with 13.54%, and co-founder Joshua Valentino with 11.06%.
Top shareholders of Rekosistem
With the new capital, Rekosistem plans to expand its waste processing infrastructure across more Indonesian cities, enhance its proprietary OS using automation and machine learning, increase the diversity of waste types it can process (targeting more than 70% recyclability), and scale its Extended Producer Responsibility (EPR) programs, which help brands take responsibility for post-consumer waste in line with emerging regulatory requirements.
Founded in 2021, Rekosistem offers integrated waste management and recycling services to optimise the waste value chain. It has four main products—Reko Pick-up (responsible and zero waste management services); Reko Hub (material recovery facility); Reko Drop-In; and Reko Waste Station, which aims to transform waste into recycled materials and renewable resources.
The company primarily adopts a B2B and B2B2C model, offering mobile and web-based services for residential, commercial, and municipal clients. It claims to have achieved a compound annual growth rate (CAGR) of 442% through 2024, positioning it as one of the fastest-growing climate-tech companies in the country.
As of March 2025, Rekosistem has served over 90,000 households and 200 businesses, processed more than 3,500 tons of waste per month across its 15 Reko Hubs, 40 Reko Waste Stations, and over 600 Reko Mitra partner locations. Its client base includes major brands such as Danone, Nestlé, Procter & Gamble, Toyota Astra Motor, and Ciputra Development. The company claims to have reduced over 75,000 metric tons of CO₂ emissions by replacing virgin materials with recyclables.
Climate tech sector
The climate tech sector has emerged as a rare bright spot amid the persistent slowdown in Southeast Asia’s venture capital activity, revealed DealStreetAsia – DATA VANTAGE‘s recent report titled The State of Climate Tech in SE Asia 2024.
In the first 11 months of 2024, the sector’s share of total funding value in Southeast Asia rose to 11.1%, its highest level to date, steadily increasing from 2.3% in 2021, highlighting growing investor confidence in climate tech as a key vertical within the broader innovation ecosystem.
Share of climate tech funding value versus other sectors in SE Asia
The acceleration can be attributed to heightened investor focus on environmental, social, and governance (ESG) principles, increased climate awareness, and favourable government policies promoting sustainable solutions, the report noted.
Indonesian climate-tech startup Nafas is in the final stages of closing a nearly $3-million investment round with Rigel Capital and Qatar Development Bank (QDB), DealStreetAsia reported last month.
Nafas plans to use the funding to support expansion across the Middle East and Asia and scale its Clean Air Zones subscription service — a solution that integrates air quality monitoring, filtration, and AI-driven insights, which targets indoor environments, from classrooms to corporate towers. The service is built to improve respiratory health and protect people in regions suffering from high levels of air pollution.
DealStreetAsia had reported in February that Swiss impact investor responsAbility is looking to allocate $180 million annually into South and Southeast Asia’s climate tech sector for the next three to four years, through credit-focused strategies from its climate funds.
