Sustainable Investment Exchange

What Sustainable Investment Exchange does

Sustainable Investment Exchange (SIX), founded in 2023 and publicly launched in July 2024, is an Australian private company headquartered at co-working spaces in Melbourne and Sydney. It operates a self-serve digital share trading platform targeting individual retail investors, SMSFs, trusts, and company accounts. The platform enables users to trade ASX-listed shares and ETFs while accessing proprietary ethical screening tools (Ethical Filters) and human-written ESG research (Ethical Profiles) on Australia's largest listed companies. A distinctive capability is integrated shareholder activism: users can join campaigns targeting ASX issuers on climate, nature, and social issues, pool shares to meet the 100-shareholder threshold required to lodge resolutions, and participate in AGM voting under direct CHESS-sponsored ownership with their own Holding Identification Number.

The platform is built on conventional Australian fintech infrastructure: FinClear Execution Ltd acts as the Approved ASX Market Participant executing all trades, while Frankie Financial and SwiftID provide identity verification for onboarding. Technology differentiators are domain-specific (ethical screening tied to human-curated ESG data) and community-driven (the activism layer that mobilizes retail shareholders to co-file resolutions with NGO partners such as the Australian Conservation Foundation, The Wilderness Society, Market Forces, and the Australasian Centre for Corporate Responsibility). Quantified campaign outcomes include a world-record 22.7% vote at ANZ on deforestation ($13.5 billion in supporting shares), a 30%+ vote at Woolworths on the Maugean Skate resolution, and corporate commitments from Webjet (animal welfare) and Woolworths (deforestation).

Scale indicators3 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• CommSec: Australia's largest retail broker, operated by Commonwealth Bank, providing ASX and international trading plus extensive research. Represents the entrenched incumbent whose scale and brand SIX positions itself against with its 'Like CommSec for ethical investors' positioning.

Direct peers

• Stake: Australia-founded brokerage offering ASX and US share trading via a mobile-first self-serve platform. Comparable product (retail self-directed investing) and customer base, but Stake does not offer ESG screening or shareholder activism tooling.
• SelfWealth: Australian retail share trading platform offering low-cost ASX and US equities brokerage to individual investors. Direct competitor to SIX on the core trade-execution experience, although SelfWealth lacks an ethical-investing angle and an activism layer.
• Superhero: Australian retail share trading platform offering low-cost ASX and US equities execution via a self-serve app. Competes head-to-head with SIX for the same retail trading customer, differentiated mainly by the absence of an ethical-investing and activism proposition.
• Pearler: Australian long-term investing platform for retail investors using ETFs and direct shares. Targets a similar values-aligned, buy-and-hold retail audience as SIX, with comparable self-serve onboarding, though without the activism component.

Others

• Verve Super: Australian ethical super fund focused on gender equality. Overlaps with SIX on the ethical-finance audience and shares a founding-team connection, but operates as a fund rather than a trading platform.
• Future Super: Australia's largest ethical super fund ($16Bn AUM), founded by SIX's CEO. Competes indirectly for ethical-investing dollars and is also a SIX campaign partner, illustrating both the partnership and the adjacent competitive dynamic.
• Australasian Centre for Corporate Responsibility (ACCR): Australian non-profit specialising in strategic shareholder advocacy and climate-related resolutions at ASX-listed companies. Adjacent to SIX on the activism methodology and a named campaign partner, but operates on an institutional/non-profit model rather than retail trading.
• Market Forces: Australian non-profit running shareholder campaigns on climate and fossil-fuel financing at major banks and insurers. Co-files resolutions with SIX and overlaps on the activism playbook, but does not offer a retail trading product.

Emerging players

• Australian Ethical: Listed Australian ethical asset manager offering managed funds and superannuation with strict ESG screens. Competes for the same values-aligned capital pool as SIX but via managed funds rather than direct share ownership and activism.
