Seabin™ And The $7 Trillion Nature Market
Ever wanted to invest in a profitable company that also helps the environment?
Seabin makes over $1 million per year, yet we don’t have a sales team or advertising budget. Imagine what we could do if we did!
Our goal is to raise investment to build a sales team and have an advertising budget so we can scale our revenue to create more impact and increase the value of the company.

Seabin Profitability, Melbourne and Mandatory Nature Reporting
Proven Profitability:
After years of resilience and lean growth, Seabin™ has reached profitability through disciplined restructuring, improved product offerings, and a stronger data-driven business model. With recurring revenue from environmental data sales and long-term partnerships, Seabin has demonstrated both financial sustainability and commercial scalability.
Melbourne Expansion:
Following our success in Sydney, Seabin is now aiming to scale operations to Melbourne’s Yarra River. This two-year, self-funded pilot will create new jobs and provide vital pollution data to help make the Yarra swimmable again. By replicating our Sydney model city by city, Seabin is building a national - and eventually global - network of real-time ocean health monitoring.
Mandatory Nature Reporting:
The upcoming introduction of Mandatory Nature Reporting in Australia and internationally represents a major revenue catalyst. Just as carbon reporting created the carbon market, nature reporting will drive billions in investment for credible, auditable environmental data. Seabin’s proprietary datasets position the company as a trusted supplier of plastic pollution reporting and footprint reduction services to governments and corporations. With profitability achieved, proven data systems, and expansion underway, Seabin is ready to scale - leading the charge in a $7 trillion nature market where accountability and environmental data drive real value.
Seabin: Cleaning Oceans, Creating Impact
Seabin generates revenue through:
- Corporate Partnerships - Companies partner with Seabin to support cleanup programs, meet ESG goals, and demonstrate environmental leadership.
- Impact Certificates - Certified environmental impact generated by Seabins are sold, allowing organisations and individuals to offset their plastic footprint and verify tangible results.
- Environmental Data Services - We monitor and remove plastic pollution at specific sites, delivering real-time data to support corporate reporting, compliance, and sustainability initiatives.
The $7 Trillion Nature Market
Seabin™ sits at the forefront of an emerging $7 trillion nature market, driven by the global shift toward Mandatory Nature Reporting and corporate accountability. While carbon markets focus on emissions, nature markets will require businesses to measure, report, and reduce their broader environmental impacts - including plastic pollution. Few companies are ready for this transition, giving Seabin a first-mover advantage as a proven, data-driven operator.
Over the past five years, Seabin has built one of the world’s largest baseline datasets on floating plastic pollution, capturing billions of litres of water and cataloguing millions of microplastics across Sydney Harbour. This dataset forms the foundation for scalable, compliance-grade environmental reporting services.
Seabin’s client portfolio includes more than 40 major brands and government partners - such as Sydney Airport, Multiplex, Sydney Metro and Infrastructure NSW that already pay for monitoring, reporting, and impact measurement. Backed by a global reputation for innovation, transparency, and credibility, Seabin is now expanding city by city, beginning with Melbourne’s iconic Yarra River. As nature reporting becomes mandatory, Seabin’s data, brand trust, and track record uniquely position it to lead this market - converting environmental impact into measurable business value.
Profitability And Proven Impact
Seabin™ has demonstrated strong commercial traction, achieving an average of $1 million in annual recurring revenue - without a sales team, ad spend, or marketing budget. This growth has come entirely from inbound demand, word of mouth, and Seabin’s global brand credibility.
Over five years, Seabin has evolved from hardware innovation to a profitable environmental data and digital impact company, providing compliance-grade reporting and plastic footprint reduction services. With 40+ major clients, Seabin’s organic client acquisition demonstrates clear market demand and product fit.
In 2024, Seabin launched its first digital impact products — including Impact Certificates that quantify litres filtered and plastic removed - converting real environmental data into verified, tradable business value. Market testing of these products has been highly successful, generating over $300,000 of impact allocation within the first six months (no sales team and no ad spend).
With five years of baseline data, a proven business model, and strong recurring revenue, Seabin is now poised for exponential growth. Scaling city by city, and supported by the coming wave of Mandatory Nature Reporting, Seabin is turning ocean data and measurable impact into a profitable, scalable global business.
First-Mover Advantage with Data-Driven Impa
While most competitors focus on selling hardware to marinas as once-off sales, Seabin™ chose a smarter path - investing in environmental data services and recurring revenue (ARR). Instead of chasing one-time hardware sales, Seabin targets governments and corporates that need credible, auditable environmental data for annual sustainability and compliance reporting.
This strategy has created a stable, compounding revenue model that doesn’t plateau - because sustainability reporting is required year after year. Seabin’s clients return annually for updated data and verification, generating repeat business and long-term relationships in a market that’s just beginning to formalise under Mandatory Nature Reporting.
Unlike hardware competitors, Seabin’s true value lies in its data and impact insights - measuring plastic pollution by brand, type, and volume to help clients reduce their footprint and prove progress. As nature reporting becomes mandatory, Seabin’s profitable, recurring, and data-driven model positions it to lead globally.

Why can't I download the offer document?
Paul S (OnMarket member) on 13/11/2025Hi Paul, im not sure but i will ask the On market team now. Thanks for your interest in Seabin. Pete
Pete C (Seabin Pty Ltd representative) replied to Paul S on 13/11/2025Same question as the other person - I need to be able to down load
mary sue r (OnMarket member) on 13/11/2025Hi Mary Sue, im not sure, but i will ask the On Market team also (same as above) Thanks for your interest in Seabin. Pete
Pete C (Seabin Pty Ltd representative) replied to mary sue r on 13/11/2025Hi all, The On Market team just enabled downloading of the offer doc. Thanks all. Pete
Pete C (Seabin Pty Ltd representative) on 13/11/2025on page 43 it talks about if the minimum spend is raised, the company may require further funding to carry out intended activities. Are the intended activities the melb opening or the sales team, or both? It also said about a potential second raise, will that then dilute the shares from this raise, and all previous raises? Can you elaborate on what the scale back operations will be, I assume operating the same as before the raise occurred? Thank!
Charlie S (OnMarket member) on 14/11/2025morning Charlie. First priority activity for us is to get a sales professional onboard so we can scale up our revenue. Melb expansion is if we hit our max target only. The text is mainly to advise that the company may do additional raises, and yes the shares will be dilluted because of that. But at the same time, and if we do things right, in theory your share value should increase.
Pete C (Seabin Pty Ltd representative) replied to Charlie S on 14/11/2025In previous On Market campaigns you could see how many individuals invested and the amount on a running basis - this does not seem to be showing.
mary sue r (OnMarket member) on 14/11/2025Hi Mary, im not sure why that is. We havent used On Market before. It might be becuase its still a private period? It goes public next Tuesday. We just passed our minimum target in less than 24hrs with $256K invested and 129 investors. Hope this helps a bit. i will ask OM team about seeing the live dashboard. Thanks for your interest. Pete - CEO & Co Founder
