Company profile

researched Sep 2026

Mushroom Material, which has rebranded as Naturally Genius, develops protective packaging material grown from mycelium (the root structure of fungi) combined with agricultural waste such as hemp, straw, wood chips, sawdust, cardboard and food waste. The material is positioned as a drop-in replacement for expanded polystyrene (EPS/Styrofoam), offering impact protection, thermal insulation, sound dampening and structural support, with added water resistance and fire retardancy, and is described as home compostable, breaking down in a home compost or garden within months.

The company's central technical claim is a pelletised production method: rather than growing fungi for one to two weeks inside a shaped mould — a manual process the company describes as hard to scale — it grows large volumes of fungi-based pellets that are coated with a binding agent or biopolymer and then compression moulded into customer-specific shapes such as corners, boxes, cylindrical protectors, clips, flat sheets and wine bottle protection. Because the pellets run through existing EPS moulding equipment, the company positions the material as compatible with established manufacturing lines and supply chains.

Commercially, the company offers design services around a customer's product and performance requirements, manufacture of finished packaging, and supply of pellets for customers to mould themselves. It operates from Auckland, New Zealand and Singapore, and is registered in Singapore.

Founding story

Founder Shaun Seaman has said the idea began in 2018 when he paddled out to surf off the coast of Indonesia and found the water full of plastic bags and broken Styrofoam. Researching the problem in New Zealand, he identified expanded polystyrene as a priority target and teamed up with engineer Jotinder Singh; after about three years of experiments they developed compostable mycelium pellets able to run through existing EPS moulding lines.

Business model

The company sells finished protective packaging designed around a customer's product, or supplies its mycelium pellets for customers to mould on their own existing equipment. It also offers packaging design services and handles licensing enquiries, and has described a longer-term intent to license its technology globally after building commercial-scale production.

Revenue is expected from sales of finished mycelium packaging and of pellets sold to manufacturers for moulding on their own lines, with technology licensing described as a longer-term global expansion route. Deliveries to existing customers were planned to begin in 2025.

Traction

More than 200 companies have expressed intent to purchase, with some having signed agreements to buy once production reaches scale, including large furniture and electronics retailers; one report names Estée Lauder, Panasonic, Ikea and Toshiba among interested parties. A 1,300 sqm pilot plant in Mount Roskill, Auckland, reported to cost around $5 million, was funded by the 2024 seed round, with samples targeted for late 2024 and deliveries from 2025.

Latest developments

Mushroom Material has rebranded as Naturally Genius, keeping the same team, technology and mission. The company states it has raised US$5.7 million in total, describes itself as on the verge of commercial-scale production, and says its seed round closed in 2024 with a Series A in preparation. Recent activity includes a 2026 Earthshot Prize nomination and scheduled appearances at JEC World in Paris (March 2026) and Cleantech Forum Asia in Singapore (May 2026).

▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

The company positions itself against incumbent EPS/Styrofoam packaging and against earlier mycelium packaging approaches that grow fungi directly in moulds, which it characterises as too expensive and insufficiently scalable for large global distributors. It has been named to Cleantech Group's 2024 "50 to Watch" list, listed among top sustainability startups in New Zealand, named "Next Big Thing" at the 2025 SBN Awards and a Sustainable Business Network Next List finalist, and nominated for the 2026 Earthshot Prize.

Its pelletised growth method is presented as the key differentiator from conventional mycelium packaging, which grows fungi over one to two weeks inside individual moulds. Pellets can be produced in bulk and bound or compression moulded into customer-specified shapes using standard EPS moulding equipment and existing supply chains, which the company frames as addressing both scalability and cost-competitiveness, alongside home compostability and a claimed material performance match to polystyrene.

Technology

Mycelium is grown on agricultural and organic waste to produce large volumes of pellets, which are coated in a binding agent or biopolymer and compression moulded into customised shapes. The approach is designed to integrate with existing styrofoam production lines and moulding machinery rather than requiring new equipment. The company describes performance comparable to polystyrene for impact resistance and thermal and acoustic insulation, low density, natural water resistance and fire retardancy, and cites a design requirement of shelf stability for up to two years alongside compostability in weeks to months.

Go-to-market

The company works directly with manufacturers and distributors that currently use EPS, designing replacement packaging around their products and offering samples and specifications through its website. It has built pipeline through inbound interest, industry events and accelerator and trade programmes, including Techstars in Singapore, SWITCH in Singapore, Cleantech Forum Asia, JEC World in Paris and the ASB CleanTech Trek.

Manufacturers, brands and distributors shipping products that currently rely on single-use polystyrene foam protection, including electronics, appliances and furniture companies, as well as businesses facing plastic packaging taxes, bans and recyclability targets in markets such as the EU, UK, US, Australia, New Zealand and Singapore.

Geography

Headquartered in Auckland, New Zealand, with an office in Singapore and the company registered in Singapore; a 1,300 sqm pilot plant is being established in Mount Roskill, Auckland. The company supplies businesses globally and has cited commercial interest across the Asia region, with a stated long-term plan for a commercial-scale plant in Southeast Asia.

History

Founded in 2020 by Shaun Seaman and Jotinder Singh, the company followed roughly three years of kitchen-bench and garage experimentation that produced compostable mycelium pellets compatible with existing EPS moulding lines. It raised a pre-seed round of $470,000 led by Icehouse Ventures, and became the second New Zealand company accepted into the Techstars accelerator in Singapore. In August 2024 it announced a seed round of over US$5 million to fund a 1,300 sqm pilot plant in Mount Roskill, Auckland, with the plant intended to open officially by the end of 2024 and customer deliveries to begin in 2025. The company states total funding of US$5.7 million and subsequently rebranded as Naturally Genius.

Risks & controversies

The founder has described difficulty raising capital in New Zealand and said offshore investors produced a more favourable valuation, and the company registered in Singapore. Scaling remains the stated principal challenge: the business plan requires continued fundraising, including a Series A and an estimated $50 million commercial-scale plant in Southeast Asia. Technical constraints include balancing up to two years of shelf durability with rapid degradation, and the company has said some applications such as food containers are likely a decade away.
