The company experienced rapid growth but then encountered “supply chain challenges”, the letter said.
In 2021, Manta5 chief executive Mark Robotham said the firm had just closed “a $2m top-up round”.
It had sold more than 400 units of its $12,990 Hydrofoiler XE-1 aquabikes, generating some $5m in revenue, but faced ongoing supply chain issues related to the pandemic.
Large orders from hire operators could not be filled - or at least, not for months.
A plan to raise a further $6m then list on the ASX within 12 to 18 months never eventuated.
The firm had already cut staff and ceased promotional activity, the April 16 letter said.
“Yet these measures were insufficient to mitigate our financial strain,” the letter added.
In his 2021 interview, Robotham said Manta5 had 25 staff in New Zealand, two in China and four in Europe. The staff were focussed on R&D and sales The firm worked with contract manufacturers in China, Taiwan and Malaysia.
Torpedo7 founders’ new venture
Manta5 was founded by Guy Howard-Willis with his son Luke.
The pair earlier founded the outdoor goods website Torpedo7 and daily-deal site 1-Day, both of which were acquired by The Warehouse Group in 2016 in a $65m deal (earlier this year, Torpedo7 was onsold for $1).
The father and son still hold a majority stake.
Howard-Willis first had the idea for a hydrofoil bike using a combination of pedal and electric motor power in 2010.
It was first put on the market nearly a decade later.
Manta5′s bikes were an eco-friendly alternative to a jetski, but also expensive and physically exerting - if you stopped pedalling, you would struggle to stay upright if there was any chop.
Although some deals have still got over the line, venture capital has tightened considerably in the era of higher interest rates.
The administrators and Howard-Willis have been approached for comment.
