As of 1 September 2021, we have invested in four exciting ocean impact start-ups.

Plan Blue German Ocean tech start-up is pioneering the use of hyper-spectral imaging to build a global seafloor database with underwater satellites

This German ocean tech start-up is pioneering the use of hyper-spectral imaging to build a global seafloor database with underwater satellites. Lynton is an investor and advisory board member and has been working with Planblue since 2019 to raise capital and scale and commercialise their proprietary technology globally. The initial investment raise was well supported by European angel and VC investors. A second fundraising round of €1.5M is now open. Get in contact for more information.

Shark Safe Barrier

Venture4th is a shareholder of, and advisor to, this innovative start-up behind the award-winning technology that combines magnetic and visual stimuli to deter shark species considered dangerous to humans. Spun out of Stellenbosch University in South Africa, the company has patented technology that works to keep people safe from sharks while simultaneously protecting the sharks. The company is seeking investment in the order of $300k, in exchange for equity, to roll out its global business plan.

Venture4th has invested in this early-stage startup which is working to address the problem of land-borne ocean-bound waste plastic, by designing and manufacturing durable, high-quality street furniture. The company is particularly interested in re-purposing discarded cigarette butts and is pioneering a closed-loop solution to deal with this difficult problem. Ocean-i is seeking $200k in seed capital to execute its commercialisation plans. Contact Lynton for more information.
