The Blob 100

The 100 most interesting companies in algae, according to The Blob

The Blob has been around for almost exactly a year now (first “Hello World” post was 01/10/25), averaging about one deep-dive post a month since January 2025.

For the end of the year, I’m going to do something a little different, somewhat seasonal. It’s, of course, a list.

Below you will find a completely subjective, non-exhaustive, unranked, alphabetical mixer of the 100 companies in algae (micro and macro) that I find personally interesting. I hope you do too 🖖🏼.

I haven’t listed any companies that are explicitly focused on biofuels, energy production, or marine carbon dioxide removal/carbon capture. Make of that what you will. I was also tempted, but ultimately chose not to include any academic institutions, government organizations/funding sources, investment firms, accelerators, or consulting firms.

What you will find are companies that are cultivating, harvesting, and selling algae and/or algae-based products, as well as the companies that provide the platforms, technologies, and systems to do so.

I would love to follow up on this list next year to see how these teams are doing and update it with fresh successes. Here, too, are a few types of companies I’d like to add for next year/ in the future (attention builders!):

• Specialty harvesting vessels / attachments

• Algae-based wound care products

• Built environment/specialty polyurethanes for thermal or acoustic functions

• Algae drug delivery platforms

• Farmer cooperative/collective logistics platforms

• Algae-based commercial adhesives

• Underwater seaweed aquaculture monitoring

• Algae-based marine sealants

• Luxury hydrotherapy

• Algae tattoo ink

In the meantime, enjoy the films, fats, foams, foods, photobioreactors, and bioplastics that make up the bulk of the 2025 Blob 100!

59. North Sea Farmers (NSF1) Netherlands (🇳🇱)

Technically a project of the European Seaweed Association, North Sea Farm #1 is the world’s first commercial seaweed farm built inside an offshore wind farm. It’s early days, and not earth-shattering yields, but it’s a big deal. It’s a real-world test of scaling seaweed between turbines to produce food, materials, and climate benefits while boosting biodiversity and proving offshore co-use actually works.

60. Notpla England (🏴󠁧󠁢󠁥󠁮󠁧󠁿)

One of the pioneers of commercial plastic alternatives, it’s been exciting to watch Notpla move from marathon waterball to HRH Prince William as a booster and stadium partnerships.
