This means huge scale and impact: capable of supplying to a global economy hungry for raw materials that are carbon neutral, non-toxic, and marine biodegradable. The end result: stronger and low-carbon economies.We’ve developed a proprietary model for a ‘cascading’ biorefinery, which means we’ve engineered each step of our production sequence to create products and derivatives with minimal waste, energy use, or additional effort – hence the cascade to create a range of products for agriculture, textiles, personal care and cosmetics. This wide variety of raw materials and products for agriculture, textiles, personal care and cosmetics crafted from excess seaweed waste allows for us to touch a vast range of markets and partner with recognizable companies to deliver high quality products you may soon find in your own home. The positive environmental impact of our biodegradable and carbon neutral products includes happen to be biodegradable and carbon neutral actually help reduce and offset emissions from fossil fuels and traditional plastics non-recyclable materials, while minimizing waste. Our ProductsThere is an increasing quantity of this valuable resource literally laying on beaches or taken to rot in landfills, and C-Combinator is the one who has figured out how to take the Sargassum and make valuable products out of it. We have been working with local governments and resorts to form contracts where they actually pay us to remove the Sargassum. It's a tremendous advantage to have a company built on a near-zero cost of goods, and we are looking at incredibly high margins of up to 70%. We have generated to $80,000 since mid-March 2021 launch, securing our negative raw material cost.\u0026nbsp;Our Team\u0026nbsp; As a company leading the way in the next-generation sustainable economy, we’ve assembled a global team of experts representing the United States, Puerto Rico, Mexico, Germany, and more. It is through our team's multi-disciplinary expertise that we are able to understand the scope of the Sargassum emergency, the role humanity plays in creating it, and how we can harness the power of this brown seaweed to close the circular economy and benefit communities around the world, starting in the Atlantic and Caribbean.

I hope these answers are helpful: 1) Our convertible notes technically have a cap of $29M but that was an investor that requested that number. Our Series A round will be at $15M, we tried to clarify that but the cap needs to be published on here. $15M is the pre-money into which we anticipate these notes converting, and at a 15% discount.

Our IP filing covers a proprietary method of extracting the valuable alginate that protects the long chain molecules that make it excellent for emulsifiers and leather. I obviously can't disclose more than that, but we are filing more process IP on our entire production chain, more on the individual extraction steps, the steps to make our products, and the products themselves.

If the Series A will be at a $15M cap, why not just wait for that and invest then? Why buy in at double the valuation at an earlier time?","answer":"Hi Robert, Thanks for the question. The $29M is a valuation cap which sets a ceiling on the valuation the note investment converts into equity at the Series A (we expect to close late summer). Our Series A is priced at $15M, so the note will convert at a 15% discount to the $15M valuation. The cap was set last year to protect convertible note investors from a high Series A valuation.
