Pre-Seed Investment · Ocean-Tech

Turning the ocean's greatest nuisance into its greatest resource.

The ocean grows our feedstock for free. We get paid to collect it - then sell it three times over. Plastic Twin transforms invasive sargassum into a cascading matrix of high-value products, scaling into the world's leading producer of ocean-degradable single-use packaging.

Three Problems · One Solution

One invasive bloom sits at the center of three multi-billion-dollar problems.

Sargassum $300M+ Annual cleanup · 30+ nations

The Great Atlantic Belt spans 8,000+ km, inundating 30+ nations - driving billions in cumulative tourism and cleanup losses. Biomass up 5× since 2011.

Agri Runoff $157B Annual US Cost

The US cost of synthetic fertilizer runoff - the very nitrogen and phosphorus pollution our biostimulants displace.

Plastic 14Mt Annual Ocean Influx

PLA and PHA don't biodegrade in seawater. Our alginate does - at negative feedstock cost.

Three-Product Biorefinery

One feedstock. Three revenue streams. Each more valuable than the last.

Year 1

Biostimulant

$4K-$7K / tonne liquid extract

OMRI organic. FL citrus, nurseries, golf turf, regenerative ag. $4.5B and growing at 12% CAGR - the market we enter in Year 1.

Year 2

Sodium Alginate

$8K-15K/t food · $3K-6K/t industrial

Food, pharma/wound care, textile printing, dental. ~$1B global market. ~5-6% CAGR.

Years 3-4

Alginate Bioplastics

$15K-$60K per tonne

Ocean-degradable films, polybags, and single-use packaging. Apparel, e-commerce, and food service sectors. $18B global market growing at 19% CAGR.

Revenue Engine

Biostimulant revenue de-risks early operations while we build toward bioplastics at scale.

Competitive Landscape

Company	Free Feedstock	Atlantic	Product Lines
Plastic Twin	✓ Paid to take	✓ First Mover	✓ Three
Carbonwave	Partial	Puerto Rico only	Partial
Notpla	✗ Purchased	✗ No	Single line
BASF / Syngenta	✗ Purchased	N/A	Single line

Premium competitors pay $300-$800/dry tonne for farmed seaweed. Notpla and others purchase alginate - we produce from sargassum at negative feedstock cost.

The Unfair Moat

Cost Leadership

Paid to take feedstock - structural advantage no farmed-seaweed competitor can match.

First Mover

First commercial sargassum biorefinery in the continental US producing certified agricultural biostimulants.

Ocean Narrative

Every kg removed earns brand premium and unlocks $1M+ in exclusive non-dilutive grants.

<2 ppm

Process Tech · Hot water + citric acid treatment reduces inorganic arsenic from ~60-90 ppm to <2 ppm - within all applicable regulatory limits (FDACS, EU, OMRI).

IP Strategy

Developing proprietary formulations and exclusive supply agreements to build a defensible supply-chain moat.

Raising Now · We're currently raising a $50K MVP tranche to prove the processing protocol and secure first customer commitments before closing the full $1M round.

Now · Q2 '26 MVP tranche open · NSF SBIR submission underway · Miami operations scoped 2-5

Q3-Q4 '26 Biostimulant toll-manufacturing line live · First batch · CoA · First sale 5-10

Q1-Q2 '27 Commercial batches · OMRI cert · Alginate MVP to brand partners 10-20

Q3 '27 $5K-$15K MRR · Sodium alginate line live · First food-grade PO · Seed round opens 20-40

2028-29 Recurring commercial volume · In-house bioplastics pilot · Series A 40-150

2030+ Vertical integration · Caribbean expansion · Largest seaweed bioplastics producer 500+

Vision · 2031+ Giant kelp permaculture operations online · Owned year-round feedstock · Full vertical integration · Climate-resilient supply chain 1,000+

The Long-Term Vision

Long-term, we own our feedstock entirely through giant kelp permaculture - eliminating seasonal dependency and creating living ocean infrastructure that sequesters carbon and restores marine ecosystems.

Use of Funds $1.0M

15-mo runway · Deliver Phase 1 commercial revenue and secure Phase 2 off-take agreements.

Commercial Batch Production$350K · 35%

Hybrid model: Homestead handles feedstock prep + arsenic removal; toll-manufacturing partners run extraction & formulation through Yr 1, transitioning in-house in Yr 2 as volume justifies CapEx.
