Funding twelve months of evidence, IP and first revenue.

We are early-stage with in-vitro proof of concept, no filed IP and no product on the market. This page says exactly what stage we are at and what the money buys.

Growth curve from IP filing through in-vivo data to first revenue
01 ·The case

Why this, why now.

A billion-dollar phytogenic category is growing at about 6% a year, with antimicrobial replacement already a leading application13. Regulation is also reducing routine antibiotic use in key export markets10.

Livestock antibiotic use is still projected to rise almost 30% by 20402, while AMR action is modelled to return US$28 for every US$1 invested6.

Green Antibiotics combines reproducible in-vitro leads with a twelve-month plan to filed IP, live-bird evidence and first revenue.

Position, stated plainly

Where we are not yet

  • No patent applications filed. Filing is the first use of funds.
  • No in-vivo efficacy, toxicology or residue data.
  • No product authorised for sale in any jurisdiction.
  • No revenue and no commercial agreements in force.
  • Regulatory classification not yet confirmed with advisers.
  • Screening data not yet peer reviewed or independently replicated.
02 ·Use of funds

What the round pays for.

Indicative allocation. Final figures are in the investor pack.

One

Intellectual property

Prior-art work and priority patent filings before further disclosure.

Two

Laboratory programme

MIC/MBC, resistance, mechanism, safety and independent verification.

Three

In-vivo poultry study

One controlled broiler trial designed to EFSA data standards.

Four

Manufacture & QC

CMO batches, potency assay, stability and controlled sourcing.

Five

Regulatory strategy

Classification advice for Bangladesh, UK and EU pathways.

Six

Team

Add animal-health regulatory and commercial execution capability.

03 ·Risk factors

What could go wrong.

Every early-stage investment carries risk. These are the specific ones here.

Risk

In-vitro may not translate

Agar activity may not reproduce in a live bird; the broiler study is the first gate.

Risk

No IP filed yet

The combinations stay unprotected until priority patent applications are filed.

Risk

Classification unconfirmed

Classification sets dossier scope, cost and timeline differently in each market.

Risk

Raw material variability

Botanical potency must be controlled across harvests, suppliers and extraction batches.

Risk

Well-capitalised rivals

Large incumbents hold the distribution; our differentiation has to be stronger evidence.

Risk

A possible efficacy ceiling

Phytogenics may lose efficacy under heavy challenge; cocktails must close the gap.12

04 ·Risk mitigation

How each of those risks is being closed.

Listing risks is easy. What matters to an investor is whether the plan retires them in a defined order, at a defined cost, with people who have done it before. Every mitigation below maps to a funded, dated deliverable in the twelve-month plan.

Mitigating · in-vitro may not translate

De-risk biology first

Run the live-bird study early; published work already supports this compound class in poultry.18

Mitigating · no IP filed

File before major spend

File priority patent applications before any further disclosure, publication or partner discussion.

Mitigating · regulatory classification

Keep two regulatory tracks

Confirm classification early and run the fast regional route beside the EFSA dossier.

Mitigating · raw material variability

Standardise the raw materials

Control botanical variability through potency specifications and a formal stability programme.17

Mitigating · well-capitalised competition

Compete on stronger evidence

Compete on named-pathogen, resistant-isolate evidence that the large brands do not publish.

Mitigating · efficacy ceiling

Use the combination advantage

Multi-compound synergy is supported by published poultry work and our own screening.19

05 ·Capital efficiency

Why this round is small, and deliberately so.

The round buys four re-rating milestones: filed IP, MIC data, resistance testing and one controlled poultry study.

Bangladesh operations provide a lower-cost base in the highest-burden AMR region1, while the UK company holds IP and the international regulatory pathway.

  • Each tranche funds one defined milestone.
  • Track A targets revenue before the next raise.
  • Studies are designed once to the higher standard.
  • Partners carry distribution build-out costs.
  • IP, assay expansion and poultry validation come first.
  • Every work package has a clear stop-or-go gate.
Execution risk — the one investors ask about last

This team has already done this once

Avix has already moved T-Booster from laboratory concept through a completed 260-volunteer human study, manufacturing coordination and commercial preparation.

Dr David Brown adds senior discovery experience, Viagra co-invention, Relpax contribution and the published resistance-breaker concept5.

  • One product already taken from concept to completed human study.
  • Twenty-four staff across eleven disciplines already in post.
  • UK company holds the IP; Bangladesh operations hold the cost base.
