Market Research & Product Strategy
Before formulation begins, we help founders understand what's commercially
viable — not just what's scientifically interesting.
Why it matters
Most product mistakes are positioning mistakes. The right research phase can save 3– 6 months of rework.
- Market & competitive landscape analysis
- Format & manufacturing recommendations
- Pricing & margin feasibility review
- Identifying gaps & market differentiation
Founders who skip this step are 3× more likely to reformulate post-launch.

Supplement Formulation
We support formulation across human and pet supplements, with a strong focus
on efficacy, compliance, and commercial viability.
Why it matters
Formula decisions lock in your cost structure, your claims, and your manufacturer
options. Getting it right first time is critical.
- Compliant ingredient sourcing & dosing
- Compliance-ready formats (UK, EU, US)
- Cost-reviewed finalised formula spec
- Bioavailable format, flavour & coating options
Formulas reviewed for compliance before, not after, production begins.

Supplier Sourcing & Manufacturing
Our network of vetted UK, EU, and US manufacturers is built through 150+
sourcing projects — not cold outreach.
Why it matters
Unreliable manufacturers are the most common cause of delayed launches and costly
recalls. Our relationships are built on track record.
- MOQ, pricing & lead time negotiations
- GMP, policy & shelf-life representation checks
- Sample coordination & comparative evaluation
- Direct supplier communication & production setup
Prioritise fit, reliability & long-term ability when introducing suppliers.

Amazon, DTC, and TikTok-first channels.
Why it matters

— never aesthetics alone.

- TikTok-native creative assets
- Product page copy & compliance alignment
- Packaging supply chain & print sourcing
Compliant, conversion-focused creative delivered in one coordinated workflow.

Shopify Builds & Launch Infrastructure
For brands ready to sell, we support the technical foundations required to launch
on Shopify DTC and retail channels.
Why it matters
A slow or confusing storefront kills conversion before your product gets a chance. We
focus on functionality, clarity, and speed.
- Shopify store build & theme setup
- Product detail page structure & copy
- Shopify payments & fulfilment
The focus is functionality, clarity, and conversion — not unnecessary complexity.
Enquire about this service
Compliance Support
Compliance is embedded throughout the build process, not added at the end.
We support product claims and label alignment throughout.
Why it matters
Non-compliant labels can prevent retail listings, Amazon approvals, and even product
recalls. Building compliance in from day one eliminates this risk.
- Compliant label alignment
- Legal and packaging structure review
- Market-specific compliance: UK, EU, US
- Key claims and disclaimer positioning
This helps prevent relabelling, reformulation, or delayed launches.

How engagements are scoped.
No rigid retainers. Every engagement starts with a scoping conversation to define what's actually needed.
Work can be phased as your brand evolves.

- Clear brief and defined output
- Typically 2–4 week turnaround
- Can extend into broader engagement if needed
End-to-End Build
Best for
Founders building a new supplement brand from scratch who want one partner to manage the full process — strategy through launch.

- Single senior lead throughout
- 16–20 week average timeline
- Bi-weekly check-ins & stage-gate summaries
- Post-launch reorder support included
Ongoing Advisory
Best for
Established brands that need a strategic partner for reorders, reformulations, new market entry, or range extensions — without a full new build.
