Who this is for
Most founders come to us
at one of three stages.
Wherever you are, we scope the engagement to meet you there — no rigid packages, no wasted spend.
Clarity
You have a product idea but need help validating it, finding the right format, and understanding what's commercially viable before committing.
This sounds like meExecution
You know what you want to build. You need an experienced partner to source,manufacture, and manage compliance — end to end.
This sounds like meLaunch or expansion
You're already selling and need to reformulate, expand to new markets, or scaleproduction without quality issues or supplier headaches.
This sounds like meHow it works
From first call to live product.
Every CJK engagement follows the same structured path — so you always know what stage you're in, what's being handled, and what comes next. No guesswork, no black boxes.
Strategy
Discovery Call
A focused 60-minute conversation to understand your brand vision, target market, budget, and commercial goals. We ask the questions most founders overlook early — helping avoid costly delays and rework later on.

Strategy
Product & Market Strategy
We map the market opportunity, define your product positioning, identify the right format, and flag any regulatory considerations for your target market — before a single ingredient is sourced or a supplier is contacted.
Weeks 1–2
BRANDING
Brand Design & Identity
We develop your brand identity, packaging design, and label compliance in parallel, so your visual assets are ready when needed — helping avoid unnecessary delays. Includes compliance-aware label copy, regulatory claims review, print-ready artwork, plus professional renders and infographics. Product photography available as an add-on.

Development
Formula Development & Sampling
Our in-house formulation chemists, pharmacists, and vets develop your product spec based on the brief. We manage suppliers, compare quotes, validate quality, and coordinate samples, so you get clear recommendations, not endless supplier emails.
Weeks 2–10
Operations
Manufacturing & Quality Control
Full production run managed end to end. We track production milestones and quality checkpoints with the manufacturer so you're never chasing factories directly or decoding technical back-and-forth across time zones.
Weeks 8–16

Operations
Packaging, Compliance & Logistics
We produce compliance-aware labels built to the regulations of your target market, and can issue a certificate of compliance for your product (optional add-on). We then connect you with trusted fulfilment and shipping partners, so your product arrives on time, on spec, and shelf-ready.
Weeks 10–20
SUPPORT
Pre-Launch & Store Build
While your product is in production, we build your entire launch infrastructure - validation lander, full Shopify store, Klaviyo email flows, and tested Meta ad creative. So the day your stock lands, everything is already running. Available as a standalone service via the CJK Launch Engine.

What you can expect
Why founders choose a structured process.
The biggest mistakes in supplement brand building come from fragmented execution. CJK centralises everything — so less falls through the cracks.
Clear milestones, always
You'll always know what stage you're at, what's been completed, and what the nextdecision point is.
Compliance built in, not bolted on
Regulatory review happens during development, not after production, when changesare expensive.
One person, full accountability
A single CJK lead owns your project. No handoffs, no chasing multiple contacts, nodropped context.
Realistic timelines, upfront
We tell you how long things take before you commit - not optimistic estimates thatslip under pressure.
Fewer supplier headaches
We handle all manufacturer communication so you never have to chase factories orinterpret technical back-and-forth.
BOUNDARIES & FIT
What we don't do.
Because how we work matters just as much as what we deliver. We’re best suited to brands looking for thoughtful, commercially grounded decisions.
False Guarantees
We can’t promise your product will sell. We focus on giving you a validated, compliant, and well-made foundation to launch from.
Cheap Over Quality
We won’t recommend low-cost suppliers if quality or compliance suffers. Short-term savings often create bigger problems later.
Cut Corners
If a timeline isn’t realistic, we’ll say so. We don’t skip testing, sampling, or compliance to rush production.
Unnecessary Complexity
Every ingredient should serve a commercial purpose — not just make the formula look more advanced.
Forced Services
If advisory support is enough, we won’t push full execution. We recommend what fits your stage and goals best.
We’re best suited to brands looking for thoughtful, commercially grounded decisions.
If you’re still exploring or unsure, we’re happy to have an honest conversation either way.
