Start by turning the product vision into a small set of supplier constraints rather than contacting manufacturers at random. Alicia Scott used three: current knowledge of the ingredient profile she wanted, the ability to create deep shades with strong pigment options, and a low minimum order. She searched an industry directory, reduced a broad candidate list to roughly five, and then contacted those suppliers to test whether each could support the concept. The conversations functioned like a mutual-fit screen: communicate enough to establish capability, observe how the supplier responds, and narrow to one partner. The mechanism protects limited cash while keeping product requirements intact. It also makes comparison easier because every candidate is assessed against the same explicit constraints rather than enthusiasm or price alone.
Origin
Alicia Scott described using CosmeticIndex.com and a three-item checklist to find the manufacturer that helped her begin Range Beauty with a $150 minimum purchase. Extracted from The Foundr Podcast.
Core principles
- 01Define non-negotiables before contacting suppliers
- 02Use directories to widen the initial candidate pool
- 03Share enough of the vision to test capability without oversharing
- 04Treat supplier selection as a mutual-fit process
How to run it
- 1
Define the non-negotiables
Convert the product promise and cash limits into a few supplier requirements. Alicia prioritized ingredient capability, deep-shade pigment options, and small minimum quantities.
Pro tip Keep the list short enough to use as a real filter.
Watch out Do not let a low price compensate for failure on a core product requirement.
- 2
Build a broad candidate pool
Search a specialist directory for manufacturers serving the relevant product category. Capture enough candidates to compare rather than committing to the first plausible result.
Pro tip Use a directory that also identifies adjacent needs such as labs, packaging, and design.
- 3
Filter against the constraints
Remove any supplier that clearly misses a non-negotiable. Reduce the long list to a manageable shortlist for direct conversations.
Watch out Do not quietly relax the checklist merely to preserve a favourite candidate.
- 4
Test capability in conversation
Email or call each shortlisted supplier with a concise version of the vision and ask whether it is within their capabilities. Use both the answer and the quality of the interaction as fit signals.
Pro tip Explain the required outcome without disclosing every detail of the concept.
- 5
Choose the best mutual fit
Compare candidates on all constraints, responsiveness, and willingness to work at the required scale. Begin with the supplier that clears the whole screen.
Pro tip Use the smallest viable initial order to preserve learning capacity.
Watch out A small minimum order does not remove the need to test product quality.
In the wild
Scott searched CosmeticIndex.com, screened manufacturers for the ingredient profile she wanted, deep-shade pigment capability, and small minimum quantities, then spoke with a shortlist. She selected a manufacturer offering a $150 minimum purchase and used the initial materials to begin mixing products at home.
→ She found a supplier she said she continued working with while keeping the initial cash commitment low.
Common mistakes
Searching without criteria
A large supplier directory creates noise unless every candidate is tested against the same product and budget constraints.
Revealing the entire concept immediately
The first contact only needs enough detail to establish whether the supplier can perform the required work.
Is it for you?
Best for
It is best for early physical-product founders who know the product capabilities and budget limits they require.
Not ideal for
It is not ideal for founders who have not yet defined their product requirements or validated that manufacturing is necessary.
