For DTC brands $500K–$10M with no supplement line yet

You paid for the customer your competitor is keeping.

We add a supplement SKU to the catalog you already run — formulated to your brief, manufactured to tier-one spec, on your shelf in 30 days. You keep your store, your team, your traffic. We handle the product.

Your cohort data already shows the gap.

Pull the last 90 days of repeat buyers. Run a quick check on what they're buying outside your store. If you're in fitness, apparel, wellness, recovery, or outdoor, the answer is already obvious — they're buying creatine, protein, collagen, or nootropics every month. They're just not buying it from you. That's not a CAC problem. It's a catalog problem.

1Your CAC is already paid — you acquired the customer. The supplement spend is recurring, monthly, and currently funding someone else's P&L while yours flatlines.
2Your trust is already built — the next product through their cart is the easiest dollar you'll ever make. They don't need to be sold on you again.
3The infrastructure you already run handles it — same Shopify, same 3PL, same email list, same ad account. One new SKU. Not a new business. Not a new team. Not a new headache.
How the system moves

A straighter path from call to shelf.

Phase 01

Strategy call · Day 0–2

Twenty minutes. We look at your customer profile, your existing AOV, and what your buyers are purchasing outside your store. You leave the call with a recommended SKU, target unit economics, and a real timeline. No quote-before-discovery games.

Phase 02

Formulation & samples · Day 3–14

Custom formulation built to your brief — dose, format, flavor, label claims. Samples in your hands inside two weeks. You taste it, your team tastes it, you reformulate as many times as you want. That cycle is on us, not you.

Phase 03

Manufacturing · Day 15–28

Tier-one production. Full COA per batch. Allergen-controlled lines. Freight, customs, and insurance handled. You get weekly progress. Off-spec runs are our problem — we re-run, you don't eat inventory.

Phase 04

On your shelf · Day 30

Inventory lands at your 3PL. You list it in your own store, your own funnel, your own subscription flow. We re-run on your forecast. You hit reorder, we ship in 21 days. You never stock out on the SKU funding your AOV lift.

What you get

What you actually get when you bring on a manufacturing partner.

One vendor, one PO, one invoice. The product, the compliance, the supply chain — held together by us. You handle the customer. We handle the shelf.

Custom formulation, your IP

Your formula, your dose, your label claims. You own it forever. We can't sell it to anyone else, contractually or otherwise.

Tier-one manufacturing

FDA-registered. GMP-certified. Third-party tested. The same facilities producing brands at retail. Compliance you can put in front of retail buyers without flinching.

Pilot-run MOQ

First runs from 1,000 units. Prove the unit economics before you commit to volume. No 50K-unit lock-in to find out if the SKU lands.

Compliant packaging & label

Structure/function claims, allergen statements, and on-pack copy reviewed by FDA-compliance counsel. Ready for DTC, Amazon, and retail out of the box.

End-to-end supply chain

Raw materials, manufacturing, QA, packaging, freight to your 3PL. One vendor. One PO. One invoice. No 4-vendor-coordination nightmare.

Reorder on autopilot

Forecast → PO → ship in 21 days. We hold safety stock against your run rate. You never lose a subscription cohort to a stockout.

Catalog Engine
