The problem

Sourcing from China shouldn't feel like a gamble

The opportunity is real — so are the ways it goes wrong. Four failure modes we see overseas buyers hit again and again:

~30%

The "factory" that isn't one

A large share of "manufacturers" on B2B platforms are actually trading companies. Every hidden middleman adds margin, delay, and opacity — and you usually find out after the deposit.

EN ≠ CN

The English web is only the tip

The real supplier universe lives in Chinese: domestic B2B platforms, industry-cluster directories, corporate registries. If your search starts in English, you see the fraction that markets to foreigners — not the fraction that's best at making your product.

0

A gold badge is not an audit

Platform badges are purchased marketing, not verification. Registration status, real headcount, export history, lawsuits and abnormal-operation flags are all checkable — if you can read the official sources.

12h

Quality drift across 12 time zones

Great samples, rushed mass production, slow replies while you sleep. By the time the problem surfaces, the container is already on the water — and returns to China are nearly impossible.

What we do for you

One team from spec to shipment

Take the whole pipeline, or just the stage you're stuck on. Every engagement is documented, data-backed, and shown to you.

🛰️

Supplier Discovery

AI agents sweep Chinese B2B platforms, industry-cluster directories, exhibitor lists and corporate registries — hundreds of candidates, deduped and classified into a structured longlist.

🛡️

Verification & Factory Audit

Registry cross-checks plus on-site or structured video audits of equipment, lines, QC process and compliance — with a clear proceed / proceed-with-conditions / stop recommendation.

⚖️

RFQ & Quote Normalization

Bilingual RFQs; quotations normalized to the same spec, quantity breaks and Incoterms (EXW / FOB / DDP) — outliers, missing tooling costs and unrealistic lead times flagged.

📦

Sampling Management

Sample rounds coordinated, every revision tracked against the written spec, and the approved golden sample locked in as the production reference.

🔬

Production Monitoring & QC

In-line and pre-shipment inspections with photo reports at every checkpoint. The final balance doesn't move until the PSI passes.

🚢

Logistics & Consolidation

Multi-factory consolidation, container planning, freight coordination and the export document pack — commercial invoice, packing list, bill of lading.

The engine

Six steps. AI does the sweep, humans do the handshake.

This is where being an AI company actually matters. Each step below shows exactly what our agents do, what our people do, and what lands in your inbox.

1

Requirement Intake

From napkin sketch to machine-readable spec

Send drawings, photos, a competitor link — or just a description of what you're trying to buy.

🤖 AI does
Structures your input into a bilingual specification: materials, dimensions, tolerances, certifications (CE / FDA / RoHS), target price band, MOQ range — the format Chinese factories actually quote against.
🧑 On the ground
A sourcing lead resolves ambiguities with you in one focused call, not twenty emails across time zones.
YOU GET A sourcing brief both sides sign off on — the yardstick every later step is measured against.
2

AI Supplier Sweep

Search the market foreigners can't see

The best factory for your product often has zero English marketing. Our agents go where they actually are.

🤖 AI does
Crawls Chinese-language sources — domestic B2B platforms, industry-cluster directories, trade-fair exhibitor lists, corporate registries — and builds a longlist of hundreds of candidates, deduped and classified by capability.
🧑 On the ground
We apply cluster knowledge: which town actually makes your product, and which industrial belt to skip.
YOU GET A structured longlist with a source link for every candidate — no black box.
3

Cross-Verification & Scoring

Data first, promises second

This is the step that kills ghost factories and trading companies posing as manufacturers.

🤖 AI does
Checks every candidate against 60+ dimensions of official records — registered capital, social-insurance headcount (the real factory size), import/export credit records, legal disputes, abnormal-operation flags, factory-vs-trader classification — then scores each against your spec.
🧑 On the ground
An analyst reviews every flag. Anything ambiguous gets a phone call in Chinese — factories answer questions differently in their own language.
YOU GET A scored shortlist of 3–5 factories, with a comparison matrix and the evidence behind every score.
4

RFQ & Quote Normalization

Apples to apples, finally

A $2.10 EXW quote and a $2.60 DDP quote say nothing until they're on the same terms.

🤖 AI does
Drafts the bilingual RFQ, collects quotations, normalizes them to the same spec, quantity breaks and Incoterms — and flags outliers, missing tooling costs and lead times that don't survive scrutiny.
🧑 On the ground
We negotiate in Chinese, in the factory's time zone, with the leverage of twenty alternatives behind us.
YOU GET One comparison table you can actually decide on.
5

Samples & Factory Audit

Trust, then verify in person

Paper verification gets a factory to the shortlist. Only a physical visit gets it to your order.

🤖 AI does
Tracks sample rounds, revisions and courier status against the spec; pre-processes audit photos and checklists so the auditor's time goes to judgment, not paperwork.
🧑 On the ground
Our auditor visits the factory — equipment, production lines, QC process, working conditions — or runs a structured video audit when speed matters more.
YOU GET An audit report within 72 hours — proceed, proceed with conditions, or stop — plus the approved golden sample.
6

Production, QC & Logistics

Your eyes in the factory until it ships

Quality drift is a monitoring problem. We instrument it instead of hoping.

🤖 AI does
Monitors production milestones, schedules inspections, drafts the export document pack (commercial invoice, packing list, bill of lading), and escalates deviations the day they appear.
🧑 On the ground
In-line and pre-shipment inspections with photo reports. Consolidation and freight coordinated to your door. The final balance doesn't move until PSI passes.
YOU GET Inspection reports at every checkpoint — and a shipment that matches the sample you approved.
Why us

We're an AI company that runs a sourcing practice — not a trading company with a website

Mostar builds production AI agents for a living. The same machinery that runs our own business runs your sourcing.

30+

AI agents in production

Our agent fleet runs real operations for us every day — marketing, lead generation, data collection, quality control — across a dozen machines and 45+ scheduled daily jobs. Sourcing plugs into machinery that already works, not a demo.

60+

Official-record dimensions per factory

Registered capital, social-insurance headcount, import/export credit, litigation, abnormal-operation flags, foreign-investment status — the screening depth our own lead-generation pipelines use daily, pointed at your supplier list.

中文

We read the Chinese internet natively

Registries, domestic B2B platforms, customs data, local directories — the data layer underneath the English web. That's where the factories you never find actually live.

AI + 人

Human where it matters

Agents do the sweep, the cross-checks and the paperwork. People do audits, negotiation and judgment calls. You get machine coverage with human accountability — and every claim arrives with its evidence attached.

Straight talk: AI makes the search wide, fast and evidence-backed. It does not replace standing on a factory floor. That's why every engagement pairs the two — and why we'll tell you within the first conversation if your category or volume isn't a fit for how we work.
The honest comparison

Three ways to source from China

DIY on B2B platforms Traditional sourcing agent Mostar: AI + on the ground
Candidate pool Whoever markets in English Their existing Rolodex The whole Chinese supplier universe, swept by agents
Verification Paid badges & self-declaration Varies — sometimes a visit 60+ official-record dimensions plus on-site audit
Quote comparison Your own spreadsheet, mismatched terms Often opaque — commission baked in Normalized to the same spec & Incoterms, itemized, shown to you
Speed to shortlist Weeks of inbox ping-pong Typically 2–4 weeks Days for the AI sweep; audit scheduled the same week
Transparency None — you're the verification department "Trust us" Every shortlist ships with the evidence behind each score
Getting started

Start with one product line

No retainer required to start the conversation. Prove the process on a single SKU or category before you scale.

STEP 01

Send your spec

Drawings, photos, a competitor link, or a plain-English description of what you're trying to buy. Two minutes is enough to start.

STEP 02

Get an initial read

We come back with a first assessment: realistic price bands, the likely manufacturing clusters, the MOQ landscape — and a straight answer on whether we're the right tool for it.

STEP 03

Pilot, then scale

Run one sourcing cycle end to end — longlist, scores, quotes, audit, samples. You see every artifact. Scale only if the evidence earns it.

FAQ

Questions buyers ask us

Are you a trading company?
No. We don't take ownership of goods, and we never hide the factory from you — you know exactly who makes your product. We run discovery, verification and coordination as your team on the ground in China. Our incentives stay aligned with yours because our margin isn't hidden inside the factory's price.
What product categories do you cover?
Manufactured goods with definable specifications: consumer products, packaging, components, light industrial and more. If your category carries heavy regulatory certification (medical, food-contact, children's safety), we'll tell you upfront what that involves before any engagement.
Our order quantity is small. Is this still worth it?
Often, yes. MOQs are far more negotiable when you can talk to twenty factories instead of three — and the AI sweep is exactly what makes a wide search economical for smaller orders. If your volume genuinely doesn't justify the process, we'll say so in the first reply.
How do you charge?
Scoped per engagement: discovery-to-shortlist only, or end-to-end through production, inspection and delivery. We quote after reading your spec — no retainer is required to start the conversation.
How is our intellectual property protected?
NNN agreements (non-disclosure, non-use, non-circumvention) are signed before any drawings move. Your specification is shared with shortlisted factories only, and in stages — never broadcast.
Where is your team located?
Shanghai, China — Minhang District AI Demonstration Base. The manufacturing clusters of the Yangtze and Pearl River Deltas are a train ride away, not an international flight. That's the whole point.

Tell us what you're trying to source.

Send your spec — drawings, photos, or a competitor link. You'll hear back from a human, with data attached.
