Building a physical product is 30% design, 30% manufacturing, 40% getting the manufacturer to actually make the thing you designed. AI helps with the first 30%, partially with the second 30%, and almost nothing with the third 30%. Here's how we used it for Stashed, and where it broke.
Step 1: research (AI: 10x).
Prompt Claude: "Find me 20 bag manufacturers in Tamil Nadu, Karnataka, and Maharashtra. For each, give me: (1) primary product category, (2) past clients if known, (3) MOQ, (4) lead time, (5) location, (6) any quality certifications. Format as a CSV." 4 minutes later: 20 entries, ranked. Would have taken me 3 weeks by hand.
Then: cross-reference with IndiaMart, TradeIndia, and LinkedIn for the top 10. Cross-check 5 of them against the AI's claims. 4 out of 5 accurate. The 1 wrong: a manufacturer that closed in 2024. AI's data was 6 months stale, but I asked it to date-stamp its sources, so I knew to recheck.
Step 2: outreach (AI: 5x).
For the 12 most promising, Claude drafted a personalized first email. Not a template — a real email that mentioned the manufacturer's specialty, my specific product, and a clear ask (send samples, quote MOQ). I edited 8 of the 12, sent 10, got 8 responses. 4 said "send us your spec sheet", 4 said "we don't do custom under 500 units". Down to 8 candidates.
Without AI: I'd have sent 4 templated emails, got 1 response, started the project with a poor manufacturer. With AI: I had 8 candidates by Friday.
Step 3: sample evaluation (AI: 2x).
Asked 4 of the 8 for samples. Got samples from 4 within 2-3 weeks. Evaluated each on: material quality, stitch quality, finish, weight, zipper smoothness, water resistance, value. The AI helped me write a 12-point sample evaluation checklist and weighted the criteria. But the actual hands-on evaluation? Human. I had to feel the bags, run the zippers, pour water on them.
Sample 1: 90% right, Velcro failed in humidity (caught by the stress test). Sample 2: 95% right but 30% more expensive. Sample 3: 70% right, looked like a duffel. Sample 4: 98% right, this is SN Bags (ours). Decision: SN Bags. The AI's checklist helped me evaluate but the choice was gut.
Step 4: negotiation (AI: 1x).
AI is bad at negotiation. It gives you scripts, talking points, what to ask for. But Indian manufacturing negotiations are relational, not transactional. The 12% price drop came when Mr. Singh (Nav's dad) joined the call. Family reputation matters. AI can't replicate that.
The lessons, summarized.
AI is a 10x multiplier on research and outreach. A 2x multiplier on sample evaluation. A 1x multiplier (i.e., human-only) on negotiation. Use it for the first 60%, do the last 40% yourself. The full Stashed case study is at /stashed-case-study.
