What 200+ Brands Taught Me About Winning on Amazon

Most D2C founders have cracked Instagram. They've got the Shopify store humming, the meta ads dialed in, the ROAS looking decent. But there's this massive commercial opportunity sitting right in front of them that they keep treating as an afterthought: Amazon.

Here's the thing about Amazon that most founders miss. When someone types "organic baby blanket" into that search bar, they're not browsing. They're buying. Credit card saved, Prime membership active, one-click purchase ready. Amazon converts at 10 to 15 percent on average for Prime members and up to 74 percent on peak days. No Shopify store on earth touches those numbers. Yet most founders treat it as a secondary channel.

Nirav knows this better than almost anyone. He started his journey as an Amazon delivery boy in Ahmedabad. Let that sink in. From delivering packages to running Sellers Umbrella, an agency that's worked with over 200 brands and managed more than $5 million in Amazon ad spend. Along the way, he spent nine years at eStoreFactory, one of India's most respected Amazon agencies, learning everything from account management to PPC to cross-marketplace selling. When COVID hit and his second child was born, he stepped out and built his own thing.

His tagline is "growth, not guesswork," and in this conversation, he showed us exactly what that means. From keyword-level budget analysis that saved one brand 31% in wasted spend, to treating inventory planning as an SEO tool, to helping Indian brands sell spirulina at $25-35 per bottle in the US market. This is the Amazon masterclass most founders never get.

Key Takeaways: The Amazon Playbook Nobody Shares

The Platform Mental Model:

• Instagram is for discovery, Shopify is your showroom, Amazon is where buying intent lives
• Amazon converts 10-15% for Prime members, up to 74% on peak days
• The right model is: use all three, not one over the other

The Flywheel That Actually Works:

• PPC drives sales, sales improve organic ranking, better ranking brings free traffic
• If your total ad cost (TCOS) is flat or rising, your flywheel is broken
• Paying for traffic on keywords you already rank #1 for organically is literally buying your own customers

Inventory Is SEO:

• A top-10 product going out of stock for one day drops 28% in rank
• Three days out of stock can mean 80-85% rank drop
• Your demand planning spreadsheet has more impact on ranking than your keyword strategy

Q: You started as an Amazon delivery boy. How did you end up running an agency?

Nirav: Yeah, I was a delivery guy and then I joined eStoreFactory. I learned everything from scratch, from the English to everything. Account management, PPC, listing, working across marketplaces, everything is from eStoreFactory. Then COVID happened and I had my second child. Life needed a different setup. I wasn't able to contribute the way I used to, and they're very growth-oriented people. Rather than wasting their time, I thought I should start something on my own. That's where Sellers Umbrella and Merchant Exporter came in. Entrepreneurship was not in my agenda at all. But the circumstances were such that I had to do it.

🔥 ChaiNet's Hot Take: From delivery boy to agency founder in nine years. The best Amazon education isn't a course, it's touching every part of the machine.

Q: When you started, what did you think would be easy that turned out to be hard?

Nirav: Getting paid. Because I know everything, I'm in this industry for more than nine years, so I thought it's very easy to build something from scratch. But that's not the case. When you have nine years of experience but as an agency you're fairly new, nobody wants to pay an unknown agency. We cleared our home loans, moved to a rented place. Our core principle was we don't want to get a loan to do business. We started from home and that constraint actually helped because it forced us to work harder. We couldn't compete with bigger agencies on reputation. So I started working night shifts to be available in the US time zone from India. The turnaround time and being available on the client's time zone was a big plus. We also fixed proactive communication, inventory reports, ad spending reports, no surprises. After the first six months, all our clients were referrals.

🔥 ChaiNet's Hot Take: Can't compete on reputation? Compete on time zones and hustle. Six months of sleepless nights bought a lifetime of referrals.

Q: What are the key differences between founders who succeed on Amazon versus those who struggle?

Nirav: There's a very thin line. The winners treat Amazon as a data platform, not just a listing platform. The experienced ones always track TCOS, which is total advertisement cost of sales. That's ad spend divided by total revenue, not just ad revenue. A healthy product should be under 5 to 10 percent TCOS declining over time. If it's flat or climbing, your organic flywheel isn't working. More and more sellers don't even know these metrics exist. The other thing I see constantly is founders picking products by looking at competitors on Jungle Scout or Helium 10. Those tools only show you the revenue, not the profit. They don't show expenses, returns, the months of losses before breakeven. You're seeing the highlight reel and thinking it's the full movie.

🔥 ChaiNet's Hot Take: Jungle Scout shows you someone's scoreboard, not their hospital bills. Revenue without profit data is just vanity metrics in a different costume.

Q: A lot of Shark Tank brands treat Amazon as secondary to Shopify. Is that the right mental model?

Nirav: The model is right but the framing is wrong. They're different tools. Instagram is for discovery. People scroll, they might notice you, might not. Shopify is your showroom. People who already know you come to browse. But Amazon is where buying intent lives. Someone typing "organic baby blanket" isn't browsing, they're buying. Their credit card is saved already. Based on data, Amazon converts 10 to 15 percent on average for Prime-eligible products and up to 74 percent on peak days. No Shopify store on earth does that. The right model is Instagram builds your audience, Shopify builds your brand, Amazon builds your revenue. We always suggest using all three.

🔥 ChaiNet's Hot Take: Instagram is the billboard, Shopify is the showroom, Amazon is the cash register. Stop asking which one matters most. They're a chain.

Q: Your tagline is "growth, not guesswork." What are founders guessing that they shouldn't be?

Nirav: Their ad money at the keyword level. Amazon tracks conversion rate per keyword, not just overall. So your product might convert 14% on "organic hair oil" and 3% on "natural health care." The dashboard shows you a blended 9% and it looks fine. But half your budget is working and half is wasted. Here's a real example. A supplement brand doing $180K monthly. We pulled keyword data and found $14,000 a month going to 23 keywords converting under 4%. Meanwhile, their best 8 keywords at 80% conversion were hitting daily budget cap by 2pm. They weren't running their best keywords for a full 24-hour window. We moved the money, same total spend, revenue up by 31% in 60 days. That's what end of guesswork means in practice.

🔥 ChaiNet's Hot Take: Your best keywords are starving by 2pm while your worst keywords feast all day. Same budget, different allocation, 31% more revenue. That's not optimization. That's common sense nobody applies.

Q: You say PPC should be a growth tool, not a crutch. How does the flywheel actually work?

Nirav: We created a flywheel concept. PPC drives sales, sales improve organic ranking, better ranking brings free traffic, and total revenue grows while ad spend stays flat. So TCOS goes down. If it's flat or rising, the flywheel is broken. You're paying for traffic you should be earning. The red flag is when you're ranking first organically but still running paid ads on those keywords. You're buying traffic from your own keyword. Real case: one account spending $42,000 a month with their top three products already ranking first, second, and third. A well-known US detergent company still running aggressive paid on those keywords. We cut those campaigns by 60%, redirected $50,000 to a new product launch, a pack-of-two variation. By end of three months, revenue up 8%, TCOS dropped 13%.

🔥 ChaiNet's Hot Take: Paying for ads on keywords you already own is like buying tickets to your own concert. Redirect that money to launch something new.

Q: How important is inventory planning? You've said it's as important as SEO.

Nirav: We treat inventory as an SEO tool. Your inventory level directly impacts search ranking. The data is clear. A top-10 product going out of stock for one day, 28% rank drop. Three days? Probably 80 to 85 percent. And the recovery isn't instant. Weeks for short stockouts, a month for longer ones. Some competitive categories like beauty, products never fully recover because new products launch every day. The algorithm uses a lookback window of 3 to 365 days. Recent consistent daily sales signal reliability. Stockout patterns signal the opposite. Your demand planning spreadsheet has more impact on ranking than your keyword strategy. More sellers don't see it that way, which is why they keep losing rank for reasons they can't explain.

🔥 ChaiNet's Hot Take: Your inventory spreadsheet is your most important SEO tool. One day out of stock costs you 28% of your rank. No keyword strategy recovers from an empty shelf.

Q: What's the most common pattern you see founders repeating as a mistake?

Nirav: Every seller thinks their product is the best in market. But founders write listings based on how they describe their product, not how customers search. Those are two different things. Titles should be keyword-driven, not brand-focused. Bullet points shouldn't be copy-pasted from the brochure. They need to answer buyer questions. And most importantly, the backend search term field. There's a field where you add search terms that buyers might use. Usually when I audit accounts, those fields are empty. They don't even think it's important. Second pattern is set and forget. List the product, set the budget, check monthly. Amazon moves daily. BSR, keyword ranking, competitor pricing, they go up and down every hour. Third, they're not building reviews. Reviews are your salesperson online. There's a program called Amazon Vine where you give away 30 units and get honest reviews. But sellers deny. "Why should I give 30 units just to give away?" Without reviews, even if I land a buyer on your listing, they won't buy. There's no evidence.

🔥 ChaiNet's Hot Take: Empty backend search terms, monthly check-ins, and zero reviews. That's the Amazon failure starter pack. Fix all three before spending a rupee on ads.

Q: Are fake reviews a real problem? How does Amazon handle them?

Nirav: There are agencies and people who do that, but Amazon catches you in a month or two. They have backend spiders, and now with AI, they flag you instantly. If something suspicious is found, they first block your listing. Then there's back and forth for almost a month to get it back. Your inventory is sitting in a US warehouse the whole time. We only do white hat practices. But some of our sellers have done it in the past and we had to rescue them. Eventually it doesn't work out. There are legitimate ways. There's a "request a review" feature for every order. And if your product is genuinely good, you will get reviews. I understand the temptation when a competitor has 100 reviews and you started in 2025 while they started in 2022. But it'll cost you way more than you think.

🔥 ChaiNet's Hot Take: Fake reviews are a loan with a 10,000% interest rate. You get the short-term boost, but the listing ban costs months and the trust never fully comes back.

Q: You also run Merchant Exporter, helping Indian brands sell in the US. How does that work?

Nirav: Same problem, no one knows this is possible. People think you need a physical office there, tons of certifications. But that's not the case. One of my friends has a nutraceutical brand selling spirulina at 500 rupees a bottle in India. On Amazon US, comparable products go for $25 to $35. We did everything. Export documents, freight, customs, FBA preparation. First small shipment of 1,000 units. Within 90 days, $12,000 to $15,000 in sales. Not profit yet because we were in launching phase, but now it's doing very well. The macro supports it too. After the China conflict, more than two lakh Indian sellers are exporting through Amazon. There are people who do exports and people who do marketing, but the combination of both is very hard to find. That's our edge.

🔥 ChaiNet's Hot Take: A 500-rupee bottle selling for $25 in the US. The arbitrage is real, the playbook is just hidden. Most Indian founders don't know cross-border Amazon selling is even possible.

Q: How are you using AI in your Amazon workflows?

Nirav: We use four or five tools for operational purposes. It's a human and AI combination. We use tools for data mining, PPC analysis, and proactive problem detection. We used to use AI for content but stopped because the output feels hollow. Same with graphic design tools. You can take inspiration from them but you can't just send the AI-generated image to a client. It makes our life easy for drafting, and I get cost reduction and quick delivery. But it's human and AI together, not only AI. The execution is getting faster, campaign setup went from 70 steps to 4 steps. But 90,000 plus sellers are using the AI writing tool and 90% accept the output without editing. The basic stuff, AI handles. The harder part is understanding what's happening inside the black box, like when Amazon's Cosmo algorithm reclassifies your product overnight and you drop 30 positions with no warning. No AI tool tells you what happened. That's where experience comes in.

🔥 ChaiNet's Hot Take: AI took campaign setup from 70 steps to 4. But when your ranking drops overnight because an algorithm changed its mind, no AI explains why. Experience is the last moat.

Final Thoughts: Stop Guessing, Start Reading the Data

Nirav's philosophy: "Everything I say is based on the data. There is nothing that I can say that you have to just believe."

The bottom line: Nirav's story is the kind that doesn't get told enough. No fancy degree, no VC backing, no connections. Just a delivery boy from Ahmedabad who spent nine years learning every corner of Amazon's machine and then built two companies from his home with zero loans. The first six months were brutal, no payments, a family to feed. But the constraint of having no money forced a level of hustle that bigger agencies couldn't match. Night shifts to cover US time zones, proactive communication, and pricing that gave clients no reason to say no.

The insights here are genuinely actionable. Track TCOS not just ACOS. Check keyword-level conversion rates, not blended averages. Treat your inventory spreadsheet like an SEO tool. Don't run ads on keywords you already own organically. Give away 30 units for Amazon Vine reviews before spending on ads. Fill your backend search terms. These aren't secrets, but almost nobody does them consistently.

The cross-border opportunity through Merchant Exporter is equally eye-opening. Products selling at 500 rupees domestically going for $25-35 in the US, with a clear playbook for export documentation, freight, and FBA preparation. After the China conflict, India is the fastest-growing source country for Amazon sellers. The opportunity is massive and most Indian founders don't even know it exists.

Q: How can people connect with you and learn more about Sellers Umbrella?

Nirav: You can find us at sellersumbrella.com. We recently got a brand new website. You can also connect with me on LinkedIn or Instagram. Whether it's Amazon India or selling as an Indian merchant into the US, we're happy to help. And if this episode was useful, the best thing you can do is share it with at least one founder who you think can benefit from this.

Final words: Growth, not guesswork. Three words that sound like a tagline but are actually a business philosophy. In a world where most Amazon sellers are flying blind, setting budgets on blended averages, ignoring backend search terms, and running ads on keywords they already own, the competitive advantage isn't some secret hack. It's discipline. It's checking your account daily instead of monthly. It's reading keyword-level data instead of dashboard summaries. It's treating inventory like SEO and reviews like salespeople. The playbook isn't hidden. It's just that most people would rather guess than do the work.
