Mentor

On 4th July 2005 at 5:52 UTC, my life changed

This day taught me how a 15-year-old child sitting in a small town of Ahmedabad, India, through a connection and by taking an initiative can be part of something bigger, that takes one out of the world. 

NASA launched its bold mission to impact the comet and few people from earth got a chance to be part of that mission and I was one of them. The Deep Impact spacecraft travelled 429 million km (267 million mi) in 174 days to reach comet Tempel 1 at a cruising speed of 28.6 km/s (103,000 km/h; 64,000 mph).

This incident changed my perspective on how small things can lead to a big impact you can never think of.

In the following years, I excelled at education, worked with cross-functional teams from product, technology, operations, marketing,  sales, customer success to drive and to lead companies on collaborative, strategic initiatives leading to an impact of 300M$+

Over the last decade, I have worked with early stage startups, SMBs, Enterprises and Government Institutions and worked on cross-functional projects to deliver impact.

Now, I work with SaaS companies to increase their onboarding & retention through product growth and  generating a product strategy that makes the user comes back and get their job done by taking a unique collaborative cross-functional inter-department approach with sales, marketing, product and tech teams.

“Chatbots for ecommerce don't work.”
There I said it…

Since 2023, we have been paid tens of thousands of dollars to build exactly those. 

We’ve built, launched, and analyzed dozens of ecommerce chatbots for small DTC brands, retail giants, and marketplaces. 

After reading through thousands of real customer conversations, one brutal truth keeps surfacing, now in almost-2026.

But before you cancel your chatbot project, let me add the nuance: they can work—but almost never in the way we originally imagined.

The flawed assumption we all made

Back in 2024/25. We thought users would land on a merchant's site and ask the AI, "What's the best running shoe for me?" or "Help me find a gift under $50." 

We assumed they'd treat it like an unbiased shopping assistant.

Here's why that falls apart:
Trust is dead on arrival. Users aren't naive. 

They know a brand's chatbot will only recommend that brand's products. The "unbiased advisor" pitch was never believable.

Quality control is a nightmare. Even if you wanted unbiased advice, how do you verify the bot's answers?

One hallucination about material safety or sizing, and you're facing a PR disaster.

The mobile experience is terrible. 70% of traffic is mobile. 

Nobody wants to type full sentences into a tiny corner widget on their phone. It's clunky, slow, and frustrating.

ChatGPT already won. 
Why would I use your chatbot when I already have the ChatGPT app? 

It knows my style, my budget, my quirks—I talk to it for hours. Your bot doesn't know me and never will.

So where do chatbots actually work?

Here's the pivot: Discovery within a brand.

When a customer is already on your site—because they love your aesthetic or trust your quality—they don't need selling. They need navigating.

Example: "Build me a complete work-from-home outfit using only your new collection." Or, "Show me everything in muted olive green."

This is where conversational AI shines. Not as a shopping advisor, but as a personal catalog curator.

The implementation fix nobody's talking about - 
Stop putting chatbots in the bottom-right corner.

That's not where discovery happens. Discovery happens in the search bar.

We're working on a POC that moves the conversation into search. 

Users type naturally, the AI responds with products inline, and it feels like upgrading search—not adding another layer.

The lesson? Don't fight ChatGPT. Don't try to replicate it. Instead, make your own discovery experience better.

Bottom line: The future isn't a chatbot that talks. It's a search bar that listens.

Agree? Disagree? Have you seen chatbots work differently? Let me know in the comments.

We predicted this. "Shopping Research" in ChatGPT just launched —an deep research experience that asks clarifying questions, scours the web, and delivers personalized buyer guides in minutes.

We mapped this exact trajectory months ago.

Our white paper predicted how foundation model companies would evolve from assistants to autonomous shopping agents, and why this signals the end of the SaaS dashboard as we know it.

In 24 months, your most engaged customers will be the ones who never log in at all.

The three-layer architecture we outlined—Agent-to-Site → Agent-to-Agent → Broker-Agent-to-Site—is unfolding in real-time. 

OpenAI just made Layer One consumer-facing.

Layer Two (Merchant APIs) and Layer Three (Broker Agents) are next.

For retail & e-commerce SaaS platforms, this isn't a feature update. It's an existential pivot:

• GEO (Generative Engine Optimization) becomes table stakes
• GXO (Generative Experience Optimization) decides who wins the transaction
• Your moat isn't UI/UX anymore—it's how easily AI agents can negotiate with your backend

We've spent 5 years building agent-ready architectures for 40+ platforms. The 2-year window we predicted is now a 2-year deadline.

Is your platform is architected to survive this & the dozen other upcoming launches shaping how we shop?

Like + comment anything on this post and I'll DM you our full strategic briefing. Drop me a DM if you want to discuss what this means for your roadmap.

You're running an e-commerce brand with 1,000+ SKUs.

Every time you launch a new product, someone has to manually figure out what bundles well with it.

Your merchandising team is buried in spreadsheets. Your agency doesn't have direct access to product data. 

And the marketing team is waiting on three approvals just to update a "Frequently Bought Together" section. Sound familiar?

The problem with manual bundling at scale:
→ Hundreds of possible combinations per product 
→ Multiple teams, zero coordination 
→ Legacy systems that don't talk to each other 
→ Incomplete product data everywhere

We built a dynamic bundling system that sits on top of your existing setup. No massive overhaul needed.

When someone views a coffee maker, the system thinks: "They're trying to make coffee. What else do they need?" 

Then it suggests coffee beans, filters, grinder. Contextual, not random.

Someone buying gym shoes and a fitness tracker? Gets tagged as fitness enthusiast. 

Now protein bars and organic foods show up in their bundles.

The system runs in the background. Adapts to inventory changes, seasonal shifts, new SKUs. 

Your team focuses on growing the business instead of managing bundle spreadsheets.

We've deployed this for mid-market e-commerce brands dealing with exactly this operational nightmare.

If you're juggling thousands of SKUs and bundling feels impossible to scale, let's talk.

"If ChatGPT can answer product questions better than your site can, why would anyone visit your site first?"

ChatGPT Shopping dropped last week. (Something we predicted, 1st white paper)

Now, we are writing our 2nd predictions essay, "The Aftermath" - where the industry goes next and the ripple effects on marketplaces, brands, and the SaaS companies that serve them.

Fellow men & women leaders in retail & ecom.  Have you considered the 

-  EFFECT of the impending shopping assistants roll-out?

- IMPLICATION of chatgpt ads for your business?

- CUSTOMER STRATEGY for what will be the most demanding, inquisitive buyers of the melliania -  customers who now expect instant, perfect answers just like they get from their "AI".

Drop me a message, comment, start a conversation what do you think, where is the space going? First impressions?

"Where do you see this space going in the next 12 months?"

I will be picking the best insights to feature in the final essay.

it has burnt a hole in my retinas yes.
