MM Ep-104 – Platform Business as the Driver of Growth for Financial Services!

Hi ,

If you look at the most flourishing businesses in the last 8 to 10 years, there’s a pattern that’s hard to ignore.

Amazon. Uber. Facebook. Google.

They are all platform companies.

Yes, individual companies are growing. But if you go deeper — really look at who is driving outsized growth — it’s the platform businesses that are dominating.

And here’s what’s interesting for us as architects: Financial services, one of the largest industries in the world, has been built on a product-centric model for decades. You build a product. You sell a product. You grow by adding more products.

That model is hitting a ceiling.

The next phase of growth in financial services won’t come from building better products. It will come from building better platforms.

And that shift — from product-centric to platform-centric — is fundamentally an architecture problem.

The fundamental shift: From owning everything to orchestrating ecosystems

The traditional financial services model is built on ownership — your products, your channels, your systems, your workforce, your customers.

That model has worked for decades, and it still works. But its growth is limited to organic customer acquisition — one customer at a time, through your own channels, within your own boundaries.

To grow at a rate faster than organic acquisition, financial services has to move to a platform-centric model — one where you’re using others’ channels, leveraging other companies’ services, and orchestrating applications across multiple enterprises.

And here’s what makes this shift even more powerful now: platforms are the hotbed for AI and agentic interventions. Intelligent, meaningful AI orchestration that crosses enterprise boundaries — not just working with your own data, but with acquired and partner data.

• Own channels and own customers TO Partner channels and ecosystem participants
• Proprietary data and closed systems TO Shared data and cross-enterprise orchestration
• Organic growth through product sales TO Exponential growth through platform economics

The value proposition of a platform model is significantly bigger than what any product-centric business can unlock — in volume, in reach, and in the intelligence it can generate.

The question is: what does this re-architecture actually look like in practice?

What this means: Three architectural shifts reshaping financial services

Shift 1: Closed systems TO API-first ecosystem integration

If you’re aware of open banking, you know the potential it has to unlock new business opportunities. Just imagine — if every business process of a bank is exposed as an open API, on authorization, they can be invoked. You can onboard customers. You can service customers. You can sell to customers. You can even find out the credit rating of customers. And these customers may or may not be your own. They might have been sold your product, completely white-labelled under somebody else’s umbrella. Or maybe your product is sold in your name, but the servicing and other aspects of the customer lifecycle are handled by a partner.

This is only possible if you think about the business as modular, service-oriented, composable architecture — and expose them as APIs. That’s API-first thinking. And that’s fundamentally different from the earlier closed systems.

Shift 2: Product P&L TO Platform economics

And that’s where platform economics actually spreads much wider than what product P&L used to be. Now your value proposition is not just your own products — it’s partner products, third-party products, all coming together to create a significantly bigger value proposition. In fact, yesterday’s non-customers can become your customers.

Shift 3: Proprietary channels TO Embedded finance

In the process, you embed your products and services into customer journeys that you are not even aware of — but you are aware of the fact that they are being embedded as seamlessly as possible, by either your partner or by you, in the process of ecosystem participation.

Where it comes together: Platform thinking in the customer’s journey

And if you think this is something new for financial services — it’s not.

There have been two major tipping points in the industry that showed us exactly where things were headed.

PayPal — in the early 2000s, PayPal embedded payments into the e-commerce journey. You were buying something on eBay, and PayPal was right there.

No separate banking process. No friction. Financial services embedded into the customer’s journey. That was the first signal.

Stripe — took it further. Stripe made financial services programmable. API-first. Developer-first.

Any company could now embed payments, lending, even banking into their product. Stripe didn’t just participate in the platform economy — it became the infrastructure for it.

These two tipping points proved that platform business models fundamentally change financial services. From banking as a service to embedded finance — a customer searching for a house finds a home loan right there.

A customer exploring an educational program discovers the best loan without leaving that journey.

A customer buying a car gets motor insurance at the point of decision.

The customer is already in a journey, and your products are embedded into it. That’s platform thinking at its best.

In Conclusion

So to bring it all together:

The traditional model — our products, our channels, our customers — is hitting a growth ceiling. The shift to platform-centric business means composable, API-first architecture that orchestrates across ecosystems.

It means platform economics that are wider than product P&L.

It means embedding your services into customer journeys you don’t own. And it means AI and agentic interventions that create value across enterprise boundaries.

The architecture for this is not tomorrow’s problem.

It’s one of today.

That’s all for this week. Hope, it was useful.

Till next episode.
