6 Fintech Business Ideas in India: Real Licenses and Costs

Most people who want to start a fintech company in India assume they need a banking license. They don't, and that's exactly why the cheapest, least regulated fintech business model, building the API infrastructure other fintechs run on, is also one of the most crowded. Setu got acquired by Pine Labs in 2022 building that same infrastructure layer. Zeta raised a $250 million round from SoftBank at a $1.45 billion valuation doing a version of the same thing. Six real fintech business models exist in India today, and each one answers to a different regulator, a different net worth floor, and a completely different runway to revenue.

API Infrastructure: The No-License Option Everyone Already Knows About

This is the business model with the lowest regulatory floor because you never touch customer money directly. You build the KYC, payments, or data-access APIs, and the fintechs and banks that plug into you hold the actual licenses. Setu built this and was acquired by Pine Labs in 2022. Decentro, founded in Gurugram in 2020, does the same for KYC onboarding, escrow, and payouts. Zeta went further, working directly with banks on core infrastructure, and raised $250 million from SoftBank at a $1.45 billion valuation doing it.

Verdict: the easiest fintech business to start on paper, and the hardest to win, because you're not filling a gap, you're competing with companies already valued in the billions for the same bank and fintech clients.

Payment Aggregator: The ₹25 Crore Club

If your business collects and settles merchant payments, RBI classifies you as a Payment Aggregator, and the entry ticket is steep: a net worth of ₹15 to 25 crore. This is not a bootstrapped weekend business. Razorpay is the model everyone points to, reporting roughly ₹33 crore in net profit alongside three-year revenue growth of more than 44% annually, and it took years of venture funding to clear the net worth bar before it ever collected a rupee legally.

Verdict: only pursue this with real funding already committed. Nobody bootstraps their way to ₹15 crore in net worth before writing a line of production code.

PPI and NBFC: The ₹5 Crore and ₹2 Crore Doors

Two lower-but-still-serious tiers sit below Payment Aggregator status. Issuing a digital wallet or prepaid card falls under PPI norms, needing ₹5 crore in net worth. Underwriting loans or carrying credit risk needs an NBFC registration, at a comparatively lower ₹2 crore.

The NBFC lending route has shifted shape recently. Consumer BNPL is shrinking under tighter RBI rules, so most new lending fintechs are moving into B2B credit instead: invoice financing, inventory financing, and embedded credit lines sold through other companies' checkout flows rather than direct-to-consumer apps.

Verdict: the PPI door is mostly closed in practice, since Paytm and PhonePe already own wallet mindshare at national scale. The NBFC door is genuinely open if you aim at B2B credit, not consumer BNPL.

Account Aggregator: The Quiet ₹2 Crore Niche

This is the least talked-about fintech license in India, and arguably the most interesting one for a smaller team. An NBFC-AA moves financial data, not money, acting as a consent-based bridge between institutions that hold your financial records and the apps that want to use them. PB Fintech secured its own NBFC-AA approval the same way any new entrant must: an in-principle RBI approval, then 12 months to raise ₹2 crore in net owned funds before operating commercially, integrating through Sahamati's coordination layer and ReBIT's API specifications.

Verdict: the most underrated option on this list. Lower capital than a Payment Aggregator, a genuinely newer category with fewer entrenched players, and it sidesteps the credit-risk headaches that come with NBFC lending entirely.

Neobanks: A Warning, Not an Idea

A neobank doesn't need its own banking license, it partners with an existing licensed bank and builds the customer-facing app on top. That low barrier is why the category is now crowded with businesses that don't work. More than 76% of neobanks remain unprofitable in 2026, largely because the unit economics never matched the model: high customer acquisition cost, thin fee income, and a partner bank that can walk away from the arrangement whenever it wants.

I'd steer almost anyone away from a pure neobank play in 2026.

The category isn't broken because the idea is bad. It's broken because too many teams built the app first and the revenue model second.

Verdict: skip it, unless you already have a specific underserved customer segment and a genuine cost advantage a partner bank can't undercut.

Where the Real Opportunity Actually Sits

Of the six, I'd rank Account Aggregator and B2B embedded credit as the two genuinely under-exploited options right now, both need real capital and real compliance discipline, but neither is fighting a company already worth a billion dollars for the same customer. API infrastructure and neobanking are the two traps: cheap to start, brutally expensive to win.

FAQ

Do you need an RBI license to start a fintech company in India?

Only if you touch customer money or credit directly. Payment Aggregators need RBI approval and ₹15-25 crore net worth, PPI issuers need ₹5 crore, and NBFC lenders need ₹2 crore. API infrastructure providers that don't hold funds or extend credit don't need a direct RBI license at all.

What is an Account Aggregator business in India?

An Account Aggregator (NBFC-AA) is an RBI-licensed entity that moves financial data, not money, acting as a consent-based bridge between institutions holding financial records and apps that want to use that data. It needs ₹2 crore in net owned funds within 12 months of in-principle RBI approval.

Are neobanks a good fintech business idea in 2026?

Generally no. More than 76% of neobanks are unprofitable as of 2026, largely due to high customer acquisition costs and thin fee income relative to their partner-bank dependency.
