How to Start a Fintech Company

Start with the financial activity, not the app

A fintech company uses technology to deliver or support financial services. That can mean selling accounting software, operating a payment service, arranging loans or issuing electronic money. These businesses have very different capital, compliance and operational requirements.

The first question is therefore not which technology to build. It is: what will the company do with customers’ money, data and financial decisions?

This guide provides a planning framework, not individual legal or financial advice. Licensing boundaries depend on the exact service, customer location and contractual arrangements. Confirm them with qualified advisers and the relevant regulator before accepting customers or funds.

1. Define a narrow problem and a workable business model

Choose an identifiable customer group and a specific problem. “Better banking” is too broad. Helping small exporters reconcile incoming payments is a clearer starting point.

Interview potential customers about their existing processes, costs, failure points and willingness to switch. Test demand with prototypes that do not move real money or imply that an unlicensed service is available.

Document:

• Customer: consumers, businesses or regulated institutions.
• Service: the precise task being performed.
• Revenue: subscriptions, transaction fees, commissions, interest or another source.
• Costs: processing, partners, fraud, compliance, support and infrastructure.
• Distribution: how customers will discover and adopt the product.

Calculate contribution margin after direct operating costs. A payment fee is not pure revenue: processing charges, fraud losses, chargebacks and support can consume it. Lending models must also account for funding costs, defaults and collections.

2. Draw the money, data and responsibility flows

Create a diagram showing every party involved in a transaction. Include the customer, your company, banks, processors, identity providers and recipients.

For each step, record who:

• Receives, holds or controls funds.
• Executes or initiates a payment.
• Maintains the legally relevant customer balance.
• Makes credit or investment decisions.
• Collects personal information and determines its use.
• Handles complaints, refunds and losses.

For example, a business expense app might simply display information from a licensed provider. Alternatively, it might contract with customers to provide payment accounts and instruct transfers. Similar screens can conceal very different legal responsibilities.

Distinguish customer funds, company operating cash and regulatory capital. They serve different purposes. Customer balances must not become an informal source of funding for payroll or growth.

3. Identify the regulatory perimeter

A fintech label does not create a licence category. Regulators generally assess the underlying activity.

Common triggers include deposit-taking, payment execution, e-money issuance, lending, credit broking, investment services and certain cryptoasset activities. Account-information services can also require regulatory status even when the provider never holds funds.

European Union

PSD2 provides a framework for payment services, while EMD2 addresses electronic money. Banks operate under separate banking legislation. MiCA establishes requirements for covered cryptoassets and related services; it does not replace every other financial-services rule.

Authorisation normally involves the competent authority in a home Member State. Some permissions can support cross-border activity through passporting procedures, but this is not universal. Lending and consumer-protection requirements can also involve national law.

Check the applicable legislation and supervisory guidance, including any amendments or transition arrangements, rather than assuming that an older framework remains unchanged.

United Kingdom

The Financial Conduct Authority oversees payment and e-money firms under the relevant UK regimes, with different authorisation or registration routes where applicable. It also regulates many credit, investment and other financial activities.

Establishing a bank involves the Prudential Regulation Authority and the FCA. UK permissions do not automatically provide access to EU markets.

A payment or e-money balance is not automatically a bank deposit protected by the Financial Services Compensation Scheme. Disclosures must accurately explain the applicable protection.

United States

The US combines federal and state requirements. A money-services business may need federal registration with FinCEN and state money-transmitter licences, depending on its activities and available exemptions. FinCEN registration is not a substitute for state licensing.

Lending, securities and banking introduce additional authorities and rules. A sponsor-bank relationship does not remove every obligation from the fintech.

Deposit insurance applies to qualifying deposits at insured banks, subject to legal requirements. A non-bank fintech should not suggest that its entire business or every customer balance is federally insured.

Switzerland

FINMA supervises several relevant licence categories. Depending on the model, a business may require banking, FinTech or securities-related permissions, alongside anti-money-laundering obligations.

The Swiss FinTech licence permits limited acceptance of public deposits under specific conditions; it is not a full banking licence. Restrictions include how accepted funds may be used and whether interest may be paid. Check FINMA’s eligibility criteria and depositor-protection disclosures.

United Arab Emirates

First distinguish the UAE’s federal framework from the separate financial regulatory systems in the Dubai International Financial Centre and Abu Dhabi Global Market.

The Central Bank of the UAE regulates relevant banking, payment and stored-value activities within its remit. The DIFC’s DFSA and ADGM’s FSRA have their own frameworks. Virtual-asset regulation can involve additional authorities depending on location and activity.

A commercial incorporation licence or free-zone registration is not, by itself, permission to provide regulated financial services.

Singapore

The Monetary Authority of Singapore administers the Payment Services Act and other financial-services frameworks. Payment permissions depend on the services performed and the applicable licence category, thresholds and exemptions.

Banking, lending, investments and digital-token activities require separate perimeter analysis where relevant. A payment licence is not blanket permission to offer every financial product.

4. Choose your operating model

Obtain your own permissions

Direct authorisation can provide greater control over product design, customer relationships and operations. It also brings capital, governance, reporting and supervisory responsibilities.

Applications typically require credible management, financial forecasts, ownership information, policies and evidence that the business can operate safely. Permission must cover the actual service, not merely a nearby activity.

Operate through a licensed partner

A bank or licensed payment institution may provide regulated infrastructure while your business supplies distribution, software or customer operations.

Define who contracts with customers, holds funds, performs checks and resolves complaints. Depending on the jurisdiction and role, your company may still need registration, authorisation or formal appointment as an agent.

Assess the partner’s termination rights, pricing changes, service interruptions and migration support. A contract is not a substitute for understanding the legal structure.

Sell software without providing the financial service

A business-to-business software model may sit outside financial licensing where it does not perform regulated activities. It can still face privacy, cybersecurity, outsourcing and contractual requirements.

A regulatory sandbox may support supervised testing, but entry does not generally amount to unrestricted market authorisation.

5. Establish the company, governance and funding

Choose an incorporation location based on customers, management presence, regulatory access and operational substance—not only tax or filing costs.

Agree founder ownership, decision rights, intellectual-property assignments and departure arrangements. Recruit people who understand both the product and its financial risks.

Your funding plan should distinguish:

• Operating runway: salaries, suppliers, legal work and customer acquisition.
• Regulatory capital: resources required to obtain and maintain permissions.
• Liquidity: cash needed to meet obligations when due.
• Contingency resources: funding for incidents, delays and an orderly wind-down.

Do not assume authorisation will arrive on a fixed date. Budget for application questions, partner due diligence and slower-than-expected customer onboarding. Required capital is not simply a launch expense that can subsequently be spent without restriction.

6. Build compliance into the customer journey

Convert legal obligations into operating procedures and system controls.

Where applicable, customer due diligence includes identity checks, beneficial-ownership verification and risk assessment. Ongoing monitoring should detect suspicious behaviour, with escalation and reporting procedures appropriate to local law.

Sanctions screening, fraud controls and anti-money-laundering monitoring are related but distinct. A transaction may be fraudulent without being money laundering, or prohibited even when the customer’s identity is genuine.

Also address:

• Clear pricing and product disclosures.
• Complaints, errors and dispute resolution.
• Privacy, data retention and cross-border transfers.
• Fair treatment, accessibility and vulnerable customers.
• Creditworthiness or suitability assessments where required.

Automated tools need accountable owners and review processes. Outsourcing identity verification does not automatically transfer responsibility for its adequacy.

7. Engineer reliable financial operations

Build a ledger and reconciliation process

If the product maintains financial balances, use an auditable ledger with controlled entries. Design for failed payments, duplicates, reversals, fees and delayed settlement—not just successful transactions.

Reconcile internal records against banks and processors. A difference between the app’s displayed balance and external records must trigger investigation, not an undocumented manual adjustment.

Where safeguarding applies, implement the required segregation or other permitted protection arrangements. Safeguarding and deposit insurance are different mechanisms; neither should be described as an unconditional guarantee of immediate repayment.

Protect systems and manage suppliers

Apply least-privilege access, strong authentication, encryption, secure development and independent testing. Establish incident response, backups and recovery procedures, then test them.

Assess critical suppliers for security, concentration risk, subcontracting and exit arrangements. In the EU, DORA creates operational-resilience obligations for in-scope financial entities. Other jurisdictions impose their own technology-risk and outsourcing requirements.

The practical question is simple: if a critical supplier fails, can you identify customer balances, communicate clearly and restore essential services?

8. Launch in stages and plan for failure

Launch only when permissions, partner approvals, controls and customer documentation are in place. Start with a limited product and manageable customer cohort, using transaction limits where appropriate.

Monitor payment failures, reconciliation breaks, fraud losses, complaints, support demand and onboarding exceptions. These indicators reveal whether growth is creating risks that headline revenue conceals.

Maintain a wind-down plan covering customer communication, return or transfer of funds, records, contractual exits and regulatory notifications. Review it as the business changes.

Before expanding into another jurisdiction or adding lending, investments or cryptoassets, repeat the perimeter analysis. The most durable fintech businesses treat regulation, financial operations and technology as one operating system—not separate projects completed just before launch.
