Where the money goes in an app like Robinhood.

Robinhood is a trademark of its owner. Nexzem is not affiliated with Robinhood; the name only describes the type of product. Figures are 2026 estimates for building a comparable product with an experienced Indian team, converted to USD, not what any company spent.

That qualifier matters. Becoming a broker-dealer yourself means registration, capital requirements, clearing arrangements and a compliance team, which costs far more and takes far longer than the software. Most new investing apps instead partner with a broker-as-a-service provider that holds the licences, custodies the assets and executes orders, while the startup owns the product, the brand and the customer experience. With that model, the first release lands in the mid-sized band of our app cost calculator; support chat and messaging integrations in the second release move it into the large-platform band.

Investing apps are a fintech product where trust is the feature. Clear prices, honest risk warnings, fast and correct order status and a calm design matter more than animations. The figures below are estimates for a comparable product, not legal or investment advice.

Tech stack

A current stack for an app like Robinhood.

What we would reach for in 2026. Every layer has alternatives; the right pick depends on your team, budget and markets.

  • Mobile apps

    • Flutter or React Native
    • Native charts or Skia-based rendering
    • Biometric unlock

    One codebase with smooth charts and device-level security such as Face ID and fingerprint.

  • Brokerage partner

    • Broker-as-a-service APIs (for example Alpaca or DriveWealth in the US)
    • Local licensed brokers' APIs elsewhere

    The partner holds the licences, custody and execution, so you build product rather than a broker-dealer.

  • Backend

    • Kotlin, Go or Node.js (NestJS)
    • Event-driven order and account services

    Orders, fills and transfers are events from the partner; your services mirror them reliably for the app.

  • Data

    • PostgreSQL
    • Redis for quotes and sessions
    • Append-only audit log

    Account and order records need strong consistency and an audit trail that cannot be edited.

  • Market data and identity

    • Licensed real-time data feed
    • KYC and fraud vendors (for example Persona, Onfido or Sumsub)
    • Plaid or local bank-linking APIs

    Exchange data, identity checks and bank linking are specialist services best bought, not built.

  • Cloud and security

    • AWS or Google Cloud
    • KMS-managed encryption
    • WAF and SIEM
    • SOC 2-ready controls

    Partners and regulators expect documented security controls from the first release.

Cost drivers

What moves the number.

Most of the price is engineering time. These are the parts of this product that take the most of it.

  1. 01

    Licensing model

    Partnering with a licensed broker keeps the build in this range. Becoming a broker-dealer yourself adds registration, net capital, clearing and a compliance function, a multi-month process that dwarfs the software cost. Decide this first; it shapes every other decision.

  2. 02

    Market data licensing

    Real-time exchange quotes carry licensing fees and display rules, and professional and non-professional users are priced differently. Delayed data is cheaper but feels wrong in a trading app. Budget data as a running cost from day one.

  3. 03

    Order state and correctness

    An order can be pending, partially filled, filled, cancelled or rejected, and the app must show the right state instantly. Mirroring the partner's events reliably, with idempotency and reconciliation jobs, is where most engineering effort goes.

  4. 04

    Security and audit

    Strong authentication, device binding, encryption, tamper-proof audit logs and a penetration test before launch are expected by partners and app stores. Multi-factor authentication and session controls are not optional.

  5. 05

    Disclosures and communications

    Risk warnings, fee schedules, order routing information and records of customer communications are regulatory requirements in most markets. They need design and engineering, not just a legal page.

  6. 06

    Market-specific rules

    Each country brings its own regulator, account types and tax reporting. In the US, FINRA's 2026 rule change replaced the pattern day trader minimum with intraday margin requirements that brokers are phasing in through 2027, which affects how buying power is shown. Expect similar product-level changes elsewhere.

Monetisation

How products like this make money.

Decide the model before the build: it changes the payment flows, the admin panel and sometimes the app store rules you work under.

  • 1

    Subscription tier

    A monthly plan with research, higher interest on cash, larger instant deposits or lower margin rates.

  • 2

    Interest on cash and margin

    A share of interest earned on uninvested cash, and interest on margin loans, both shared with or provided by the partner.

  • 3

    Order flow and execution revenue

    Payment for order flow is permitted in some markets with disclosure and banned in others, including the UK and the EU, so check local rules before relying on it.

  • 4

    Premium products

    Options, crypto, retirement accounts or managed portfolios, each with its own fees or spreads disclosed to customers.

Deep dive

Build on a broker partner or become a broker

Broker-as-a-service providers offer APIs for account opening, KYC, funding, market data, orders and statements. You design the app, own the customer relationship and pay the partner per account or per trade. This is how most new investing apps launch, and it is the model behind the estimates on this page. In India, the equivalent is building on a SEBI-registered broker's APIs; in the UK and EU, partners authorised by the FCA or under MiFID II play the same role.

Becoming a broker-dealer gives more control over economics and features, but in the US it means SEC registration, FINRA membership, SIPC coverage, net capital and a clearing relationship. Many companies start with a partner and consider their own licence only once volume and funding justify it.

What the MVP must get right

A trading app succeeds when customers trust that what they see is true: the price, the order status, the cash available and the portfolio value. Onboarding should be quick but complete, deposits should show clearly when funds are usable, and every order should move through visible states without surprises.

Keep the first version narrow: stocks and ETFs, market and limit orders, one account type and one country. Fractional shares, recurring investments and news are natural second steps. The MVP development approach keeps compliance and engineering focused on the flows that matter most.

  • Show estimated cost and fees on the order review screen, every time.
  • Never show a filled state before the partner confirms the fill.
  • Reconcile positions and cash with the partner daily and alert on any difference.

Market data, charts and real-time updates

Quotes stream from a licensed data provider to your backend and on to the app over WebSockets. Only send updates for symbols a user is watching, and throttle them so charts stay smooth on mid-range phones. Historical prices for charts are cached and served from your own API to keep data fees under control.

Market hours, holidays, trading halts and corporate actions such as splits all affect what the app should show. Build those rules into the backend early, because getting them wrong produces alarming portfolio values and support tickets.

Regulation and security

In the US, the partner broker carries most obligations: KYC and anti-money-laundering programs, best execution, Regulation Best Interest where recommendations are made, books and records and SIPC coverage. Your app must still present disclosures correctly, avoid language that reads as personalised advice unless you are licensed to give it and keep records of customer communications. Other markets have equivalent rules under the FCA in the UK, MiFID II in the EU and SEBI in India.

Security expectations are high. Use biometric login, device binding, encryption at rest and in transit, least-privilege admin access and complete audit trails. Our cybersecurity services and security testing teams can review the design before the partner's certification. This page is general information, not legal advice.

Scaling into options, crypto and new markets

Options and margin bring approval levels, more complex order tickets, risk disclosures and real-time buying power calculations, which is why they belong in the scale tier. Crypto usually needs a separate licensed partner and its own disclosures. Each new country means a new partner, new account types and localisation.

Plan roughly 15-20% of the build cost per year for maintenance and support, plus partner fees, market data, KYC checks, messaging and cloud costs, which grow with every funded account.

Building an app like Robinhood: questions

Something else on your mind? Ask a consultant and get a reply within one business day.

How much does it cost to build an app like Robinhood?

A trading app MVP on a licensed broker's API, with KYC onboarding, bank funding, search, orders, a portfolio, alerts and a compliance console, costs roughly $40k–56k with an experienced offshore team. Adding fractional shares, recurring buys, support chat, alerts and tax documents brings the total to about $62k–96k, and options, margin, crypto and new markets take it past $120k. These are estimates for a comparable product, not what any company spent.

How long does it take to build a trading app?

Around 18–26 weeks to a first release on a partner's API, including partner certification. Growth features add 12–18 weeks. Legal and partner agreements run in parallel and can take as long as the build.

Do I need a broker-dealer licence?

Not if you partner with a licensed broker that opens accounts, holds assets and executes trades, but you still need to follow the partner's rules and local law on marketing and disclosures. Becoming a broker yourself is a much larger regulatory project. This is general information, not legal advice.

What is broker-as-a-service?

A licensed broker exposes APIs for account opening, KYC, funding, market data, trading and statements, so a startup can build its own app on top. The broker handles custody, clearing and most regulatory obligations.

How much does real-time market data cost?

It depends on the exchanges, the provider, the number of users and whether they are classed as professional. Real-time data is a recurring cost that grows with users, so get quotes early and design caching around it.

Can I offer crypto in the same app?

Yes, through a separately licensed crypto partner with its own disclosures and, in many markets, its own registration requirements. See our Coinbase cost guide for what a crypto product involves.

What happened to the pattern day trader rule?

In 2026 the SEC approved FINRA changes that replace the pattern day trader designation and its $25,000 minimum with an intraday margin framework, which brokers are phasing in through 2027. If you build on a partner, ask how and when their accounts move to the new rules.

Which security measures does a trading app need?

Multi-factor or biometric login, device binding, encryption, secure session handling, audit logs, rate limiting and a penetration test before launch. Partners usually require evidence of these controls before go-live, and many ask for a SOC 2 report as you grow.

Can I build an investing app for India or the UK?

Yes. In India you would build on a SEBI-registered broker's APIs; in the UK on an FCA-authorised partner, possibly with ISA support. The app architecture is the same; partners, account types and disclosures change.

Is Nexzem affiliated with Robinhood?

No. Robinhood is a trademark of its owner, and we use the name only to describe a type of product. The figures are estimates for building a comparable investing app, not what any company spent.
