A funded founder without engineers can rent a white-label terminal, license a platform or have one built. This guide compares what the company keeps on each route, how each bill grows and when to switch.

With funding and no engineers, you can rent a white-label terminal, license a trading platform and run an installation of your own, or have an engineering firm build a terminal your company can own. For the first two you talk to platform vendors. For the third you talk to engineering firms, and each one should be able to show a trading system it built that clients use today. At launch, renting asks the least of you, because the vendor runs everything. Building starts to pay off when the rent at the number of client accounts you expect in two years passes the cost of owning. It also pays off when clients would choose you for a screen no vendor offers.

The short answer: decide by what the company must own and by the number of live client accounts you expect in month 24. Rent or license while the vendor's terminal does what your clients need and its fees at that number stay below the cost of owning. On any route, register the domain and the app store developer account to your company, and have the vendor contract give you the right to export client accounts and trade history.

What is the difference between renting, licensing and building a terminal?

Vendors use these names loosely. Sort each offer by its terms: who runs the servers, who holds the client database and how the fee grows.

  • Renting a white-label terminal. The vendor runs one platform for many companies and puts your brand on your copy. It keeps the code, the servers and the client database. You pay monthly, often by the number of client accounts, in tiers or plan limits
  • Licensing the platform. You pay for an installation of your own. Depending on the vendor, it runs on your servers or on servers the vendor provides. It can give you the full client database and your own choice of brokers and data vendors. The code stays the vendor's
  • Building your own. An engineering firm builds a terminal to your specification. The code becomes your company's if the contract transfers it, and your company pays to run and change it

Match-Trader, for example, sells its platform both ways. Its page, read on 14 October 2026, describes a white label package and a server licence. The server licence gives the broker “access to the full database” and lets it connect its own liquidity and market data providers.

Some costs belong in the budget whichever route you choose: access to markets through brokers or exchanges, and licences for the exchange prices you show. The article on what a multi-asset terminal needs explains them. Some vendors include part of them in their price, so ask each one which.

When does renting start to cost more than owning?

Each bill grows in its own way. Rent and licence fees can rise with the number of client accounts, often in tiers. A terminal of your own takes a large part of the money before the first client logs in. After launch it costs money to host, monitor and change, and that cost follows the work you ask for more than the number of accounts.

Vendor terms also differ more than the names suggest. Some vendors ask for a setup fee and a minimum term. Leverate's page for its Sirix white-label platform, read on 14 October 2026, states “No Set-up fee or Commitment period” and 30 days' notice for termination. Get both answers in writing from every vendor.

To find the month when owning becomes cheaper, write down the number of live client accounts you expect at month 6, month 12 and month 24. Ask each vendor to price those three points in writing, with every charge per account or per amount traded. Ask each engineering firm to price the first version plus running and changing it up to month 24. Then add up each route's monthly costs to month 24. This article uses two years; if your funding plan covers a longer period, extend the sum.

If renting has the smallest cost up front in your quotes, it stays the cheapest route until its running total passes the cost of owning. That month may or may not come within two years. Add the cost of leaving to the rented and licensed routes as well. It covers moving client accounts and history to another terminal, repeating any broker or exchange tests the new software must pass, and paying for both systems while they overlap.

What does the company lose when a vendor contract ends?

On a rented terminal, the vendor owns the software and runs the servers and the database where your clients' accounts and trades are kept. Your company keeps what the contract lets it export, such as client records and trade history in the format the contract names. The contract also sets how long the vendor must keep the terminal running after notice. A licensed installation can leave more with you if the licence gives you the full database. On both routes the code stays with the vendor.

The domain and the mobile apps can be yours on every route, as long as they are registered to your company and not to the vendor. Apple's App Store Review Guidelines, last updated on 8 June 2026, reject apps created from a “commercialized template” unless they are “submitted directly by the provider of the app’s content”. They tell template services not to submit apps on behalf of their clients. They also let a template provider publish one app that holds all its clients in a “picker” model, and then the app in the store belongs to the vendor.

For an app under your own brand, expect it to go out from the app store developer account of the company that provides the trading service. The guidelines say apps used for financial trading “should be submitted by the financial institution performing such services”. That is your company if it holds the licence. Ask a lawyer how the rule on trading apps applies to you before you plan an App Store launch.

If your company signs the broker and exchange agreements, they stay when the vendor goes. If the vendor provides access to markets through its own agreements, that access ends with the vendor contract. Your clients then cannot trade there until you sign new agreements and, where a broker or exchange tests new software before letting it trade, pass those tests.

On the build route, the code is yours only if the contract transfers the rights to your company. The article on code rights explains what that clause has to say.

What does a regulator expect when the terminal is rented or licensed?

Renting or licensing the terminal does not move a regulated firm's duties to the vendor.

In the United States, FINRA's Regulatory Notice 21-29 of 13 August 2021 quotes an earlier notice, 05-48. Outsourcing an activity or function to a vendor “does not relieve members of their ultimate responsibility for compliance” with the securities laws and FINRA rules that apply to it. If your firm is a FINRA member, a rented terminal that goes down or mishandles an order is still your firm's compliance problem, not only the vendor's.

In the European Union, the Digital Operational Resilience Act (DORA) covers investment firms, trading venues, crypto-asset service providers and other financial entities. Its Article 28 says they “shall, at all times, remain fully responsible” for their obligations when they use outside technology services. It also requires an exit strategy for services that support critical or important functions, which DORA defines as functions whose disruption would seriously harm the firm's business or its compliance. Whether your terminal counts as one is a question for your compliance adviser. The article on founders without a CTO lists other contract terms DORA requires.

What should the vendor contract say so we can leave later?

If you rent or license now and may build later, ask for these terms in the first contract.

  • Export of all client accounts, orders and trade history at any time, in a documented format, without an extra fee
  • A notice period, plus a transition period during which the vendor keeps the terminal running while you move. DORA's Article 30 asks EU financial firms for such a transition period in contracts for services that support critical or important functions
  • A limit on price increases at renewal
  • Written permission to connect a screen of your own to the vendor's system through its API, the interface it offers to other software. That opens a middle route, in which you later build only the screen and keep renting the rest

When should we stop renting and build?

Check the signs against your plan every quarter. A rented or licensed terminal stops fitting when its monthly bill at your current number of accounts is higher than owning would cost. Other signs are a workflow clients keep asking for that the vendor will not build, a broker or exchange it does not connect to, and competitors running the same terminal under their own brands.

Building has its own risks. The money can run out before the first version reaches clients, and the builders can leave without a handover. Paying in milestones and keeping the code in your company's accounts from the start reduce both, and the article on founders without a CTO shows how to set that up.

Does amBrain build trading terminals?

On the build route, amBrain is one of the engineering firms you can ask. It has been building software since 2019. Its website lists “Trading terminal development, order management systems, and FIX protocol exchange integration.” among its services, and amBrain builds algorithmic trading infrastructure: order execution, market data and pre-trade risk controls.

It works in three formats: full delivery, a dedicated team, or engineers embedded in your team. Its line on ownership is “The client keeps full ownership of the product and the code, except our reusable components.” Ask which components those are, by name, before you sign.

Nothing in this article describes an amBrain project, and it gives no amBrain prices or timelines.
