Every trading software vendor promises low latency, bank-grade security, and a slick UI. That's easy to write on a service page. It's harder to prove.
So this article skips the promises and looks at real projects. We picked five companies that build trading platforms and read through their published case studies. Here's what we checked for:
-
Trading or capital markets work in the published portfolio
-
At least one detailed case with a named client or a clearly described product
-
Clear info on what the team actually built, not just "we helped"
-
Some kind of outcome, like users, throughput, speed, or cost
This isn't a ranking. The projects are very different: a white-label CFD platform, an OTC platform builder, a crypto and fiat liquidity engine, a digital bank's multi-exchange trading platform, and an internal investing and trading desk tool. And that's the point. The right partner depends on what kind of trading product you're building.
Comparison of the Best Custom Trading Platform Development Companies
The top software development companies specializing in custom trading platform development include Devexperts, IT Craft, DashDevs, Intellias, and CHI Software. Here is a comparison of them:
Devexperts
Devexperts was founded in 2002 and builds software for banks, brokerages, exchanges, and wealth managers. It has more than 800 employees across 10 offices. Most of its client work starts from its own DXtrade platform, then gets customized and white-labeled for each broker.
Strengths: deep capital markets focus, a ready multi-asset trading platform to build on, flexible risk management tools.
Case: Deriv X for Deriv. Deriv is a Malta-based online broker founded in 1999, with offices in 13 countries. It wanted to attract younger traders who expect a modern interface, and its existing system was very complex. The platform also had to handle heavy load and support Deriv's own synthetic indices.
Devexperts delivered a turnkey desktop and mobile solution built on DXtrade and white-labeled as Deriv X. Traders get a performance dashboard, a trading journal, linked widgets, custom layouts and watchlists, and pop-outs for multi-screen setups. Brokers can set risk rules by user group, instrument, and account in any combination. The platform covers CFDs on forex, commodities, and crypto, plus synthetic indices that trade 24/7.
It launched in October 2022. In less than a year, Deriv's user numbers went up by more than 50%, and the platform handled the growth without trouble. Keep in mind this is a white-label build on an existing product, not a platform written from scratch. That's faster, but you're tied to the vendor's core.
IT Craft
IT Craft has been building custom software since 2001 and has a team of 330+ specialists. On the trading side, the company reports 20+ years in trading platform development, 50+ delivered FinTech and capital markets projects, and 95% client retention on long-term trading solutions. It works with hedge funds, brokerages, exchanges, futures commission merchants, and fintechs, and its trading work covers OTC solutions, stock, futures and obligations platforms, precious metals trading, crypto trading software, and automated trading tools.
IT Craft’s strengths: Fintech web platform development using the .NET framework, OTC and white-label trading platforms, real-time trading operations, configurable multi-product trading, secure user management, scalable cloud infrastructure on AWS, MVP development with a small team that scales later, fast release cycles driven by user feedback, and full handover with documentation and IP protection.
Case: Predira, a white-label OTC trading platform builder. One of the cases in IT Craft's portfolio is Predira. IT Craft developed a web-based platform builder for interdealer brokers who lack OTC solutions in their niche, which lets businesses launch their own branded OTC trading platforms in minutes and configure trading products, logos, and terms of service, so they can automate and replicate negotiation processes instead of handling them by hand. The result is real-time, high-performance trading and lower operating costs through faster negotiations and more transparency, though the case doesn't publish exact numbers.
Here's what made this project tricky. Predira wanted to move fast, so IT Craft reused what it had learned building Limpid Markets, an earlier OTC trading solution. The client also wanted to start with a small team and grow only when users showed interest, which meant careful estimates and tight scope from day one. The team had to pick up a new, complex stack quickly: TypeScript, React, and Redux on the front end, a GraphQL back end, and AWS with Cognito for authentication and DynamoDB for storage. Updates went out often, so user feedback could shape the product early.
DashDevs
DashDevs was founded in 2011 and works only in fintech. It reports 15+ years in regulated finance and 100+ launched fintech products. It also builds Fintech Core, its own modular platform with ready ledgers, wallets, KYC, and payments that it uses as a base for client projects.
DashDevs’s strengths: regulated fintech and compliance experience, high-load trading and liquidity infrastructure, a reusable fintech core that shortens launch time.
Case: digital assets trading platform for an APAC fintech. The client is a licensed fintech in the Asia-Pacific region, not named in the case. Its fiat and crypto liquidity sat in separate systems, it expected peaks of 30,000 transactions per second, and it had to meet EMI and VASP licensing rules, including KYC, KYB, KYT, and the Travel Rule.
A 12-person team built the platform in 6 months on top of Fintech Core. It includes a matching engine with market, limit, and stop-loss orders, multi-currency bank accounts, crypto wallets, fiat on and off ramps, and APIs for market makers and partners. Keys are managed in-house, and hot and cold wallets rebalance on their own. There's also a back-office "command center" for users, limits, and liquidity.
The published results: 30,000+ transactions per second, matching latency under 40 ms, a 95:5 liquidity ratio kept up by automated rebalancing, and 20+ supported crypto assets.
Intellias
Intellias was founded in 2002 and has 3,000+ experts. Financial services is one of its main industries, and it works on trading systems, market data platforms, and banking apps.
Intellias’s strengths: banking-grade security and compliance, native mobile trading apps, long-term embedded engineering teams.
Case: trading platform and digital front door for a Swiss digital bank. The client is a digital-only Swiss bank with no branches, so web and mobile are its only channels. In 2020 it relied on a single engineering vendor and wanted more capacity, and strict Swiss rules on security and data privacy set a high bar.
Intellias started with 1–3 engineers on digital onboarding. After six months it moved into more areas, and today 32 engineers work in five squads: onboarding, trading and pricing, customer data for AML and KYC, eBanking, and mobile trading. The trading platform reaches about 30 stock exchanges in North America, Europe, and Asia, with a focus on stocks and commodities. Intellias was also the first vendor to bring mobile engineering to the bank. It started with a free proof of concept to show it could meet the security rules. The stack is Java, React, TypeScript, Swift, and Kotlin.
The published results: 5 core banking products built, about 30 exchanges reachable, and six years of partnership so far. The case doesn't share conversion, cost, or performance numbers.
CHI Software
CHI Software was founded in 2006 and is headquartered in Limassol, Cyprus, with about 600 specialists and offices in Ukraine, Poland, Spain, and the US. It works across many industries, fintech included, and runs its own AI R&D center.
CHI Software’s strengths: legacy system modernization, cloud and microservices architecture on AWS, faster release pipelines.
Case: trading management platform for an alternative investment manager. Not every trading platform faces retail traders. This one is an internal tool for a global alternative investment manager working in real estate, hedge funds, private equity, and credit. Its trading workflows were split across several systems, which slowed decisions and added manual work and risk.
CHI Software rebuilt the platform around the full order lifecycle: shared work queues, instrument selection, capital allocation to funds, trading restrictions, and staged approvals. Admins can change UI fields without code changes, data syncs in real time, and every action goes into an audit trail with who, when, and the before and after values. Under the hood, the team moved the system to microservices on AWS, upgraded it to .NET 8, and set up CI/CD with automated rollback. The stack also includes Angular, SignalR, SQL Server, Terraform, and IBM MQ.
After about 5 months of work, CHI Software reports 60% faster performance under peak load, 5x better scalability, and half the lead time from commit to production. The client says user satisfaction went up 40%.
How to Choose a Custom Trading Platform Development Partner
Case studies help, but only if you read them with your own product in mind. Here's what to check:
-
Match the case to your market. OTC desks, retail CFD brokers, crypto exchanges, and fund trading desks have very different needs. A partner who built a retail stock app may not know how an interdealer negotiation works, and the other way around.
-
Decide between white-label and fully custom. Building on a ready platform, like Devexperts did for Deriv, gets you to market fast. A custom build takes longer but gives you full control of the code and the roadmap. Ask who owns the source code at the end.
-
Ask for real performance numbers. "Low latency" means nothing on its own. Ask about orders per second, matching latency, and how the system behaved at peak load in a past project.
-
Ask about compliance and integrations. Trading platforms connect to market data feeds, liquidity providers, payment rails, KYC tools, and back offices. Ask which ones the team has connected before and what went wrong.
-
Check how they handle small starts. Many trading products begin as an MVP for a narrow niche. IT Craft, one of the best custom trading platform development companies, took that route with Predira: it started with a small team, reused proven OTC know-how from Limpid Markets, and grew the product only as user interest came in.
-
Check whether they stay after launch. Markets change, regulators change rules, and traders keep asking for new features. Intellias has worked with the same Swiss digital bank since 2020 and grew from a few engineers to 32.
-
Talk to references. A short call with a past client tells you more than any case study page.
