Vention’s role
Vention’s hands-on experience
Need to scale an engineering team
Your trading platform is up and running, serving customers, processing transactions, and driving revenue, but your internal team can’t keep pace with new features and third-party integration demands, as well as performance and security fixes and updates.
With 20+ years in financial tools and trading systems development, and expertise in event-driven architectures and real-time market data processing, Vention engineers swiftly join your teams and start contributing to your codebase without long onboarding cycles.
As StoneX's scope of work increased, the client scaled the Vention team to 70 engineers to support more than 330,000 active retail accounts across 180 countries.
Need to build a trading platform
You run a fintech startup and want to develop a new trading platform that will be compliant with FATCA, MiFID, AMLD5, KYC, or SEC/FCA from the first lines of code and leverage the latest market technologies for the utmost user experience and performance.
Whether it’s a retail multi-asset trading platform, a clearing system, an investment API, or a real-time analytics solution, Vention offers full-stack software development, designs high-performing, compliance-first architectures, and embeds AI for real-time data analytics.
In our work with fintech Altruist, Vention helped the client create a new revenue stream by building an event-driven self-clearing platform featuring advanced tools for monitoring potential errors and performance.
Need to modernize the existing trading solution
Your trading solution is falling behind the times with significant technical debt, or changing compliance standards require a ground-up redesign or re-architecture, and your current vendor can’t handle the potential amount of work.
Vention understands that every change to a financial application carries compliance risks. Whether it’s a platform migration to microservices, app redesign, performance optimization, or new feature development, Vention ensures step-by-step transformation so that your running trading platform continues processing operations throughout.
By rebuilding its three-year-old legacy solution with Vention engineers, Berlin-based financial startup Upvest scaled its investment API and has generated £80M+ (~$100M) in transaction volume.
Vention’s trading platform development services
Team scaling for trading platform engineering
Vention can scale trading platform engineering teams with specialists who work with live trading systems, real-time data flows, and compliance-driven architectures. Vention engineers understand the demands of operating financial platforms and integrate into ongoing delivery without a long learning curve.
Engineering support covers Go and Java backends, .NET services, market data pipelines, mobile trading applications, QA automation, and compliance-aware platform architecture.
- 20 Vention engineers joined Exness, a multi-asset brokerage service provider, and stayed with the client for three years, working on several software development projects with different timelines and scopes of work.
- Upvest doubled Vention’s team within the first two months of our engagement to build a Go-based B2B platform for share trading and fractional investments.
- TWINO, an investment platform provider, needed to scale quickly, and three Vention engineers swiftly joined TWINO’s team to work on a Vue.js and Nuxt-based project.
End-to-end regulated fintech product development
Vention builds regulated financial products, including custom trading solutions and brokerage systems, clearing products, and custodial platforms. We handle the development end-to-end, from platform architecture design, backend and frontend development to custom integrations, QA, and infrastructure setup, with SEC, FCA, FATCA, MiFID, and KYC/AML requirements built in, so compliance is always part of the system design rather than a last-minute patch:
- Vention helped Upvest create a scalable investment API compliant with key European regulations, including FATCA, MiFID, AMLD5, and KYC requirements.
- For Union54, Vention built an MVP of a serverless transaction-processing API in just three months.
- Vention developed a significant portion of StreetShares’ branded borrower application, which became the deciding factor in bringing on several of StreetShares' largest clients.
- Vention also supported an FCA-regulated digital securities platform, integrating user identity verification with NorthRow, as well as investor profiling and classification features.
We build trading platforms using Java, Spring Boot, Go, Kafka, Kubernetes, DynamoDB, PostgreSQL, gRPC, AWS (Lambda, ECS/EKS, RDS, S3), and Terraform.
Real-time trading infrastructure development
Vention builds scalable, interoperable, and highly available systems behind real-time trading platforms, including:
- Core trading platform components
- Order management and smart order routing
- Market data benchmarking and feed handling
- Execution support for strategies such as POV, TWAP, and VWAP
- Anti-fraud systems
To ensure a trading product feels credible to end users and trading professionals can trust the platform under load, Vention engineers design real-time infrastructures with low-latency data handling, dependable execution, and fault tolerance, and work with Java, .NET, Angular, WebSockets, Redis, ActiveMQ Artemis, Lightstreamer, SignalR, and R.
In our work for StoneX, Vention delivered a multi-asset platform that supports 20M trading inquiries per day across 180 countries. And for another trading client, Vention delivered an institutional EMS with real-time algo strategy resolution, market data benchmarking (notional, %ADV, IVWAP, spread), and order execution strategy defaulting.
Investment API and wealth management platform development
Vention covers trading software development for firms whose products span both client-facing investing tools and the operational and trading systems behind them. Placing strong focus on SEC/FCA, FATCA, MiFID, AMLD5, and KYC-compliance, Vention ships the core systems behind investment products, portfolio experiences, account infrastructure, and the operational tools your teams need:
- B2B investment APIs
- Portfolio management APIs and systems
- Market data APIs
- Trading and execution APIs
- Clearing infrastructure APIs
- Fractional investment platforms
- Robo-advisors
For instance, Vention helped Upvest build a Go-based B2B investment API for share trading and fractional investment on 19 microservices, enabling Upvest to successfully onboard 500K+ users in the test environment and generate £80M+ (~$100M) in transaction volume.
While for Vestwell, Vention scaled their workplace investment platform, which helped them achieve 200% growth and raise $70M in Series C funding.
Financial platform transformation and migration
Vention modernizes live financial platforms in phases, improving delivery without putting operations at risk. Our teams work with technologies such as Go, Java, Spring Boot, Vue/Nuxt, Angular, .NET, Kafka, PostgreSQL, Docker, Kubernetes, and AWS.
The scope of Vention’s modernization services includes, but is not limited to:
- Monolith decomposition and microservices migration
- Cloud migration
- AngularJS to Vue migration
- Test automation setup
- Architecture redesign
- Code refactoring
And Vention has already helped global fintech and trading leaders upgrade their systems and reenter markets with stronger and more reliable products:
- Vention upgraded StoneX’s backend with technologies like .NET, transitioned to a modular architecture, and revamped its flagship web solution, saving 64 days of testing per release through automation and enabling 100% automation of Salesforce account assignments.
- When TWINO received an Investment Brokerage services license, Vention helped the client redesign their web application to align with the new business model and offering.
- For Upvest, Vention maintained a three-year-old legacy investment API while rebuilding it as a new, scalable solution, resulting in $18M in Series A funding.

FAQs
Does Vention have experience building trading platforms?
Yes, fintech and trading are among Vention’s strongest areas of work. Vention’s largest engineering engagement across all verticals is with StoneX, a public company we’ve partnered with for 12 years. The engagement with StoneX spans 70 engineers and supports a trading platform that serves 330,000+ retail accounts and 32,000+ institutional clients across 180 countries through the Forex.com brand.
Vention’s also worked with fintech and trading-focused companies like Altruist (the first all-in-one custodian) and Upvest (an investment API with £80M+ in transaction volume). Across those engagements, our teams have supported products in forex, equities, CFDs, crypto, investment APIs, and algorithmic trading. Experience across these projects translates into a strong understanding of performance, scale, and the operational demands of modern trading platforms.
Do Vention engineers understand financial instruments and the trading domain?
Sure. Vention engineers work with order management systems, market data feeds, algorithmic trading strategies (POV, TWAP, VWAP), multi-asset routing, and regulatory compliance. Vention clients highlight our ability to provide engineers skilled in both the fintech domain and software development.
“What stood out the most about this company was their ability to rapidly understand our complex needs and deliver results with exceptional speed.” — Olga Dashkovets, Operations Manager at Exness.
Can Vention build a SEC/FCA-compliant financial platform from scratch?
Yes. At Vention, we incorporate compliance requirements from the project start, along with performance, security, and long-term scalability needs.
For instance, for Altruist, we built a regulated financial platform from the ground up that became the industry’s first all-in-one custodian. We’ve also supported Upvest’s investment API, built to handle regulatory requirements including FATCA, MiFID, AMLD5, and KYC across European markets.
Can Vention handle the performance requirements of real-time trading?
Yes, we’ve already built for the kind of speed and scale real-time trading demands. For example:
- For StoneX, our engineers supported infrastructure handling 20M trading inquiries per day.
- For Upvest, we helped onboard more than 500,000 users in the test environment.
- For Union54, we architected a serverless, event-driven transaction-processing system for high-volume financial activity.
We consider high performance from the start, selecting the right architectures, data flows, and scaling strategies, and opting for technologies such as Kafka for streaming, Redis for caching, WebSockets for real-time data, and Kubernetes for elastic scaling.
Can Vention help transform a legacy trading platform without disrupting live operations?
Yes. We’ve helped trading platforms modernize without risking live operations. StoneX came to us when its flagship web platform was falling behind, and we revamped it while the business continued to handle 20M daily inquiries.
We’ve done the same with other platforms, including Upvest, where we helped rebuild a three-year-old aging product into a scalable investment API without interrupting live operations. In each case, we kept regulatory requirements part of the delivery process from start to finish.
How quickly can Vention assemble a fintech engineering team?
We move fast. Candidate CVs are shared within 48 hours, and we can always scale teams to match the project scope. Vention provides access to 3,000+ engineers, which means we can bring in people with relevant experience, for example, in Go, Java, .NET, and financial infrastructure, and often from teams already working on similar systems.
For instance, our long-term partnerships enabled StoneX and Exness to scale dedicated Vention teams to 70 and 20 engineers, respectively.
What happens if an engineer leaves mid-project?
Knowledge transfer and documentation are always part of how we work, so you’ll never get engineer-locked.
At Vention, we value genuine partnership to ensure every client reaches their goals with a reliable software development partner nearby. StoneX has worked with us for 12 years, CoverWallet for more than eight, one financial services client for more than seven, and Vestwell for six. That kind of consistency comes from stable teams, clear documentation, and delivery processes designed to maintain momentum.
