SoFIX
AI-POWERED FIX AUTOMATION PLATFORM
FIX Onboarding. Automated.
Accelerate FIX connectivity, certification and onboarding with intelligent automation.
SoFIX is Sosuv's AI-powered platform for automating FIX certification, onboarding and related trading technology workflows. From processing complex FIX specifications and generating test cases to automated testing, validation and real-time progress tracking, SoFIX helps capital markets firms bring trading connections live faster, reduce manual effort and improve operational efficiency.

Why FIX Onboarding Is Still Hard
FIX is the industry standard for electronic trading connectivity, yet onboarding and certification remain manual, resource-intensive and time-consuming for many organisations.
1. The Specification Gap
FIX specifications often arrive as lengthy, unstructured documents. Interpreting requirements and translating them into configurations and test cases consumes valuable engineering time and introduces opportunities for errors.
3. The Coordination Gap
Certification involves multiple stakeholders across brokers, clients and technology vendors. Coordinating testing sessions, resolving issues and managing dependencies can significantly delay onboarding.
2. The Testing Gap
Manually creating test packs, executing certification scenarios and validating responses leads to lengthy testing cycles, inconsistent coverage and repeated effort.
4. The Visibility Gap
Without centralised tracking, teams struggle to monitor certification progress, identify bottlenecks and maintain consistent audit records across multiple counterparties.
What SoFIX Delivers
Specification Automation
Turn Complex FIX Specifications into Actionable Inputs
SoFIX uses AI-powered automation to process FIX specifications and technical documentation, reducing the manual effort required to prepare certification workflows.
It helps transform unstructured information into organised, machine-readable inputs for testing and onboarding, while also supporting specification-related FIXatdl workflows.


Test Automation
Generate, Execute and Validate Certification Tests
SoFIX automates certification test creation, execution and validation against supported trading systems and FIX simulators.
By reducing repetitive manual activities, it helps improve testing consistency, minimise coverage gaps and accelerate certification cycles, while allowing FIX engineers to retain oversight where required.
Certification Management
Real-Time Visibility Across Your Onboarding Pipeline
Centralised dashboards provide visibility into certification progress, test results, outstanding issues and audit records.
An integrated self-service portal enables counterparties to participate in supported certification activities and track progress asynchronously, reducing coordination overhead.


FIX Utilities & Integration
Simplify Troubleshooting and Work with Existing Infrastructure
SoFIX provides utilities for FIX log analysis, protocol reference, troubleshooting and technical documentation.
It is designed to integrate with existing FIX infrastructure, proprietary trading applications and OMS/EMS platforms through supported FIX connections and APIs.
