Scope of work
01. Overview
CMG, a fintech startup connecting buy‑ and sell‑side participants in U.S. equity capital markets, needed a secure, scalable digital platform to streamline underwriting workflows and data analytics. OAK’S LAB optimized their MVP, built CMG XC™ and CMG DataLab™, and helped scale their engineering team, enabling CMG to serve 140+ buy‑side clients managing $40 trillion+ and 20 sell‑side partners covering 70% of market activity.

02. About client
Founded in 2015 by Greg Ingram, Mike Wilcox, and Stamo Hadjiyski, veterans of equity capital markets, CMG built a SaaS platform to eliminate outdated, manual processes across underwriting and investment workflows. CMG XC™ and CMG DataLab™ connect major banks, asset managers, and underwriters, providing real-time data, transparency, and collaboration on a centralized platform. Its user base includes over 140 buy-side firms managing more than $40 trillion, as well as nine of the top 10 U.S. asset managers. OAK’S LAB has been CMG’s software development partner since 2017.


03. Challenge
CMG’s early MVP, built by an outsourced team, faced critical issues around stability, performance, security, and workflow inefficiencies, unsuitable for rigorous financial institution requirements.
They needed an enterprise-grade solution capable of handling sensitive data at scale, enforcing compliance, enhancing user experience, and supporting both buy-side and sell-side integration.


04. Solution
We assembled a dedicated team of senior engineers to overhaul CMG’s platform.
Comprehensive codebase evaluation
We audited and refactored the existing MVP to meet enterprise standards of performance, reliability, and maintainability.
Security hardening
Built in secure development practices and compliance controls essential for regulated financial environments.
Modular architecture using React.js
Created clean, intuitive, and performant UIs that improved usability for both investment managers and underwriters.
Feature development of core products:
CMG XC™
A centralized workflow tool for managing public offering launches, order book creation, and allocation confirmation.
CMG DataLab™
Real‑time analytics dashboard delivering market intelligence, trends, and historical data for decision‑making.
We maintained ongoing collaboration with CMG’s internal product leadership, working closely to continuously iterate and deploy features that aligned with evolving market needs.

“In the initial phase of our engagement with OAK’S LAB, we needed high-quality talent to augment our development team. As our company grew, we started facing the challenge of scaling our team fast enough to build features that would meet the growing demands of our clients. In both phases, OAK’S LAB delivered."
