About the project

MarinerCRM is a buy-side industry web application built to support investment firms in managing client relationships, internal workflows, and data-driven decision-making. The client needed a clear shift in how the platform looked, functioned, and communicated its value, moving from a functional system to a polished product that feels intuitive and professional for daily use.

We redesigned and enhanced the platform using React, Python, HTML, CSS, and JavaScript, focusing on usability, structure, and performance. The interface was refined to present complex CRM workflows in a more digestible way, while backend improvements ensured stability and efficiency. Every update was aimed at helping users navigate data confidently, understand platform capabilities faster, and work more effectively within a buy-side investment environment.

Feature Set of Mariner CRM

Multi-Layered Portfolio & Deal Pipeline Engine

We created a structured portfolio and deal pipeline engine to assist teams in clearly managing various investments, phases, and transaction flows.

Role-Based Workspace With Secure Data Segmentation

A role-based workspace was developed to ensure that users only access relevant data, while also promoting strong security and organized cooperation.

Custom Workflow Automation for Investment Lifecycle

Custom workflows were created to automate important phases of the investment lifecycle, minimizing manual effort and increasing operational efficiency. This reflects our experience in development for complex business processes.

Real-Time Financial & Performance Dashboards

We have developed real-time dashboards that offer financial indicators and performance insights in an understandable, actionable format for decision-makers. This highlights our experience in building custom web application development solutions for data-driven platforms.

Secure Document Vault With Versioning

A secure document vault with version control was set up to safely store, manage, and track critical files across teams.

Our platform needed a shift, and WeDoWebApps guided that shift with clarity. They improved how MarinerCRM looks, works, and communicates its value. The result is a much stronger version of the product and a better experience for our clients.
