Koragence designs and develops your business software, web applications, and SaaS platforms. From Paris, we support projects from defining the need through day-to-day operation.
Scoping, architecture, design, development, and integrations: we coordinate the expertise your project needs, then support production launch, maintenance, and future changes.
Based in Paris, in the 8th arrondissement, Koragence is an IT services company specializing in custom software development. We lead projects from France and bring together experts and partners suited to their functional and technical requirements.
You entrust us with a project, not only its development. We coordinate contributors and delivery steps through integration into your information system and ongoing maintenance.
Are you preparing new software or the redesign of an existing tool? Let’s discuss your objectives, constraints, and information system to define an initial technical approach and the elements needed for an estimate.
Discussions with business teams and the IT department are essential when scoping software. Our presence in Paris facilitates workshops, process analysis, and technical decisions, especially when several departments are involved.
This proximity comes with structured remote follow-up. Documents, designs, code, and the roadmap remain accessible for approvals and progress tracking. The working model adapts to your organization, with in-person meetings at the stages that require them.
We design your software with its future operation in mind. Architecture, integrations, documentation, and maintenance are addressed from scoping to prepare launch and support the evolution of your business.
We step in when your tools slow operations down: processes managed in Excel, scattered data, or software that is difficult to evolve. We then develop an application adapted to your business rules, users, and information system.
Tools to manage cases, organize approvals, and track activity around your business rules. Discover our business software development service.
We develop B2B platforms with account, subscription, permission, and administration management. Discover our support for web applications and SaaS.
Your clients and suppliers get a secure space for documents, requests, orders, and approvals connected to your tools.
Production, maintenance, quality, traceability, and metrology: our custom industrial software development expertise covers your equipment and field operations.
We automate processes, document workflows, and exchanges between tools with supervised assistants. Discover our business AI service.
We work with small companies, SMEs, mid-sized companies, groups, and public organizations. The team and working model adapt to your organization, project complexity, and existing capabilities.
We structure your operations with a first software product adapted to your needs.
We develop your business tools, portals, and integrations.
We modernize your applications and their integration into the information system.
We design applications around expected accessibility, traceability, and reversibility requirements.
We organize the project around validation steps defined with you. Intermediate releases let you check how the software works and adjust priorities before production launch.
We analyze your usage, processes, and tools to establish needs with the teams involved.
We define a first usable release, separating essential features from later improvements.
We identify the exchanges required with your ERP, CRM, DMS, accounting tools, and other services.
Designs let you validate workflows and screen organization before development.
Technical choices account for your information system, security requirements, and long-term maintenance conditions.
Features are delivered progressively to gather feedback and validate their fit with intended uses.
We test business workflows, permissions, integrations, and edge cases.
We prepare environments, access, backups, and monitoring before launch.
We train your teams to use the software and provide the necessary documentation.
We can provide fixes, updates, and improvements within a maintenance agreement.
You can contact us with a need to clarify, an Excel file, software to replace, or a few designs. Specifications can then be built with your teams.
We formalize business rules, workflows, and required integrations to define a development scope, architecture, budget, and roadmap.
We take over applications developed by other providers or internal teams. Reviewing code, architecture, access, and dependencies helps identify risks. Our project takeover approach establishes priorities before development continues.
Depending on the software’s condition, we can modernize the interface, refactor the code, migrate data or infrastructure, and make deployments more reliable. We assess gradual evolution before recommending a full rewrite.
We connect your software to ERP, CRM, accounting tools, DMS, payment, signature, email, SMS, and ecommerce systems. Integrations may include SAP, Salesforce, Sage, Cegid, Pennylane, Stripe, HubSpot, and Microsoft, depending on versions and available interfaces.
Discover our API integration services, Pennylane connectors, and developments for Cegid and Sage 100. We define data exchanges around your workflows and existing architecture.
We integrate AI for precise use cases: information search, data extraction, classification, summarization, or action preparation. Sources, access rights, and human controls are defined before integration. Our business AI service accounts for processed data and team responsibilities.
Security requirements are defined from the start: access rights, multi-factor authentication, secrets, dependencies, logs, backups, and testing. We prepare Cloud environments, monitoring, and CI/CD deployments with your infrastructure team or our DevOps and cybersecurity experts.
Your client space centralizes the roadmap, tasks, releases, documents, and meeting notes. It also contains specifications, invoices, and your feedback. Decisions and approvals are preserved so everyone shares the same view of progress.
The team is assembled around the project: project lead, frontend and backend developers, technical lead, designers, testing specialists, DevOps, cybersecurity, AI, and data. Our network of more than 50 experts and partners helps mobilize the right skills at each stage.
Our network includes professionals with backgrounds at EPITA, EPITECH, ESSEC Business School, HEC Paris, École Polytechnique, and CentraleSupélec.
We take responsibility for the decisions and work your project requires: functional scoping, architecture, design, and development. Your teams participate in approvals and keep visibility into choices while Koragence coordinates delivery.
Our Onctuo, Good is Merch, and Fileen projects illustrate work in different business contexts. Beyond delivery, we prepare the conditions for software maintenance and handover to support its use and future evolution.
A freelancer can address a focused need when you already have technical leadership. Koragence steps in when you want to entrust the whole project to one partner: skills coordination, development, design, testing, production launch, and maintenance under one delivery lead.
Koragence is an IT services company that takes software projects from scoping through maintenance. Beyond mobilizing profiles, we organize their work around a scope, schedule, and deliverables defined with you.
Software ownership, rights assignment, and reversibility are defined contractually. Code repositories, access, environments, and reference documents are organized to support project continuity and takeover under the agreed terms.
Budget depends on functional scope, integrations, and technical constraints. We review business rules, user profiles, data migration, security, and expected level of finish. The estimate accounts for the design, development, and deployment work required.
A focused internal tool, a SaaS platform, and a business ERP require different resources. See our custom software pricing guidance to prepare your budget and identify the main investment areas.
Tell us about your project, even if it is still taking shape. We will review the business need, users, existing tools, and schedule constraints to define the next step: scoping, development, or software takeover.
Proximity helps with workshops involving your teams and discussions with your IT department. We then organize follow-up between in-person meetings and remote work according to project needs.
Whether you have specifications, software to take over, or a need to clarify, let’s discuss your project. We will help define priorities and the scope to estimate for the next step.
