A consulting firm built on people.
RYLNA Consulting is an independent firm based in Paris. We help telecom operators and companies evolve their critical information systems.

Why RYLNA exists
Because complex systems need someone who sees the whole picture.
At an operator or a large company, the information system combines dozens of applications and suppliers. Each team knows its own scope. Nobody knows the whole chain any more.
RYLNA was created to take on that role: an architecture everyone understands, a programme that can be steered, an integration that can be proven to work.
How we see consulting
- Deliver, not just adviseAdvice is judged by what goes into production. We stay until go-live and stand by our choices.
- Say what we are good atWe work on telecom IT, Order-to-Cash and integration. For anything else, we say so and point you elsewhere.
- Leave your teams self-sufficientEvery deliverable is written so your teams can take it over without us.
Our specialisation
OSS/BSS architecture, the Order-to-Cash chain, catalogues, provisioning, billing, mediation, operator CRM, APIs and multi-vendor integration. Our consultants have worked for fixed, mobile and converged operators and for integrators, in France, the Pacific and Africa.
What you can count on.
Independence
We take nothing from vendors. We recommend what suits you, nothing else.
Seniority
The experienced consultants you meet are the ones who do the work.
Transparency
We write down our assumptions and our limits. Our references are shown as they are.
Confidentiality
What you share with us stays between us: your data, your projects, your decisions.
How we work with you.
Understand before proposing, propose before building, verify before delivering.
- 01
Understand
We meet your teams, study what exists and map the flows. We start from facts, not from a ready-made model.
- 02
Design
We propose a target and several scenarios. Each one is costed, with its risks written down in black and white.
- 03
Orchestrate
We set up steering and coordinate vendors and integrators. Everyone knows who is waiting for what, and by when.
- 04
Integrate & validate
Interfaces, end-to-end tests, acceptance. We prove it works before go-live, not after.
- 05
Hand over
Documentation, knowledge transfer, handover to operations. At the end, your teams can do it without us.
How we work with clients
- One point of contactThe person who scopes the engagement is the one who follows it through.
- Written commitmentsScope, deliverables and success criteria are set at the start and reviewed with you.
- Confidential by defaultWe only name a client with their agreement, and we publish no results without their approval.
The founder
OSS/BSS solution architect
President and founder of RYLNA Consulting
A telecom engineer and information systems architect, he brings more than 17 years of experience at the heart of telecom operators’ technology transformations.
His career, shaped by strategic projects at Orange, Ericsson and OPT New Caledonia, has given him deep expertise in OSS/BSS architecture, complex systems integration and Order-to-Cash process orchestration.
Convinced that a successful transformation depends as much on mastering technology as on understanding business stakes, he founded RYLNA Consulting with a clear ambition: to turn information system complexity into reliable, high-performing solutions that create value.
Experience gained with previous employers before the firm was founded.
Software
We build too.
Alongside consulting, RYLNA builds its own software, including Orchestraa Suite for telecom operators. Building and running it reminds us what our clients’ teams go through.
