Open's story

Learn more about Open

‍

Open is a trusted ESN partner and an industrial player in innovation, supporting major private and public organizations in their IT & Digital transformation, including TMA (Third-party application maintenance), in order to increase their competitiveness.

Some public-sector contracts for which Open is a holder require the production of commercial proposals following a strict formal framework, meeting specific requirements and SLAs. Every call-off answered late or incomplete is revenue left on the table. To meet these expectations while reducing repetitive workload, Open chose to collaborate with Cobl (formerly Thinkeo) to accelerate the production of commercial proposals and thus ensure that every call-off gets a consistent, high-quality answer, on time.

Under the responsibility of Thierry Wawrzyniak, Engagement Executive at Open, within the governance unit for major public-sector contracts, the collaboration began with a clear objective: produce faster, with minimal manual effort, while preserving human expertise.

Repetitive documents and strict formal requirements

Discover the challenge

In the market overseen by Thierry, the same types of documents must be generated regularly, with rigorous formatting and consistent quality.

"We always have the same formal framework, the same documents to produce,” explains Thierry. “The content varies depending on the subject, but the expectations remain the same: a precise, complete, and flawless format.” These documents are essential to ensuring Open’s commitments to its clients.

The team needed to:

produce documents quickly,
maintain a consistent structure,
reduce repetitive formatting and rewriting work,
allow engineers to focus on analysis and context.

Integrating AI into its processes and relying on Cobl to quickly generate documents

During the search for a solution, two priorities emerged: speed and reduced human intervention. Cobl stood out thanks to its no-code approach, requiring no development skills. This simplicity enabled rapid deployment and immediate adoption by the team.

“We needed to produce within short deadlines, with as little human intervention as possible and focus on value. We did not want to involve development or AI experts. The solution appealed to us because it is no-code: anyone can use it.”

Every call-off answered in the imposed format, on time

Our expectations and reason for collaboration

Today, we use Cobl to generate the commercial proposals required as part of responses to public-sector RFPs. These proposals cover different scenarios across the AMOE lifecycle:

design phases,
full build phases,
TMA activities.

“The solution adapts to the context,” specifies Thierry. “In addition to structuring the document, Cobl provides a critical analysis of the input elements, helping engineers validate the relevance of their choices.”

Faster, one standard, experts back on the client

The benefits are already visible.

A significant time gain

“We usually spend two to three hours producing a proposal from scratch. With AI, we get a version in just a few minutes, and the rest is contextualization, which remains manual and focused on the value delivered by the Sales and Delivery teams. Within one hour, the document can be produced.”

This represents a 50% reduction in production time.

Standardized quality

Open receives content from multiple sales teams, often heterogeneous.

“Quality is a real issue. AI smooths it upward.”

The AI also provides critical feedback on the choices provided as input.

Human expertise refocused on what matters most

“All the heavy work of formatting and synthesis is done by AI. Engineers then adapt the document to the context.”

Extending the collaboration to other teams

Open aims to continue structuring and expanding the use of Cobl across other markets and teams, with the goal of deploying a unified document workflow based on centralized, reusable content aligned with client expectations.

Throughout the collaboration, Cobl remains aligned with Open’s operational reality: producing precise, compliant, and high-quality documentation while maintaining expert control at every step.
