Zencore needed a flexible, easy-to-use diagramming solution to streamline client proposals
As one of the fastest-growing Google Cloud consulting partners, Zencore regularly proposes in-depth technical solutions to existing and potential clients. To ensure all stakeholders (both internally and externally) can easily visualize the solutions being presented, Zencore makes diagramming a core element of its proposal workflow.
The problem? While diagrams help bridge the gap between developers and non-technical stakeholders, creating them was a long and tedious process for Zencore's internal teams. The legacy diagramming tools within each team's stack required manual drawing and delivered outputs that were difficult to modify for each client's proposal. Additionally, most weren't intuitive enough for Zencore's technical architects to use without friction, having been built to cater primarily to designers.
As these shortcomings began to extend proposal turnaround times, Zencore quickly identified the need for a solution that would accelerate diagramming without compromising quality of deliverables.
During the search for a solution, Zencore CTO and Co-Founder, Guilhem Tesseyre, discovered Eraser. After learning of the solution's ability to convert text-based AI prompts, scripts, schema, or code into client-ready diagrams in seconds, he gained all the conviction needed to move forward.
"Tools like Eraser abstract the complexities and time investment linked to diagram creation, which is very powerful for our teams."
Eraser's AI-powered diagramming workflows simplify cloud architecture visualization
As Guilhem had hoped, Eraser delivered the diagramming solutions needed for Zencore's internal teams to expedite proposal turnaround times while enhancing the quality of deliverables.
He attributes this success to several core benefits of the platform:
Seamless migration and setup
Within days, Eraser had established a testing environment for Zencore to acclimate to its new diagramming workflows. Upon validating that the platform could synthesize both written AI prompts and Terraform code into enterprise-grade diagrams in seconds, Zencore migrated its entire engineering staff to Eraser within a week. To further streamline onboarding, Eraser delivered on-demand support via a dedicated Slack channel, ensuring any questions were addressed before they became roadblocks.
AI-powered diagramming
With Eraser's flagship AI diagramming feature, Zencore's internal teams can generate comprehensive diagrams in seconds using plain language, Terraform code, a schema, or infrastructure script. Guilhem remarks that the greatest use case for this feature has been generating diagrams to showcase what a client's cloud architecture looks like before and after shifting to Google Cloud, as well as highlighting the steps to get there. He also adds that whenever a technical architect wants to propose changes, they can spin up a supporting diagram in seconds, significantly improving their chances of getting buy-in from stakeholders.
Effortless editability and iteration
Unlike the rigid and inflexible tools that preceded it, Eraser ensures all diagrams are editable by hand, empowering Zencore's teams to adjust layouts, add elements, or refine details without having to start over. This flexibility (combined with a simplified and user-friendly UX) makes it easy for technical architects to iterate and respond to ad-hoc project changes, preserving effort while eliminating duplicative work.
Enhanced internal documentation
The use cases for Eraser don't end with client deliverables. Guilhem personally uses the tool to enhance company documentation with diagrams that showcase each step within internal workflows. By supplementing text-based documentation with easy-to-digest diagrams via Eraser, Guilhem ensures each team member has the clarity needed to align on internal procedures and deliver the maximum value within their role.
"The impact of Eraser is actually twofold. We use it externally to present proposals to clients and internally to strengthen documentation by diagramming company procedures from sales support to marketing content generation. The platform's versatility is virtually limitless."
Zencore significantly accelerated proposal creation times while enhancing internal documentation
With Eraser powering its diagramming workflows from ideation to execution, Zencore transformed proposal design from a burden to its competitive advantage. Today, Zencore's technical architects generate client-ready diagrams 20x faster, and save a collective of 40 hours per month—time they can now reallocate toward more growth-focused initiatives.
As Zencore continues to expand in both solutions offered and client count, Guilhem is confident that Eraser will act as a crucial supporting tool within the proposal creation process.
"What really excites us about Eraser is how quickly their team innovates. They regularly push new features that align perfectly with our needs. We're always eager to see what they'll ship next."

Implementing Eraser sped up diagram creation by 10x... This efficiency gain, coupled with quicker updates to complex diagrams, has improved customer satisfaction.
"Since implementing Eraser, our documentation efforts have skyrocketed from just 4 documents to over 110 in just six months."
“Eraser has unlocked a 30% increase in developer productivity due to faster onboarding, better cross-functional collaboration, and less room for mis-communication.”
Use Eraser for all of your diagrams and docs
Beyond data flow diagrams, do you need to create other technical docs and diagrams like design docs, RFCs, network diagrams, and API diagrams? Eraser provides a single platform for modern engineering teams to collaborate on docs and diagrams.
