Helping Evalion Go from Idea to Initial Product Vision in 3 Weeks

Evalion, an early-stage venture focused on voice agent quality assurance identified a critical gap in the tooling available for testing AI voice agents. The founder sought support to shape the idea into a tangible product vision and a working prototype. Applying their expertise in voice agent development and workflow automation, Agent Studio helped the founder shape the concept, define the solution, and deliver a working prototype, accelerating the journey from idea to MVP.

Client

Evalion is an early-stage startup addressing a well-known yet underserved challenge: testing AI voice agents in a reliable, scalable way. Despite the increasing use of voice agents, the market lacked high-quality testing platforms. The founder recognized this gap and engaged Agent Studio during the inception phase. We supported the definition of the opportunity, helped shape the concept, and produced key foundational assets—prototypes, backend flows, and documentation—that enabled rapid early progress.

The launch version of Evalion was developed by their internal team in collaboration with five enterprise clients, including two unicorn agent builders. The company has already signed several client contracts. Evalion is backed by AI leaders from Meta, OpenAI, Google, Vercel, Reddit, Asana, and others.

Objective

The goal was to move fast from a loosely defined opportunity to a concrete definition of a first version that could be used to validate the concept, attract collaborators, and initiate customer conversations. This included both a clickable prototype for the front-end and a functioning backend to simulate real workflows.

Work

Agent Studio organized the engagement in two parallel tracks:

Conceptual Definition and UX Prototyping

• Live and async sessions to clarify the problem space and scope the opportunity.
• Shared lessons from Agent Studio’s experience building and testing voice agents.
• Co-defined the initial feature set based on real-world testing needs.
• Validated Bolt.new as the ideal tool to create an interactive clickable prototype to support early validation and stakeholder conversations.

Backend Architecture & Workflow Prototyping

• Designed and built a provisional backend using n8n, simulating key testing workflows.
• Produced technical documentation and hosted a live session to explain backend logic and rationale.
• Ensured the backend could be easily modified by the founder, enabling future self-directed development.

Results

This short but high-leverage engagement allowed the founder to:

• Rapidly define and validate the MVP scope and initial UX flow.
• Deploy a provisional backend to test logic and simulate real scenarios.
• Build a high-fidelity clickable prototype to communicate the founders’ vision to prospects and collaborators.
• Accelerate learning and decision-making.

Conclusion

In just 3 weeks, we helped the startup move from a promising opportunity to a tangible MVP. With a working backend and a high-fidelity front-end prototype, the founder gained clarity and conviction, along concrete artifacts to spark conversations with potential hires, early customers, and future investors.
