Agents of Change: An Interview with Cassius D’Helon, Product Manager at D-ID

AI agents

As we launch D-ID agents, we wanted to share a product manager’s perspective on developing AI tools and the considerations for bringing them to market. Read this exclusive interview with Cassius D’Helon, the visionary Product Manager at D-ID who helped develop Agents. We’ll explore the product’s journey – from its inception to its debut, and gain insights into the challenges, innovations, and future of this groundbreaking technology.

From Concept to Market:

D-ID: Can you tell us about the journey of this product from concept to market?

Cassius D’Helon (CD): Agents transformed from a concept into a market-ready product in a remarkably short timeframe of 3 months through a highly focused and intense process. This journey was fueled by a robust vision, cross-functional collaboration, and strategic decision-making. The concept sprang to life by identifying a market gap for a face-first conversational AI video platform that can deliver a natural and engaging user experience across a broad spectrum of use cases. With a clear vision in mind, I defined the core features, emphasizing natural interaction, user customization, and adaptability to diverse scenarios.

The collaboration among developers, designers, and NLP specialists was pivotal as they worked together to ensure that the technical and design aspects of the product seamlessly complemented each other. Embracing an agile development approach, the team rapidly iterated on prototypes, incorporating valuable user feedback and making swift adjustments. Key features were strategically prioritized, leading to the creation of a functional MVP within the ambitious three-month timeframe.

Rigorous testing was done with a select group of users to collect initial feedback on usability, avatar interactions, and customization features. Guided by user insights, the team embarked on an iterative refinement process for the Agents platform, which involved addressing usability issues, elevating avatar responses, and enriching customization options to align with user preferences.

Distinctive Edge: What Sets Agents Apart

D-ID: What sets this product apart from its competitors in the market?

Cassius: Agents stand out with their high-quality natural AI avatars and extensive customization options. Users can personalize these agents in appearance, role, and knowledge base, offering a unique user experience unlike any other in the market. 

D-ID: How does this product align with the current trends and future directions in AI technology?

Cassius: Agents is at the forefront of the trend towards voice-first applications that rely on conversational interactions. We are entering a new market with the addition of photorealistic avatars and anticipate rapid adoption once the world learns of these capabilities.

D-ID: How do you envision this product impacting its industry or consumer behavior?

Cassius: I aim to set the highest quality standard for natural conversational experiences. A Natural User Interface (NUI) requires that agents adapt to human communication patterns rather than forcing users to conform to rigid computer systems. This approach will transform the way consumers engage with technology.

Identifying the Ideal User

D-ID: Who is the ideal user for this product, and how does it cater to their specific needs?

Cassius: Currently, the ideal user for Agents is still being defined. Our beta release is a discovery phase, where we’ll learn about the types of agents users create and how they meet specific needs. We have some assumptions, but like in other D-ID projects expect to be surprised by our users’ ingenuity and creativity.

Technical Challenges and Solutions

D-ID: What were the major technical hurdles in developing this product, and how were they overcome?

Cassius: One major challenge was minimizing response time for near real-time interaction. Our development team focused on streaming video and audio efficiently. We’re continually exploring innovative approaches to be implemented in future product iterations to close the gap with natural response times.

D-ID: Can you describe a feature you’re particularly proud of and the thought process behind it?

Cassius: I’m particularly proud of our use of RAG (retrieval augmented generation) to build a knowledge base from user documents, which is stored in a vector db. This feature ensures the model accesses recent or exclusive information, significantly reducing hallucinations common in LLMs.

Future Plans: Enhancing Agent Interactions

D-ID: What are the plans for future updates or iterations of the product?

Cassius: Future updates will introduce multi-modal interactions with agents, moving towards agents that seamlessly integrate with users’ needs.

Advice for Aspiring Product Managers

D-ID: What advice would you give to aspiring product managers who want to bring successful tech products to market?

Cassius: Dream big, stay lean, and continuously learn and adapt as you build. It’s the key to bringing successful tech products to the market.


Cassius D’Helon’s journey with Agents is a testament to the power of vision, collaboration, and user-centered design in the realm of AI and technology. As D-ID continues to push the boundaries, Agents is poised to redefine our interactions with technology, making them more natural and engaging. Stay tuned as we witness the unfolding of this innovative era.
