Growth Product Manager - Staff/Principal-level

Synthesia CEO Victor Riparbelli discussed the company's new Sessions product with Jon Fortt. Sessions transforms Synthesia's studio-quality AI video into interactive conversations with avatars. The product's initial application targets sales training. Employees watch instructional videos before role-playing with an avatar customer and receiving performance scores. According to Riparbelli, 78% of learners retry the role play, with 83% showing improvement. Synthesia has also launched an API. Riparbelli argued that most enterprise deployments no longer require a frontier model, suggesting smaller, more specialised AI systems can handle typical business use cases effectively.

Journalist creates interactive digital avatar of self with Synthesia. Synthesia, a London-headquartered digital avatar startup valued at $4 billion, has expanded its enterprise offerings with personalized interactive AI avatars, recently demonstrated through a pilot project with a TechCrunch journalist. Following the company's September opening of its New York office, the journalist collaborated with Synthesia's corporate affairs team, led by Alexandru Voica, to develop a fully customized digital twin. The process involved capturing facial imagery and voice samples in a dedicated studio, after which Synthesia deployed a multi-model technology stack combining voice-to-text transcription, agentic large language models, text-to-speech synthesis, and proprietary video animation to create three distinct avatar variants. The interactive avatar was specifically trained on the journalist's reporting regarding venture-capital-backed startup fraud, strictly limiting its responses to that predefined knowledge base. Testing revealed high fidelity in voice replication and deterministic behavior, with the system successfully redirecting off-topic queries back to its core parameters. While testers noted a mildly uncanny realism, the technology proved functionally robust, underscoring Synthesia's broader commercial strategy. The company, which surpassed $100 million in annual recurring revenue last year, currently serves enterprises through three primary product lines: scripted video production platforms, interactive roleplay modules for employee training and sales coaching, and an open API enabling third-party integration of its synthetic media models. This pilot highlights a shifting corporate landscape where AI avatars are transitioning from experimental novelties to operational tools. Organizations are increasingly leveraging the technology for scalable customer service, public relations representation, and immersive learning environments. However, the deployment also surfaces ongoing concerns regarding media authenticity, data consent, and the preservation of human trust in automated communications. Industry observers note that while deterministic avatars offer predictable, brand-safe interactions, more open-ended models risk generating hallucinations or overstepping ethical boundaries. Despite initial skepticism, particularly among demographics accustomed to traditional media formats, corporate America is rapidly integrating synthetic personalities into daily workflows. As the technology matures, the boundary between human representation and algorithmic automation will continue to narrow, requiring clearer frameworks for transparency and user consent in an increasingly digital ecosystem.

Journalist creates interactive digital avatar with Synthesia AI. 2026-09-26 07:04:17 Key takeaways. * Synthesia created an interactive digital avatar for a TechCrunch journalist in September, marking the first journalist to receive treatment outside founder Alexandru Voica. * Synthesia achieved four billion dollar valuation and surpassed one hundred million dollars in annual recurring revenue this year. * The journalist's deterministic avatar consistently redirected unrelated questions back to her trained venture fraud article regardless of topic. When Alexandru Voica, head of corporate affairs at video-generation startup Synthesia, sent a link this summer to an interactive virtual avatar of himself trained to answer press questions, it marked a new frontier in AI-powered public relations. The avatar represented what one journalist called "the final boss of using AI in PR" - beyond simple AI-generated text pitches to a fully interactive digital spokesperson. Synthesia, a digital avatar startup that hit a $4 billion valuation earlier this year and crossed $100 million in annual recurring revenue, invited the journalist to its New York office in September to create her own digital twin, making her the first journalist to receive this treatment outside of Voica himself. Synthesia creates first journalist digital avatar. Synthesia created an interactive digital avatar for a TechCrunch journalist, trained specifically on her story about venture-backed startups committing more fraud than non-VC-backed startups. The avatar was built to answer only questions related to that particular article. To create the avatar, the journalist entered a mini film studio inside Synthesia's office where the team captured numerous photos and a two-minute voice recording. The process resulted in four versions: personal avatars with and without glasses that read scripted content, and interactive avatars with and without glasses capable of responding to questions. Technical architecture behind interactive avatars. Synthesia's interactive avatars operate through a combination of voice-to-text, video, language, and text-to-voice models. The tech stack includes Synthesia's proprietary video and voice models, though the company allows customers to choose alternatives from labs including Cartesia, ElevenLabs, Google, or OpenAI. The system works through four stages: voice-to-text conversion of user questions, an agentic language model that processes text and determines actions, text-to-voice conversion for responses, and Synthesia's video model that animates the avatar during speech. Enterprises can host avatars on their preferred cloud infrastructure or use Synthesia's hosting services. Synthesia builds three types of products for different use cases. The first is a video-creation and distribution platform with classic avatars where users input scripts for the avatar to repeat. The second is an agentic platform called Sessions where users interact with avatars in surveys or roleplay scenarios, such as employees practicing sales pitches with AI avatars that respond and score their performance. The third is an API platform allowing developers to combine Synthesia's video and voice models with other technology services to build custom interactive avatars or products. The company recently launched Roleplay Sessions, enabling employees to practice professional scenarios with interactive AI coaching. Journalist tests deterministic avatar capabilities. The journalist's interactive avatar demonstrated deterministic behavior, responding only to questions about the trained article on venture fraud. When friends and family attempted to ask personal questions about her life before TechCrunch or her New York neighborhood, the avatar consistently redirected conversations back to the venture fraud story. The journalist's mother tested the model by asking questions "only they would know" about her daughter, but the avatar maintained its programmed boundaries. Testers noted the personal avatar's voice accuracy was better than the interactive version, though both achieved sufficient likeness to be considered "creepy" by non-tech friends. Future implications for journalism and corporate communication. The experience raised questions about journalism's future relationship with AI avatars. One investor immediately rejected the idea of news presented by avatars, citing existing pushback against AI-generated content infiltrating social media and news platforms. The journalist emphasized that journalism's core value lies in human connection, storytelling, and research, with trust being the profession's foundation that cannot be outsourced to AI. However, she acknowledged potential appeal in corporate settings where digital clones could handle routine communications during holidays or vacations. The journalist predicted her generation, Gen Z, would struggle to adapt to digital twins despite their sci-fi appeal, though she found avatars less jarring than humanoid robots. Faq. What did Synthesia do for the TechCrunch journalist in September? Synthesia created the first journalist digital avatar by capturing photos and a two-minute voice recording at their New York office. The company produced four avatar versions - personal and interactive variants both with and without glasses - with the interactive version trained exclusively on the journalist's article about venture-backed startup fraud. How does Synthesia's interactive avatar technology work? Synthesia's interactive avatars use a four-stage technical process: voice-to-text models convert spoken questions into text, agentic language models interpret the text and determine appropriate responses, text-to-voice models generate audio responses, and Synthesia's video models animate the avatar's movements during speech. The system combines Synthesia's proprietary models with optional third-party alternatives from providers like OpenAI, Google, ElevenLabs, and Cartesia. What is the difference between deterministic and nondeterministic avatars? Deterministic avatars only respond with information they were specifically trained on, redirecting users back to approved topics when asked unrelated questions. The journalist's interactive avatar demonstrated this by consistently steering conversations back to her venture fraud article regardless of personal questions asked. Nondeterministic avatars would be powered by chatbots free to generate unrestricted responses, which the journalist suggested could lead to "AI psychosis" in users.
