Stack
Next.js, TypeScript

Founding product engineer building an AI interviewer that runs follow-up-question conversations at survey scale. Work covers converting qualitative conversations into structured data with embeddings and fine-tuned LLMs, and a speech-to-speech pipeline. Stack includes Next.js, TypeScript, and large language models; the role owns products end-to-end.

Listen Labs

Everyone hates surveys. They’re tedious to fill out and give shallow data. That’s because they’re only a proxy for the real thing: conversations. Through a conversation, you can ask follow-up questions and get deep insights in a way that’s fun for the interviewee. Except you can’t have 1:1 conversations with everyone…

Listen Labs has built an AI interviewer that can ask follow-up questions, like a conversation, but at the scale and ease of use of a survey.


Technical Challenges


Turn qualitative data into quantitative insights

Listen Labs clusters free-form conversation into a structured format. This is not a trivial task. We use embeddings, fine-tuned large language models, and more to solve these problems.


Ask the right questions

Having a great conversation is not trivial. We’re fine-tuning and prompting in novel ways to get the right output from LLMs.


Multi-modality

We’ve built the fastest speech-to-speech pipeline but there’s a number of challenges we need to address to make it better. Our interviewer has audio input and output to the LLM and that’s tricky to get right.


Investors

There’s been $30B+ of market cap created from bringing surveys online. Our partner at Sequoia, [Bryan Schreier](https://www.sequoiacap.com/people/bryan-schreier/), was the first investor in Qualtrics – the $12B survey company.
