A Bit About The Team

Torch team is an engineering team building LLM-powered products for Content and brand intelligence. We own two domains:

• AIO (Brand presence, serenity, prompt tracking) - measuring and improving how brands show up across AI/LLM answers (ChatGPT, Gemini, Perplexity, Google AI Overview). Think "SEO analytics for the AI-search era," without relying on classic Google rankings.
• Content - AI-driven content scoring, SEO/GEO guidelines, and content-generation suggestions.

We run large-scale data pipelines that turn raw LLM/SERP responses into trustworthy brand-visibility metrics. Cost-efficiency at scale is a core engineering challenge - we continuously benchmark and switch between LLM providers (OpenAI, Gemini, Mistral, Grok, Nebius, Claude) to balance quality and spend.
