What are we building? Software was supposed to help us. Instead, it swallowed the working day. Everywhere you look people are buried under the burden of software. We are starting with automating email, turning it from a burden into a powerful competitive edge for people who grow businesses and build a reputation in their inbox. Think real estate, consultants, recruiters - people who spend hours on emails, scheduling, and follow ups. Unlike other startups, we're a pure-play applied AI company and not a SaaS company with AI features hastily bolted on. We use the best techniques (fine-tuned open-source models, tool use, and retrieval-augmented generation), and as a result, users send 53% of the email drafts we generate. How has it been going? From $1M to $25M ARR in the last 10 months, making us the fastest growing startup ever in the UK. We are backed by top-tier investors including: Marc Benioff (Founder of Salesforce), Harry Stebbings (Founder of 20VC), Douwe Kiela (Founder/CEO Contextual AI/Creator of RAG), David Singleton (Former CTO of Stripe), Des Traynor (CTO Intercom), Madrona (First Investors in Amazon/Snowflake). What do we value? We're very intentional about adding new people. We believe a small team of exceptional people working hard at a problem they care about will always outperform a larger, more unfocused team. That means you'll need to bring an intensity to this role that might not be expected at other companies but it also means you'll be fast-tracked into roles with greater responsibilities far earlier.
