ABOUT US

AI is making access infinite. Agents can send thousands of messages, generate endless content, and automate outreach at scale. Which means cold access is collapsing.

In a world where anyone can reach anyone instantly, trust becomes the only scarce resource. Hiring will happen through trusted referrals. Customers will come through warm introductions. Fundraising will happen through networks. Opportunities will flow through people who can vouch for you. The future of opportunity runs on trusted paths between people.

We are building the infrastructure for that world. The company is building an agentic Trust Graph: an AI system that maps your real connections and acts as the orchestration layer for your network. It understands who you know, how well you know them, and who can introduce you to the people that matter based on what you're looking for.

The tech challenge is huge: building systems for real-time context ingestion, identity resolution, intent modeling, and agent coordination at scale, across infra, graph systems, and applied ML.

Who We Are

The founder has spent the last decade scaling startups from 0 to hundreds of millions of users, leading growth, ops, and product — early at Rappi ($7B) and Lazada (acquired by Alibaba for $1B). The team is 4 people, 3 out of 4 are ex-founders. Since launching in 2023, the team has built multiple products used by 2M+ people, reaching the top of the App Store several times. The company has raised $8M from leading investors including Sequoia, Khosla Ventures, and OpenAI, and currently has 250,000+ people on the waitlist. A leading venture investor is personally involved in the company.

About the Role

We are looking for a Founding CTO, someone who wants to be the company's technical co-pilot. You will start hands-on, ship fast, and own the core architecture. As the company scales, you will be in charge of building the engineering team in SF.

This is not a VP Engineering role. We do not want someone who manages from a distance. We want someone who codes every day, is obsessed with what is happening on the bleeding edge, and has the potential to coach and grow a team around them. You will own the technical vision, partner directly with the founder on product and company decisions, and build the foundation that scales from 0 to 10M+ users.

Our Philosophy

Small teams build the most important products. Talent density over team size.

Extreme ownership and intensity. Speed over process.

Taste matters.

Human interaction is one of the most complex systems in the world. AI finally makes it possible to structure and orchestrate it at scale — this is one of the most important problems to solve.

Everyone on the team is here because they are obsessed with building.

Key Responsibilities

• Own the technical vision and architecture end-to-end
• Work across the full stack: backend, infra, data, and LLM-powered systems
• Ship fast, iterate on feedback, and get product into users' hands quickly
• Build the technical foundation that can scale from 0 to 10M+ users
• Recruit, mentor, and eventually lead an exceptional engineering team in SF
• Partner with the founder on company-defining product and technical decisions
• Lead the gradual transition of the engineering center of gravity to SF

Requirements

Must-Have

• 5+ years of engineering experience with a strong backend and infrastructure background
• Shipped ambitious products end-to-end with real battle scars from scaling
• Ex-founder or first engineer at a YC startup or equivalent track record of ownership
• Experience with AI/LLM systems, search, recommendations, or large-scale consumer apps
• Product sense: designs with the user in mind, not just technical correctness
• Comfortable with ambiguity, speed, and early-stage chaos
• Wants to grow into a true CTO role, not just writing code but building the team, culture, and long-term architecture
• Based in or willing to relocate to San Francisco, fully in-person in SoMa

Nice-to-Have

• Experience with graph systems, identity resolution, or large-scale unstructured data
• Familiarity with real-time data pipelines or agent coordination systems
• Prior experience recruiting or mentoring junior engineers
• Experience building consumer products at scale

Summary Requirements

• Zero-to-one product building experience
• AI and data infrastructure depth
• Founder mentality and extreme ownership
• Graph or large-scale data systems experience
• Team building potential
