​Codex Founder Feedback Session - San Francisco

​A curated, invite-only session for YC technical founders, CTOs, founding engineers, and serious builders who are already using or actively evaluating Codex and AI coding tools.

​This is not a generic mixer and not a rushed hackathon.

​The goal is to bring together a small group of high-signal technical founders for a focused conversation about how AI coding tools are actually being used in real startup workflows: what works, what breaks, what slows adoption, and what could make Codex more useful for fast-moving teams.

​Who Should Attend

​This session is designed for:

​YC founders, technical founders, CTOs, founding engineers, product-minded builders, and early-stage teams who are actively building with AI coding tools or seriously evaluating them for their engineering workflow.

​This is especially relevant if you are:

• ​already using Codex or other AI coding agents

• ​building a product where engineering speed matters

• ​experimenting with AI-assisted development workflows

• ​managing a small technical team

• ​trying to understand where AI coding tools help and where they still fail

• ​interested in giving direct feedback from real startup usage

​Why This Session

​Most events about AI coding are either broad community meetups or short demos.

​This session is different.

​Before the event, we will collect attendee questions, workflows, pain points, and adoption blockers through the registration form. This allows the conversation to be more focused, practical, and useful for both founders and the Codex/OpenAI side.

​The goal is to create a real feedback loop from serious technical users, not just a casual networking evening.

​What to Expect

​Expect a focused, high-signal evening with:

• ​light founder talks from teams already building with Codex / AI coding tools

• ​practical discussion around real engineering workflows

• ​structured Q&A

• ​optional office-hours style conversations

• ​curated founder-to-founder networking

• ​direct feedback collection around Codex usage, pain points, and adoption blockers

​Potential Codex/OpenAI involvement may include a short workflow demo, a “how we use Codex” talk, structured Q&A, or office-hours style conversations, depending on availability and what is realistic.

​You Will Leave With

• ​sharper insight into how other founders are using AI coding tools

• ​practical ideas for improving your own engineering workflow

• ​new connections with technical founders and builders

• ​a chance to share direct feedback about Codex and AI coding adoption

• ​a better understanding of where AI-assisted building is going next
