We’re building the professional network for the AI age - think Perplexity meets LinkedIn, powered by expert-modeled AI profiles. Team is small (ex-Lyft, Whatnot, Pinterest, Eventbrite, ex-founders) and everyone codes (even our ops person). Our designer is cracked and ships production code regularly.

Supercede builds industry-leading risk placement and analytics software for the reinsurance industry. They favour asynchronous communication, hire 'managers of one', and support autonomy and responsibility.

Supergood generates and maintains unofficial APIs for products without them. Our customers use our APIs to unlock new customers of their own, and build previously inconceivable features without flaky browser automation nor engineering overhead. Supergood does this by combining our AI-powered product that automates reverse-engineering, with our in-house observability platform to ensure that every API we generate is reliable, robust and consistently maintained. We've raised $4mm in seed funding from top operators including Max & Nellie Levchin (CEO/Founder Affirm + Paypal) and Zach Perret (CEO of Plaid).

We’re building the fastest experience in the world for work email, team communication, and productivity platform of the future. We’ve built the fastest email experience in the world, and soon-to-be team communication and collaboration so professionals end each day feeling happier, more productive, and closer to achieving their potential. Teams have adopted us at Spotify, Netflix, Airbnb, Notion, Dropbox etc.

We generate full-stack apps and deploy them — a generated app becomes a live URL, on our infrastructure or in the customer's own AWS or GCP account. It’s in production and it has more shell script in it than it should. You’d own it, and the mandate is to make it boring. Kubernetes, GCP and AWS deploy paths, CI/CD, observability, cost, tenant boundary. No on-call rotation today — it’s the founders and whoever last touched it. Building a real one is part of the job, not something you inherit alone. 4+ years production infra, Kubernetes past the tutorial, AWS and/or GCP at depth. The rest is on the page, including the open problems that don’t flatter us. I’m a co-founder — ask me anything here.

We're building a self-improving IDE for running coding agents in parallel. Tens of thousands of engineers use it as their main IDE, at companies like Netflix, DoorDash and Wix. It’s source-available: https://github.com/superset-sh/superset. We’re 4 people, including 3 ex-YC CTOs. The work goes from the pty and stream transport up to the UI, all TypeScript.

Supper is a stealth mode startup ($10M in seed funding + 4 years of runway) offering the world's smartest AI/ML-driven business intelligence platform. This 15-person team is led by cofounders whose previous ventures exited via IPO and acquisitions to Lululemon & Plaid.

We are building notification infrastructure for developers.

We provide Python and Django apps and services.

Our mission at Surge is to build the human infrastructure behind the next wave of AI and LLMs. We’re building a data platform that powers AI teams at OpenAI, Anthropic, Meta, Google, and more. Reinforcement Learning with Human Feedback is the critical technique behind the new generation of AI assistants, and that human feedback comes from us. Our product has been a game-changer for the top AI teams in the world.
