Cargo is building the robotic delivery platform of tomorrow. You can think of us as an automated warehouse on wheels. After taking jobs at UPS and FedEx, we realized that the last mile was broken and parcel delivery needed a new approach. Although delivery volumes have grown 5x in the past decade, delivery vans are stuck in 1950 and today’s process is highly inefficient and injury prone. Our first product is the X1 Robotic Cargo Bay which reimagines the guts of every delivery van you see on the road, and saves hours of labor per day for each vehicle. Our vision is to fully automate the delivery chain with radically more efficient networks that reduce carbon emissions and congestion while enabling people and our planet to thrive. We’re looking for an unstoppable and versatile first hire to lead software development for the pilot launch of X1. You’ll then rapidly iterate alongside our CTO and test with our customers to develop a complete V1 product to kick off our next fundraise. You know how to build and deploy fast, and also how to structure robust systems that hold up to abuse and scale. Get ready, there’s lots to build :)

Warmo is a GTM Signal Intelligence Platform that helps B2B founders, agencies, and sales teams find high-intent prospects automatically. Instead of spending hours on manual research, Warmo monitors the live web for real buying signals - funding rounds, hiring surges, market expansions and surfaces the right companies, the right decision makers, and AI-written outreach angles.

Inventive AI is an AI-native platform that transforms how B2B companies respond to RFPs, security questionnaires, and due diligence documents. Sales engineers, solution consultants, and proposal managers are often buried under repetitive and manual work—cutting into time they could spend selling. We’re solving that with an intelligent agent that deeply understands your past responses and context, auto-generating high-quality answers tailored to each RFP. The result? More time for teams to focus on strategy, fewer missed deadlines, and significantly higher win rates. Founded by product and AI veterans from Google Brain and backed by early believers, we’re on a mission to bring peace of mind to every team dealing with complex RFP workflows. We’re a nimble team of 11–50 people, obsessed with quality, speed, and product-led growth. If you’re excited by the idea of redefining enterprise workflows with cutting-edge AI, come build with us.

We are a community-powered holding company on a mission to build an ecosystem of brands where the community has a real voice and a real stake. As a U.S. Public Benefit Corporation, our structure is designed for co-creation, not just consumption. We believe that the most resilient and beloved brands are built with their communities, not just for them. Our first venture is a next-generation Minecraft network that will serve as the launchpad for our model. From there, we will expand into new industries—from media to technology—by partnering with visionary leaders and empowering them to build their own companies under our umbrella.
