At xdof, we're at an inflection point. Frontier labs are racing to build general-purpose robots, and high-quality training data is the bottleneck. We're building the foundation behind the foundation models – the data collection systems, operational capability, exabyte-scale data warehouse, and software toolchain – to help our partners drive the field forward.
Founded by UC Berkeley Robotics PhDs and MechEs, this is a team that executes across software, hardware, and operations faster than I can believe sometimes. This speed and ability to deliver has led to partnerships with many of the top players in the space.
We are not quite yet out of stealth, so not able to share more details here, but are so understaffed relative to demand that I'd like to start semi-public hiring ASAP.

Kinelo manages the new type of hybrid team that will emerge in the future: humans+AI working shoulder-to-“shoulder”.
Our first product helps human software engineering teams deliver more efficiently and more reliably by assisting in coordination and engineering management. But it’s built on a foundational layer that ingests data, knowledge, and process across communications and systems, exposing that to humans and AI alike.
Eventually, Kinelo will become a proper human+AI orchestration layer, managing entire companies, and our goal is to have Kinelo run Kinelo (we already dogfood it today).

Chestnut builds software insurance carriers actually run their business on. We replace legacy, manual distribution systems with real-time data, automated workflows, and AI-driven tooling in a space that hasn’t changed much in decades.
This is product engineering. We ship to real customers, operate what we build, and spend time fixing the sharp edges that show up in production.
You’d work on backend-heavy product features around onboarding, compliance, payouts, and integrations. A representative problem: building a commission payout flow that ingests messy carrier data, applies complex rules and hierarchies, explains results to ops, and executes payouts that must reconcile cleanly with finance—while handling holds, chargebacks, retries, and partial failures.
Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS, LLM tooling.
Roles:
- Senior Software Engineer – Product / Backend (https://jobs.ashbyhq.com/Chestnut/fbbb7601-3d31-48b4-8639-75...)
- Staff Software Engineer – Architecture & Scale (https://jobs.ashbyhq.com/Chestnut/f28c5ee5-12aa-4e7b-b0ea-f5...)

Engineers can't keep up with their production environments: dozens of services, dashboards everywhere, alerts firing constantly. The information to diagnose most issues already exists, but finding it takes longer than fixing the problem. And the more AI-generated code ships, the more services get deployed by people who won't be around to debug them.
Cleric connects to your existing observability stack, autonomously investigates production incidents, and tells engineers what's wrong. We're well funded with years of runway, a small team of AI and infrastructure veterans in SF, growing quickly. Stack: Python, Go, LLMs, Kubernetes.
Some of the problems we work on:
There's no test suite in production. When the AI says "the root cause is X," how do you verify that? You can't A/B test diagnoses. Ground truth labels don't exist. We build evaluation systems that track resolution outcomes over weeks and correlate fixes with diagnoses to build statistical confidence.
When something breaks, everything looks broken. Database latency spikes, five services throw errors, CPU goes up, logs explode. When an agent sees 47 anomalies at once, it needs to figure out which one is the root cause and which are symptoms, across systems with feedback loops, hidden dependencies, and non-obvious temporal relationships.
A single investigation might need six hours of metrics across 50 services, 10GB of logs, 10,000 distributed traces, the last 30 deployments, and the relevant runbooks. LLMs have finite context windows. What's relevant isn't known until you investigate. Getting retrieval wrong means wrong conclusions or exploding costs.
We're hiring:
- Staff Software Engineer, AI: You build the core agent. Reasoning, evals, self-improving feedback loops. You debug agent behavior by tracing reasoning and tool choices to understand why the agent made a specific decision. You build the systems that make a non-deterministic agent reliable, and push it to handle increasingly complex incidents.
- Staff Software Engineer, Product: You define what an AI SRE should actually be. When AI handles the reasoning, how do engineers stay sharp for cases it can't handle? How do you build trust when someone needs to verify agent conclusions at 2AM? You answer these by embedding with customers during real incidents, running experiments, and making the technical calls to ship what works.
- Software Engineer, Backend: You build and scale the investigation platform alongside our senior engineers. Integrations with Datadog, PagerDuty, and dozens of observability tools. Agent reasoning pipelines. Runtime systems that handle real-time data streaming at scale. You'll ship customer-facing functionality across the stack.
- Founding Marketer: Software engineers are allergic to AI hype. Our users already love the product. The challenge is reaching the next thousand teams without setting off their BS detectors. You build the marketing function from scratch: programs, pipeline, infrastructure. You need a technical foundation and the ability to hold a 30-minute conversation with a platform engineering lead without getting lost.
- Staff Designer (Remote): The interfaces for AI agents don't exist yet. How do you make autonomous reasoning legible without overwhelming? You own design across brand, product, and marketing, defining the visual language for a new category.

I'm founder of Vidably and just closed a $1.5M pre-seed last week.
AI agents are about to orchestrate trillions in commerce, but today they shop on thin data: product specs, studio photos, and text reviews. Agents need evidence, not marketing. Today, the most influential product evidence lives on TikTok and Reels, outside the surfaces brands control and agents can use. Vidably puts verified buyer video directly onto e-commerce product pages through a lightweight widget. We capture that video post-purchase and link it to real purchasing outcomes. Every video is SKU-linked and structured so shopping agents can reason over it.
We're already seeing organic pull from creators and expansion from brands.

We’re hiring an Enterprise AE to scale Parabola, a product used by finance and ops teams to automate messy, high-stakes workflows without needing engineers.
Parabola sits at the intersection of AI, automation, and real operational pain: unstructured data (PDFs, emails), brittle processes, constantly changing rules, and teams that can’t wait months for IT. Customers get to see live workflows in action immediately.
This is not a traditional enterprise sale... Deals are driven by automations, as they are built live in-app. Customers engage multiple times per week and see value instantly. Expansion is natural because the product is horizontal, the first team is never the last
We’re looking for someone who loves going deep on product and customer problems. You can work comfortably with operators and execs (CFO/COO) as well as with companies in the retail/ ecom/ CPG + freight/ logistics spaces. You care deeply about solving real problems. We're building the Enterprise motion, not just running a playbook.
Parabola had its biggest year ever in 2025. We’re consistently exceeding targets, and there is serious demand that is pulling us upmarket. You’d be working closely with our CRO, COO, CEO and GTM team to shape how Enterprise sales is done here. If you’re an experienced AE (5+ years in SaaS sales) who wants to sell something genuinely powerful with real customer impact, we’d love to talk.
