AO Labs is an applied AI research lab building real-time reinforcement learning, unlocking AI that can be hyper-personalized with less data than LLMs.
Our first product is an API that learns by combining end-user context, application data, and a feedback signal (eg. an end-users' likes and dislikes) in a fast learning loop that's lightweight enough to provision a distinct agent per-user. There's no gap between training and inference-- train at the edge, learn all the time.
With our framework we increase training efficiency and also combine the static pre-trained intelligence from LLMs with continuous training to learn local contexts. AI progress is bottlenecked by backpropagation, which necessitates labelled data to set the ground truth while also leaving a gap between training and inference that result in increasingly larger, more homogenizing models.
We are hiring for applied researchers & various engineering roles– please reach out to ali@aolabs.ai

Dirac is building the next Walmart-sized retail company over 10+ years. We sell d2c and are doing £300k-£500k monthly sales (lots of toys and reasonably seasonal). I built most the initial systems which run the company’s backend (purchasing, databases, pipelines etc.) but we will need something (and someone!) better to reach £1bn+ sales over the next four years
We need to go from a bunch of bash scripts coordinated by systemd, adhoc estimators and pipelines to a more coherent machine for demand estimation, matching products, warehousing and purchasing.
You’ll be mostly writing code (django+postgre+a hetzner server) but also helping our two more junior devs.
The vision for the company is twofold: (1) find 1000s of suppliers and wholesalers worldwide and (2) to ingest all their pricing, logistics and then move stock to where prices and demand is highest.
Visa sponsorship possible.
Investors include will thorndike, charlie songhurst, patio11, backedvc and some others!

Buildings account for ~40% of all emissions. There is a ton of federal, state, and local programs to help decarbonize buildings -- but this money is difficult to access, trapped behind complicated program requirements, uncertain eligibility, lack of clarity, and long payout cycles. We make access to these incentives easy by abstracting away the policy complexity and letting our users focus on their projects. Our platform serves contractors, homeowners, incentive providers and implementers, and equipment manufacturers.
We're hiring Backend Engineers for full time roles.
We're well-funded, have a lot of customer traction, and are rapidly expanding the team. Our product vision is very clear -- the bottleneck is skillful, user-focused execution.
Tech stack: Python (FastAPI, pyright), Google Cloud (GKE), React (Typescript, react-query, auto-gen API client)
We value curiosity, ownership and collaboration. Interest in energy, climate, and sustainability is a plus.
