Artemis Search is a vector database search with a twist. We use special-purpose deep-learning models instead of using textual / semantic similarity to evaluate how good a search result is. This enables us to actually reason how well search results match the intent of the search query, eliminating the problems that come from evaluating search results on how much they look like the search query.

Restaurants send orders to food distributors by email, text, and photo. Someone at the distributor retypes every one of them into the ERP. Asakana does that entry instead: orders land in the ERP already entered, and anything unclear goes to a person before it goes in. Live at US seafood distributors today, returning 40%+ of order-desk time to selling. Founded by a seafood distributor and a Gemini builder.
**Problem** Humans used to need laptops to do their work. Now they prompt agents instead, and those agents need computers too: always-on, in large quantities, and with unlimited capabilities. Building and maintaining that yourself is far from trivial. **Solution** Box provides powerful, simple, permissive Ubuntu VMs in the cloud. In a box, an agent can work for long periods on code or on knowledge work like legal, research, reporting, and auditing. **Why Box and not any other cloud VM?** 1. It is ready out of the box: every box ships with a desktop, chrome, languages, docker, snapshots, and templates, plus a CLI, SDK, API, and control pane for your fleet. 2. It is permissive and paradigm agnostic: any number of agents can use any number of boxes. Agents can run inside or use boxes as an external tool. 3. It is expertly crafted: we manage everything from the individual CPU to the orchestration software, which makes boxes stable, persistent, scalable, and secure. 4. It is the best performance and price in town: our CPUs rank first on HPC benchmarks, and boxes are typically 9x to 18x cheaper than other leading sandboxes. **Further notes** Boxes are hosted in Europe, which keeps prices low, and more regions are coming. Unless compliance requires it, agents don't notice the region they run in.

𝐖𝐡𝐲 𝐰𝐞 𝐛𝐮𝐢𝐥𝐭 𝐭𝐡𝐢𝐬: I (Angel) have had three knee surgeries since my mid-teens and was billed more than $250K for care that should have cost a fraction of that. Fighting those inflated charges was so painful that we set out to build a consumer-facing AI agent to do it for others. In less than five months, we helped sixty patients erase or reduce over $300K from their medical bills. This inspired us to fix the problem farther upstream: stopping bad payments before the patient ever sees a bill. So we launched payment integrity, machine-learning models that audit every medical claim for self-insured employers and health plans in real time. 𝐓𝐡𝐞 𝐏𝐫𝐨𝐛𝐥𝐞𝐦: • Self-insured employers waste $60 B+ each year on claims that never should have been paid. Healthcare is the 2nd largest company expense after payroll. • Manual audits are slow and partial: Reviewers focus only on high-dollar claims, letting millions more slip through unnoticed. • Existing audit software is static: Decades-old rule engines can’t keep pace with evolving codes, contracts, or billing tactics. • Incentives are misaligned: Third-party administrators are paid to process claims, not to police them, so accuracy checks are minimal. 𝐎𝐮𝐫 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧: Our models audit medical claims before and after payments have been issued. We catch nuanced billing, coding, and contract errors to save 3-7% on annual claims spend. We work with self-insured employers and health plans. 𝐀𝐛𝐨𝐮𝐭 𝐔𝐬: Angel Onuoha (CEO) and Ahmad Shehu (CTO) have worked together for 4 years. Before Avelis Health they built Zuvy, a Lagos-based fintech company that provided invoice factoring to small businesses. Zuvy was acquired by The BAS Group in 2025.
