Perseus
Perseus takes an iterative branching approach to search in high dimensional spaces. Our first product helps coding agents find the right codebase context before they write. It searches files, symbols, and dependencies in parallel, so models can make better changes with less trial and error. Perseus Search gives Mythos-level programming ability to Opus-level coding agents.

sourcePerseus is classified as AI agents from source descriptions and fund-directory context. Similar companies below are ranked from offline product facets and meaningful description overlap; category and source affiliation can only strengthen an existing product match. For lookup-created rows, the profile starts as pending enrichment until deeper source collection runs.
Local clusters rerank extracted product concepts and description terms. The generated graph remains the fallback for sparse descriptions: offline reciprocal product-similarity graph: extracted concepts + description terms + bounded category/affiliation boosts. Minimum fallback score: 0; max competitors: 6.

Lotas
match 59For our first product, we built Rao: an AI coding assistant into RStudio — an IDE used by up to 5 million data scientists and statisticians who use the R programming language to analyze data. Rao could read, write, and edit code while understanding the user's context (codebase and environmental variables).

Muddy
match 41Muddy is a chat-like web browser (built on Chromium). Teams use Muddy to work with their teammates and software all in one window. Muddy consists of Spaces: project, event, or competency based feeds in which users can send updates that consist of basic multimedia messages, specific files from applications (Google Doc, Airtable Base, Figma File, +anything web based), and annotations on both. Recipients can then use those apps right in line of the messages to take the requested action or give the

Driver
match 41Driver is the context layer that translates your codebase into shared, structured understanding. By computing context ahead of time, Driver delivers symbol‑complete documentation, architecture maps, and history guides so teams and agents can reason across an entire codebase without guesswork.
