Self-hosted AI deal discovery for solo operators: angels, scouts, and sector-focused VCs. It reads public signals, extracts company and founder data with Claude, and scores everything against a Markdown thesis you write and version yourself. Thesis-as-code, transparent scoring, no data-provider lock-in.
Deal sourcing for a solo investor is mostly reading. Neural Seed does the first pass: it watches public signals, turns unstructured posts into structured company records, and ranks them against the thesis you actually invest on.
GitHub trending, Hacker News “Show HN”, and any RSS feeds you configure. An in-process scheduler runs GitHub trending daily and Show HN hourly.
Claude pulls company and founder records out of the raw posts using tool-use at temperature=0, and the prompt hashes are stored alongside the result.
Each company is scored against a Markdown thesis you control. It ships with theses/devinfra-v1.md as a worked example; fork it and write your own rubric.
A server-rendered web UI shows the ranked pipeline, plus a daily brief printed to stdout: the top three companies scoring 7.0 or above in the last 24 hours.
The interesting design decision is that the thesis is a file, not a setting buried in a UI. That makes the scoring reviewable, diffable, and versioned like any other artifact.
Theses are Markdown with a YAML front-matter block. Copy the bundled one, rewrite the prose and the weights, and point the app at it with an environment variable. The five axes themselves (market, team, traction, fit, timing) are a fixed set in this phase; you control their weights and what they mean, not their names.
Scores are keyed on {name}-{version}-{sha256(body)[:8]}, so editing the body of the thesis mints a new version and leaves earlier scores intact. Scores are append-only, so re-scoring adds a row rather than overwriting one.
A score points back to the exact prompt bytes, the model version, and the source documents that produced it. You can always ask why a company ranked where it did.
Signals come from public sources you can inspect rather than a paid data vendor, and the whole stack runs on your own machine.
Demo mode needs no API keys. It generates a deterministic synthetic dataset of 52 companies, clearly flagged as demo data, so you can walk the pipeline before wiring anything up.
To use your own thesis, copy theses/devinfra-v1.md, edit the rubric, then set NEURAL_SEED_THESIS=my-thesis-v1 and run again.
Run it on localhost only. The project ships with no authentication and its README is explicit about this: do not expose it to the public internet. Treat it as a single-operator tool on your own machine.
The stack is deliberately boring and self-hostable:
Full mode needs an ANTHROPIC_API_KEY, a GITHUB_TOKEN and a VOYAGE_API_KEY, plus Postgres running via Docker Compose. Design notes, the data model, and the LLM contracts are documented in DESIGN.md in the repo.
The repo describes itself as a Phase 1 vertical slice, and its own contributing guide calls it an experimental project. That framing is worth taking at face value: the end-to-end loop is real code with a real schema and offline tests, but it is a reference architecture rather than a finished product.
The ingest → extract → score → UI loop, three connectors, seven Postgres tables, forced tool-use extraction, and the provenance discipline: content hashes for dedup, prompt and thesis hashes stamped on every score row, and append-only scores.
SMTP settings exist but the daily brief only prints to stdout. Langfuse variables exist but nothing reads them. Embeddings are computed and indexed, but nothing queries them yet, so there is no semantic search in this phase.
Authentication, multi-tenancy, multiple simultaneous theses, knowledge graphs, multi-agent diligence, and paid data providers are all named non-goals for this phase, not oversights.
There are no benchmarks, cost measurements, or accuracy evaluations in the repo, and none are implied here. Entity resolution is exact-name matching by design, with fuzzy matching deferred.
