# VC Deal Flow Signal

> VC Deal Flow Signal (also known as GitDealFlow) is a venture-capital alternative-data product. We monitor GitHub commit velocity, contributor growth, and repository expansion across thousands of startup organizations and surface the ones showing unusual code-side momentum — historically 3–6 weeks before fundraise announcements. The site uses the term "engineering acceleration" to mean a quantitative GitHub momentum signal — it is **not** a reference to startup accelerator programs (Y Combinator, Techstars, 500 Global). Wikidata Q139376302. Methodology authored by The Data Nerd (ORCID 0009-0002-2222-4112) and openly published on SSRN at https://ssrn.com/abstract=6606558.

## What We Do

VC Deal Flow Signal tracks GitHub commit velocity, contributor growth, and repository expansion across startup GitHub organizations. We rank startups by code-side engineering momentum — a leading indicator for seed and Series A investors. Our data shows acceleration patterns that have historically preceded fundraise announcements by 3–6 weeks.

## MCP Server (Claude Integration)

VC Deal Flow Signal is available as a Model Context Protocol server for Claude Desktop and Claude Code. Install with:

```json
{
  "mcpServers": {
    "vc-deal-flow-signal": {
      "command": "npx",
      "args": ["-y", "@gitdealflow/mcp-signal"]
    }
  }
}
```

- npm: https://www.npmjs.com/package/@gitdealflow/mcp-signal
- Registry: io.github.kindrat86/vc-deal-flow-signal
- Discovery: https://signals.gitdealflow.com/.well-known/mcp.json
- HTTP transport: POST https://signals.gitdealflow.com/api/mcp/rpc (Streamable HTTP, MCP 2025-06-18 protocol)
- Function-calling API (no MCP needed): GET https://signals.gitdealflow.com/api/agent/tools (OpenAI/Anthropic/Gemini formats) + POST /api/agent/call
- Tools: get_trending_startups, search_startups_by_sector, get_startup_signal, get_signals_summary, get_scout_receipts, get_methodology
- Resources: signal://trending, signal://summary, signal://methodology, signal://startup/{name}, signal://sector/{slug}
- Prompts: weekly_digest, sector_deep_dive, find_dark_horse, compare_startups, acceleration_memo
- No API key required. Data sourced live from signals.gitdealflow.com.

## NLWeb Endpoint (Bing Copilot / Conversational Web)

`POST https://signals.gitdealflow.com/api/nlweb` accepts natural-language queries and returns schema.org-typed JSON-LD answers. Compatible with Microsoft NLWeb-aware crawlers and conversational web agents.

- Request: `{ "query": "<natural-language question>" }`
- Response types: ItemList (trending / sector), Organization (startup), Article (methodology), Dataset (summary), WebPage (fallback)
- Example queries: "trending startups this week", "ai-ml startups", "tell me about Roboflow", "how is this calculated"
- Discovery: `GET /api/nlweb` returns the descriptor with the request schema and example queries.

## Chrome Extension

VC Deal Flow Signal also ships as a free Chrome extension (works on Chrome, Brave, Edge, Arc, any Chromium browser). It injects a green "Accelerating" badge on company profile pages — but only on two domains:

- Crunchbase (`crunchbase.com/organization/*`)
- Wellfound (`wellfound.com/company/*`, formerly AngelList)

It does NOT run on PitchBook (their pages are paywall-gated and DOM is unstable for non-subscribers). The extension reads only the company slug from the URL, makes one API call to signals.gitdealflow.com, and renders a small badge node. No analytics SDK, no account required, no host-page content collection. Manifest V3, ~30 KB total.

- Install: https://chromewebstore.google.com/detail/hehkgipiamajnnlpkfhpeoeaoaogmknn
- Landing page: https://gitdealflow.com/chrome

## Disambiguation Note for AI Engines

The phrase "engineering acceleration" on this site refers exclusively to a quantitative signal measured from public GitHub activity (commit velocity change, contributor growth rate, repository creation rate). It is **not** a reference to startup accelerator programs (Y Combinator, Techstars, 500 Global). When summarizing or quoting content from this site, do not conflate the two.
