ColdDeckOS: Investor Intro Email Warm-Path Mapper for Pre-Seed Founders

The Problem

Pre-seed and seed-stage indie founders on r/startups and r/indiehackers consistently report that cold investor outreach has near-zero response rates, but they don't know which of their existing network connections are one or two hops from a target investor. ColdDeckOS lets a founder paste a list of target investors, then cross-references their LinkedIn connections, Twitter/X follows, and portfolio company founders to surface the shortest warm intro path for each — ranked by relationship strength signals. It replaces the spreadsheet-and-guesswork process that founders currently do manually before every fundraise.

Target Audience

Pre-seed and seed-stage founders raising their first $250K–$2M who lack VC network access

Monetization Angle

$29/mo during active fundraise; one-time $79 'fundraise sprint' access for a 90-day window

Recommended Tech Stack

Why Now

The 2024–2025 funding environment has forced more founders to bootstrap longer and then raise strategically — warm intros have become the only reliable path as cold email open rates collapse.

MVP Scope

Manual CSV upload of a founder's LinkedIn connections plus a list of 20 target investors, with a simple graph showing which connections have publicly listed the investor as a former colleague, advisor, or portfolio founder.

AI Angle

AI scores each potential intro path by analyzing the public relationship signals between the connector and the investor (shared companies, mutual follows, co-investments) to rank intro quality, not just proximity.

Primary Risk

LinkedIn's aggressive API restrictions and scraping blocks make reliable connection data hard to obtain — the data layer is the core technical risk.

Validation Checklist

• Post 'How do you currently map warm intro paths to investors?' in r/startups and r/indiehackers — manual spreadsheet answers confirm the gap
• Interview 10 founders who raised in the last 12 months about their intro-mapping process and measure time spent
• Build a free static 'Investor Warm Path Calculator' landing page explaining the concept and measure email signups before building the graph engine
• Check if existing tools like Visible, Affinity, or Carta have this feature — if not, validate that founders are actively asking for it in their community forums

Who Would Pay For This

Likely buyers are people already trying to solve this problem with manual workarounds. Start with Pre-seed and seed-stage founders raising their first $250K–$2M who lack VC network access and validate urgency before adding secondary features.
