ColdCraft

AI-powered cold email writer that personalizes at scale.

● The Problem

Cold email response rates average 1-3%. Most outbound tools send generic templates. Personalizing each email manually takes 10-15 minutes per prospect, making it impractical at scale.

● The Solution

An email tool that scrapes prospect LinkedIn profiles, company news, and recent posts to generate genuinely personalized openers and value props. Not templates with merge fields. Actually different emails for each person.

Competitive Landscape

Lemlist, Instantly, and Apollo dominate outbound. But their AI personalization is shallow (company name insertion). Deep personalization using LLMs is still a differentiator.

Why Now?

Email providers are penalizing bulk sends. The only way to maintain deliverability is genuine personalization, which LLMs finally make possible at scale.
