Coldreach

Tailored Intent Signal Engine

Go beyond static firmographics. Coldreach lets you define what "intent" means for your product in plain English, then scans 97 million accounts in real-time across job sites, news, LinkedIn, and more to find only the leads that match. You can customize prompts to look for signals like "hiring 3+ engineers with Next.js experience" or "mentioned a data breach in the last 12 months," ensuring your list is filled with genuinely in-market prospects, not just names.

AI-Powered, Research-Backed Sequencing

Standing out in a crowded inbox is hard. Coldreach's AI SDR personalizes every single email and LinkedIn message based on the specific buying signals it uncovers. It uses your custom instructions and tone of voice to craft relevant outreach that doesn't sound robotic, then automatically handles multi-touch follow-ups. This turns raw signals into conversations at scale, all powered by the deep research done on each lead.

24/7 Automated Campaign Management

From list building to sending, Coldreach runs on auto-pilot. You can build a highly-targeted campaign in minutes, and the AI takes over: continuously monitoring your Ideal Customer Profile (ICP), vetting every lead with real research, and executing personalized outreach 24/7. This delivers a consistent flow of hot leads to your pipeline without manual effort, saving teams up to 40 hours a week on research alone.

Seamless Ecosystem Integrations

Coldreach fits into your existing workflow without adding complexity. It integrates directly with your core sales stack, including CRMs like Salesforce and HubSpot, engagement platforms like Outreach and Salesloft, LinkedIn Sales Navigator, and communication tools like Slack and Gong. This allows for smooth data sync, notifications, and engagement tracking, so you get better leads without changing how you work.

Use Cases

Claude Fast

Rapid MVP Development

Startups can utilize Claude Fast to build their Minimum Viable Product (MVP) in record time. With features like intelligent routing and session management, teams can focus on innovation instead of getting bogged down in technical details, accelerating their journey from concept to launch.

Streamlined Marketing Campaigns

Marketing teams can leverage Claude Fast to design and execute campaigns efficiently. The tool’s task syncing and agent orchestration simplify collaboration, allowing marketers to focus on creative strategies while the system handles the logistics of execution.

Efficient Code Deployment

Enhanced Team Collaboration

With shared session memory and task management sync, teams can collaborate more effectively on complex projects. Claude Fast ensures that everyone is on the same page, reducing miscommunication and improving workflow efficiency across diverse teams.

Coldreach

Targeting Companies in Active Hiring Cycles

Identify and engage companies the moment they signal growth and new needs. Coldreach can monitor for specific job descriptions, like "hiring finance personnel who build expense reports in Excel," indicating a pain point ripe for a spend management or automation solution. This allows SDRs to reach out when the prospect's problem is top of mind, dramatically increasing relevance and reply rates.

Capitalizing on Public News or Events

Never miss a company undergoing change. The AI scans news articles, press releases, and even SEC filings (like 10-K reports) for triggers such as a recent cybersecurity attack, a new funding round, or mentions of major new HR initiatives. Sales teams can use this to offer timely solutions, positioning their product as the direct answer to a publicly acknowledged challenge or new strategic priority.

Engaging Based on Technology Adoption

Reach out with perfect context when a company is investing in new tech. Coldreach can find signals like a company onboarding a Data Engineer who mentions Snowflake on their LinkedIn or a website update showing new SOC 2 Type 2 compliance. This enables technical sales teams to personalize outreach around integration, security, or scalability with unmatched precision.

Running Niche, Hyper-Targeted Outbound Campaigns

Quickly launch campaigns for specific verticals or scenarios without manual list-building. For example, target all insurance service providers attending cloud conferences, or companies that recently posted engineering jobs requiring a specific framework. Coldreach builds, vets, and engages these targeted lists automatically, making it possible to test new markets or personas with speed and intelligence.
