CallPrep โ€” AI prospect research and outreach, delivered where you already work

CallPrep is an AI-powered prospect research and enrichment platform for sales teams and platform builders. Instead of returning raw data fields, CallPrep does the research a good BDR would do before a call โ€” and delivers the result as a ready-to-use battlecard wherever your team works.

How it works

Send CallPrep a prospect's email address or LinkedIn URL. It researches the person and their company โ€” role and background, company overview, pain points, decision-makers, recent activity, and suggested talking points โ€” and returns a structured battlecard you can drop straight into your workflow.

Where the data lands

  • HubSpot โ€” enrich contacts and companies natively via OAuth, with automated reply threading
  • Email (Gmail) โ€” battlecards delivered to your inbox before the call
  • Claude (MCP) โ€” use CallPrep as a native tool inside Claude
  • REST API โ€” bring enriched research into your own app or product
  • n8n / Zapier / Make โ€” add CallPrep's API as a step and it runs automatically

Autopilot: from research to outreach

CallPrep also runs as an AI BDR Autopilot: when a new lead arrives, it researches them and reaches out with a personalized message via LinkedIn, email, or WhatsApp within about 5 minutes โ€” from your rep's own account.

Who it's for

  • Sales reps who want to walk into every call prepared
  • Founders doing founder-led sales who need research and follow-up handled automatically
  • Developers and platform builders adding enrichment or an AI BDR layer to their product

ChartGen features and specs

  • AI-Powered Automation
    ChartGen uses artificial intelligence to automatically generate charts and visualizations from raw data, significantly reducing the manual effort and time required to create data visualizations.
  • User-Friendly Interface
    The platform is designed to be accessible to users without extensive technical or design skills, allowing quick creation of professional-looking charts.
  • Speed of Chart Creation
    By automating the visualization process, ChartGen enables users to generate charts much faster than traditional manual methods using tools like Excel or design software.
  • Variety of Chart Types
    The tool typically supports multiple chart formats and styles, giving users flexibility to choose the best visualization for their specific data storytelling needs.
  • Accessibility for Non-Designers
    Users without a background in data visualization or graphic design can still produce polished, presentation-ready charts using AI assistance.

Possible disadvantages of ChartGen

  • Limited Customization
    AI-generated charts may offer less granular control over design details compared to dedicated design tools like Adobe Illustrator or advanced charting libraries such as D3.js.
  • Dependency on AI Interpretation
    Since the AI interprets data and chooses visualization styles, there is a risk it may not always align perfectly with the user's specific intent or industry-standard conventions.
  • Newer Platform Uncertainty
    As a relatively newer tool in the market, ChartGen may have a smaller user community, fewer third-party integrations, and less extensive documentation compared to established visualization tools.
  • Potential Data Privacy Concerns
    Uploading sensitive or proprietary data to an AI-based cloud platform may raise concerns about data security and privacy, especially for enterprise users handling confidential information.
  • Learning Curve for Advanced Features
    While basic chart generation may be simple, fully leveraging AI-specific features or advanced customization options might require some learning and experimentation.

Questions & Answers

As answered by people managing ChartGen and CallPrep.app.

Who are some of the biggest customers of your product?

CallPrep.app's answer:

Juicer, ToHuman, and others

Which are the primary technologies used for building your product?

CallPrep.app's answer:

CallPrep is built with React and TypeScript (Next.js), with Supabase (PostgreSQL) as the data layer. The AI research engine runs on Anthropic's Claude models. The product surfaces are a REST API, a Chrome extension, and a web app, with native OAuth integrations for HubSpot and Gmail and an MCP server for Claude. Transactional email runs on Resend, and the platform is deployed on Cloudflare.

What makes your product unique?

CallPrep.app's answer:

Most sales tools give you raw data fields; CallPrep does the actual research. Its research engine reads the prospect's company, role, and recent activity, then turns it into a battlecard a rep can use in the next five minutes โ€” and the same brain powers the outreach, so every LinkedIn, email, or WhatsApp message is grounded in real research, not a template. Messages go out from your rep's own account, not a spoofed domain. And it delivers where you already work: HubSpot, Claude (MCP), or your own app via API โ€” no new dashboard to live in.

Why should a person choose your product over its competitors?

CallPrep.app's answer:

Data providers like ZoomInfo, Clearbit, or Apollo sell you contact records โ€” you still have to research each lead and write the outreach yourself. Enrichment workflow tools like Clay are powerful but require building and maintaining pipelines. CallPrep closes the whole loop: it researches the person and company, builds a usable battlecard, and sends personalized outreach from your rep's own account within about 5 minutes of a lead arriving. There's no pipeline to build and no seat-heavy enterprise contract โ€” it starts free, and a solo founder or a small sales team can be running the same day.

How would you describe the primary audience of your product?

CallPrep.app's answer:

CallPrep serves two audiences. First, small B2B sales teams, founders doing founder-led sales, and individual reps who get inbound leads but don't have a BDR to research and follow up on them fast. Second, developers and platform builders who want to add prospect research, enrichment, or an AI BDR layer to their own product via the REST API or Claude (MCP) integration โ€” without building a research pipeline themselves.

What's the story behind your product?

CallPrep.app's answer:

CallPrep started with a painful budget decision. I had to cut BDRs from my team, and the plan to hire five never happened. But the leads kept coming, and every one of them still needed what a BDR does: research the company, find the pain points, write a personal message, follow up fast. So I started automating the work itself โ€” an engine that researches every new lead, builds a battlecard, and reaches out on LinkedIn, email, or WhatsApp within five minutes, from the rep's own account. Today we run with one BDR plus CallPrep doing the work of the rest of the team. Then I turned it into a product, because most small sales teams face the same math we did.
