Large-Scale AI Outreach: Hundreds of Sales Meetings Booked Monthly
Built a custom LLM-powered outreach platform for a stealth marketing startup, automating prospect discovery, personalized messaging, and conversation management at scale using fine-tuned models and RAG.

The Client
The stealth marketing startup was building a next-generation outreach platform to solve a fundamental sales problem: personalized prospecting doesn’t scale, and scaled prospecting isn’t personalized. Traditional outreach tools forced a choice—either send generic mass emails (high volume, low conversion) or have sales reps manually research each prospect and write custom messages (high conversion, impossible volume).
The founding team had deep sales operations experience and understood that the emerging LLM ecosystem could finally bridge this gap. They needed a technical partner to architect, build, and deploy an MVP that would demonstrate AI-powered outreach could match human-quality personalization at machine-level scale.
The Challenge
The technical challenge spanned three distinct systems that needed to work in concert. First, prospect discovery: automatically finding and qualifying hundreds of potential customers daily from professional networks including LinkedIn, then enriching each profile with additional web research to build comprehensive prospect profiles. Second, personalized messaging: generating outreach messages that felt individually crafted—referencing the prospect’s specific role, recent company news, shared connections, or industry challenges—while incorporating the client’s unique value proposition and knowledge base. Third, conversation management: maintaining coherent, personalized dialogue across thousands of simultaneous prospect conversations over both short and long-term campaign cycles.
Each system had distinct AI challenges. Discovery required intelligent web scraping with multi-page summarization to extract relevant prospect information from unstructured web content. Messaging required understanding both the prospect’s context and the client’s offering deeply enough to write compelling, non-generic copy. Conversation management required maintaining context across multiple exchanges while adapting tone and content based on prospect responses.
Our Solution
We built the platform as an AI Agent framework with three integrated components. For prospect discovery, we developed automated web scraping agents that searched professional platforms, extracted profile information, and conducted follow-up web research to enrich each prospect’s profile. A custom AI agent handled multi-page summarization—distilling lengthy company websites, blog posts, and news articles into concise prospect intelligence briefs.
For personalized messaging, we fine-tuned custom language models on the client’s voice, value propositions, and successful outreach patterns. The models generated messages that incorporated prospect-specific details from the discovery phase with the client’s internal knowledge base, accessed through advanced RAG techniques. Vector embeddings of the client’s knowledge base—case studies, product documentation, industry insights—enabled the system to pull relevant talking points for each unique prospect.
For conversation management, the system tracked dialogue state across thousands of concurrent conversations, adapting responses based on prospect engagement signals and maintaining coherent multi-turn interactions. The fine-tuned models ensured responses stayed on-brand and strategically aligned throughout extended conversation sequences.
The Impact
The platform achieved production-scale operation: finding and qualifying hundreds of prospects per day per client, managing thousands of personalized prospect conversations daily, and booking hundreds of qualified sales meetings per month. The outreach quality was indistinguishable from hand-crafted messages—prospects engaged in genuine conversations rather than recognizing automated outreach.
The AI Agent architecture proved its value in adaptability. When clients entered new verticals or adjusted their ideal customer profile, the system adapted through knowledge base updates and prompt refinement rather than requiring re-engineering. The MVP validated the startup’s core thesis—AI-powered personalization at scale—providing the traction needed to advance their fundraising and product roadmap.
