How KnokAI Helped Scale Sales With AI Personalization

Sales teams can’t scale with copy-paste campaigns. That’s why a leading B2B consultancy partnered with Festi to build KnokAI, a custom AI agent designed to automate outbound sales while keeping every message personal and relevant. Since launching the KnokAI agent, the client achieved:

• 85% reduction in manual outreach time
• 3× increase in reply rates
• 2-month implementation timeline
• 10+ hours saved per rep each week
• 20% pipeline growth in under 90 days

Project highlights

• Developed a fully automated outbound platform powered by large language models
• Implemented real-time personalization based on lead context and company data
• Integrated with email, and Google Workspace for seamless execution
• Sped up campaign deployment with dynamic channel selection
• Increased outbound volume and lead conversion without expanding the team

The challenge

Our client, a fast-scaling B2B consultancy, needed a smarter way to personalize sales outreach. Their sales team was juggling lead research, message crafting, and multi-platform engagement, which led to burnout and inconsistent results.

Despite having a capable team, the volume of leads was too high to maintain personalization at scale. Sales reps were spending hours each day drafting messages and guessing which channel to use. As a result, valuable leads went cold and pipeline growth stalled.

The company needed a system that could deliver the same level of personalization, but at scale, and without adding headcount.

Client request

The client wanted to build a platform that could scale outbound sales efficiently while keeping messages highly contextual. Their goals were clear:

• Generate unique, tailored messages for each lead
• Choose the right outreach channel automatically
• Connect easily with Google Workspace, LinkedIn, and internal systems
• Offer on-premise and cloud deployment options for flexibility
• Make it simple enough for sales reps to use without technical support

The solution

We partnered with the client to design and build KnokAI, an AI-powered outbound automation platform that streamlines outreach from start to send. At the core of the solution is a flexible AI engine powered by Azure OpenAI, Semantic Kernel, and Ollama. It generates personalized messages using lead context pulled from sources like LinkedIn, CRM data, and company websites.

Built for sales, powered by Festi

Using Festi’s modular backend and automation tools, we integrated multiple components to ensure seamless delivery:

• C# and .NET Blazor for the platform front end
• Postgres for structured data storage
• ChromaDB for lead embeddings and context management
• Google Workspace API for syncing calendars, sending emails, and managing campaigns
• Role-based access and secure deployment, including on-premise support

We worked closely with the client’s team to identify key workflows, optimize performance, and document every step. Festi’s developer-friendly foundation made it easy to adapt quickly and stay on schedule.

Overcoming key challenges

Hallucinated content, rate limits, and campaign delays were addressed through:

• Prompt fine-tuning based on historical sales messages
• Retry and queuing logic for third-party API stability
• Real-time visibility into campaign performance with admin dashboards

By focusing on simplicity for the end user and sophistication under the hood, KnokAI delivered fast results without adding operational burden.

The result

The KnokAI agent quickly became essential to the client’s sales workflow. The platform enabled them to reach more leads, faster, with better engagement, and with no need for additional hires or external tools.

• 85% less time spent on manual prospecting
• 3× higher reply rates
• 2-month timeline from kickoff to deployment
• 10+ hours saved per week for each sales rep
• 20% pipeline growth within three months
