Antek Automation is a UK based agency dedicated to helping tech service businesses scale without adding headcount. We specialise in building Voice AI agents powered by Retell that handle inbound calls 24/7, qualify leads instantly, and book appointments while teams stay focused on delivery. Our focus is on serving busy tech service companies—SaaS providers, software agencies, IT consultancies, and digital service businesses—who need to capture every opportunity without the overhead of expanding their customer-facing teams. We combine deep technical expertise with a genuine understanding of how service businesses operate, creating solutions that integrate seamlessly into existing workflows via n8n automation. We’re committed to making Voice AI accessible and genuinely useful for growing tech companies who’ve been underserved by generic automation tools that promise everything but deliver complexity. Based in Hampshire, we serve clients across the UK who value practical automation that delivers measurable ROI.

SixFlow Automations is an AI automation agency specializing in production-grade voice AI solutions powered by Retell AI. We design, deploy, and manage intelligent voice agents that handle real customer interactions—from inbound sales and lead qualification to appointment scheduling and customer support. What sets us apart is our full-stack approach to voice AI implementation. Beyond building natural-sounding, brand-aligned agents, we’ve developed a real-time analytics platform that’s built directly on data streamed from Retell AI. This system gives clients full transparency into their AI operations with access to call recordings, performance metrics, conversation analysis, billing usage, and reliability statistics. By visualizing Retell’s data in a clear and actionable way, our platform helps businesses monitor every aspect of their system, build trust, and confidently scale their AI infrastructure. We’ve also integrated a live voice agent directly on our website, allowing visitors to speak with an AI-powered representative and learn about SixFlow’s services in real time. This interactive demo showcases the technology we build for clients and demonstrates the power of conversational AI as a 24/7 engagement tool. In addition, we run a growing community of automation builders and business owners where we teach others how to design, deploy, and scale their own Retell AI agents. Every SixFlow implementation includes seamless integration with CRMs, calendars, and databases, along with custom knowledge base development and ongoing optimization. We don’t just deliver AI agents—we build the entire automation infrastructure that helps businesses grow intelligently, transparently, and at scale.
