Call centres represent a $29 billion market, with global enterprises continuing to view telesales as a vital component of their business strategy. Voice communication adds a personal touch to sales, builds consumer trust, and enables complex interactions to progress swiftly in real-time. With a mere 1% detection rate and the capacity to handle 100 simultaneous phone lines during peak hours, Solda.AI has pioneered a breakthrough in sales automation by developing AI voice agents capable of closing sales over the phone.
The innovative AI voice agent startup has announced €4M in seed funding, led by Accel, with participation from AltaIR Capital. The funding will support their mission to revolutionise phone sales through easily deployable multimodal AI voice agents that can close deals independently.
Solda.AI will use this seed funding to accelerate the development of its AI voice agents, which generated €7M in incremental revenue for clients in 2024 and are projected to reach €30M this year. Their current client roster includes tbi bank, Treatwell, InDrive, Plata Bank, and Vivid Money.
How Solda.AI transforms telesales with AI voice agents
While conversational AI has revolutionized customer service in recent years by automating and enhancing customer interactions, sales automation has remained challenging. Until recently, replicating natural human conversation flow seemed impossible. Research shows people trust human voices twice as much as AI voices, and artificial voice technology has traditionally struggled with complex sales conversations. AI voices were typically detected within minutes, undermining deals and hindering AI-enabled efficiency.
Today, breakthroughs in large language models (LLMs) and emotion-aware voice synthesis have changed this landscape. Solda.AI’s agents achieve a remarkable 1% detection rate, enabling seamless integration into existing sales workflows and sophisticated conversation handling. While fewer than 10% of human call center agents become proficient within two months, Solda.AI’s voice agents are ready for lead engagement after just two weeks of training. They can process 10,000 leads daily—including follow-ups and callbacks—in six languages, with proficiency in regional dialects like Mexican Spanish and Brazilian Portuguese.
Companies using Solda.AI report 30% lower telesales costs compared to traditional centers, thanks to reduced overhead and improved conversion rates. In 2024, clients generated €7 million in incremental revenue, with projections reaching €30 million in 2025.
Real-world results and industry validation
Founded in 2023 by Sergey Shalaev, an AI and ML entrepreneur with 12+ years of experience in recommendation services, advertising technologies, and MedTech, Solda.AI operates as a remote-first company. The team spans Amsterdam, Berlin, London, and Munich, combining technical and sales expertise with cutting-edge LLM advancements to achieve remarkable early success.

Zhenya Loginov, partner at Accel, said: “When we first met Sergey and the Solda.AI team, we were blown away by the AI voice agents’ human-like qualities and ability to not only handle complex conversations but also close deals immediately. Solda.AI’s technology has the potential to revolutionize the telesales market, with the team using AI to redefine sales automation from the ground up. They’re already delivering on their goal to boost sales revenue with AI, achieving impressively low detection rates with a scalable product design. We’re excited to partner with the team and witness their future achievements.”
Pavels Gilodo, Consumer Ecosystem Lead at tbi bank, said: “At tbi bank, innovation drives everything we do. Partnering with Solda.AI has transformed our customer communication strategy. Victoria AI, our AI-driven outbound sales agent, allows us to engage customers at scale while maintaining a personal touch. The results speak for themselves—improved operational efficiency, enhanced customer satisfaction, and significant contributions to our business goals. This collaboration demonstrates how technology and shared vision can redefine customer engagement in banking.”
As Solda.AI’s voice agents evolve, future versions will incorporate predictive analytics, using historical call data to anticipate customer needs and optimize pitch timing. CRM system integration will enable real-time lead scoring, helping agents focus on high-intent prospects. With regulatory and ethical considerations on the horizon, Solda.AI is well-positioned to help enterprises navigate an evolving sales landscape.
As the AI voice market gains momentum, Solda.AI’s focus on ROI-driven automation establishes it as a cornerstone of next-generation sales technology. For enterprises, the path forward is clear: embrace AI-driven sales or risk falling behind in an increasingly automated world.
