Solda.AI, a fast-growing startup transforming phone sales with AI voice agents, has raised $4 million in seed funding. The round was led by Accel, with participation from AltaIR Capital. The investment will boost the company’s mission to make AI voice agents the new standard in telesales.
This funding comes as Solda.AI’s agents prove their value. In 2024, clients generated €7 million in new revenue through the platform. That figure is expected to climb to €30 million by the end of 2025. Solda.AI’s client base already includes well-known brands like tbi bank, Treatwell, InDrive, Plata Bank, and Vivid Money.
Transforming Phone Sales with Multilingual AI Voice Agents
Despite advances in conversational AI, telesales has remained hard to automate. Many voice bots sound robotic, struggle with context, and are quickly detected. Research shows humans trust natural voices twice as much as artificial ones. This distrust has made it difficult for companies to use AI in high-stakes sales calls.
Solda.AI is changing this. Its AI voice agents have a detection rate of just 1%, even while handling up to 100 concurrent calls. These agents can conduct complex sales conversations in six languages, including local dialects like Brazilian Portuguese and Mexican Spanish. After only two weeks of training, they’re ready to engage with leads, unlike human agents who often need months.
What makes them different is their use of large language models (LLMs) and emotion-aware speech synthesis. They adapt tone, timing, and pitch to match human conversation, allowing them to sound natural and persuasive. Solda.AI’s agents are also multimodal, meaning they can respond across voice and text channels and connect with CRM systems for real-time lead scoring.
These features save clients money while improving performance. On average, companies using Solda.AI report a 30% reduction in telesales costs. They also see better conversion rates due to faster lead engagement and follow-ups.
Founder-Led Innovation and Real-World Results
Founded in 2023 by Sergey Shalaev, an AI and machine learning expert, Solda.AI operates remotely across Amsterdam, Berlin, London, and Munich. Shalaev brings over 12 years of experience from recommendation systems, MedTech, and ad technologies.
Under his leadership, Solda.AI has already deployed its AI voice agents with 20 enterprise partners. The agents don’t just handle calls—they close sales and provide measurable ROI. Shalaev believes this is the future of telesales.
“When we started Solda.AI, we set out to prove that AI could sell, not just support,” he said. “This seed round lets us scale our voice agents and bring AI-powered phone sales to more businesses around the world.”
Investors share his vision. Zhenya Loginov from Accel said, “The agents sound human and handle complex conversations seamlessly. Solda.AI has built a scalable solution that can change how companies approach sales.”
That view is echoed by clients. Pavels Gilodo of tbi bank shared: “Victoria AI, our outbound sales agent powered by Solda.AI, helps us reach more customers while keeping a personal touch. It’s improved efficiency and helped us meet business goals.”
Looking ahead, Solda.AI plans to add predictive analytics to its platform. By using historical call data, the system will predict customer needs and suggest the best pitch timing. Real-time integrations with CRM tools will help prioritize high-potential leads.
As more companies look for ways to automate sales, Solda.AI is leading the way. Its AI voice agents offer a clear advantage: speed, scale, and results. For enterprises that want to stay competitive, adopting this tech is no longer optional—it’s essential.
