The former McKinsey and former YC leader launches RationalGO, an India-based agent AI platform that enables autonomous agents to perform real-world tasks end-to-end.
At a defining moment for the Indian AI ecosystem, a new Agentic AI platform, RationalGO, is emerging as a strong contender on the global stage. Founded by former McKinsey technology leader Praveen Yadav and former YC-backed startup operator Kumar Ajay, the company is focused on a clear mission: moving AI from intelligence to execution.
While large-scale language models (LLMs) have transformed the way humans and machines interact, the founders believe the next leap forward will come from the application layer: systems that can plan, reason, and autonomously complete real-world work. “Models are powerful, but the impact comes when AI can actually perform end-to-end tasks for people at scale,” says Praveen Yadav.
Praveen left McKinsey two years ago to pursue this vision after advising companies on technology and transformation. Around the same time, Kumar Ajay was building voice AI infrastructure for India and working across product and growth at scale. Their collaboration began with a shared recognition that despite rapid advances in AI, most products still fall short of real-world execution.
Proven execution across voice and agent AI
Prior to making RationalGO publicly available, the duo shipped Bolcho.ai, an enterprise voice AI infrastructure platform designed to solve one of the industry’s biggest bottlenecks: cost. Bolcho.ai helps enterprises reduce voice AI operational costs by up to 80% by redesigning inference pipelines, agent orchestration, and infrastructure efficiency.
Bolcho.ai has already been adopted in large-scale voice deployments in India and serves as a foundational learning ground for building efficient, low-latency, agent-driven systems. These learnings directly influenced the architecture behind RationalGO’s Agentic AI platform.

RationalGO: Competing with global agent AI platforms
Released in early 2025, RationalGO.ai allows users to delegate complex tasks such as building websites, creating presentations, generating simulations, and writing reports to autonomous AI agents that plan, execute, and deliver results with minimal human intervention.
In early benchmarks, RationalGO competes with global Agentic AI platforms including Genspark (Southeast Asia), Kimi AI, Manus (acquired by Meta), and Claude’s Agentic AI products. RationalGO has demonstrated superior performance in key metrics such as time to results, computational efficiency, and LLM cost optimization, despite operating with significantly less capital.
Build quietly, build deeply
Since December 2024, the founders have chosen engineering depth over hype and built RationalGO with limited external funding. “In the AI era, the real MOAT is speed,” says Praveen Yadav. “Speed of learning, speed of iteration, speed of execution.”
This philosophy has driven a rapid transformation from a desktop-first approach to a scalable cloud platform while maintaining a relentless focus on performance, cost efficiency, and reliability. Both founders draw on their previous startup experience and believe that long-term impact is built through patience rather than rapid capital deployment.
India’s agentic AI moment
As Agentic AI becomes the next frontier in artificial intelligence, RationalGO and Bolcho.ai represent a broader shift in India’s role from AI adoption to AI infrastructure and systems leadership. The founders believe that the Indian team has the ability to compete with the world’s largest technology ecosystem.
The future, they argue, belongs to AI that works quietly in the background, coordinating agents, performing tasks, and allowing humans to focus on higher-order thinking.
