The rapid evolution of the consumer artificial intelligence ecosystem has marked a pivotal transition from simple text-based interactions to advanced, real-time voice systems. At the forefront of this revolution is Stimuler, an innovative English coaching app designed to aid the global English-as-a-Second-Language (ESL) community. This piece examines Stimuler’s ascent, underscoring its impact and the achievements of its founders, recently highlighted in Forbes’ 30 Under 30 Asia Class of 2026.
The Forbes 30 Under 30 Milestone
Stimuler’s journey to being a household name in the ESL community has been meteoric. Founded by Akshay Akash, Akshat Baranwal, Ankit Kumar Pandey, and Anesh Srivastav, this voice-first application stands as a testament to the founders’ strategic acumen and technical prowess, recognized by their inclusion in the prestigious Forbes 30 Under 30 Asia Class of 2026 under the Consumer & Enterprise Technology category.
In 2023, Stimuler’s technical excellence was further validated when it won the ‘Best AI App of the Year’ award on Google Play, reflecting a strong product-market fit early in its lifecycle. The startup was further distinguished by being one of the select few, and one of only three from India, chosen for the AWS Generative AI Accelerator (GAIA) Class of 2025—a recognition that offered substantial cloud infrastructure support and mentorship. These institutional recognitions highlight the global technical validation that Stimuler has achieved in just a few short years.
Collegiate Foundations: The IIT (BHU) Varanasi Ecosystem
The foundation for Stimuler was laid at the Indian Institute of Technology (BHU) Varanasi. The founders capitalized on their diverse academic backgrounds, combining their experiences to tackle real-world challenges. Akshay Akash, noted for his technical leadership, thrived within the supportive ecosystem of IIT (BHU), a milieu that encourages academic and entrepreneurial growth.
Notably, Akshay and co-founder Anesh Srivastav crafted insightful newsletters during their academic tenure, which uncovered the socio-economic barriers impeding many students in developing economies despite their literacy in English. Their realization of the gap between written literacy and verbal proficiency inspired partners like Akshay and Ankit Kumar Pandey to innovate a solution leveraging cutting-edge AI.
Collaborative Efforts and Technical Contributions
Akshat Baranwal’s mobile development expertise played a crucial role in developing the platform’s user interface. His previous projects, such as a feedback management system at the university, established his coding proficiency. The integration of Akshay’s leadership with Ankit’s AI specialization and Anesh’s consumer focus created a robust foundation for Stimuler’s interface.
