Bolna - Voice AI platform built for India

What is Bolna

If you're running a business in India, you know the struggle: customers expect 24/7 support, but hiring round-the-clock staff is expensive. Language barriers make it even harder—your customers speak Hindi, Tamil, Telugu, Hinglish, and English, and you can't possibly staff native speakers for every dialect. This is where Bolna comes in.

Bolna is a Voice AI platform purpose-built for the Indian market. Unlike generic AI solutions that treat India as an afterthought, Bolna is designed from the ground up to understand the nuances of Indian languages and business workflows. Whether you're handling customer inquiries in Hindi, conducting recruitment calls in Hinglish, or managing shopping cart recoveries in Tamil, Bolna speaks your customers' language—literally.

What sets Bolna apart is its speed and flexibility. The platform delivers less than 300ms response latency, meaning conversations feel natural and fluid rather than robotic. Behind the scenes, Bolna orchestrates over 20 ASR (automatic speech recognition), LLM (large language model), and TTS (text-to-speech) providers, giving you the freedom to choose the best combination for each use case. This model-agnostic approach means you're not locked into a single vendor—you can optimize for cost, accuracy, or speed depending on the conversation type.

The platform has already earned the trust of over 1,000 enterprise customers handling more than 500,000 voice conversations monthly. Notable clients include Physics Wallah, Spinny, Futwork, GoKwik, Awign, and Knot Dating—companies that rely on Bolna for critical customer interactions. Bolna is also backed by Y Combinator's 2024 batch and secured $6.3M in seed funding led by General Catalyst, earning recognition as one of YourStory's Tech30 2025 most promising startups.

Bolna's Core Features

What can Bolna actually do for your business? Let's break down the features that matter most for Indian enterprises.

Batch Outbound Calling at Scale lets you run thousands of AI-powered calls simultaneously. Whether you're launching a marketing campaign, screening hundreds of job applicants, or sending appointment reminders to thousands of customers, Bolna handles the load. The Scale plan supports over 75 concurrent calls, making it possible to reach entire customer bases in hours rather than weeks.

Multi-language Support is Bolna's strongest differentiator. The platform fluently converses in Hindi, Hinglish, Tamil, Telugu, English, and other Indian languages—plus major global languages. The AI automatically detects and switches languages mid-conversation, so your customers never feel forced to conform to your system's limitations. This matters enormously in a market where mixing languages is the norm, not the exception.

Custom API Trigger enables real-time data lookups during calls. Your AI agent can query order status from your e-commerce system, check appointment availability from your calendar, or update CRM records on the fly—all without missing a beat in the conversation. This transforms voice interactions from scripted dialogues into genuinely useful business transactions.

Human-in-the-Loop allows seamless escalation to human agents when conversations get complex. Rather than frustrating customers with rigid bot scripts, Bolna intelligently transfers high-value or complicated interactions to your team, complete with context so customers don't have to repeat themselves.

Model Flexibility gives you control over every aspect of the voice pipeline. Choose from 20+ ASR, LLM, and TTS providers. Need high-accuracy transcription for accented Hindi? Swap in a better ASR model. Want to reduce costs on high-volume notifications? Select a more economical TTS voice. Each call can use a different optimal configuration.

Workflow Integration connects Bolna to your existing tools through n8n, Make.com, Zapier, and direct API access. Automate data sync, trigger downstream actions, and build complex business logic without writing custom middleware.

Enterprise-Grade Deployment addresses the data sovereignty requirements of regulated industries. Choose India data residency to keep all information within the country, use US-based storage as default, or deploy on-premise for maximum control. This flexibility meets the compliance requirements of banking, government, healthcare, and telecom sectors.

Who's Using Bolna

Seeing how other companies use Bolna is the best way to understand if it's right for you. Here's a breakdown of real-world implementations across different industries.

E-commerce and Retail companies use Bolna for shopping cart recovery and customer engagement. GoKwik, a leading e-commerce optimization platform, achieved over 400,000 unique interactions using Bolna's AI agents. They handled peak volumes of 250+ concurrent calls for cart abandonment outreach, COD (cash on delivery) confirmation, and post-purchase surveys. The AI doesn't just read a script—it has real conversations that convert browsers into buyers.

Recruitment and Staffing teams rely on Bolna to scale hiring without scaling costs. Awign, a talent solutions company, reduced their recruitment costs by 65% using Bolna's AI interviewers. Their AI agents conducted thousands of screening calls, with interview durations averaging 6.8 minutes and peaking at 17.1 minutes—thorough enough to assess candidates, fast enough to scale. They handled 20 parallel interviews at peak and recovered 40% of "no-show" candidates through automated follow-ups. Meanwhile, Hyreo saw a 96.55% increase in call minutes and conducted over 10,000 AI-powered voice conversations, dramatically improving candidate experience while reducing hiring team workload.

Customer Support and Service operations use Bolna to provide 24/7 coverage without the expense of round-the-clock human teams. Futwork, a workforce management platform, runs over 10,000 daily calls with Bolna, handling 250+ concurrent conversations for national recruitment drives and candidate outreach. When conversations require human judgment, seamless escalation to human agents maintains service quality.

Revenue Recovery and Collections teams leverage Bolna to recover outstanding payments. Hypothesis, a collections platform, used Bolna to recover over ₹2.5 Crore (25 million INR) in revenue while launching over 300 SKUs. The AI handles initial outreach, payment reminders, and follow-up conversations—work that would require a large collections team otherwise.

Getting Started with Bolna

Ready to bring Bolna into your workflow? Here's how to go from sign-up to your first live AI call in under an hour.

Step 1: Create Your Account and Choose a Telephony Provider Sign up at bolna.dev and connect your preferred telephony provider. Bolna integrates with Twilio, Plivo, Vobiz, Exotel, and BYOT (Bring Your Own Telephony). You can purchase Indian local numbers directly through these providers to ensure your customers see a familiar local caller ID—a small detail that significantly improves answer rates.

Step 2: Build Your AI Agent You have two paths here, depending on your technical preference:

• No-code route: Use Bolna's visual Playground to design your agent. Drag and drop conversation flows, define prompts in your target language, and connect knowledge bases without writing a single line of code. This is perfect for rapid prototyping and non-technical teams.

• Code route: Use the REST API for full control. Define custom function calls, integrate with your internal systems, and build complex logic. Comprehensive API documentation at bolna.ai/docs makes integration straightforward.

Step 3: Connect Your Knowledge Base Upload documents—product catalogs, policy FAQs, pricing sheets, HR guidelines—and Bolna automatically builds a RAG (retrieval-augmented generation) knowledge base. The AI pulls accurate, up-to-date information during conversations, ensuring responses are always correct and current.

Step 4: Test Before Going Live Use Bolna's built-in testing tools to simulate conversations, review transcriptions, and audit AI responses. Test different language scenarios, edge cases, and escalation paths before releasing to real customers.

Step 5: Deploy to Production Deploy to cloud infrastructure or, if required, set up on-premise installation. Scale gradually—start with a pilot group, measure results, then expand.
