OnGravy
Quotable facts, founder bio, and assets for journalists covering AI in Indian accounting + tax compliance. Last updated: September 2026.
One-paragraph summary
OnGravy is an AI-native accounting platform for Indian SMBs and Chartered Accountants, live since 2026. The system implements a six-layer hallucination defence on top of the Anthropic SDK, with hybrid retrieval (pgvector + BM25 + Voyage rerank) over indexed government regulations, so every answer is grounded in cited regulation or refused. Built since early 2025 by Pratik Revankar.
Quotable facts
- Indian-domain AI accounting platform for Chartered Accountants (CAs) + SMBs
- Tax engines for 61 jurisdictions — India is the deepest, Live product; UAE, Saudi Arabia & Singapore live in the UI, the rest in Beta
- 60+ agentic tools spanning GST, TDS, audit, payroll, ROC, e-invoicing, e-way bill
- An extensive pure-compute test suite covering the tax engines end-to-end
- Six-layer hallucination defence: retrieval grounding → schema-constrained output → referential probes → idempotent writes → audit log → cost ceiling
- Hybrid retrieval pipeline: pgvector HNSW + tsvector BM25 + Reciprocal Rank Fusion + Voyage rerank-2.5-lite
- Per-business cost cap of ₹500/month enforced via cost-aware Haiku → Sonnet → Opus model routing
- A live MCP server (OAuth-scoped, draft-only writes) exposes the accounting tools to Claude Desktop / Cursor / Zed; the reusable primitives are being packaged for open source
- Building a public benchmark for AI agents on Indian tax & compliance tasks

Common questions
How is OnGravy different from Tally / Zoho Books / QuickBooks?
OnGravy is AI-native — the agent itself is the primary interface. Existing platforms have bolted on AI assistants on top of forms-and-tables UIs. OnGravy treats accounting as a tool-calling problem the agent executes, with cost guardrails and hallucination defence built in from the ground up.
Is it safe to let an AI prepare tax filings?
The six-layer hallucination defence + a pre-filing validation gate + sandbox mode for non-production environments make it safer than CA staff entering data manually. Every claim is grounded in indexed government regulations with citations; every mutating action is logged in a hash-chained audit trail. The CA reviews and signs the final return.
What is OnGravy’s business model?
Subscription SaaS. ₹15-25k/year per CA + per-client billing for the design-partner phase; expansion to direct-SMB tier after PMF.
Are you funded?
Bootstrapped. Pre-seed conversations begin after first 5 paying design-partner CAs.
What’s open source?
The agentic AI primitives (RRF, eval metrics, model router, prompt-cache planner, MCP wire format) live in @ongravy/agent-kit. The MCP server is @ongravy/mcp-server. The IndianTaxAgentBench benchmark + eval harness are open-source. The main accounting application is closed-source.
