India's first hackathon powered by Lemma SDK - open-source infrastructure for building agentic apps that run real work.
The total prize pool is ₹1,00,000, split across first, second, and third place.
Build a working agentic app with Lemma - open-source infrastructure for coding agents.
Use Lemma SDK as the infrastructure layer for your product. Lemma provides components like datastores, document stores, agents, workflows, functions, and integrations.
Bring your own IDE, AI coding tool, API key, builder platform, and hosting or deployment setup.
Pick a specific user, pain point, and workflow. Keep it useful and demoable.
See problem statementsChoose a company challenge, a suggested use case, or your own problem.
Polish is optional. The core loop should work end-to-end.
Build from our suggested problem statements or bring your own idea. The goal is simple: solve a real problem.
Small startups receive customer issues across email, forms, and Slack. Build an AI support desk that can triage issues, search product docs, draft replies, track ticket status, and escalate important cases for review.
Startup development teams receive bugs, feature requests, and customer complaints across GitHub, Slack, email, and support channels. Build an AI operator that turns messy feedback into organized issues, suggests priority, creates reproduction steps, links related bugs, tracks fixes, and prepares release notes.
Small engineering teams ship fast but often miss broken flows, missing docs, untested edge cases, migration risks, and release notes. Build an AI assistant that reviews PR context, checks a release checklist, flags risks, prepares test plans, and creates release notes.
Meetings often end with decisions, tasks, and promises that are never properly tracked. Build an AI operator that turns meeting notes or transcripts into action items, owners, deadlines, follow-ups, and a live execution board.
Founders, freelancers, and early sales teams often forget who to follow up with, what was promised, and which leads are warm. Build an AI CRM that tracks conversations, summarizes lead history, suggests next actions, drafts follow-ups, and keeps a priority queue.
Students and recent graduates apply to many jobs and internships across portals, referrals, emails, and LinkedIn. Build an AI command centre that tracks applications, parses job descriptions, suggests resume changes, drafts recruiter messages, and prepares interview notes.
Students struggle to turn notes, PDFs, lectures, and doubts into a clear learning plan. Build an AI learning companion that organizes study material, identifies weak topics, creates revision plans, generates practice questions, tests, and tracks learning progress.
People have commitments scattered across email, calendar, notes, documents, and memory. Build a personal command centre that tracks open loops, deadlines, recurring tasks, important documents, reminders, and follow-ups across everyday life.
Creators and young builders collect ideas across notes, screenshots, bookmarks, tweets, and conversations but rarely turn them into consistent output. Build an AI backoffice that captures ideas, clusters them into themes, drafts posts or scripts, manages a content queue, and prepares work for review.
Most note-taking systems store information but do not help people act on it. Build an AI second brain that connects notes, files, links, and ideas; extracts useful insights; surfaces forgotten context; and helps turn knowledge into tasks, drafts, or decisions.
Most software records what happened. Lemma is infrastructure for software that actually does the work - combining structured data, AI agents, automated workflows, and custom interfaces in one environment.
The SDK is open-source and locally runnable. It gives you the building blocks to ship agentic applications, multi-step workflows, and AI-powered products - without stitching together five different APIs.
Same day the hackathon begins - everyone starts fresh.
From registration to results in less than a month.
Judges weight real-world utility above everything else.
Your submission goes to work for you - matched to AI Product Engineer and AI Product Manager roles at partner companies.
Our panel reviews all submissions for problem clarity, product thinking, and execution quality.
Top builders are evaluated not just on what they built, but how they scoped and defended their decisions.
We match shortlisted candidates to AI Product Engineer and AI Product Manager roles at partner companies based on skills, product thinking, and role fit.
Your resume, project summary, and a written rationale for the match go directly to the hiring team - no cold applications.
Partner companies review your profile and invite you directly for a first-round interview. No CV screening, no recruiter filters.
No placement fees. No commissions. We introduce you - what happens next is between you and the company.
Top 10 teams get the chance to keep building - with the Lemma team behind them.
The top 10 teams or individual builders from the hackathon are invited to continue developing their project.
Two more weeks to refine and develop your submission into a full-fledged product - with direct guidance from the Lemma team on architecture, SDK usage, and product decisions.
All participants who complete the project track receive a verified certificate of contribution - a real credential, not participation filler.
The strongest projects are published on the Lemma website as community templates - discoverable by everyone building on the SDK.
Everything you need to know before registering.
No. The SDK launches publicly on June 24 - everyone starts fresh. Docs, starter templates, and community support are available from day one.
Yes. Participants must bring their own development setup. Lemma provides the open-source SDK, starter examples, and documentation, but not an IDE, coding agent, model API key, or hosting environment.
You can use any setup you prefer: Codex, Claude Code, OpenCode, Cursor, Windsurf, VS Code, Replit, Emergent, or another builder platform. Lemma SDK is the infrastructure layer you build with, especially for components like datastores, document stores, agents, workflows, functions, and integrations.
The core loop must work end-to-end and be demonstrable in a screen recording. Polished UI isn't required - it just needs to do the thing it claims to do.
No. This hackathon is for developers, product thinkers, operators, and students. You can use your own IDE or AI coding agent with Lemma SDK to build end-to-end agentic apps. What matters is whether you can define a real problem clearly and ship a useful working product.
A form with: the problem you solved, your solution approach, a screen recording of the product in action, and team details. No decks required.
Yes. Solo and teams of up to 3 are both eligible. All prizes and tracks apply equally.
If you're in the top 10, your profile goes to the relevant partner companies with a written rationale - no separate application needed.
An AI startup building at the intersection of AI and real-world workflows. We've spent the last few years figuring out how AI can move beyond chatbots and actually help teams operate - that led us to Lemma, open-source infrastructure for AI-native software.
IIT Kharagpur alumni on their second startup, having worked in and built products at some of India's leading companies. We built Lemma because we lived the gap ourselves - and got tired of patching it with spreadsheets.
The hiring track isn't a formality. We're invested in putting the right builders in front of the right companies - it's the kind of break we wished existed when we were starting out.
Rolling registrations are open from June 8 to June 29. The SDK launches June 24 and the build window runs June 24-30.
