Event discovery is broken on purpose: Eventbrite killed public search and Luma never had it. These tools and agents are how we rebuild a founder-readable event pipeline anyway — and how we follow up without losing the room in a spreadsheet graveyard. Last updated: August 31, 2026. Reviewed weekly. For which events are worth the ticket this quarter, use our events & deadlines living page — this page is about tools, not dated listings.

Which tools help discover startup events?

6 listed

Crawlee

Rolling
What it is
Crawler framework for Luma / Eventbrite pages
License / cost
Apache-2.0

The practical OSS answer when APIs refuse to exist. You still need a signed-in session for some sites — automate carefully.

Firecrawl

Rolling
What it is
URL → markdown for event pages
License / cost
AGPL

Fast way to turn organizer pages into agent context. Great for weekly refresh scripts.

Cal.com

Rolling
What it is
Scheduling for 1:1 event follow-ups
License / cost
OSS core

Book coffee chats before the badge heat fades. Open source means you can embed it on your landing page.

ICS / iCal OSS parsers

Rolling
What it is
Parse calendar feeds
License / cost
Mixed

Many conferences publish `.ics` quietly. Parsing beats screenshotting agendas.

OpenStreetMap + Overpass tools

Rolling
What it is
Geo event experiments
License / cost
ODbL

Niche, but useful for hackathons and city tech weeks with weak SEO.

Which agents automate event research & summaries?

5 listed

n8n event scrape workflows

Rolling
What it does
Scheduled scrape → Slack/email digest
Setup cost
Self-host time

The founder-friendly automation layer. Template: Luma city page → filter keywords → Friday digest.

Playwright MCP + Claude

Rolling
What it does
Browser-driven event extraction
Setup cost
Medium

Use when sites block simple HTTP fetch. Slower, more reliable on JS-heavy calendars.

LangGraph research agents

Rolling
What it does
Multi-step "find → dedupe → rank"
Setup cost
Dev time

Overkill for one city; worth it if you cover multiple regions for a community newsletter.

Open WebUI tools

Rolling
What it does
Self-hosted chat + tool hooks
Setup cost
Medium

Good internal "what's on this week?" bot for your team Slack — not public product unless hardened.

Huginn

Rolling
What it does
Self-hosted monitoring agents
Setup cost
AGPL

Old but stable pattern: watch URLs, emit events when organizers change dates.

Which tools help follow up after events?

5 listed

Monica

Rolling
What it is
Personal CRM
Best for
Remembering who you met

Tag people with event name + date the same night. Future you will not remember booth conversations.

Twenty CRM

Rolling
What it is
Team CRM
Best for
Shared pipeline after conferences

Import CSV from badge scans within 48 hours or conversion drops sharply.

Listmonk

Rolling
What it is
Email follow-ups
Best for
"Great meeting you at X" sequences

One personal paragraph + automated logistics beats a generic blast from no-reply@.

QR / vCard OSS tools

Rolling
What it is
Contact exchange
Best for
Fast booth networking

Low-tech win: generate a vCard QR so investors actually save your contact.

Notion/Obsidian export scripts (OSS)

Rolling
What it is
Notes → CRM rows
Best for
Capturing session takeaways

Your event notes are worthless if they stay in a notebook app — script the export.

Frequently asked questions

Why not just use Luma search?
Luma's consumer search is fine logged-in; there is no stable public API for founders to automate against. Plan on browser-level tooling or manual sweeps.
Eventbrite API?
Public event search API was deprecated years ago. Anyone selling "Eventbrite API event discovery" without caveats is outdated.
How does this differ from the deadlines living page?
That page lists specific events and grants with dates. This page lists tools to build your own radar.
How often is this page updated?
Weekly, same cadence as our other living guides.
