ATDb is in Beta

ATDb — The AdTech Database — is a one-person project built to answer a question I kept running into: who are all the players in AdTech, and how do they connect?There wasn't a single place that mapped out the companies, the people, the deals, and the news in one interconnected view. So I started building one.

What you're looking at is a working beta with real data — over 3,000+ company profiles (100% AI-enriched), 800+ people, 400+ industry deals and moves, 8,000+ news articles from 37 RSS feeds, 31,000+ mapped relationships, and 55categories organizing the AdTech landscape. But it's not finished. Pages will change. Features will appear (and sometimes disappear). That's the nature of building in public.

The goal is to make ATDb the go-to reference for anyone doing landscape mapping in advertising technology. If you're trying to understand a category, research a company, or figure out how the ecosystem fits together, this should be the first place you check. Think IMDb, but for AdTech.

What's Built

ATDb has gone from a concept to a full-featured platform. Here's what's live:

  • Company Profiles— detailed pages for 3,000+ AdTech companies with summaries, business models, tech stacks, funding history, key people, competitive landscape, and tier classifications from S-tier (Core Platforms) to D-tier (Extended Ecosystem)
  • People & Relationships — 800+ industry professionals with role histories and 31,000+ mapped relationships connecting companies, people, events, and news
  • News & Deals— daily automated ingestion from 37 RSS feeds (AdExchanger, Digiday, MarTech, Adweek, and more) plus 400+ tracked acquisitions, mergers, and industry moves
  • Ecosystem Graph— interactive network visualization of the entire AdTech ecosystem, filterable by tier and category, with drill-down detail panels
  • Compare & Insights— side-by-side company comparison, category deep-dives with AI-generated overviews, and industry-wide analytics
  • Watchlist— save companies and people to a personal watchlist with optional daily digest emails when watched entities change
  • Ask ATDb— AI-powered natural-language Q&A grounded in ATDb data with citations linking directly to entity profiles
  • Weekly Insights— AI-generated industry analysis with category deep-dives, trend spotlights, and daily highlights
  • Accuracy Voting— vote on whether entity sections look accurate, flag concerns, and help prioritize what gets reviewed and improved
  • Contributor Profiles— public profiles and leaderboard tracking approved edits, entities improved, and sections rated
  • AI Agents — 56 automated agents handling discovery, enrichment, categorization, news extraction, relationship mapping, and data quality

Community Editing

ATDb is a community-edited database. If you work in AdTech, you probably know things our AI doesn't — a company's correct headquarters, a recent leadership change, a product that launched last week. We want that knowledge in the database.

Registered users can suggest edits to any entity on ATDb. Every edit goes through a review process before it's published. As you build a track record of quality contributions, you'll earn higher trust levels with expanded capabilities.

Trust Levels

  • New User— create an account and start suggesting edits. All edits are reviewed by a moderator before publishing.
  • Contributor— earned after consistent quality contributions. You'll get a badge on your profile.
  • Trusted Editor— earned after a sustained track record. Some edits on non-protected fields can be auto-approved.
  • Moderator— appointed by administrators. Can review and approve edits from other contributors.

What We're Looking For

  • Factual corrections — wrong headquarters, outdated employee counts, incorrect founding years
  • Missing information — website URLs, LinkedIn profiles, stock symbols
  • Better descriptions — more accurate summaries, clearer business model explanations
  • Source-backed claims — linking to press releases, SEC filings, or news articles

We ask that all contributions be factual, neutral, and written in the third person. Promotional language, unverifiable claims, and competitive sabotage will be rejected. If you have a conflict of interest (e.g., editing your own company's profile), just disclose it and stick to verifiable facts. Full details are in our Community Guidelines.

Feedback & Feature Requests

Found a bug? Have an idea for a feature? The Feedback page lets you submit feature requests and bug reports, vote on existing ones, and follow along as things get built. It's the best way to shape what ATDb becomes.

Get Involved

ATDb is currently in invite-only beta. If you have an invite code, you can join here. If you don't have a code yet, join the waitlist below and we'll reach out when spots open up.

Join the Waitlist

Be among the first to know when the next wave opens. No spam — just an invite when it's your turn.

Where this goes depends on traction and support. Right now it's me, a database, and Claude. If people find it useful, I'll keep investing in it — more data, better pages, eventually an API. If you have thoughts, feedback, or want to contribute, I'd genuinely like to hear from you.
