What is StartupHub.ai?

The world's #1 directory of AI startups, built on the leading intelligence layer for the startup ecosystem. We've been at this since 2018, long before “AI startup” was a category, trailblazing the idea that the ecosystem deserves real connective tissue between founders, investors, and clients. While the incumbents indexed deal terms and fund data, we obsessed over a harder question: what actually makes a startup succeed? We introduced data points few people thought mattered at the time, and bet they'd become the signals everyone relies on. Today millions of profiles across startups, investors, founders, and funding rounds are enriched daily by our AI agents, and our editorial team publishes original reporting the industry follows.

Who uses StartupHub.ai?

Founders use it to get discovered and reach the investors, buyers, and analysts already sourcing here. Investors use it to find deals early, research sectors, and track their portfolios. Sales and BD teams use it to find and verify founder and exec emails. Researchers and journalists use it to map competitive landscapes and track where the market is heading. If you need to understand the AI ecosystem, and its people, before everyone else does, this is where you start.

How do I list my startup, and why should I?

Click Submit Profile, paste your website, and our AI fills in the rest: description, sectors, funding stage, even your tech stack. Listing is $5/month or $40/year, cancel anytime. It costs a little, and it's worth a lot. A listed profile is how you get visibility and your first clients, and it's how you start ranking inside ChatGPT, Gemini, and Perplexity shortly after, that's our juice. The copycat directories can't say the same. Real builders only, we keep SEO farms and dev shops out by design.

Is it free? What do the paid plans include?

Yes, search, Market Map Maker, and reading any profile are free, and the same tools that rank us #1 on Google for the keyphrases we go after are free for you to use too. Listing your own startup is $5/month or $40/year. From there, Pro Lite ($30/mo) adds 50 tracked profiles with change alerts, verified founder emails, the bulk email finder, and 150 exports. Pro ($50/mo) doubles that to 100 tracked profiles and 500 exports. You can also Boost a profile from $2/day to ride the ad slider site-wide and lead the trending sidebars. Cheap, and genuinely powerful.

How does the email finder work?

Pro Lite and Pro members can surface and verify a founder's or exec's professional email straight from any profile. We search multiple sources for the most likely address, then verify it's actually deliverable in real time, not just well-formatted. Every result carries a confidence score, so you know what you're sending before you send it. Built for investor outreach, partnerships, and prospecting.

Can I track competitors and get alerts?

Yes. Add any startup, investor, or founder to a watchlist and get an email the moment something moves: new funding, a key hire, a launch, a news mention, or a score change. Pro Lite tracks 50 profiles, Pro tracks 100. Compare any two companies side by side and build unlimited lists to organize your research.

What is Market Map Maker?

A free visual tool for building competitive landscape maps. Generate a full map from one text prompt, reverse-engineer one from a screenshot, or import a CSV. Our own logo API and RAG fill in real profiles with clean square and horizontal logos. Drag and drop companies, switch between square, pill, and card layouts, and export to PNG, JPG, or PowerPoint, then embed it anywhere.

What makes your data different?

This is our edge, and our origin story. We were the first to map the AI tech stack itself: the models and algorithms a company runs, its cloud provider, whether it's GPU-heavy, and how it does inference. That's the kind of signal infrastructure leaders like Amazon and Nvidia use to target the right startups, and for a long time it lived on StartupHub alone. We were also first to profile the people behind the companies, tagging founders through lenses like AI expert and serial entrepreneur back when nobody else cared to dig that deep. Today it's a copied feature. Then we went further with predictive AI that identifies founders and companies before they have a website or any web presence, which is what powered the original Stealth Mode filter. We shipped it first; the rest of the category, Harmonic, Crunchbase, Dealroom, CB Insights, PitchBook, followed with their own. Our agents run daily across 700M+ entities, and we don't just retrieve data, we predict it. Not convinced? Try it free.

Agentic intelligence layer

Our agents read funding news, hiring signals, product launches, and filings around the clock, so every profile stays current without anyone touching a spreadsheet. Then the Lighthouse Engine traces a faint signal to a fully formed company profile: Palantir-grade identity resolution and graph-network technology that follows a bare domain to the live site, the company behind it, and the real people running it, every link independently verified. It's how we surface stealth startups before they ever announce.
