How to Find AI Agent Startups at Series A and Series B (2026)

Quick Answer: To find AI agent startups at Series A and Series B, set Crunchbase Pro funding alerts for "AI agents" and "agentic AI" categories ($5M–$50M range), track monthly announcements via TechCrunch's AI coverage, pull investor portfolio pages from a16z, Coatue, and Index Ventures, then enrich with Origami for verified founder and VP-level contacts. In a single Origami search, we found 148 Series A/B AI agent companies with GTM contacts.

The AI agent startup segment is the hottest category in venture right now — and one of the most valuable B2B prospecting targets for anyone selling infrastructure, developer tools, sales software, recruiting platforms, or GTM services. Series A and Series B AI agent companies have proven their core technology, closed real funding, and are now scaling fast. They hire quickly and buy actively.

The challenge: AI agent companies are being founded faster than any database can track them. Here's how to stay current.

Why AI Agent Startups Are Different from Other Tech Targets

"AI agent" is a broad term — it covers companies building autonomous workflows, multi-agent orchestration systems, domain-specific AI assistants, and everything in between. When prospecting, you need to be more specific:

• Horizontal agent platforms (e.g., agents that automate any business workflow): Customers are enterprises, pricing is enterprise, buying cycle is 3–6 months
• Vertical agent products (e.g., AI SDRs, AI legal assistants, AI healthcare coordinators): Customers are mid-market, faster sales cycle
• Agent infrastructure (e.g., orchestration frameworks, LLM routing, agent observability): Customers are developers and AI teams at companies building agents

Knowing which sub-segment you want changes where you look and who you target.

Source 1: Crunchbase Funding Alerts

Crunchbase is the most comprehensive index of funded AI agent companies. Set up Pro alerts with:

• Category: "Artificial Intelligence" + "Enterprise Software" OR search for "agent" in company description
• Round type: Series A, Series B
• Amount: $5M–$80M (captures most Series A/B range for AI)
• Date: Last 90 days
• Keywords in description: "agent," "agentic," "autonomous," "workflow automation"

Crunchbase Pro at $49/month is the most efficient way to do this at scale. The free tier supports one-time searches but not automated alerts.

In Q1 2026, Crunchbase showed 40–50 new AI agent funding announcements per month at the Series A/B stage. That's a steady stream of ~500 companies per year that just closed a round and are actively building.

Source 2: TechCrunch + VentureBeat AI Coverage

TechCrunch and VentureBeat cover almost every Series B+ funding announcement and a solid percentage of Series A announcements in AI. Their daily newsletters ("The Daily Crunch" and "VentureBeat AI") are a reliable signal source.

Efficient workflow: Subscribe to both newsletters. When you see an AI agent funding announcement, immediately run the company through Origami for founder and GTM lead contacts. The window right after announcement is when founders are most reachable — they're on a press high, responding to inbound, and in expansion mode.

One customer selling sales intelligence tooling to AI startups told us: "I used to read the TechCrunch funding roundup on Mondays and manually research every company. Now I paste the company names into Origami and have enriched contacts in 10 minutes. I sequence the founders the same day as the announcement — nobody else is that fast."

Source 3: Investor Portfolio Pages

The top AI agent investors publish their portfolios publicly. These are pre-qualified lists of well-funded AI companies at exactly the stage you want.

Key AI agent investor portfolios to monitor:

• a16z — maintains a public portfolio filtered by category; their "AI" filter includes many agent companies
• Coatue Management — AI-heavy portfolio, several agent companies per vintage
• Index Ventures — European and US AI coverage, portfolio visible on indexventures.com
• Spark Capital — significant AI agent portfolio (early investors in Cursor, other AI devtools)
• General Catalyst — "AI-native" focus in recent vintages

Cross-reference these portfolios quarterly. New additions are recent investments; filter to companies in the 50–500 employee range for Series A/B timing.

Source 4: LinkedIn Company Searches

LinkedIn's company search lets you filter by "founded" date, industry, and keywords in description. For AI agent companies:

• Industry: "Technology, Information and Internet"
• Keywords in "About" section: "AI agent" OR "agentic" OR "autonomous AI"
• Founded: 2022–2024 (captures companies at the right stage for Series A/B now)
• Headcount: 10–200 (post-seed, pre-scale)

This surfaces companies not yet in Crunchbase and not yet covered by press. The limitation: you won't know funding stage from LinkedIn alone. Cross-reference with a quick Crunchbase check to confirm they've raised a Series A.

Enriching AI Agent Startup Contacts with Origami

Once you have a list of company names (from Crunchbase, TechCrunch, or investor portfolios), Origami handles the enrichment step:

Prompt example:

"For each company in this list [paste company names and websites], find the CEO, CTO, VP of Sales, VP of Marketing, or Head of GTM. These are AI agent companies that just raised Series A or Series B. Return verified emails, phone numbers, and LinkedIn URLs. Flag any company that is actively hiring for GTM or sales roles."

In a recent test, we ran 78 AI agent companies from a Crunchbase export through this prompt. Origami returned:

• 71/78 companies with at least one confirmed contact (91%)
• 148 total contacts across all companies
• 34 companies flagged as actively hiring for GTM roles

Apollo returned contacts for 49 of the same 78 companies (63%), with a higher rate of stale emails.

Comparison: AI Agent Startup Data Sources

Source	Coverage	Freshness	Contact Info Included	Best For
Crunchbase Pro alerts	High	Real-time	Company-level only	Funding signal
TechCrunch / VentureBeat	Medium	Real-time	None (need Origami)	Announced rounds
Investor portfolio pages	High (within portfolio)	Quarterly updates	None	Pre-qualified lists
LinkedIn company search	Medium	Real-time	None	Non-announced companies
Apollo	Low–Medium	Lagging	Moderate	Post-announcement
Origami	High	Real-time	Yes (email + phone)	Enrichment + discovery

What to Pitch to Series A/B AI Agent Companies

Getting the contact is step one. Getting a response is step two.

Series A/B AI agent founders and VPs are busy. They're running a sprint: prove product-market fit, hire fast, close enterprise pilots, raise Series B or C. They don't have time for generic outreach.

What resonates:

• Specificity about their use case: "Saw you're building AI agents for healthcare intake — we've helped 3 other companies in that space with [specific thing]"
• Peer social proof: "Your YC batchmate [company name] uses our product for [specific outcome]"
• Speed: They want to test and decide fast. "15-minute demo, free trial same day" outperforms "let's schedule a discovery call"
• Technical credibility: Founders and CTOs at AI companies will Google you. Make sure your product has docs, a GitHub, and something real to show.

The Bottom Line

Finding Series A/B AI agent startups at the right time comes down to a monitoring + enrichment workflow: Crunchbase alerts for funding signals, TechCrunch/VentureBeat for press coverage, investor portfolio pages for pre-qualified lists, and Origami for enriched founder and GTM contacts.

The companies that just raised are the highest-intent window. Run your enrichment fast and reach out within the first two weeks. The reps who get there first win the meeting.
