How to Find AI Engineering Leaders at Seed & Series B Startups in 2026

Quick Answer: The fastest way to find AI engineering leaders at seed and Series B startups is Origami — describe your ideal customer in one prompt, and the AI agent searches the live web, enriches contacts, and delivers a verified list with emails, phone numbers, and company details. No multi-step workflow building. No static database gaps.

Last week, a sales director at an AI observability company told me she spends hours every morning manually cross-referencing Crunchbase, LinkedIn Sales Navigator, and Apollo to build a list of 20 VPs of Engineering at Series A AI startups. Half the contacts bounce. The other half have already left the company. She's juggling four tabs, and her CRM is full of outdated titles like "Head of ML" when the person is now VP Engineering.

That's a common pain point in 2026. Traditional databases were built for enterprise sellers looking for VPs at 10,000-person companies, not for finding the 3-person AI team that's building the next generation of agentic infrastructure at a 20-person startup.

If you sell to AI engineering leaders — the CTOs, VPs of Engineering, Heads of AI, and even senior founding ML engineers who make technical purchasing decisions at seed through Series B companies — you need a prospecting approach that matches how these companies appear (and disappear) online.

Why are AI engineering leaders at early-stage startups so hard to find?

Early-stage AI startups have a small digital footprint. The CTO might not have a LinkedIn profile with a "CTO" title; they might be listed as "co-founder" or "engineer." Funding data from Crunchbase lags by weeks or months. Job postings for AI leads appear for a few days, then vanish. And because these companies grow fast, org charts change monthly — someone who was Head of ML in January becomes VP of Engineering by March.

Standard B2B databases struggle here. They rely on periodic refreshes, so they miss job changes and newly created roles at companies that barely existed six months ago. If you're targeting companies that raised a seed round yesterday, a static database might not even list them.

What's the best tool to find AI engineering leaders at seed and Series B companies?

Origami solves the core problem by combining live web search with AI data orchestration. You type "find VP of Engineering contacts at US-based AI startups that raised seed or Series A in the last 12 months, working on agentic systems or model orchestration," and the agent searches Crunchbase, LinkedIn, company websites, news articles, and job boards in real time. You get a table with names, emails, phone numbers, and company details — no manual workflow setup.

Here's why that's different from clicking through Apollo filters or building a Clay waterfall. Origami starts free with 1,000 credits and no credit card required. Paid plans start at $29/month for 2,000 credits. You're paying for a live exploration, not a database snapshot.

Other tools to consider (and where they fall short for early-stage AI)

If you want to understand the landscape, here are the most common tools sales teams use to find AI engineering leaders, with honest strengths and weaknesses:

Tool	Free Plan	Starting Price	Best For	Main Limitation
Origami	Yes (1,000 credits)	Free, then $29/mo	Live web search for any ICP in one prompt; fresh data on startups	No outreach functionality (export list and use your existing tools)
Apollo	Yes (limited)	$49/mo (annual)	Contact-centric database for broad tech roles	Not designed for roles outside standard LinkedIn job titles; data can be stale for startups
Clay	Yes (500 actions/mo)	$167/mo for Launch plan	Building complex data enrichment workflows if you have time	Steep learning curve; requires building multi-step tables; best for ops teams, not reps
LinkedIn Sales Navigator	No free plan	$79.99/mo (annual)	Browsing and identifying people by title and company	Doesn't provide emails or phone numbers; you still need an enrichment tool

Apollo and ZoomInfo are static databases built primarily for enterprise sales; they were not designed to index rapidly changing seed-stage companies where the CTO might be listed as a co‑founder on LinkedIn. Clay can scrape the web but requires building a 20-step table; most reps don't have time for that.

Origami works because it acts as a single‑prompt agent that adapts its research method to the target. For AI startup leaders, it checks funding announcements, recent job postings for engineering leadership hires, conference speaker pages, and GitHub orgs — not just a LinkedIn title.

How do you define your ICP for AI engineering leaders?

Before you search, get specific about who you need. At early-stage startups, the person who buys your tool might not have "VP Engineering" in their bio. Map the real buying signals:

• At seed stage (1–20 employees): The CTO or a senior founding engineer often makes all technical purchasing decisions. Look for job titles like "Founding Engineer," "Head of AI," "ML Lead," or simply "Engineer" if they're a co-founder.
• At Series A (20–80 employees): A VP of Engineering or Head of Engineering emerges. They may still write code, so they're both user and buyer. They're active on X/Twitter, Discord communities, and conference speaker lists.
• At Series B (80–200 employees): The org chart solidifies. You'll find a VP of Engineering, sometimes a CTO plus a VP Eng, and specialized AI/ML leads. They start showing up in vendor directories and Crunchbase profiles.

Using a live web tool like Origami, you can prompt for "AI startup, seed funded, 5–20 employees, has an engineer who speaks at ML conferences or contributes to open-source projects" — and the agent finds those people even if their LinkedIn doesn't have the right title. That's the kind of search you can't run in a static database.

What are the best data sources for early-stage AI startups?

Relying on a single database leaves gaps. The most effective prospecting for AI engineering leaders combines multiple live sources:

1. Crunchbase and PitchBook for funding signals: Filter by recent rounds under two years old, AI/ML category, US-based. This gives the list of companies.
2. LinkedIn for org chart hints (not contact data): Use Sales Navigator to spot technical employees who post about their work, but don't expect their profile to have accurate email.
3. Company websites and job boards: Many startups list their CTO email on the team page, or they post jobs that reveal who the hiring manager is.
4. Conference speaker lists and GitHub orgs: AI leaders often speak at O'Reilly AI, NVIDIA GTC, or local meetups. Their GitHub contributions are public. This is signal that they're technical and have budget influence.
5. Live web search (via Origami): Instead of manually checking each source, you give one prompt: "Find the AI engineering leaders at these 50 seed‑stage startups, with verified emails and any public phone numbers."

Sales conversations we've studied at Origami reveal that teams spend hours on Google Maps scrapes and manual CrunchBase checks, only to find that the CTO left three months ago. A live search reflects what exists on the web right now, not what was true six months ago.

How do you verify contact data and avoid bounces?

Sending to outdated or guessed emails is the fastest way to burn your domain reputation. Use a multi‑step approach:

• Run contacts through an email verification step. Origami does this automatically as part of enrichment, so the emails you export are already checked for validity.
• Cross‑reference a sample manually. For high‑value targets, check the company's website team page or their GitHub commit history.
• Use a tool to detect "catch‑all" domains. Some startup email servers accept all mail, which inflates deliverability risk. Origami flags these.
• Don't rely on a single source for phone numbers. If you need mobile numbers for cold calling, use a waterfall approach — Origami web search first, then supplement with your dialer's existing enrichment if needed.

One sales leader told us: "I had my list yesterday, and there were probably five bounced emails. Some of these emails were from previous jobs." That's the cost of using static data for dynamic startups. Live enrichment reduces that risk.

What outreach strategy works for AI engineering leaders?

Once you have a verified list, tailor your outreach. AI engineering leaders at startups are technical, time‑starved, and allergic to generic "touching base" emails. Tactics that work in 2026:

• Reference their recent technical decision. If they just chose a model provider or open‑sourced a tool, mention it. Use tools like Origami to enrich that context.
• Send via email and LinkedIn, but stagger. Email first, then a LinkedIn connection with a note referencing the email.
• Keep it short. They read on mobile. No more than four sentences.
• Use signal‑based outreach. Contact them when they've raised funding, posted a new AI role, or appeared on a podcast. Origami's live web search can surface these triggers.
• Don't automate blindly. Personalization matters. If you use sequencing, make sure each step feels human.

The tools that handle outreach (Outreach, Salesloft, HubSpot) are good for execution, but the quality of the list determines whether they work. Start with a targeted, accurate list, and your reply rates will improve regardless of the sending tool.
