Who Should You Cold Email at a Startup? CEO, Founder, or HR?

Confused about who to cold email at a startup for a job or internship? Here's exactly who to contact at each stage — founder, CEO, or hiring manager — and why it matters.

Who Should You Cold Email at a Startup? CEO, Founder, or HR?

When you're cold emailing a startup for a job or internship, who you contact matters as much as what you say. Send your cold email to the wrong person at a startup and it sits in an inbox nobody checks. Send it to the right person and you get a reply within 48 hours.

Most students default to emailing "HR" or hunting for a generic jobs@company.com address. That's a mistake. Startups don't work like big companies. The org structure is flat, roles overlap, and the person who decides to hire you is usually NOT in recruiting.

Here's the exact playbook for who to cold email at a startup depending on how big they are — and how to find their contact information.

Why Who You Cold Email at a Startup Changes Everything

At a 500-person company, HR screens candidates. At a 10-person startup, the CEO is HR. The founder is the recruiter. The person replying to your email might also be the person you'd be working directly with.

That changes the calculus completely. You're not trying to pass a keyword filter or beat an ATS. You're trying to get a real person — someone who cares deeply about their company — to see you as someone worth 20 minutes of their time.

The right contact gives you a direct line to that decision-maker. The wrong contact means your email gets forwarded once, sits in a queue, and dies.

Early-Stage Startups (1–20 People): Email the Founder or CEO Directly

This is the most important rule in startup outreach: at small startups, always email the founder or co-founder first.

Why? Because they're the ones actually making hiring decisions. There's no recruiting pipeline. No HR layer. If the founder reads your email, likes your pitch, and thinks you'd add value, you're in.

At seed-stage or pre-seed startups, the CEO is often doing five jobs at once. They're not above reading cold emails from smart students — in fact, a lot of founders love getting a message from someone who's clearly done their research and sounds genuinely excited about the problem they're solving.

Who exactly to target:

How to find them: LinkedIn is your starting point. Search the startup name and filter by "Founder," "CEO," or "Co-founder." Crunchbase also lists founding team members. Once you have their name, tools like Hunter.io or Apollo.io can surface their email format.

Or use Chiaro, which automates the entire process — finding the right contact, personalizing the email, and sending it directly from your Gmail.

Mid-Stage Startups (20–100 People): Target the Hiring Manager or Department Head

Once a startup crosses around 20 people, things get more structured. The CEO is no longer in every conversation. There's usually a Head of Engineering, Head of Product, or VP of Marketing running their own team.

At this stage, you want to cold email the person who leads the team you'd be joining — not HR, not a generic recruiter, and not the CEO (who now has enough on their plate that your email is less likely to cut through).

If you're going for a software engineering internship, find the Head of Engineering or CTO. For a marketing role, look for the Head of Marketing or Growth. For product, go directly to the VP of Product or a Product Lead.

This person is close enough to the actual work to evaluate your pitch — and they have the authority to bring you on.

Who exactly to target at this stage:

What to avoid: Don't email a generic careers@ address, a recruiter you can't confirm is still active, or the CEO when there's clearly a functional manager below them. Your message will get re-routed at best, ignored at worst.

Later-Stage Startups (100+ People): HR and Recruiting Can Actually Help

Once a startup has scaled past 100 people, a recruiting function usually exists and actually works. At this stage, reaching out to a recruiter or HR contact is no longer the dead end it is at earlier stages — especially if the company has posted a role you're applying to.

That said, sending a second cold email directly to the hiring manager in parallel is still worth doing. A message that says "I also applied through your careers page but wanted to reach out directly" shows initiative and makes you stand out from the pile of resumes sitting in the ATS.

At Series B and beyond, the CEO rarely makes individual hire decisions. But a sharp email to the right VP can still fast-track you past the standard recruiting process.

How to Find Who to Cold Email at a Startup

Here's the system that actually works:

  1. LinkedIn: Search the company name plus the function you're targeting. Filter by seniority — Director, VP, Head of. Confirm they're still there by checking their current role.
  2. Crunchbase or AngelList/Wellfound: Lists founding team members and key executives with titles.
  3. Hunter.io or Apollo.io: Once you have a name, these tools find or verify the company's email format and sometimes the individual address directly.
  4. Twitter/X: Many startup founders are active and will respond to a thoughtful reply or DM. Not always, but often enough to try.
  5. Chiaro: Skip the manual research entirely. Chiaro finds the right contact at startups you're interested in, personalizes a cold email, and sends it from your Gmail automatically — with follow-ups built in.

FAQs

Who is the best person to cold email at a startup for an internship?

For startups under 20 people, email the founder or CEO directly. For startups between 20–100 people, find the department head for the team you'd be joining. The goal is to reach the person who would actually work with you — not HR, not a generic careers inbox.

Is it okay to cold email the CEO of a startup for a job?

Absolutely — especially if the company is small (under 20 people). Many startup CEOs genuinely like hearing from ambitious students. Keep your email short, specific, and respectful of their time. A thoughtful cold email to the right person stands out far more than any online application.

Should I email HR or the founder at a startup?

If the startup has fewer than 50 people, skip HR and go directly to the founder or the relevant department head. There's almost certainly no formal recruiting pipeline, and your outreach will carry much more weight coming directly from you rather than routing through a generic inbox.

How do I find someone's email at a startup?

Use LinkedIn to identify the right person by name and title, then use Hunter.io or Apollo.io to find their email. Most startup addresses follow simple patterns like firstname@company.com. You can also use Chiaro, which handles the contact discovery and personalized outreach automatically.

What if I can't find the right contact's email?

Try Twitter/X — many founders are active and surprisingly responsive to direct messages from people who clearly know what they're doing. LinkedIn messages are another fallback, though response rates tend to be lower. When in doubt, a specific cold email to a general inbox with the right person's name in the subject line ("For [Name] — Interested in Helping with Growth") is better than not reaching out at all.
