Onboarding Checklist for a 10-Person Startup (No HR Person Required)

A good startup onboarding checklist covers five things: HR record, tool access, pre-boarding communication, day one orientation, and a 30-day check-in cadence. You don't need an HR team to run it — you need a written process with named owners, not one that lives in the founder's head.

Why Founder-Run Onboarding Breaks

At 5 people, the founder walks every new hire through everything personally. That's fine. At 10, it starts to crack. At 15, it's already broken — you've got one engineer who got a great first week and two who spent theirs waiting for tool access that nobody remembered to set up.

The failure mode is almost always the same: no one owns it, nothing is written down, and the process lives entirely in someone's memory. When that person is out, or just busy, the new hire absorbs the cost.

The fix isn't an enterprise onboarding program with 47 steps. It's a checklist that runs the same way every single time — regardless of who's doing the onboarding — and assigns every task to a specific person before the new hire shows up.

Before Day 1: The Pre-Boarding Checklist

The biggest onboarding wins happen before the hire ever shows up. If you're still figuring out tool access on their first morning, you've already lost the day.

1. Create Their HR Record

Add the new hire to your HR system (or at minimum a structured sheet) before their start date: name, role, start date, employment type, manager, and contract details. This record is the source of truth — it determines what tools they need, what their onboarding flow looks like, and what offboarding will require when they eventually leave.

If this lives in a spreadsheet no one updates, you're setting yourself up for gaps.

2. Provision Tool Access by Role

Make a role-specific list of every tool this person needs on day one. Engineers need a different set than designers, and salespeople need a different set than both. Don't use a generic all-tools list — it creates confusion about what's actually required.

A typical breakdown:

Everyone: Email, Slack, internal wiki or company docs, password manager
Engineers: GitHub, Linear (or Jira), Vercel or AWS console, dev environment creds
Designers: Figma, Notion, any brand asset storage
Ops / Sales: CRM, billing tools, relevant Notion databases

One thing most startups don't track well: shared accounts. Many tools (analytics dashboards, social media accounts, client portals) don't support individual logins. You share one set of credentials. That's fine operationally — but if you don't record who has access to what during onboarding, you'll be guessing during offboarding. More on this below.

3. Send a Pre-Boarding Email (3 Days Before)

Three days before the start date, send a short email covering: what time to show up (or log on), who to ask for, what to bring or set up in advance, and any reading worth doing before day one. Keep it to five bullet points max — a wall of text before they've started sets the wrong tone.

4. Assign an Onboarding Buddy

Pick one person to be the new hire's first point of contact for two weeks. Not for mentoring — just for answering the small questions people are embarrassed to ask in Slack. A named buddy removes a huge amount of friction from the first few days.

Day One: What Actually Matters

Day one should accomplish exactly three things: make the person feel welcome, get them operational, and give them something real to work on. Everything else is secondary.

The First Hour

Don't schedule a 9am all-hands. Start with a short 1:1 between the new hire and their manager, a quick team intro, and a check that all access is working. If someone spends their first hour waiting for a Slack invite or troubleshooting a broken email setup, the tone for the entire day is off — and first impressions compound.

One Source of Company Context

Give them one place to read about the company — not 12 links to different Notion pages. A single internal wiki or company hub that covers: mission, current priorities, team structure, how decisions get made, and where to find things. If your company docs are scattered across Notion, email threads, and someone's Google Drive, spend 30 minutes consolidating before their start date.

Assign Real Work on Day One

Give them something concrete and completable — even if it's small. Finishing a real task on day one signals they belong and the team trusts them. It doesn't need to be high-stakes; it just needs to be real. A tiny bug fix, a draft social post, a customer call to shadow — anything that produces an actual output.

The First 30 Days: Lightweight Onboarding Track

Beyond day one, the goal is giving the new hire enough context to be effective — without it landing entirely on their manager's plate.

Build a Role-Specific Task Sequence

Write a short sequence of tasks, readings, and check-ins specific to the role. For an engineer: set up the dev environment, read the architecture doc, ship a small fix in the first week. For a designer: review brand guidelines, audit the current product screens, produce a first deliverable. For an ops hire: shadow three customer interactions, document one broken internal process, own one recurring task.

The important thing is that this sequence is written down and assigned — not just described verbally and then forgotten. Role-specific onboarding tracks that auto-assign to every new hire in that role save the most time at 15+ people.

Day 7 Check-In

A short 30-minute conversation at the end of week one, focused on one question: does the person have what they need? Blocked on anything? Confused about anything? This is the cheapest problem-solving conversation you'll ever have — everything is still easy to fix at day 7.

Day 30 Check-In

At the end of month one: are expectations aligned? Is the work making sense? Are there early performance signals — positive or concerning — that need to be named now rather than at a 6-month review? This conversation should be structured (same questions every time) and documented.

The Access List You'll Need at Offboarding

Here's the part most onboarding guides skip: everything you provision during onboarding becomes a liability when the person leaves.

Every tool you grant access to during onboarding needs to be revoked during offboarding. If you don't record what you provisioned — especially shared credentials and tools without individual user seats — you'll be guessing months later. Guessing means things get missed: a former employee still in your GitHub org, still in your analytics dashboard, still on a client Figma file.

The fix: the tool list you build during onboarding is the offboarding checklist. Same document, run in reverse.

For a deeper look at how this works, see our guide on how to revoke employee access automatically and what a complete employee offboarding process looks like.

Optserv handles this by tying access provisioning to the HR record. When you add a new hire and specify their role, the tools they get access to are recorded. When they leave, those same records drive the revocation flow — no guessing, no manual chasing. Start a free trial at app.optserv.ai/signup.

FAQ

Do I need onboarding software at 10 people?

No — a well-structured Notion doc or even a Google Sheet can handle the checklist at 10 people. The value of dedicated tooling comes at 15–20+ hires, when the manual overhead of tracking access and check-ins becomes genuinely painful. The more important thing at 10 people is having a written process at all.

What's the most common onboarding mistake at small startups?

Waiting until day one to provision tool access. By the time the new hire shows up, every invite should already be sent and every account already created. A new hire who spends their first morning waiting on a Slack invite or a GitHub org invite starts their tenure on the wrong foot — and it signals disorganization that's hard to walk back.

How long should onboarding take at a startup?

The active onboarding period — where someone is still getting context, completing training tasks, and having structured check-ins — should run for 30 days minimum. The first 90 days is the full ramp to independent productivity. "Onboarding" isn't over when day one ends.

What tools do I need to track during onboarding for offboarding purposes?

Any tool that doesn't automatically revoke access when you delete a user. That includes: shared credential accounts (analytics, social, client portals), GitHub org membership, Figma org seats, Notion workspace membership, 1Password vaults, and any cloud infrastructure consoles. If you're managing these with remote team tool access management, you need a record at hire time or you'll miss something at departure time.
