How Do You Split Territories When You Hire a Second AE?

How do you split territories when you hire a second AE?

Split by the dimension that best predicts how deals are won, usually segment or vertical, then balance the two books by realistic pipeline potential rather than account count. Keep existing open deals with whoever owns them today. Write the rules down, route new leads by those same rules, and review the split after one full quarter.

The second AE hire is where many young sales teams first feel the need for territory rules. With one rep, every lead goes to the same person and nobody argues. With two, every lead becomes a small decision, and small decisions made inconsistently turn into resentment fast.

The goal is not a perfect split. It is a fair, written split that both reps understand, that your routing can enforce automatically, and that you are willing to revisit with data.

Why does a second AE need a territory at all?

Without one, two reps compete for the same inbound leads and the same target accounts. That creates double outreach to prospects, arguments over credit, and a manager stuck refereeing. A territory gives each rep a clear patch to own and lets them plan account work without worrying the other rep will get there first.

It also protects the buyer. Nothing makes a small company look disorganized faster than two reps emailing the same person in the same week. Clear ownership in your CRM prevents that.

And it makes performance readable. When each rep owns a defined set of accounts, you can compare their results against the potential in their book. Without territories, a rep who happens to catch better inbound leads looks like a better seller, even if they are not.

Which dimension should you split on?

Pick the dimension where deals behave differently. If enterprise and mid-market deals need different skills and cycles, split by company size. If two industries buy for different reasons, split by vertical. Geography makes sense mainly when time zones or languages matter. Splitting alphabetically or randomly is simple, but it teaches neither rep anything.

Your closed-won and closed-lost data will tell you which dimension matters. Look at deal size, cycle length, and win rate by segment, industry, and region. Where the differences are largest, that is your split. Where they are small, the dimension does not matter much for territory design.

For most early-stage B2B teams I work with, the honest answer is company size or vertical. Geography often looks tidy on a map but ignores how deals actually get won, especially when both reps sell remotely to the same markets.

How do you balance the two books fairly?

Balance by potential, not by count. A book of 300 small accounts and a book of 60 large accounts can be equally fair if their likely pipeline is similar. Estimate potential using account fit, deal size history, and any signals you track, then adjust the boundaries until the two books look comparable.

A simple method works for small teams. Pull your target accounts into Google Sheets, give each one a rough fit tier based on your ideal customer profile, and assign an expected deal value by tier. Sum the expected value for each proposed book. Move boundary accounts until the sums are close.

Do not chase precision. The numbers are estimates, and the first split will be wrong in ways you cannot see yet. Close enough, written down, and reviewed in a quarter beats perfect and endlessly debated.

What happens to the deals the first AE already has open?

The first AE keeps them. Moving open deals to a new rep breaks relationships with buyers mid-conversation and punishes the person who built that pipeline. Apply the new territory only to new leads and untouched accounts. Over a few months, the books naturally converge on the new boundaries as old deals close.

The exception is accounts with no recent activity. If the first AE owns accounts they have not worked in months, those can move to the new rep as part of the initial book. Agree on the inactivity threshold up front so it does not feel arbitrary.

If the founder has been selling too, the same logic applies to founder-owned deals. My notes on handing off a founder-led deal to your first AE cover how to transfer those relationships without losing the buyer's trust.

How should inbound leads be routed between two reps?

Route inbound leads by the same rule that defines the territory, automatically, at the moment the lead arrives. If the split is by company size, the routing reads employee count and assigns accordingly. Leads that do not match any rule should go to a fallback owner who reviews them daily, not into a shared pool.

In HubSpot or Salesforce, this is a routing workflow based on company properties. The properties need to be filled in reliably at the moment of routing, which usually means an enrichment step from a tool like Clay or Apollo before assignment. If the data is missing, the rule cannot fire.

I wrote a step-by-step guide on setting up lead routing by territory in HubSpot, and it applies directly here. The important part is that the routing logic and the written territory rules say exactly the same thing.

What should the written territory rules include?

A one-page document with the split dimension, the exact boundaries, who owns what, how ties and edge cases are handled, what happens to open deals, and when the split will be reviewed. Both reps should read and agree to it before the new hire starts working leads. A rule nobody wrote down is a future argument.

Edge cases deserve the most space. What happens when a company in one rep's segment has a subsidiary in the other? What about a lead that comes in through a partner? What if a contact changes companies? Answer these in writing, even briefly, so the first dispute has a reference.

Also define account ownership versus contact ownership. In most B2B sales, the account should have one owner, and all contacts at that account follow. That prevents two reps from working different people at the same company.

How do you know if the split is working?

After one full quarter, compare pipeline created, meetings booked, and win rate per rep against the potential you estimated for each book. If one book is consistently producing far more opportunity, adjust the boundary. If results differ but potential looked equal, the gap may be about the rep rather than the territory.

Look at activity too. If one rep is running out of accounts to work, their book is too small. If one rep cannot get through their accounts, it is too big. Both are fixable by moving the boundary slightly.

Tell both reps in advance that the first review may change their territory. When that expectation is set early, a change feels like a planned adjustment rather than a punishment.

What mistakes should you avoid with a two-rep split?

Avoid giving the new rep the leftover accounts nobody wanted. Avoid splitting so finely that reps cannot build momentum in a niche. And avoid changing the rules mid-quarter without a clear reason. Each of these erodes trust between reps faster than any compensation detail, and trust between two reps is everything on a small team.

The leftover problem is the most common. It feels natural to let the first rep keep the best accounts, but a new rep with a weak book will struggle, and you will wrongly conclude the hire was bad. Give the new rep a book they can actually succeed in.

If you are also setting the new rep's target, the territory and the quota should be designed together. My guide on setting a quota for your first sales hire explains how to tie the number to the book's real potential.

What should you do next?

Pull your last year of closed deals and look for the dimension where win rate, cycle, or deal size differs most. Draft a split on that dimension, balance the two books by estimated potential, and write a one-page rules document. Set up routing to match it, then put a review date on the calendar.

A fair territory is less about the boundary you draw and more about the clarity around it. Two reps who understand the rules will work together. Two reps who guess will compete.
