How Should an AI Company Choose a Commercial Real Estate Broker?

Commercial real estate brokers fall into two camps. Landlord (listing) agents are hired by building owners to fill vacancies, and their job is to get the highest rent and the strongest lease terms for the owner. Tenant representation brokers are hired by the company that needs space, and their job is the opposite: lower total occupancy cost, more flexibility, and fewer obligations for the tenant.

Many large brokerage firms do both, sometimes in the same building. That does not make them bad people, but it does create a structural conflict. If the firm that represents you also leases the building you are touring, it earns more when you pick that building, and it may hold information about the landlord it cannot share with you.

In Illinois, the Real Estate License Act presumes that a licensee working with a consumer is that consumer’s designated agent unless a written agreement between the sponsoring broker and the consumer sets up a different relationship (225 ILCS 454/15-10). A broker can also act as a dual agent, representing both sides, only with the informed written consent of all clients (225 ILCS 454/15-45). The practical takeaway: get the relationship in writing, and read any dual-agency disclosure before you sign it. Have your attorney review the representation agreement.

Ask directly: "Does your firm list or manage any building we might tour?" A tenant-only firm can answer no without qualification.

In a standard office lease, the landlord pays the commission to both the listing agent and the tenant’s broker. The fee is built into the landlord’s leasing budget for the building whether or not you bring a broker, so hiring one does not mean writing a separate check.

Confirm the arrangement in your representation agreement anyway. Some situations are different: certain subleases, very small or short-term deals, purchases, or consulting-only engagements such as a lease audit may be structured another way. A good broker will explain how they are paid on your specific deal before you start touring, and will not steer you toward a space because it pays more.

Plenty of brokers now market themselves to AI companies. The label matters less than whether they understand how a technology tenant actually uses and outgrows space. Look for a broker who can talk specifically about the following:

• Growth risk: structuring expansion rights, rights of first offer on adjacent space, and sublease and assignment language so a lease does not trap you if headcount doubles or a round slips.
• Change of control: making sure a financing, merger, or acquisition does not require landlord consent or trigger a default.
• Infrastructure: server or IDF/MDF rooms, supplemental cooling that runs around the clock, dedicated circuits, generator and riser rights, and carrier options in the building. These are questions to ask the landlord, not assumptions to make from a floor plan.
• Security and access: card access, after-hours entry, and who controls the systems.
• Space type: knowing when a software team needs only office space and when hardware, robotics, or sensor work belongs in flex or light industrial space.
• Venture-backed credit: presenting financials and runway so a landlord is comfortable, and negotiating deposits or letters of credit that burn down over time.

Heavy model training usually runs in a cloud or colocation facility rather than an office. A broker who understands that will keep your office search focused on what your people need day to day, instead of chasing building power the lease will never use.

Listing sites show what landlords choose to advertise. A tenant rep who is active in the market also knows about space coming back from tenants who are downsizing, sublease space that has not been posted yet, and which owners have capital to fund a build-out. For a company that needs to move quickly, that off-market inventory can be the difference between having options and having none.

Market knowledge also covers the landlords themselves: how they approach concessions, how long their approvals take, and how they have treated tenants that grew or shrank mid-lease.

Interview more than one firm. These questions separate a tenant advocate from a generalist:

• ✓Does your firm represent landlords, list buildings, or manage property anywhere in our search area?
• ✓Will you put your role as our agent in a written agreement, and how are you paid on this deal?
• ✓Which technology, software, or data companies have you represented, and can we speak with one?
• ✓How would you structure expansion, contraction, and sublease rights for a company that may double or halve in two years?
• ✓How do you protect us if we raise a round, merge, or get acquired during the lease?
• ✓Who on your team will actually run our search and negotiation day to day?
• ✓How do you create competition between buildings, including on a renewal with our current landlord?
• ✓Can you support locations in other cities if we open a second office?
• ✓What will you need from us, and what does your timeline look like from kickoff to move-in?

Listen for specifics. A broker who answers with examples of lease clauses, tenant improvement negotiations, and how they handled a client that outgrew its space is giving you more than a sales pitch.

Watch for a broker who pushes one building early, discourages you from touring elsewhere, cannot explain who pays them, or treats the letter of intent as a formality. The letter of intent is where most of the economics get set, and the lease is where the flexibility an AI company needs actually lives.

Once you have chosen a broker, a disciplined process looks like this:

1. Write down headcount scenarios, hybrid attendance, must-have infrastructure, and budget before touring.
2. Sign a representation agreement that states the broker works for you.
3. Review a market survey that includes off-market and sublease options.
4. Tour a short list, then send requests for proposals to several landlords at once.
5. Compare proposals on total occupancy cost and flexibility, not just the headline rent.
6. Negotiate the letter of intent, then have your attorney negotiate the lease with your broker alongside.
7. Manage build-out, move timing, and the notice dates for any options you secured.
