Tandem vs Legacy Real Estate Brokers?

Working with a legacy commercial real estate broker — CBRE, JLL, Newmark, Cushman & Wakefield, and so on — typically takes 90 to 180 days to place a startup in a new office, and indexes highly on the listings those firms control. Tandem, an AI-native office leasing brokerage backed by Y Combinator, has placed 500+ companies in offices in an average of 27 days, with access to 30% more spaces than traditional broker networks. If you're a business owner or founder looking for private office space, that gap is worth understanding before you make any calls.

What a Legacy Commercial Real Estate Broker Actually Does

To compare Tandem vs. legacy brokers fairly, you need to understand what the incumbents are built for.

Firms like CBRE, JLL, Newmark, Cushman & Wakefield, and Colliers are full-service commercial real estate firms. Their bread and butter is large enterprise tenants: law firms signing 20,000 sqft for 10 years, financial institutions negotiating entire floors in Class A towers. That's where the commission math works best. A 2,000 sqft startup lease generates a fraction of the fee a Fortune 500 deal does, which means your search often lands with a junior broker, competes for attention against bigger mandates, and moves at whatever pace a firm built for enterprise clients is willing to move.

A few other structural quirks matter for founders:

• Listing control: Legacy brokers earn larger commissions on spaces where they also represent the landlord. That conflict shapes what they show you.
• Relationship silos: Each firm hires brokers as independent contractors. Each broker has their own set of relationships and people that they like to do business with. No single broker sees the whole market.
• No startup specialization: Most traditional brokers don't speak equity, burn rate, or Good Guy Guarantees. They're built for balance sheets and income statements, not venture funding and cap tables.

None of this makes legacy brokers incompetent or unimportant. It can, however, make them misaligned with what an an early-to-mid stage startup actually needs.

How Tandem's Approach Differs From a Traditional Office Broker

Tandem is like an office brokerage on steroids.

Every Tandem agent is backed by an agentic brain that knows the whole market: what's available, what asking rates are, what other deals closed for in the building, which spaces are about to come to market, and what landlords are likely to give the most. Tandem's AI lets everyone work with a best-in-class broker, regardless of the size of office you're looking for.

Tandem aggregates supply across three space types — private leases, shared spaces, and subleases — and layers in AI market intelligence to surface options that match your actual requirements: headcount, budget in $/sqft/year, neighborhood preference, and lease-length flexibility.

Here's what that looks like in practice:

30%+ more inventory. Tandem has built direct relationships with landlords, host companies offering shared space, and sublessors across NYC, San Francisco, and Boston. That means it surfaces options that never appear in any single traditional broker's pipeline. You're not limited to one firm's portfolio.

27-day average placement. The industry average for an office lease runs 90–180 days through a legacy firm. Tandem's process — from first tour to signed agreement — averages 27 days. That matters when you've just raised a Series A and need to stop working out of a WeWork before your new engineers show up on day one.

Free to you. Like traditional brokers, Tandem is compensated by the landlord or host company.

Startup-native expertise. Tandem advisors have worked with dozens of startups, including Cursor, Upwork, Volta, and countless others. For a deeper walkthrough of the leasing process, see our guide for how to rent office space as a startup.

What Types of Office Space Can You Find Through Tandem vs. a Traditional Broker?

Legacy brokers focus almost exclusively on direct leases — you signing with a landlord for a fixed term. That's the right product for some startups. But it's not the only product, and traditional firms rarely give you a clean comparison across all three options.

Tandem surfaces all three space types in a single search:

A traditional broker will almost never show you a shared space — there's no landlord commission to collect. Tandem shows you all three because the goal is finding the right space for your team's stage and risk tolerance, not maximizing transaction size.

For a seed-stage team of 8 moving into their first real office, a shared space in Flatiron or SoMa might be the right call. For a 25-person Series B team that needs its own identity, a private lease in NoMad or SoHo makes more sense.

How AI Market Intelligence Changes the Office Search

Traditional brokerage is relationship-driven and opaque. A broker knows what their colleagues have toured recently, which landlords are flexible on terms, and which buildings have ghost listings sitting vacant. That institutional knowledge is valuable — but it's tribal, slow to update, and not shared with you in any systematic way.

Tandem's AI-powered leasing layer does something different: it aggregates market data across available inventory, pricing signals, neighborhood trends, and comparable lease economics to surface recommendations matched to your actual inputs — not the broker's existing relationships or commission priorities.

Practically, this means:

• You see more options, faster, ranked by fit rather than by who the broker knows
• Pricing is transparent: if private offices in the Mission are running $45–$65/sqft/year, you see that before you make an offer
• Historical lease velocity data shows how quickly spaces in a given neighborhood move — useful when you're deciding whether to jump on a Tribeca loft or wait on a second option in Chelsea

The Tandem Process vs. Working With CBRE, JLL, or Newmark

Here's what a typical startup office search actually looks like through each path.

The traditional broker process

1. You call a firm, get assigned to a broker (often junior)
2. Broker runs a needs assessment, shares a PDF of available listings — their listings
3. Multiple tours scheduled over 3–6 weeks
4. You choose a space, broker drafts an LOI
5. Landlord counters; negotiation runs 2–6 weeks
6. Lease drafts exchanged; attorney review (your cost) adds more time
7. Total timeline: 90–180 days, sometimes longer

The Tandem process

1. You browse available spaces directly on Tandem or connect with a Tandem agent
2. Tandem surfaces matched options instantaneously from the entire market's availability
3. Curated tours scheduled quickly — typically within the first 24-72 hours
4. Tandem handles LOI drafting and negotiation coordination on your behalf
5. You sign directly with the landlord or host company
6. Total timeline: average 27 days

The Real Cost Differences Between Tandem and a Legacy Broker

The commission structure looks similar on the surface — both are paid by the landlord, not by you. But the economics diverge in a few meaningful ways.

Negotiation outcomes. Legacy brokers sometimes have dual representation conflicts, working both sides of the same transaction. Tandem represents you exclusively, which tends to produce better lease terms, lower deposits, and more landlord concessions.

Hidden cost exposure. Founders using traditional brokers often discover mid-lease that HVAC overtime fees, after-hours access charges, or TI allowance shortfalls were never flagged upfront. Tandem's diligence process surfaces these before you sign.

Opportunity cost. A 150-day search instead of a 27-day search isn't just slower — it's a distraction from building your company. For early-stage teams, that's real money.
