AI for Lease Decisions

Office leases are long, expensive, and surprisingly hard to exit. Run yours through a CFO, an Operator, a Strategist, a Lawyer, and a Skeptic — and avoid the 5-year mistake.

In short

For startups, plan for the team you'll have in year 2, not year 5 — usually 80-120 sqft per person depending on density and meeting-room needs. The Operator will calibrate against your specific situation and work model.

How a board takes a call like this: her read, who sits, what they ask first, then the call — with how sure they are, who disagreed and the first step.

Lease

Example · Board of 3

Should I sign a 5-year office lease at this stage or sublet flexibly?

Chief of staff

This one needs a board: The CFO, The Operator and The Strategist. The CFO pressure-tests unit economics, runway, and capital allocation. Each researches alone first, then they react to one another — and on a decision, two of them take opposed sides.

The board’s call

Do not sign the 5-year lease.

3-year leases with extensions match growth uncertainty better than 5-year locks. Sublease rights are the most-underweighted clause in early-stage office leases.

Confidence64 · Moderate

The Strategist disagreed

“TI allowances frequently come with strings — read the recapture clauses”

Other asks people bring here

Several asks in one message become several rooms, each with its expert and its own price on the card. Keep or drop any, then convene them together.

Sublease vs direct lease vs coworking for 20 people? — The Operator, up to 85 credits
Landlord is offering 3 months free rent for a 5-year term. Worth the lockup? — The Strategist, up to 85 credits
How much space do I need for a team that will grow 2-3x? — The Lawyer, up to 85 credits

What you get

What she handles.
On this kind of call.

Space and term

The Operator and the CFO weigh how much space, for how long, given your hiring trajectory and remote policy.

Total-cost modeling

The CFO models rent + buildout + utilities + escalation + exit penalties as one number.

Term + exit-clause design

The Lawyer pushes back on the landlord-favorable clauses most leases hide.

Optionality reading

The Strategist weighs sublease rights, expansion options, and exit triggers — usually the variable that determines whether the lease is a tax or a tool.

Why SynthBoard

Why SynthBoard for this.
Not one voice. A board.

Real total cost

The CFO models the full lease cost across all years, including escalation and exit — most leases look cheaper at headline price than they are.

Tenant-favorable clauses

The Lawyer flags landlord-favorable terms (personal guarantees, recapture, exclusive use) most non-real-estate founders miss.

Optionality designed in

The Strategist forces expansion, contraction, and sublease rights into the negotiation, not as afterthoughts.

Anti-aspirational

The Skeptic blocks signing for the team you imagine instead of the team you have.

Who sits

The experts for this call.
Each one holds a position.

Your Chief of Staff proposes who sits for the call, and every board is built with someone whose job is to argue against the obvious answer. Name an expert and they take a seat; tell her who you want on your board and they sit by default. How many seats a board has depends on your plan.

Questions

Fair questions.
Straight answers.

What people ask before they bring this call to a board.

How much office space do I need?

How long should the lease term be?

Shorter than landlords prefer. 3-year terms with extension options match startup uncertainty; 5+ year terms make sense only at later stage or for unique build-out value. The Boardroom will pressure-test for your stage.

What's the most-overlooked clause in office leases?

Sublease rights with reasonable landlord approval standards. Without them, you have no flexibility if the team's shape changes. The Lawyer will insist on them in any lease over 12 months.

Should I negotiate a personal guarantee?

Always try to avoid; if required, cap the amount (often 6 months rent) and the duration (often 24-36 months, declining over time). The Lawyer will design specific language to push back.

What about coworking instead of a lease?

For teams under 15 people, coworking often wins on flexibility and total cost. The Operator and CFO will pressure-test for your specific case.

Can the panel review actual lease terms?

Yes — paste the key clauses and the panel will flag what to push back on. Not a substitute for tenant-rep counsel, but a useful first pass before incurring billable hours.
