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.

Start Free See How It Works

What you get

Space-and-term debate

The Operator and CFO debate 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.

Questions people ask

Real questions. Multiple expert perspectives. Every time.

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

“Sublease vs direct lease vs coworking for 20 people?”

“Landlord is offering 3 months free rent for a 5-year term. Worth the lockup?”

“How much space do I need for a team that will grow 2-3x?”

“Tenant-improvement allowance — how do I evaluate $50/sqft?”

“Should I include a contraction/expansion option even if I have to pay for it?”

Key Recommendations

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
Contraction options cost a small premium but protect against work-model shifts

Synthesized Recommendation

Do not sign the 5-year lease. Sign a 3-year with a 2-year extension option at locked rate; that gets you 80% of the discount without the full lockup. Include a sublease right with landlord approval not unreasonably withheld, and a contraction option at year 2 if your team is more than 30% remote. Take the TI allowance but cap your contribution at $20/sqft.

Watch Out For

TI allowances frequently come with strings — read the recapture clauses
Personal guarantees are common at early stage — limit scope and duration aggressively

Why SynthBoard for this

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.

Common questions

The questions people ask before they sign up.

How much office space do I need?

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 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.
