Built by a broker, for brokers, meet the founder.

I started DealDesk because I was tired of doing the same three things over and over.

First was reading leases. As a working tenant rep, I'd get a 90-page office lease in my inbox and spend 45 minutes pulling out the clauses my client cared about, base rent, TI, escalation cap, restoration obligations, the option to renew at FMR with the appraisal carve-out. Forty-five minutes per lease, ten leases a month, and that was a half-day of my week gone before I touched a real deal.

Second was drafting LOIs. Every counter-LOI was 70% the same template, 30% the deal parameters. I'd retype the same paragraphs about delivery condition, force majeure, and broker commission language for the thousandth time, then drop in the rent and term, then send it. Some of my peers used Word macros. The macros were better than nothing and worse than what was possible.

Third was building tour books. Shortlist five spaces, pull photos, paste in floor plans, format the matrix, ship the PDF. Three to five hours of associate time per shortlist, every shortlist, on every deal.

Why now

I'd been thinking about this for years, but the AI capability that made it actually possible only landed in 2024. Earlier-generation models could not handle commercial leases reliably. I tried. Many people tried. The accuracy on the long-tail clauses was not good enough to deploy.

Claude 3.5 was the first model where the abstraction worked well enough that I could trust it on a real deal. Claude 4 made the LOI drafting work. Claude 4.5/4.6 made the space report builder work. The capability curve was closing in on the work I do, and at some point in 2025 it became obvious that someone was going to build the version of this software that brokers actually wanted, and it might as well be a broker doing the building.

Who DealDesk is for

Tenant reps and landlord reps at firms with 10-200 brokers. Boutiques and the regional offices of the big shops. The brokers who do the work themselves and care more about their per-deal margin than about whether their software vendor sends a sales team to Cannes.

It's not built for institutional capital markets shops, and it's not built for property management. Those are real categories with real software needs that are different from ours. We picked the lane we know, leasing brokerage, and we're staying in it.

What's next

The product is shipping. The team is small and the next hires are an engineer for the comps inventory work and a designer who's worked on dense data UIs (LiveCoaching, Stripe, Linear). If that's you, my email is at the bottom of every page on the site.

If you're a working broker who wants to see whether the abstractor would save you the 45 minutes I used to lose, the free tier is three abstracts a month with no card. Start there. Bring me a hard one.
