See the full picture across your rental portfolio.

Every maintenance request, vendor invoice, and lease update is a data point about your rental properties. The average portfolio generates ~94 emails per property per year. They often have many of the same issues, water heater needs to be replaced, make-ready expenses, so it becomes hard to keep the details straight by just reading emails. We had that problem ourselves, which is why we built The Control Surface, to assemble all the emails into logical cases, timelines, and cost records so the full picture is always there when you need it.

Tax season arrives

You need repair costs and vendor payments, but they're buried across hundreds of emails.

A repair request gets buried

Your property manager sent an update three weeks ago. You read it. But the follow-up never came, and you didn't notice.

A partner asks questions

"How much did we spend on that roof?" You know the answer is somewhere in your inbox.

You're switching property management companies

You need the full history before the transition: every vendor, every open item, every cost.

Frequently asked questions

What email data does The Control Surface access?+
The Control Surface requests read-only access to your Google email (Gmail or Google Workspace). During the initial discovery scan, we scan only metadata (sender and subject lines). For imported properties, we use AI to read and summarize email content to extract maintenance details, costs, and vendor information. We never access emails unrelated to your confirmed properties.
Can I revoke The Control Surface's access to my Gmail?+
Absolutely. Visit Google Security Settings (myaccount.google.com/security) and remove The Control Surface from your connected apps. You can also delete your The Control Surface account from your dashboard settings, which removes all stored data and immediately revokes our access to your Gmail account.
How does the AI extract information from emails?+
Google's Gemini AI reads each email and extracts structured data: maintenance type, cost estimates, vendor names, dates, and resolution status. The AI understands property management context, distinguishing between "quote for $500" versus "invoice for $500 paid."
How are emails grouped into cases?+
The Control Surface connects the dots between related emails automatically. When the same vendor handles a repair from initial request through completion and invoice, those emails become one unified case. You see the full story - not scattered fragments - so you can track what happened, who did it, and what it cost.
How much does The Control Surface cost?+
Four tiers designed for rental property investors of all sizes: The Scout (free, 1 property) lets you validate the product.
