Cosmo answers missed calls and messages in seconds, follows up with interested renters until the tour is booked, and keeps tenant requests from getting buried. Built by two LA real estate agents for property owners and managers. Pay once for setup, then choose how much help you want.
Illustrative example conversation
We've heard the same frustrations from owners across Los Angeles for years. They usually aren't about the property. They're about the messages, calls and requests that nobody answers in time.
Finding tenants has gotten harder, and the leasing process is rarely streamlined. A prospective tenant calls or messages about your unit. Nobody gets back to them quickly, so they rent somewhere else.
The cost: you lose a good tenant and the rent the unit could have been earning, one empty day at a time.
Owners tell us the same things about their property managers, again and again:
We've each spent about a decade in commercial real estate, working directly with property owners across Los Angeles.
Sitting across from owners, we kept hearing the same stories: property managers who didn't call back, tenants left waiting on repairs, units that sat empty because nobody followed up. And when owners tried to manage on their own, we saw how much of their time it swallowed.
None of these were unsolvable problems. They were systems problems: communication that depended on someone remembering to reply. Better systems, clearer communication and the right technology could fix most of them. So we built Cosmo to do exactly that, for owners and for the property managers who serve them.
The founders of Cosmo
We set up the systems around the way you already work, including the property management software you use today. Then you decide how much of it we keep running.
No new software for you to learn. We set it up, write the scripts with you, and make sure it works before it goes live.
Cosmo's systems are shaped by years of conversations with Los Angeles property owners about what goes wrong, and what they wish their managers did differently.
Both founders have spent roughly ten years each in commercial real estate in Los Angeles.
As agents, we heard firsthand what frustrates owners about property management, and what makes self-managing so hard.
Response time, tours booked and days vacant. Not clicks, not jargon.
We're in LA. When you need us, you talk to a person who knows your properties.
Move the sliders. Daily cost = monthly rent × 12 ÷ 365.
An estimate for illustration only. At about $2,800/month, a vacant LA unit loses roughly $90 a day.
Our assistant tells people it's an AI, asks everyone the same questions, and never screens or turns anyone away. Your team makes every decision. Calls announce recording, and texts include “Reply STOP.”
We check in with every client about their experience: whether communication improved, whether things got more efficient, and how much time they saved. We only share feedback or results publicly with your permission.
Some owners want us to set things up and hand over the keys. Others want us to keep everything running. You can choose either, and change your mind later.
We review how calls, messages, requests and listings are handled today, then set up your phone line, text-back, assistant scripts, tour booking, request tracking and listings. We test everything with you before it goes live.
Step 2 · Choose what happens next
We set it up, you run it. Everything is built on your own systems and accounts, and we hand you a step-by-step guide so you can run it with confidence.
We keep everything running, review the assistant's conversations, and send you a monthly report.
For owners and managers who want more: listings and tour videos, ads, reviews, inbox digest and reporting.
No long-term lock-in. Monthly pricing depends on your properties and the services you choose. We'll walk you through it before you commit to anything.
Property owners in the Los Angeles area, whether you self-manage or work with a property manager, and the property management companies that serve them.
No. Cosmo works alongside AppFolio, Buildium and similar tools. If your software already posts your listings, we improve what goes out rather than replacing anything.
A review of how calls, messages, maintenance requests and listings are handled today, then your phone line and text-back, assistant scripts, tour booking, request tracking and listing updates. We test everything with you before anything goes live.
Yes, that's what Option A is for. Everything is built on your own systems and accounts, and you pay your tool costs (like your phone and texting service) directly. We walk your team through it and hand you a step-by-step PDF guide for managing each program, so you won't need us afterward. If you ever want help again, you can switch to month-to-month or an ongoing plan.
No. Month-to-month means exactly that: you can change plans or stop any month.
It answers only from the property details you approve and passes anything else to a person. We review its conversations closely in the first weeks so issues get caught early.
Yes. It introduces itself as an AI assistant, announces call recording, and only calls back people who contacted you first. Texts include “Reply STOP” to opt out.
No. We make sure maintenance requests are logged, routed to the right person, and followed up, and that emergencies reach your on-call contact right away. Your vendors still do the work.
Sign up within the next two months and we'll take 30% off your one-time setup fee.
