Walk through any property management office in the United States and you will find the same scene. Multiple browser tabs open. Emails waiting. A leasing agent on the phone scheduling a tour they will later need to manually add to a calendar, confirm with the tenant, and follow up on afterward.
U.S. Census Bureau data shows there are approximately 42.5 million renter households across the United States, yet the operational workflows supporting most of that demand have remained largely unchanged.
TenantSider was built on the premise that this does not have to be the case. Founded by Mustafa Bostanci, the platform automates the entire rental operations workflow inside one connected system, from the first tenant inquiry through to lease execution, ongoing payments, and maintenance coordination, without requiring a property manager or agent to manually handle each step.
A Different Way of Thinking About Leasing Software
Most property management platforms are organized around information. They store tenant records, document communication histories, and archive lease files. What they do not do is take action on that information. The follow-up email still needs a human to send it. The tour still needs a human to schedule it. The lease still needs a human to prepare it.
TenantSider approaches the problem differently. When a prospective tenant submits an inquiry, the system responds immediately and moves through qualification, tour scheduling, document collection, and lease preparation automatically, with the agent stepping in only at the review stage. Lease preparation runs through a pre-approved template, so every subsequent agreement is generated and routed for signature without any repeated manual work.
A Full Operational System
Rather than serving a single user type, TenantSider connects tenants, agents, and property owners within a unified operational system, allowing the full rental lifecycle to be managed in one place. The platform includes built-in rent collection, allowing tenants to make payments directly within the system, with automated reminders and tracking that reduce manual follow-up. Maintenance requests are handled through AI-assisted pre-intake and prioritization, collecting and evaluating tenant-reported issues and routing them in a structured way before agent intervention.
Property owners are given access to a dedicated dashboard where they can track leasing activity, tenant status, and rent collection, providing visibility into operations without relying on manual updates from their management team. TenantSider also provides integrated financial and performance analytics, allowing agents and property managers to track rental income, occupancy and vacancy rates, and overall portfolio growth through a single system.
“The rental relationship does not end when the lease is signed,” Bostanci says. “TenantSider is designed to manage the entire lifecycle, from the first inquiry to the last rent payment, inside one system.”
Tested Where It Matters
Before going to market, Bostanci deployed TenantSider with a property management company managing more than 700 units in California, testing the platform under live leasing conditions and refining it based on real operational feedback. That process shaped the final product in ways that internal development could not have replicated.
“You only learn what actually needs to work by running the system in the environment it was built for,” Bostanci says. “That testing phase was not optional. It was the whole point.”
TenantSider is now moving into broader commercial rollout in California, with a national expansion planned over the next twelve months. The platform is delivered as a SaaS subscription designed for independent agents and all sizes of property management companies looking for automation at a scale that fits their operation.
