Leasing a property sounds simple on paper. A tenant finds a listing, expresses interest, and signs a lease. In practice, the process between interest and signature involves dozens of small but time-consuming steps, most of them handled manually by agents who are already stretched thin across multiple listings and clients. Mustafa Bostanci spent years watching this play out in real property management environments, and what he saw convinced him that the problem was not the people doing the work. It was the absence of a system capable of doing it for them.
That conviction became TenantSider Inc., an AI leasing automation platform Bostanci founded to manage the entire rental workflow from the first tenant inquiry through to lease execution. The company is currently in its pre-launch phase, preparing for initial commercial rollout in California, with a national expansion across the United States planned over the next twelve months.
A Background That Connects the Dots
Bostanci holds a Master of Science in IT Project Management from a U.S. institution, graduating with Magna Cum Laude distinction, along with an undergraduate degree in Information Technology that earned him a High Honor Certificate and two Honor Certificates.
His exposure to real estate came through direct involvement in property management operations, where he observed the same pattern repeating itself. Agents spending hours answering repetitive inquiries. Documents chased through email chains that stalled. Tours coordinated manually when a system could handle it in minutes. Each of these tasks was predictable enough to automate, yet none of them were.
“The tools that existed were built to help people manage information,” Bostanci says. “What was missing was a system that could take that information and actually move the process forward on its own.”
What the Platform Does
TenantSider connects every stage of the leasing workflow into a single automated sequence. When a prospective tenant submits an inquiry, the system responds immediately through AI-powered communication and begins the qualification process. It then coordinates tour scheduling, collects required documents, supports screening workflows, and prepares the lease for execution. Each step flows directly into the next, with the agent entering the picture at the review and decision stage rather than at every point along the way.
One of the platform’s most practical capabilities is automated lease preparation. An agent inputs property details and approves a lease template once within the system. Every time a tenant reaches the lease stage after that, TenantSider generates a pre-filled, agent-approved agreement and delivers it automatically. For professionals managing several properties with regular turnover, this removes one of the most repetitive administrative tasks in leasing without requiring any change to how the agent conducts their business.
The platform also incorporates voice-based communication into the leasing workflow, extending its automation capabilities beyond text-based channels and handling the full range of how prospective tenants typically make first contact.
Beyond Leasing
While the platform automates leasing from inquiry to lease execution, it continues to manage the ongoing rental lifecycle, including payments, maintenance coordination, and communication, turning what is typically a fragmented process into a continuous system.
TenantSider includes built-in rent collection functionality, allowing tenants to make payments directly within the platform, with automated reminders and tracking that reduce manual follow-up for agents and property managers. The system also supports maintenance requests, collecting and evaluating tenant-reported issues, applying AI-assisted pre-intake and prioritization, and routing requests in a structured way before agent intervention.
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. 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.
“We did not want to build a leasing tool that stops working the moment the lease is signed,” Bostanci says. “The relationship between a tenant, an agent, and a landlord continues for months or years after that point. TenantSider is designed to support that entire relationship, not just the transaction that starts it.”
From Testing to Market
Before moving into commercial rollout, Bostanci deployed TenantSider in active property management operations to validate the system under real conditions. The platform was tested in collaboration with a company managing more than 700 units in California, running through live leasing transactions and generating real operational feedback. Qualification logic, document workflows, and scheduling coordination were each refined based on how actual transactions behaved under those conditions.
A joint study by Dr. James Oldroyd at MIT and InsideSales.com found that the odds of qualifying a lead drop 21 times when response time goes from five minutes to thirty minutes, making response speed one of the most critical factors in leasing conversion. In competitive markets where qualified tenants are evaluating multiple properties at once, the speed and consistency of a platform like TenantSider directly affects whether an inquiry becomes a signed lease or a missed opportunity.
The Segment That Gets Left Behind
Enterprise property management software has historically been built for institutional operators with large portfolios and dedicated operations teams. Independent agents and small to mid-sized property management companies have had to make do with tools designed for a different scale of operation entirely. TenantSider addresses a common operational problem across the real estate leasing industry through a system that scales across portfolios of any size. The platform’s SaaS pricing model is designed to remain accessible across different operator sizes, while its architecture scales without requiring a full operations department to run it.
U.S. Census Bureau data shows there are approximately 42.5 million renter households across the United States, with demand sustained by demographic and economic trends that show no sign of reversing. The professionals managing that demand across different segments of the market represent a large and underserved portion of the real estate industry, and Bostanci has positioned TenantSider to address this gap through a system that operates across portfolios of varying size and complexity. This approach reflects Bostanci’s broader view that leasing should operate as a continuous system rather than a series of disconnected tasks handled manually.
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. By consolidating operational and financial data, the platform eliminates the need for manual tracking and separate reporting tools across disconnected platforms.
“We are not building this only for the largest operators in the market,” he says. “We are building it for the professionals doing the most work, who have had the least support from the technology that was supposed to make their jobs easier. That is the problem worth solving.“
