The real estate industry revolves around forms — often handwritten, scanned PDFs that can span hundreds of pages and are time-consuming to manage. That is, until Rexera started building technology to eliminate paperwork friction from homeowners association (HOA) and condo acquisitions. Today, the organization helps 1% of all U.S. residential real estate transactions run risk- and error-free by reducing up to four hours of manual work per transaction.
To do this, Rexera uses AI to tackle tedious, error-prone tasks, letting its customers — title and escrow companies, lenders, and real estate investors — instead focus on closing deals and building relationships. Take HOAs. Typically, you’d have to identify the HOA, gather and confirm information, request payoff letters or statements, ensure compliance, enter data into systems, communicate updates. . . the list goes on.
“With Rexera, this process is transformed thanks to our AI agents and Slack,” said CEO and co-founder Vishrut Malhotra. Customers simply submit an address and due date, and Rexera’s AI agents handle everything automatically. “What once took four hours is completed in seconds with incredible accuracy, eliminating the stress of missed emails, delayed responses, or incomplete documentation. We’re freeing clients from a convoluted coordination process.”
Slack is the linchpin that holds everything and everyone together, enabling seamless operations between the AI agents and Rexera’s teams, who work from Bulgaria, India, and the US. “Slack was the right tool for us to scale with and collaborate in,” said Malhotra. “Without Slack, we wouldn’t be able to do what we do.”
“Buying or selling a home is one of the most significant moments in people’s lives. Delays can disrupt dreams — so speed is everything. Slack is a powerful way for us to collaborate instantly and ensure a smooth and seamless experience for our customers during this critical time.”
Employees and AI working together to deliver an elite client experience
A squad of custom AI agents power Rexera’s platform. AI agents are computer programs that autonomously perform tasks or make decisions, using human-defined rules to govern their behavior. They often consist of multiple large language models (LLMs), each working together to handle specific subtasks to complete the agent’s assignment. Rexera’s agents tackle everything from routine data entry to complex problem-solving, relieving Rexera’s customers from the drudgery of repetitive work.
For example, instead of spending countless hours chasing HOAs, utility companies, and tax authorities for critical information, Rexera’s customers can rely on an AI agent called Florian. Fluent in human-like interactions, Florian makes hundreds of calls each week, obtaining accurate information tirelessly. The work Florian completes frees up Rexera’s customers to focus on higher-value, client-facing activities instead of draining, time-consuming tasks.
Just a handful of Rexera’s additional AI agents include AgentRex, the “web expert” that eliminates the need for manual portal work and can place orders, fill out forms, and extract data across hundreds of sites simultaneously. Then there’s AgentEma, the “communication hub” that acts as a 24/7 email monitoring system, processing and replying to thousands of communications in real time. And AgentMilo, the “report master” that turns raw data into polished reports at scale. These agents allow Rexera’s customers to shift their focus to strategic priorities while AI takes care of the heavy lifting.
Like all technology, the AI agents aren’t perfect. They sometimes fail, and this is where Slack becomes indispensable. When an AI agent encounters an issue that it can’t resolve, it notifies a human-in-the-loop (HITL) and alerts them that intervention is needed to unblock the work it’s doing. This system ensures that even when things go wrong, they don’t stop working. Instead, Slack empowers Rexera’s teams to oversee the health of the AI network, bringing employee oversight into play only when necessary.
For example, one LLM might extract data from an HOA document stating that there are no age restrictions, while another LLM identifies an amendment requiring one resident to be 55 or older. A Slack integration flags this conflicting information and alerts the operation team, who reviews and resolves the issue — sometimes directly in Slack itself.
“This Slack integration not only ensures accuracy but also enhances efficiency, allowing human oversight to step in seamlessly only when needed, without disrupting workflows,” said Malhotra.
“Slack’s role as a centralized operating system and review platform underscores its importance in delivering fast, error-free outcomes in our document-heavy industry.”
Supercharging team and client success with a centralized operating system
Aside from integrations with Rexera’s AI agents, its Slack workspace is set up for seamless communication and efficient workflows. “The ability to organize everything according to how our business functions is unmatched,” said co-founder Anton Tonev.
There are dedicated channels for each team, such as sales, customer success, and marketing, as well as channels designed for specific purposes, like alerts. For instance, when someone visits the company website or fills out a form, a plugin triggers a notification to a Slack channel called #website-visitors, ensuring that everyone who needs that information is in the loop and can follow up with that potential new client.
Beyond this, the company creates a unique Slack channel for almost every client. Here, cross-functional teams, including engineering, product, customer success, and sales, can collaborate on delivering top-tier client service. In some cases, there’s an additional, secure Slack Connect channel shared directly with the client where day-to-day tasks, projects, and technical discussions happen.
“The ability to quickly collaborate on Slack or dive into a client-specific channel to instantly access threads with input from 40 team members is incredibly powerful,” said Tonev.
What makes Rexera’s setup particularly effective are Slack integrations. With HubSpot, for example, sales and customer service teams rely on Slack for real-time updates and insights from all parts of the operation. “Being just a keystroke away from managing deals and tasks with HubSpot in Slack is a game-changer,” said Tonev.
The team also uses huddles as an easy, lightweight way to sync across time zones. “I love when we can be physically together — but that’s not possible when you’re on three different continents. Huddles is the closest thing that comes to that,” said Tonev. “I’m probably in a dozen huddles a day.”
“Slack is our operating system and I don’t know how any team can function without this kind of backbone and infrastructure.”
Redefining real estate, one HOA at a time
Rexera is inspired by customers every day, actively incorporating their feedback to provide a platform that, as it says, “saves the time and nerves of everyday real estate heroes.” Slack helps its team — and in turn, its customers’ real estate closings — move fast. The company is even exploring how it can make the human remediation process as seamless as possible, perhaps even allowing the resolution to occur entirely within Slack. By consolidating all actions in one system, the Rexera team could dramatically reduce the time required to intervene, making for a smoother, more efficient process for employees and customers alike.
For now, Rexera will continue to empower busy professionals to effortlessly manage HOA documentation — without ever interacting with an HOA. “With Slack, we can seamlessly scale from here,” said Malhotra. “We’re just getting started.”
