Klosed is an AI-powered lead reactivation platform built specifically for real estate agents. It automatically texts the dormant leads in your database โ€” past clients, expired inquiries, open-house signups, cold portal leads โ€” in your voice, qualifies replies with natural conversations, and hands warm buyers and sellers back to you ready to work.

What it does: - Automates SMS reactivation across your entire dormant database - Handles objections (rate concerns, timing hesitations) with natural back-and-forth - Qualifies replies to identify serious buyers and sellers - Routes warm conversations back to you in real time with full context - TCPA-compliant with automatic opt-out handling - Runs 24/7 without recruiting, training, or managing a person

Who it's for: Solo real estate agents and small teams (1-5 agents) with 500+ dormant leads sitting in a CRM. Especially valuable for agents who have databases of past clients, expired inquiries, or old portal leads they've stopped following up with.

Pricing: Flat $299/month per agent. No setup fee. 14-day free trial with no credit card required.

Used by agents at: SERHANT Beverly Hills, RE/MAX Advantage, and other brokerages.

Founded and operated by Logan Bates, solo founder.

Node.js features and specs

  • Asynchronous and Event-Driven
    Node.js uses an asynchronous, non-blocking, and event-driven I/O model, making it efficient and scalable for handling multiple simultaneous connections.
  • JavaScript Everywhere
    Developers can use JavaScript for both client-side and server-side programming, providing a unified language environment and better synergy between front-end and back-end development.
  • Large Community and NPM
    Node.js has a vibrant community and a rich ecosystem with the Node Package Manager (NPM), which offers thousands of open-source libraries and tools that can be integrated easily into projects.
  • High Performance
    Built on the V8 JavaScript engine from Google, Node.js translates JavaScript directly into native machine code, which increases performance and speed.
  • Scalability
    Designed with microservices and scalability in mind, Node.js enables easy horizontal scaling across multiple servers.
  • JSON Support
    Node.js seamlessly handles JSON, which is a common format for API responses, making it an excellent choice for building RESTful APIs and data-intensive real-time applications.

Possible disadvantages of Node.js

  • Callback Hell
    The reliance on callbacks to manage asynchronous operations can lead to deeply nested and difficult-to-read code, commonly referred to as 'Callback Hell'.
  • Not Suitable for CPU-Intensive Tasks
    Node.js is optimized for I/O operations and can become inefficient for CPU-intensive tasks, slowing down overall performance due to its single-threaded event loop.
  • Immaturity of Tools
    Compared to more established technologies, some Node.js libraries and tools still lack maturity and comprehensive documentation, which can be challenging for developers.
  • Callback and Promise Overheads
    Managing asynchronous operations using callbacks or promises can lead to additional complexity and overhead, impacting maintainability and performance if not handled correctly.
  • Fragmented Ecosystem
    The fast-paced evolution of Node.js and its ecosystem can lead to fragmentation, with numerous versions and libraries that may not always be compatible with each other.
  • Security Issues
    The extensive use of third-party libraries via NPM can introduce security vulnerabilities if not properly managed and updated, making applications more susceptible to attacks.

Klosed features and specs

  • Automated SMS Reactivation
    Automatically texts dormant leads in your database using AI-generated messages that match your voice.
  • Natural Conversation AI
    Handles two-way conversations, objections (rates, timing), and qualifying questions like a real ISA would.
  • Warm Lead Handoff
    Routes qualified buyers and sellers back to you in real time with full conversation context.
  • TCPA-Compliant Texting
    Automatic opt-out handling, STOP recognition, and time-of-day restrictions built into every message.
  • CSV Upload โ€” No CRM Integration Required
    Upload your dormant leads directly from any CRM export. Works with Follow Up Boss, kvCORE, Lofty, Sierra, and any spreadsheet.
  • Flat Pricing, No Setup Fee
    $299/month per agent. 14-day free trial with no credit card required.

Questions & Answers

As answered by people managing Node.js and Klosed.

What makes your product unique?

Klosed's answer:

Klosed is the only AI reactivation tool built specifically for solo agents and small teams, with flat SaaS pricing and self-serve setup. Most tools in the space are either bespoke enterprise services (Pura Vida Data), full-service ISA replacement platforms (RealEstateISA, Structurely), or CRMs that add AI as a feature (Follow Up Boss, kvCORE). Klosed does one thing exceptionally well: reactivating dormant leads via SMS, in the agent's voice, with automatic qualification and warm-lead handoff. Predictable $299/month, no setup fee, no long-term contract.

Why should a person choose your product over its competitors?

Klosed's answer:

Three reasons. First, transparent pricing โ€” flat $299/month per agent vs. competitors that charge $500-$2,500/month with setup fees and long-term contracts. Second, purpose-built focus โ€” Klosed is optimized for dormant lead reactivation specifically, not enterprise ISA replacement or full-funnel CRM. Third, real proof โ€” used by agents at SERHANT Beverly Hills and RE/MAX, with real conversation screenshots showing reactivation on year-cold leads, including a $2.5M Malibu buyer surfaced from dormant SERHANT leads.

How would you describe the primary audience of your product?

Klosed's answer:

Solo real estate agents and small teams (1-5 agents) with 500+ dormant leads sitting in their CRM. Especially valuable for agents with databases of past clients, expired inquiries, open-house signups, or old portal leads (Zillow, Realtor.com, Facebook) that they've stopped following up with. Ideal customer: an established agent with 3+ years of business who has thousands of contacts but no time to work them manually.

What's the story behind your product?

Klosed's answer:

Klosed was founded by Logan Bates, an 18-year-old solo founder who went full-time on the project in 2026. The idea came from watching agents systematically ignore the leads they'd already paid to acquire while spending thousands more on new leads that convert at 1-2%. The first proof point came from manually running the reactivation playbook on a (SERHANT Beverly Hills) agent's dormant database โ€” surfacing a $2.5M Malibu buyer and multiple qualified sellers within weeks. That validated the wedge: agents don't need more leads, they need to work the ones they have.
