Top 3 CRM Competitors of Rethink by Buildout in 2026: AscendixRE, RealNex, and ClientLook

Within the last several years, Buildout has acquired both Apto and Rethink CRM. While Apto was completely downshifted, Rethink was introduced as a core CRM solution – Rethink by Buildout.

Buildout has evolved into a portfolio of separate products rather than a single, unified platform. Today, teams typically use Rethink for CRM, Showcase for marketing and listings, ProspectNow for property intelligence, and Manage & Close for commissions and deal workflows. While these tools integrate with one another, they were built by different companies at different points in time and continue to operate as distinct applications with separate subscriptions.

For many teams, this creates a practical challenge.

As brokerages scale, introduce new service lines, or look for tighter operational alignment, these structural realities often prompt a broader question: Is a multi-product stack still the best long-term fit, or would a more unified CRM platform be easier to manage and scale?

That question is what led us to create this comparison. Below, we look at how Rethink by Buildout compares with three leading alternatives:

• AscendixRE CRM
• RealNex
• ClientLook

In this blog article, we provide an overview of the features and pricing plans for each of these Buildout alternatives to help you make an informed decision for your business.

Top 3 Rethink by Buildout Alternatives

AscendixRE CRM: Designed for Teams That Need Flexibility and Long-Term Scale

AscendixRE CRM is a customizable Salesforce-based CRM solution for commercial real estate. In addition to industry-specific CRM functionality (e.g., commission calculation, stacking plan module), the platform offers 2 added modules:

• Ascendix Search – an advanced searching & filtering tool for Salesforce data, that includes many custom filters (e.g. radius search, search by zip code, etc.), Salesforce geo mapping, related lists, and more.
• Composer – a powerful publishing tool enabling your users to generate professional quality brochures, flyers, property tour books, lease comp reports, sale comp reports, and owner reports for listings.

Being a Salesforce-based CRM, AscendixRE helps commercial real estate brokers and brokerage teams:

• Manage complex relationships and deal structures across contacts, companies, properties, deals, and capital sources without duplicating data or breaking reporting.
• Support multiple business lines in one system, such as brokerage, capital markets, tenant representation, and asset management, while keeping data connected.
• Automate workflows and reduce manual work, from pipeline updates to approvals, commissions, and document processes.
• Gain clearer visibility into performance, using advanced dashboards and reporting that reflect how leadership actually evaluates deals, pipelines, and revenue.
• Adapt the CRM as the business evolves, with custom workflows, data models, and integrations supported by an in-house support and development team.

This becomes especially important for firms managing multiple business lines, sophisticated pipelines, or capital markets activity. Instead of stitching together multiple systems, teams can manage CRM, commissions, capture LoopNet/CREXi inbound inquiries, capital markets, mapping, and document workflows within a single platform.

Another key distinction is support. AscendixRE is backed by an in-house support and custom development team, which means brokerages aren’t limited to out-of-the-box functionality. When workflows change or new requirements emerge, the platform can be adapted without relying on third-party consultants or external integrations.

AI functionality becomes an integral part of AscendixRE CRM in the form of the upcoming functionality – AI Assistant. The functionality aims to eliminate manual CRM data input by leveraging natural voice commands. Users will need just to talk CRM instead of typing. AI Assistant in AscendixRE will assist users in capturing notes, creating records, and searching the database using natural voice commands.

RealNex CRM: A Middle Ground Between Structure and Flexibility

RealNex is another alternative solution to Rethink by Buildout. The company’s products are meant to handle the entire CRE lifecycle, from business development to transaction management.

RealNex offers clients 1 core solution – RealNex Navigator and 4 products: CRM, Transaction Manager, MarketEdge, MarketPlace. Whereas RealNex Navigator includes all the listed solutions, these can be purchased separately as well.

Being a cloud-based CRM, RealNex helps commercial real estate brokers to:

• analyze lease offers
• create branded collateral for their properties
• tie together contacts, companies, properties, spaces, and comps on dashboards
• execute more transactions
• streamline deal management.

RealNex offers multiple integrations, including mobile-ready apps and virtual reality touring via a plug-and-play customization interface.

RealNex positions itself between lightweight CRMs and fully customizable platforms. It combines traditional CRM functionality with transaction management and market tools, offering a more rounded solution than basic contact-centric systems.

For many mid-size brokerages, this balance works well. RealNex provides enough structure to support deal execution while still offering some modularity as needs grow. Teams that want CRM and transaction tools under one vendor, without moving to a Salesforce-based platform, often see RealNex as a practical option.

Where RealNex can fall short is in deep customization. Reporting and workflows are more flexible than entry-level CRMs, but they don’t match the adaptability of platforms built on Salesforce. For teams with highly specific processes, this can become a limiting factor over time.

ClientLook CRM: Simplicity for Smaller Teams

ClientLook, acquired by LightBox, is the commercial real estate CRM software for brokers, investors, and owners. It combines contact tracking, pipeline management, transactions management, and a client collaboration portal with property and listing management.

ClientLook is designed with simplicity in mind. Its strength lies in providing core CRM functionality without overwhelming users with configuration options or administrative overhead.

Smaller teams and individual brokers often appreciate how quickly ClientLook can be implemented and adopted. The interface is straightforward, and collaboration tools make it easy to share information across a small group.

However, ClientLook is not built for scale. As teams grow, reporting needs become more complex, or processes diverge across groups, its limitations become more apparent. For that reason, it’s best viewed as a short- to mid-term solution for smaller organizations rather than a long-term platform for expanding brokerages.

Pricing Comparison

For most brokerages, there are two key pricing questions: “Which CRM is cheapest?” and “Which pricing model aligns best with how our team will operate and grow?” Comparing licensing structure, scalability, and what’s included helps to make a clearer long-term decision.

Rethink is priced as part of the broader Buildout ecosystem. While the CRM itself is licensed separately, most teams use it alongside other Buildout products, such as marketing, property intelligence, or commission management. As a result, the total cost tends to increase as additional modules and user types are added. For firms already invested in Buildout, this can feel incremental; for growing teams, it can become harder to forecast as needs expand.

AscendixRE typically follows a more platform-based pricing model. Because it is built on Salesforce and includes multiple CRE-specific modules within one environment, pricing often reflects a broader operational scope rather than individual point tools. While the upfront investment can be higher than lightweight CRMs, teams often find that total cost of ownership is easier to manage over time — especially when factoring in reduced tool sprawl, built-in capabilities, and access to in-house support and custom development.

RealNex and ClientLook generally sit at a lower entry point. Their pricing models tend to be more straightforward, making them attractive for smaller teams or firms with well-defined, standardized workflows. However, costs can rise as additional modules, users, or integrations are required, and some teams eventually outgrow the functionality provided at those tiers.

Picking the Best Rethink CRM by Buildout Alternative

CRM consolidation and rebranding are constant these days and require vigilance on the part of the broker to assess which product/platform is best aligned with their ongoing requirement set.

While assessing alternatives to Rethink CRM by Buildout for your business, here are some best practices and key evaluation criteria to consider:

• Less is more – the tool with the most “bells and whistles” is not always the best fit for you. Be honest about how you intend to use the application and allow that to feed your evaluation of the various toolsets. A good balance of the “right” features is often a better solution than tools with “all” the features.
• Configuration/Customization capabilities – make sure the tool you choose has the ability to be conformed to your business model, navigation preferences, and branding standards.
• Availability of Professional services to support and tailor the CRM solution – make sure the product you choose is well supported and you have access to training staff to evolve and configure the application to your specifications.

Feel free to contact us to discuss how you can transition over to AscendixRE, which provides the power of the Salesforce platform combined with the stability of a 29+ year company that provides both a CRE-specific CRM and a substantial set of professional services.
