How Preston Baker built an elite agency model on Greenhouse OS

Discover why one of the UK’s most innovative estate agencies walked away from restrictive, generic CRM software to unlock the true power of automation and unlimited customisation.

The Problem: The trap of "out-of-the-box" software

Many agencies reach a point where standard, off-the-shelf software stops being a tool and starts being a ceiling. For a forward-thinking brand like Preston Baker, a standard CRM simply couldn’t keep pace with their vision for growth.

“Out-of-the-box” software is built to serve the lowest common denominator. It forces every agency into the exact same rigid workflows, the same templates, and the same operational limits. When an agency wants to innovate—whether that’s empowering an entrepreneurial broker network or executing advanced client strategies—generic software answers with a hard no. The business becomes trapped by the limitations of its technology.

The Challenge: The risk of outgrowing your system

Walking away from an established system is always a major decision, especially for a high-volume business. Changing your core system is a big deal, and Preston Baker knew they needed more than just a new piece of software; they needed a true technology partner capable of shifting them from “good enough” to game-changing growth without risking operational chaos.

The Transition: Setting up for seamless success

The transition to Greenhouse OS was designed to completely dismantle the old software-switch nightmare. Built on top of Salesforce—the world’s most robust CRM infrastructure—the migration focused on mobilizing, rather than just moving, the agency’s data:

Instant, hands-on launch training: Instead of leaving the team to figure out a complex new system via dry training videos, on-site, hands-on support ensured everyone hit the ground running from day one.

Data mobilisation: Rather than just dumping old records into a new database, historical data was fully activated, transforming stagnant files into active, revenue-generating property insights.

The absolute freedom to innovate: Preston Baker instantly gained the ability to adapt the software to their exact business model, rather than forcing their business to adapt to a software supplier.

The Outcome: Four ways the agency has transformed

By leaving generic, rigid systems behind, Preston Baker unlocked an entirely new tier of performance, powered by deep customisability and native automation:

Limitless Customisation: Greenhouse OS completely flipped the dynamic. The agency is now fully in charge of its own software, meaning they have the unrestricted freedom to design custom workflows that fit their market perfectly.

Advanced AI Productivity: Repetitive administrative tasks have been stripped away. Built-in AI and automation do the heavy lifting, allowing agents to spend less time typing and more time building relationships.

Mobilised Data Activation: Historic database records aren’t just taking up digital space—they are actively filtered and mobilised to help the team predict client needs and unlock hidden valuations.

A Scalable Foundation: With a tailored, ultra-reliable operational setup, the agency has built a sustainable business model that supports high-margin growth without burning out the team.

"Changing your CRM at any point is a big deal and you want to make sure that you're moving with the right partner. The business benefits that you're going to get from it—by moving from something which is usually out of the box and works 'okay' to something which is adaptable and can really help you grow your business—is game-changing."
