Daniele Horton, founder and CEO of Verdani Partners, built her sustainability consulting firm on a simple premise: most clients need five specialized skill sets but cannot justify five full-time hires. Glenn Gow, The Scaling Executive Coach and host of The Scaling Executive Podcast, sat down with Horton to unpack how that model let Verdani grow from a single-founder shop into a firm that supports close to 30 clients and manages sustainability strategy across nearly 12,000 properties in almost 30 countries. When a specialized service business outgrows what a single internal team can deliver, Horton’s fix is not to hire more generalists. It is to assemble a fractional team of specialists, engineers, data analysts, corporate sustainability leads, and communications experts, and rotate them in and out as a client’s needs shift from strategy to implementation. That model saves clients 30 to 60 percent compared to building the same capability in-house.
This episode is for CEOs of specialized consulting or service businesses who are deciding whether to keep hiring in-house as they scale, or build a flexible staffing model that can flex with client demand.
Key Takeaways
- Verdani Partners’ fractional team model, pairing clients with specialists in engineering, data, corporate sustainability, and communications, saves clients 30 to 60 percent compared to hiring the same skill sets internally.
- Verdani now manages sustainability strategy for close to 30 clients and nearly 12,000 properties across almost 30 countries.
- Horton built Verdani after her employer denied a telecommuting request following the birth of her second child. The company that acquired her former employer became her first client.
- Horton’s hiring rule: bring on people who complement her skills, not people who mirror them, even when she personally likes a candidate who doesn’t fill a gap.
- Verdani is running an AI hackathon in July to test how new tools can change service delivery, while Horton personally tests AI tools and builds agents ahead of that event.
How CEOs Can Scale a Specialized Service Business Without Full In-House Hires
Verdani Partners describes itself as an extension of a client’s team rather than an outside consultant. Horton built the firm around a specific gap: a client might need five skill sets to run a successful sustainability program, but rarely has the capital to hire five different specialists. Verdani supplies that team on a fractional basis instead.
The fractional bench includes:
- Engineering and data specialists who track building performance
- Corporate sustainability leads who set program strategy
- Communications specialists who manage reporting and stakeholder messaging
The mix is not static. A client’s program typically starts by needing strategy and planning, then shifts toward implementation as the program matures. Verdani swaps team members and upskills its staff to stay ahead of that shift rather than leaving a client with the wrong specialist at the wrong stage.
The scale this produces is specific: Verdani now supports portfolios that average between 400 and 1,000 assets each, manages sustainability strategy across nearly 12,000 properties in almost 30 countries, and delivers this at 30 to 60 percent lower cost than a client would pay to build the same skill sets internally.
Why Verdani Partners Hires for Complementary Skills, Not Similarity
Before founding Verdani, Horton spent almost ten years as head of sustainability inside a full-service real estate firm, including a stretch retrofitting an entire portfolio during the last real estate recession. She describes working around the clock during that period and watching client-side team members hit the same wall: too much program to run with too few of the right skills in the room.
That experience shaped a specific hiring principle. Horton will pass on a candidate she personally likes if that candidate’s skills duplicate her own, and will hire someone she has less rapport with if that person fills a gap she does not have covered. The standard is complementary skill, not personal fit alone.
The same discipline shows up in Verdani’s track record: the firm was sector leader for three years running on GRESB (referred to as “GRESP” in the interview audio; confirm the correct benchmark name before publishing) and LEED-certified an entire client portfolio, results Horton attributes to building a team with skills she does not personally have rather than a team that thinks the way she does.
How CEOs Should Upgrade Systems Before Past Growth Strategies Stop Working
Horton is direct about where Verdani sits today: what got the firm from a single founder to nearly 12,000 properties across almost 30 countries will not get it to its next stage. That recognition is driving three specific investments: upgrading the firm’s technology stack, building AI into its internal systems, and adding infrastructure and tools ahead of further international expansion.
The trigger for this shift was not a specific incident. It came from watching client portfolios grow past the size where the original operating model still worked cleanly. As Verdani prepares to expand into new countries, Horton is treating internal infrastructure as a scaling requirement, not a maintenance task to defer.
How CEOs Should Balance AI Adoption with Expert Oversight in Regulated Industries
Horton’s team tracks roughly 2,000 data points and KPIs for a single building. That volume of data is the specific reason she has moved to embrace AI inside Verdani rather than treat it as optional. The firm is running an AI hackathon in July to get its team testing how AI can change service delivery, is actively recruiting an AI integrator, and Horton is personally testing multiple AI tools and building AI agents to see what fits the firm’s workflow.
That embrace comes with a named condition. Horton holds that AI will not displace the experts who know how to analyze sustainability data correctly, because bad input still produces bad output regardless of the tool. Her team needs to write the right prompts and validate the output, not hand analysis over wholesale.
Horton also applies the same accountability standard to AI infrastructure that she applies to real estate: she wants the data centers running these tools powered by renewables, their waste heat reused, and their water use minimized. For Horton, adopting AI inside a sustainability-focused firm means holding the technology itself to the same environmental standard the firm applies to its clients’ buildings.
What Scaling CEOs Can Take from Verdani Partners’ Growth
| Principle | What it means in practice | Named evidence from this interview |
| Build fractional, not full-time | Assemble a rotating team of specialists that matches a client’s current stage, rather than hiring a full in-house team for every skill needed | Verdani’s fractional model saves clients 30 to 60 percent while supporting nearly 12,000 properties across almost 30 countries |
| Hire to complement, not mirror | Choose team members whose skills fill your own gaps, even over candidates you personally prefer who duplicate what you already do | Horton’s hiring discipline helped Verdani earn three years as GRESB sector leader and LEED-certify an entire client portfolio |
| Revisit infrastructure before it becomes a bottleneck | Treat “what got you here” as a warning sign, and invest in systems ahead of the next stage of growth, not after strain shows up | Verdani is upgrading its tech stack and building AI-enabled infrastructure ahead of further international expansion |
| Use AI for analytics, keep experts on judgment | Apply AI to process large data volumes, but keep named experts responsible for prompts, validation, and implementation decisions | Horton is personally testing AI tools and building agents ahead of Verdani’s July hackathon, while requiring expert review of AI output |

Frequently Asked Questions
How can a CEO scale a consulting business without hiring a full in-house team for every client?
When a specialized consulting firm’s clients need five or more skill sets but cannot justify five full-time hires, Daniele Horton of Verdani Partners assembles a fractional team of specialists who rotate based on the client’s stage, from strategy planning to implementation. This model cuts client costs by 30 to 60 percent compared to building the same capability in-house.
How should a CEO decide who to hire as the company grows?
Daniele Horton hires for complementary skills rather than similarity. She passes on candidates who mirror her own strengths, even ones she personally likes, and prioritizes people whose engineering, data, or communications expertise fills a gap on the team, a discipline she credits with helping Verdani scale past the point where she tried to run the firm alone.
How should a CEO use AI without losing control over data quality?
Daniele Horton uses AI to accelerate analytics across the roughly 2,000 data points and KPIs Verdani tracks per building, which frees her team to focus on implementation. She holds that bad input still produces bad output regardless of the tool, so named experts must write the prompts and validate the results before any decision gets made.
