When Mark Roberge was hired to lead HubSpot’s sales team, he was the third employee. The other two were the founders — Brian Halligan and Dharmesh Shah. Mark had no sales experience. He was a mechanical engineer.
So he read every sales book he could find and asked everyone he knew with sales experience for advice. His goal was simple: build a recurring, scalable sales engine.
Used to engineering formulas, he expected to find measurable, repeatable mechanisms in sales. Instead he found anecdotes, intuition, and methodologies that were hard to evaluate empirically. He decided to write his own system. He called it The Sales Acceleration Formula. He took HubSpot’s sales from $0 to $100 million in seven years using it.
The framework translates almost directly to a residential developer scaling from one community to several. Four parts.
1. The hiring formula
Everything starts with hiring the right sales advisors. Roberge’s premise: if you can find a way to identify people who will be naturally successful in your sales context, you can scale predictably.
Four steps:
1.1 Define the ideal characteristics for a sales advisor in your business. Brainstorm every trait that matters for selling residential units in your specific market. Write them all down. Score them 1–10 in importance.
1.2 Build an evaluation system for each trait. Roberge identifies five traits that recurred across high-performing salespeople:
- Coachability. Run a roleplay. Ask them to sell you something. Then ask them to self-assess. Then run it again with different feedback. Watch how they integrate input.
- Curiosity. Did the candidate research your projects, your market, your developer track record before the interview? Did they ask substantive questions?
- Past success. In sports, school, a previous job. People with a track record of winning at something tend to repeat the pattern.
- Intelligence. Give them a real problem your sales team faces and ask them to walk through how they’d think about it.
- Work ethic. Are they on time? Do they respond fast to email? Reference checks. Behavioral interview questions.
1.3 Weight the traits and measure continuously. Some traits matter more than others. At an early stage, coachability is often the most important — the new hire has to learn your specific buyer. As the team grows, other traits gain weight.
1.4 Recruit on networks. The best sales advisors usually aren’t actively job-hunting. Build a steady inbound recruiting flow on LinkedIn the same way you build a marketing flow.
2. The training formula
You can’t just shadow your best salesperson and hope new hires absorb the magic. Roberge prescribes a training program that develops three things:
2.1 Process-based training. Multiple trainers, each specializing in a part of the buyer journey. Tests and certifications at each phase. The goal is to measure capability, not just attendance.
2.2 Buyer empathy. Every advisor should understand the buyer journey from the buyer’s side. Three components:
- Buyer journey. How a residential buyer goes from “we should look around” to signed contract over 90 to 180 days.
- Sales process. The steps the developer’s sales process takes, mapped to where the buyer is on their journey.
- Qualification matrix. A clear framework for scoring where each lead is.
2.3 Sales-advisor superpowers. Each advisor has different strengths. Train each one to lean into theirs. Some close better at the model home; some close better on the phone.
3. The management formula
Coaching and metrics are the dominant inputs.
3.1 One skill at a time. Each week, you and the advisor pick one specific skill to improve. Trying to fix five things at once produces no improvement on any of them.
3.2 Stage-specific evaluation. Look at metrics by buyer-journey stage so you can target coaching where it lands.
3.3 Measure everything. If it’s not measured, it doesn’t change.
3.4 Compensation that drives behavior. The compensation plan is the most powerful management lever you have:
- Hunt plan. Aggressive new-buyer acquisition with high upfront commission, factoring lifetime value.
- Customer-success plan. Compensation tied to buyer satisfaction post-close (and warranty NPS).
- Long-term plan. Reward referrals and repeat business across multiple projects.
- Contests. Best for short-term goals. Make them team-based, tied to specific outcomes, with a meaningful prize. Don’t run them constantly — they lose force.
4. The demand-generation formula
HubSpot’s go-to-market is inbound. The sales team is fed by content, search, AI search citations, social, and email — not by cold calls.
For a residential developer, the same logic applies. Cold outbound is slow, expensive, and unscalable. The high-leverage demand machine is:
Quality content + lead-capture tools + consistency + presence on the platforms buyers actually use + occasional paid acceleration.
The sales advisor’s role shifts from cold caller to consultant. Buyers come to you because the content earned their trust during their research. The sales advisor’s job is to walk them across the line — not to convince them to start the conversation.

What this looks like for a residential developer
Most regional developers underinvest in the sales operation. They hire one or two advisors, train them by osmosis, and live with whatever conversion rate emerges. Roberge’s framework forces a more deliberate approach:
- Hire against a clear profile, not a gut feeling.
- Train against the buyer journey, not the sales playbook of the last company you worked at.
- Coach one skill at a time and measure the result.
- Pay people for the behaviors you actually want to see.
- Feed the team inbound demand instead of asking them to generate their own.
