Secrets to Building a High-Growth Inside Sales Team: 5 Lessons From HubSpot‘s Mark Roberge

Inside sales has emerged as the growth engine powering the revenue of many of today‘s most successful B2B companies. With a scientific approach to hiring, training and managing reps, inside sales teams are able to predictably scale revenue in a fast yet sustainable way.

One of the pioneers of this modern inside sales movement is Mark Roberge, who joined HubSpot as SVP of Worldwide Sales and Services in 2007 when it had just a handful of customers. Over the next seven years, Mark grew HubSpot‘s revenue over 6,000% and expanded the team to hundreds of employees. He chronicled his approach in the bestselling book "The Sales Acceleration Formula" and now teaches it to students at Harvard Business School.

I had the chance to interview Mark and learn his secrets to building a high-velocity inside sales machine. Whether you‘re an early-stage founder just starting to build a sales team or a veteran sales leader looking to take your team to the next level, these lessons from Mark provide a proven roadmap to inside sales success.

1. Develop a rigorous hiring process early

Top-performing sales reps can generate 5-10 times more revenue than an average performer, so identifying and hiring sales stars should be one of your top priorities from day one.

Mark recommends collaborating with your management team to identify the traits of successful salespeople at your company. At HubSpot, they looked for:

• Coachability
• Curiosity
• Intelligence
• Work ethic
• Prior success

By measuring every candidate and rep against this consistent set of criteria, from first interview through ongoing performance evaluations, you can determine which reps have what it takes and which don‘t. And if certain reps aren‘t working out, you need to be willing to let them go quickly before they hurt your culture and bottom line.

The key is to develop this process early, iterate on it, and work out the kinks before you try to rapidly scale your team. With dozens of data points, you‘ll be in a much better position to predictably identify and hire top performers.

2. Take an analytical approach to sales leadership

With an engineering background, Mark was one of the first sales leaders to apply a metrics-driven methodology to growing a sales team. Rather than just relying on feel and intuition, Mark advises immersing yourself in the data:

• Establish the core KPIs that impact revenue – pipeline creation, win rates, sales cycle, deal size, etc.
• Build dashboards to track those KPIs and review them on a frequent basis with your management team to spot issues and opportunities.
• Hire an analytical sales ops person to dive deep into the data and surface insights. Find someone who complements your weaknesses.
• Learn from other data-driven sales leaders. Read their articles and books and try to replicate their success.

Many sales leaders shy away from getting into the quantitative nitty gritty of their business. But with the amount of sales data now available, you can‘t afford not to adopt an analytical mindset in order to keep up with the competition.

3. Don‘t over-automate the human side of selling

Inside sales teams have embraced technology like customer relationship management (CRM) systems, power dialers, email automation, and more to make reps ultra-efficient. However, Mark cautions against using technology as a crutch.

Certain elements of selling require a human touch that can‘t be replaced by even the smartest tech:

• Building trust and rapport with buyers
• Uncovering the customer‘s unique challenges and needs
• Delivering personal value propositions and tailored solutions
• Coaching and developing reps based on their individual deficiencies and learning styles

Elite sales teams strike the right balance – they leverage technology to enhance rep productivity, but continue to focus on developing the skills and behaviors that lead to lasting customer relationships.

4. Hire for potential and train for skills

Many sales leaders make the mistake of looking for reps with tons of experience selling to their exact industry or buyer profile. But Mark argues that is shortsighted.

Instead, screen candidates for their potential – traits like coachability, work ethic, intelligence and an entrepreneurial spirit that are harder to teach. Then, invest heavily in onboarding and training those high-potential hires so they master the specific skillset needed to thrive in your sales environment.

Mark points to Dan Cook, one of the first sales hires at HubSpot, as a perfect example. Dan had no software sales experience but scored off the charts in drive, wit and competitiveness. Through coaching and training, he quickly became one of HubSpot‘s top performers.

5. Specialize roles as you scale

Early on with a small team, it often makes sense to have your reps handling the entire sales cycle – from researching prospects to closing deals and managing accounts. But as you grow, Mark recommends specializing roles to maximize output.

Common ways to specialize include:

• Inbound vs outbound: Have one group of reps follow up with inbound leads and another focused on outbound prospecting.
• Small business vs Mid-Market vs Enterprise: Segment reps by deal size since the sales cycle and buying process vary at different tiers.
• Account Executives vs Account Managers: Split new business and post-sale account growth into separate roles.
• Product Specialists: Have subject matter experts who can give in-depth demos and answer technical questions.

The key is to align your customers‘ buying journey with your sales process, and evolve your team structure as your business matures and your deal flow increases. Ultimately, specialization allows each rep to focus on a narrower piece of the sales cycle and deliver a better customer experience.

The human element

While following these lessons can put you on the fast track to inside sales success, Mark emphasizes that there is no perfect formula.

At the end of the day, sales is still a human-to-human interaction. It requires not just tactics and technology, but also the passion, empathy and competitive spirit to connect with customers and help them achieve their goals.

The best sales leaders never lose sight of that, even as they adopt a scientific approach to growing their inside sales team. By combining the power of data with a genuine desire to add value to customers, you too can build an inside sales growth engine and take your company to new heights.
