Winning by Going Narrow: How Mobile Locker Uses Niche Positioning to Dominate Pharmaceutical Sales Enablement

The sales enablement market is crowded — full of heavily funded competitors with massive teams and polished marketing engines. But Mark Stralka, founder and CEO of Mobile Locker, has carved out a profitable, defensible position by doing what many SaaS founders resist: focusing deeply on one high-value niche.

Mobile Locker isn’t trying to be all things to all sales teams. Instead, it’s built specifically for pharmaceutical and life sciences companies, providing sales and marketing teams with a central hub for content, videos, and tools — all accessible, trackable, and easy to share with healthcare professionals.

Lesson 1: Casting Too Wide Can Kill Momentum

When Stralka bought Mobile Locker back in 2016, his first instinct was to market it as a general-purpose sales enablement tool. He targeted “any sales team,” cycling through contractors and sales approaches. The result? Slow growth, inconsistent traction, and a lack of clarity on who the ideal customer really was.

The breakthrough came when he doubled down on Mobile Locker’s existing strength — the pharmaceutical industry. These customers already had budget, an urgent need for remote engagement, and a history of long-term contracts.

Buyer intelligence insight: The fastest path to scalable SaaS growth often comes from serving one buyer segment better than anyone else, not trying to win the whole market.

Lesson 2: Niche Positioning Improves Sales and Retention

By narrowing focus, Mobile Locker’s sales team could speak the buyer’s language — referencing FDA regulations, medical sales workflows, and specific field rep challenges. The messaging shifted from generic “sales enablement” benefits to clear, pharma-specific outcomes like faster HCP engagement, remote content delivery, and compliant tracking.

This wasn’t just a sales win — it improved retention. Once Mobile Locker became integrated into a pharma company’s daily workflow, it became the default platform for new reps from day one, making churn far less likely.

Lesson 3: Small Company, Big Advantage

Stralka doesn’t see Mobile Locker’s small size as a disadvantage. In fact, it’s a differentiator:

• Faster response times — feature requests can be implemented in days, not quarters.

• Personalized onboarding — no layers of account managers.

• Adaptability — the product can pivot quickly to support new sales realities (like COVID’s shift to remote engagement).

Agency takeaway: Your size can be part of your positioning. Big competitors can’t match the responsiveness and customization of a small, focused SaaS.

Lesson 4: Web Experience Should Qualify and Convert

As Mobile Locker tightened its niche, its marketing materials evolved. The website shifted from a broad, feature-heavy pitch to industry-specific messaging, case studies, and proof points designed to qualify pharma buyers and start a consultative sales conversation.

Web design insight: For B2B SaaS, your site should act like a high-performing SDR — filtering for the right prospects and guiding them to the next step, not just listing features.

Lesson 5: Focus Protects You from Market Shocks

COVID could have been devastating for Mobile Locker. Trade shows — once a part of their offering — disappeared overnight. But the core niche, pharma sales, needed Mobile Locker more than ever. Reps had to replace in-person visits with compliant, trackable digital outreach. Mobile Locker’s remote engagement features became mission-critical, fueling growth during a downturn.
