Integrity Solutions vs ASLAN.

These two firms make the same bet from different decades: the sale is won or lost on whether the buyer believes the seller is on their side. Integrity Solutions has run that thesis since 1968, when Ron Willingham codified Integrity Selling, and now delivers it through a certified-facilitator licensing model across 130+ countries, with deep roots in financial services and healthcare. ASLAN Training, founded in 1996 by Tom Stanfill and Tab Norris, frames it as Other-Centered Selling: buyer receptivity must precede seller influence, an argument Stanfill makes at book length in unReceptive. The overlap in philosophy makes the differences matter more: delivery model, inside-sales depth, reinforcement technology, and two different kinds of review record.

Integrity Solutions, what it is and where it wins

Integrity Solutions was founded in 1968 by Ron Willingham, who codified Integrity Selling around a premise that has aged better than most sales fashions: trust precedes influence, and customers buy from people they believe are acting in the customer's interest. The framework structures the conversation across six steps, Approach, Interview, Demonstrate, Validate, Negotiate, and Close, and layers a Behavior Styles model on top so sellers adapt to different stakeholder preferences. The firm relocated to Nashville in 2011 and has built one of the oldest and most internationally distributed practices in the category, delivering in 130+ countries through certified-facilitator licensing.

Integrity Solutions wins at consistent scale in trust-led verticals. Financial services, healthcare, and insurance organizations value the emphasis on customer trust as a precondition for the sale, and published references include Principal Financial Group, Mutual of Omaha, and Nationwide, all large field forces running the framework across regions. The licensing model is the operational advantage: an organization certifies internal or local facilitators and gets the same program in every market without rebuilding it per region. The 4.7 across 58 G2 reviews is a solid verified base for a firm this age. The tradeoffs are positioning and modernity. Integrity Selling reads more interpersonal-skills than complex B2B process, SaaS buyers find it underweight on qualification rigor compared with MEDDICC-aligned providers, and the delivery model is less digital-native than Imparta or Winning by Design.

ASLAN, what it is and where it wins

ASLAN Training was founded in 1996 by Tom Stanfill and Tab Norris, both still active in leadership, and operates ten regional US offices with delivery in 47 countries and 17 languages. Other-Centered Selling argues that buyer receptivity must precede seller influence: if the buyer does not believe the seller is acting in their interest, no framework or closing technique recovers the conversation. Stanfill's book unReceptive frames the work around four resistance triggers and four corresponding seller behaviors, which gives the philosophy teeth in practice. Programs span inside sales, field sales, and sales leadership, with the ASLAN+ platform layering AI-enabled coaching and ongoing practice on top.

ASLAN wins where resistance is the problem and the phone is the channel. The Inside Sales School treats inside selling as a discipline with its own behaviors and metrics rather than a junior version of field work, which most field-heavy peers underserve, and one G2 reviewer credits the approach with cutting ghosting and lifting meeting-to-opportunity conversion for their inside team. Thirteen consecutive years on the Selling Power Top Sales Training Companies list through 2025 signals durability, and the published client roster, HubSpot, DoorDash, American Airlines, Abbott, Cisco, Cox, Aflac, HP, Shaw, Nationwide, Home Depot, Takeda, and Hilti, spans far more industries than the firm's modest SaaS-circle fame suggests. The tradeoffs: a thin 12-review G2 sample at 3.9, lower brand awareness among SaaS founders than Winning by Design or Force Management, and a name for the methodology that can sound soft to a bottom-funnel CRO until they see the resistance mechanics in detail.

Side by side

Head to head, dimension by dimension

Methodology and philosophy

Philosophically these are siblings. Trust precedes influence and receptivity precedes influence describe the same conviction: technique applied to a closed buyer is wasted. The difference is where each framework puts its structure. Integrity Selling structures the conversation itself, six named steps a seller can walk in order, with Behavior Styles adapting the delivery to the stakeholder across the desk. Other-Centered Selling structures the resistance: four triggers that close a buyer down and four seller behaviors that reopen the conversation, which makes it less a call script and more a diagnostic sellers apply moment to moment. Teams that want a repeatable conversational sequence will find Integrity Selling easier to install. Teams whose sellers follow scripts fine but still get stonewalled will get more from ASLAN's resistance work.

Delivery and reinforcement

The delivery models are the sharpest practical difference. Integrity Solutions licenses the methodology: your organization certifies facilitators, internal or local, and runs the program itself with consistency across 130+ countries, which is why its footprint concentrates in large field organizations. Reinforcement lives in Integrity Coaching, which arms frontline managers to keep the framework alive. ASLAN delivers through its own bench, in-person and virtual from ten regional offices into 47 countries, and reinforces through ASLAN+, where AI-enabled coaching gives sellers ongoing practice between sessions. The honest trade: Integrity Solutions hands you a durable internal capability but depends on your facilitators' quality, while ASLAN keeps delivery quality in its own hands and adds modern digital reinforcement, at a higher tier and with less multiplication at extreme scale.

Team fit

Integrity Solutions fits mid-to-enterprise organizations in financial services, healthcare, insurance, and adjacent trust-led verticals where long-cycle relationship selling is the norm, and it especially fits multi-country organizations that need one consistent program everywhere. It is a weaker match for SaaS-native motions where qualification rigor matters more than interpersonal trust, and for SMB buyers who want a packaged subscription. ASLAN fits mid-market to enterprise teams running inside and field motions together, with healthcare, financial services, telecom, and hospitality heavy in its client base, and it particularly suits leaders who have watched aggressive methodologies fail against sophisticated buyers. It is a weaker match for cultures wedded to confrontation-style Challenger selling or sharp MEDDIC qualification, and for buyers who want contemporary SaaS revenue-architecture vocabulary.

Pricing posture

Integrity Solutions sits in the mid tier, and the licensing structure changes the math: you pay for program licensing and facilitator certification rather than per-seat fees alone, so unit cost falls as deployment grows, which is the right shape for a five-country, thousand-seller rollout. ASLAN sits in the mid to high tier, priced by program scope, team size, delivery format, and whether ASLAN+ reinforcement is included, the shape of a delivered engagement rather than a licensed capability. Neither publishes rates, so both require direct quotes. The budget question that decides it: do you want to own the delivery capability, which favors Integrity Solutions, or buy delivery and digital reinforcement as a service, which favors ASLAN?

Proof and reviews

The review records diverge more than the philosophies. Integrity Solutions holds a 4.7 across 58 G2 reviews, verified May 2026, one of the more substantial verified bases among legacy providers, with sentiment concentrated where the firm concentrates: financial services and healthcare. ASLAN's G2 sample is 12 reviews at 3.9, thin enough that the directory's own read is that the Selling Power award record, 13 consecutive years through 2025, carries more weight than the aggregate. That is an honest asymmetry buyers should sit with: one firm's quality claim rests on verified buyer reviews, the other's on sustained industry recognition and a published client roster. Both claims are defensible. They are not the same kind of evidence. Category-wide context is in the State of Sales Training 2026 report.

What buyers say, where reviews exist

What buyers like about Integrity Solutions

The G2 sentiment concentrates in the verticals the firm serves deepest. A sales leader at a regional financial services firm writes that Integrity Selling worked particularly well for wealth-management advisors because the trust-precedes-influence frame matched the client relationship. Industry commentary highlights the certified-facilitator model giving multinational buyers consistent delivery in markets few peers can credibly serve, which matches the 130+ country footprint.

What buyers criticize about Integrity Solutions

The recurring criticisms are about category fit rather than quality. The methodology's positioning feels more interpersonal-skills than complex B2B process, which can undersell it in a rigorous enterprise evaluation. SaaS buyers find it underweight on qualification rigor next to MEDDICC-aligned providers. And the delivery model is less digital-native than Imparta or Winning by Design, so buyers expecting platform-led reinforcement should probe what the licensed program includes.

What buyers like about ASLAN

The strongest verified note is operational: a VP of sales at a mid-market technology company writes on G2 that Other-Centered Selling reset how their inside team approached cold outreach, reducing ghosting and lifting meeting-to-opportunity conversion meaningfully. Selling Power commentary credits ASLAN with bringing a buyer-empathy lens that is distinct in a crowded category, and the 13-year run on its Top list is the longest-duration signal either firm on this page holds.

What buyers criticize about ASLAN

The review base itself is the first criticism: 12 G2 reviews at 3.9 is both thin and lower than peers, and buyers doing diligence have little verified material to work with, so direct references matter. Beyond that, brand awareness in the SaaS founder community trails Winning by Design and Force Management, the Other-Centered name can read as soft to bottom-funnel CRO audiences without prior exposure to Stanfill's book, and the vocabulary is less SaaS-native than peers chasing the same enterprise buyer.
