TL;DR: Overvue costs $24.99/month for individuals and $50/seat for teams, with unlimited scenarios and strong gamification to drive daily practice. Second Nature is enterprise-focused with custom pricing and robust LMS features but lacks gamification and transparent pricing. For small teams under 20 reps who need cold calling practice, Overvue. For large B2C teams (especially insurance) with existing training infrastructure, Second Nature.
Quick Comparison
When to Choose Overvue
Pick Overvue if you're:
- Sales team under 20 reps
- Or you're a solo SDR/Founder led sales
- Focused specifically on B2B cold calling
- Working with a budget under $200/seat/month
- Looking for gamification to drive consistent practice
- Want transparent, publicly available pricing
- Need to create custom scenarios quickly (under 5 minutes)
Overvue works well for startups and SMBs who need their reps practicing cold calls daily without enterprise complexity or price tags.
When to Choose Second Nature
Pick Second Nature if you're:
- Running an enterprise sales team (50+ reps)
- Operating in B2C or regulated industries (especially insurance)
- Need full LMS/CMS capabilities beyond just roleplay
- Have extensive existing training materials to convert
- Require specific compliance certifications (GDPR, SOC2, CCPA)
- Can handle custom enterprise pricing
Second Nature fits organizations with established training programmes who need a comprehensive platform rather than just cold call practice.
Pricing Breakdown
Overvue:
- Solo plan: $24.99/month
- Team plan: $50/seat
- All plans: Unlimited custom scenarios
- Self-service signup, no sales calls required
Second Nature:
- Custom enterprise pricing (not publicly disclosed)

Overvue's transparent pricing makes budgeting straightforward. Second Nature's custom pricing means you'll need procurement involved and multiple sales calls before knowing actual costs.
Feature Comparison
Voice Realism and Conversation Flow
Both platforms offer realistic AI voices, but there's a difference in underlying technology.
Overvue uses the latest LLM models purpose-built for cold calling. The AI responds in real-time, throws realistic objections, and mirrors actual prospect behavior. Reps consistently report feeling nervous during practice calls because they're that realistic.
Second Nature launched in 2018 and has upgraded to newer AI models over time. Some users note the conversational flow can feel less natural compared to platforms built on the latest LLMs from the ground up. The AI is realistic, just not quite as fluid in back-and-forth exchanges.
Gamification and Engagement
This is where the platforms differ most.
Overvue centers on gamification. Reps earn XP for strong performance, climb ranks from Wood I to Master XII, compete on leaderboards, and unlock achievements. Teams can run competitions with custom rewards. The gamification isn't tacked on—it's the core mechanism driving daily practice.
Second Nature has no gamification features. It's a straightforward training platform with performance analytics and manager dashboards, but no competitive elements or achievement systems.
If your team needs external motivation to practice daily, Overvue. If your reps are self-motivated and you just need comprehensive training infrastructure, Second Nature.
Scenario Creation Speed
Overvue creates custom AI prospects in under 5 minutes. You describe your target buyer, adjust personality traits and difficulty, and start practicing immediately. No waiting, no approval workflows.
Second Nature lets you upload existing documents, presentations, and training materials to automatically generate scenarios. This is powerful if you've got extensive content to convert, but slower than Overvue's approach. Some teams report 2+ weeks for custom bot creation.
Cold Calling vs General Sales Training
Overvue is laser-focused on cold calling. The platform, voice quality, objection handling feedback, and gamification are all optimized for outbound phone practice.
Second Nature covers broader sales training—cold calls, discovery, demos, compliance conversations. This makes it versatile but less specialized. The platform serves call centers, insurance agents, and general B2C sales roles beyond just outbound.
For pure cold calling practice, Overvue's specialization shows. For comprehensive sales training across multiple conversation types, Second Nature's breadth matters.
Team Management and Analytics
Overvue provides basic team features: performance tracking, who's practicing, leaderboards, and interview assessment mode. It's straightforward and focused on driving practice rather than comprehensive training administration.
Second Nature offers full LMS capabilities. Manager dashboards show detailed analytics, skill gap identification, content management systems, and integration with existing training infrastructure. It's enterprise-grade training administration.
Small teams find Overvue's simplicity refreshing. Large enterprises with dedicated enablement teams appreciate Second Nature's depth.
B2B vs B2C Focus
Overvue targets B2B SaaS cold calling. The scenarios, objection types, and feedback assume you're booking meetings with business buyers.
Second Nature skews B2C, particularly insurance and regulated industries. The platform includes compliance-focused training, script adherence tracking, and features built for consumer-facing sales conversations.
This isn't a limitation—just know what you're optimizing for.
Real-World Fit Scenarios
Scenario 1: 8-person SDR team at a SaaS startup, $50k/year budget
- Choose Overvue
- Total cost: $3,840/year ($50/seat × 8 reps × 12 months - 20% discount for yearly plan)
- Unlimited scenarios, gamification drives adoption, self-service setup
Scenario 2: 200-person insurance sales team, $500k/year training budget
- Choose Second Nature
- Need: Compliance training, existing content conversion, full LMS
- Budget supports enterprise pricing, requires comprehensive features
Scenario 3: Solo SDR preparing for interviews
- Choose Overvue
- Cost: $24.99/month
- Create custom scenarios matching target companies, practice until ready
Scenario 4: 50-person B2C sales team with detailed playbooks
- Consider Second Nature
- Can upload existing materials for scenario creation
- Budget likely supports custom pricing
- Though lacks gamification for driving consistent practice
What Users Actually Say
Overvue users consistently mention the realism ("I was surprisingly nervous") and how the gamification makes practice feel like a game rather than training. The transparent pricing and immediate setup appeal to teams who want to start practicing today, not in three weeks.
Second Nature users praise the comprehensive platform and ability to convert existing training materials. Enterprise teams value the LMS features and compliance capabilities. Common complaints center on cost, lack of engagement features, and occasional robotic feel to conversations.
Bottom Line
These platforms serve different buyers.
Overvue wins for small to mid-size B2B teams who need cold calling practice with transparent pricing and engagement features that drive daily use. The $24.99 entry point removes friction for solo reps, and the $50/seat team pricing scales affordably.
Second Nature wins for large enterprises, particularly B2C and insurance, who need comprehensive training infrastructure beyond just cold calling. The investment makes sense when you're training hundreds of reps and need full LMS capabilities.
The wrong choice is picking Second Nature for a 10-person team because "enterprise = better." You'll pay exponentially more for features you won't use. Similarly, don't choose Overvue if you need to train 200 insurance agents on compliance scripts—you need Second Nature's breadth.
Match the tool to your actual needs: team size, budget, B2B vs B2C, and whether gamification matters for adoption.
Frequently Asked Questions
Can Second Nature handle cold calling practice like Overvue?
Yes, Second Nature supports cold calling scenarios alongside other sales conversations. However, it's not specialized for cold calling the way Overvue is. The platform serves broader training needs including discovery, demos, and compliance conversations. If cold calling is your primary focus, Overvue's specialization typically delivers better results.
Does Overvue work for B2C sales teams?
Overvue focuses on B2B cold calling, so B2C teams may find the scenarios, objection types, and feedback less relevant. Second Nature is purpose-built for B2C, particularly regulated industries like insurance that need compliance training alongside sales practice.
How do I know which platform my team will actually use?
Test adoption patterns in your org. If your reps are competitive and respond to gamification, Overvue's XP/ranking system drives significantly higher practice rates. If your team is self-motivated and prefers straightforward training without game elements, Second Nature's approach works. The best platform is whichever one gets reps practicing 15 minutes daily.
Can I switch platforms if I pick the wrong one?
Yes. Overvue's monthly pricing means no long-term commitment—cancel anytime. Second Nature likely involves annual contracts given the enterprise focus. Start with trials when possible: Overvue offers free trials, Second Nature offers demos. Test with your actual team before committing budget.
What if I need features from both platforms?
You're probably an enterprise team ($200+ seats) wanting Overvue's gamification with Second Nature's LMS depth. Consider Hyperbound as an alternative—it offers enterprise features with some gamification, though at enterprise pricing. Or use Overvue for cold calling practice specifically while maintaining your existing LMS for broader training.
