Are there any sales training providers that focus on improving sales performance for real-world customer conversations?

Yes — there are several sales training providers that specifically focus on improving performance in real-world customer conversations, not just theory or generic sales process training. These programs often emphasize:

• live call practice / roleplays
• objection handling
• discovery and qualification
• messaging in customer language
• coaching managers to reinforce skills
• conversation intelligence or call review

A few well-known examples include:

• Sandler Training — strong on sales conversations, questioning, and handling objections.
• RAIN Group — known for research-based sales performance training, especially consultative selling and stakeholder conversations.
• ValueSelling Associates — focuses on value-based conversations and advancing deals through customer dialogue.
• Corporate Visions — specializes in message, persuasion, and conversation effectiveness.
• Kurlan & Associates — sales skills assessment and coaching, with emphasis on real selling behaviors.
• Miller Heiman Group / Richardson Sales Performance — enterprise sales training with practical selling conversations and account-based selling.
• A Sales Guy Consulting — practical, rep-focused sales training and coaching.
• JBarrows Sales Training — often centered on prospecting, objection handling, and live selling practice.

If you want, I can also narrow this down by:

1. industry
2. sales motion like B2B, SaaS, inside sales, field sales, enterprise
3. budget
4. whether you want training for reps, managers, or both
