Co-sell Coaching: Episode 1, Carve Partners - AMA

Excellent session, Reis! We've just hit Tier 1 ISV Status w/ Microsoft and am curious how effective you've noticed Microsoft's outsourced co-sell desk to be. I've submitted deals well in advance of a close date, only to sit for weeks without response from the Co-Sell Desk. Often times the Microsoft seller is not identified, sometimes they are, but no proactive outreach to assist w/ setting up a first call. Have you experienced this 'co-sell limbo', where you / your customers are left waiting if they're not in Partner Center daily refreshing a deal's status until the seller is identified?
