You already run your exec's calendar, inbox and travel. Comtev takes the leadership event off your plate by doing the asking, pricing and chasing for you, so you make the calls and skip the back-and-forth.

The offsite shows up the way it always does. A two-line message between two meetings: "Let's get the leadership team together for two days next quarter. Somewhere nice. Sort it out." Then it's yours. You're emailing venues for availability, pinging caterers for menus, holding hotel rooms you might not need, and building a budget in a spreadsheet that goes stale the moment someone replies. You become the human spreadsheet, chasing quotes from suppliers who go quiet for four days, then chasing fourteen people for travel dates and dietary needs, all in the cracks between your exec's actual day.
It's 8:40 and your exec wants the offsite "moving" before the 9am. You forward the two-line brief into Comtev, add the leadership list and the two stakeholders who know everyone's travel plans, and go back to prepping the standup. By lunch the collaborator has chased and collected eleven of fourteen guests, three venues have sent real quotes, and Comtev has already pulled the caterer's per-head down. Mid-afternoon you spin up a second version with the lakeside venue to see how it lands against the city hotel, and the whole budget rebuilds in seconds. At 5pm you drop two clean proposals into your exec's inbox with live totals under each. They reply: "Go with the lake one." Done.
I used to spend a week being the inbox between fourteen people and six suppliers. Now I send the brief, it does the chasing and the haggling, and I just hand my CEO two costed options to choose from.
