“Spike improved workflow between our teams and clients since they had a collaborative workspace. The entire project history & needed files in one place.”
Spike is an amazing team comms platform. Imagine Slack but inside your email, & with everyone you need - team members, clients and vendors too! Our team loves Spike!
My company started using Spike a year ago & the team feels like it’s vastly improved our productivity. It’s amazing to not have to switch back & forth between a million apps!
I had something like 90K unread emails before switching to @SpikeNowHQ. I’m down to just 2K emails. Inbox 0, here I come!
"I chose Spike because it quickly solved my biggest problem—the overwhelming feeling that there are more emails than time in the universe."
2022 was great for the team. Engagement was fluid because of @SpikeNowHQ & the sense of community got reinforced. We accomplished more & work became play. Boost your productivity in 2023 & try Spike!
The app is extremely useful and productive, and it's user support is amazing! Hope it will keep improving with exclusive features that make it different from Gmail.
