The chat thread that is also a running agreement.
Handshake combines messaging, task checklists, and client-specific branding into one clean space. Every checked box is a small promise kept. Zero clutter, maximum clarity.
Our Philosophy
Eliminating the gaps between work items and chat conversations.
Agencies waste hours digging through messy Slack channels, email threads, and task management systems just to check if a client has approved a layout or uploaded assets.
Handshake was built to merge project context directly into the stream. By tracking tasks, status metrics, and file attachments in a single space, we establish a clean, immutable history of alignment.
Frame-accurate video reviews & pinpoint visual feedback.
Stop giving timestamp feedback in disconnected emails. Handshake brings an NLE timeline directly into your workspace chat, with 60 FPS playback, real audio waveforms, and precision coordinate pins.
