Terasu

Terasu is a shared workspace for B2B sales and implementation projects. Long enterprise deals scatter context everywhere. Proposals sit in email, decisions happen in chat, requirements live in a spreadsheet, and by the time procurement, security and finance join the conversation, nobody can say exactly what was promised or why. Terasu keeps all of it in one place. Each deal or onboarding project gets a Room. Pages, documents, messages, tasks and stakeholders live inside it, shared with the customer, with permissions that keep internal notes internal. The reasoning behind each decision stays in the Room, not just the files. What you get: - Rooms: one shared workspace per deal or implementation project - Engagement tracking: see which materials stakeholders actually opened and reacted to - Room-aware AI: summaries of open items and next steps, answered only from that Room's content, with sources cited - Tasks and messages: next steps tracked where the context already is, plus Slack integration - Stakeholder mapping, content intelligence and deal health scoring on Business plans and up - Access control that separates customer-facing material from internal-only material - An audit trail showing how decisions evolved Pricing: Free (2 users, 3 rooms, 500MB), Starter 9,800 JPY/month, Business 29,800 JPY/month, Enterprise custom. 14-day free trial on paid plans; no credit card required for Free. Privacy: communications are encrypted, access is controlled per Room, the AI references only the Room you are in with no cross-workspace access, and your content is never used to train AI models. Customer-visible actions require approval before they run. Built by koromo Inc.
