Andsend vs Happenstance

Andsend is relationship intelligence software for professional relationship management and business development. It uses conversation history, role changes, personal milestones and web signals to help users choose whom to contact and when. Suggested messages draw on that context, but users can review, edit or skip them before sending. A unified inbox brings LinkedIn and email conversations together. Team features include shared relationship visibility, warm-path discovery, introduction requests and shared notes. The product lists Gmail, Outlook, Google Calendar, Outlook Calendar and LinkedIn; Pro also lists Salesforce, HubSpot and Pipedrive integrations. A Chrome extension is required to connect LinkedIn, and LinkedIn must be used in the same browser. Andsend is available on the web and as an extension. Pricing starts at €49/user/mo, and a free trial is available. Andsend says data is encrypted in transit and at rest and generally stored in the EU, with some model-provider subprocessors as exceptions. Its security FAQ says SOC 2 and ISO 27001 certifications are on its roadmap.

Happenstance is a people-search service for finding people in your existing network and paths to introductions. It draws relationship signals from email headers, meetings, connections, follows, and contacts, then ranks people by how well you know them. Search results name matches, explain why they surfaced, and show a direct, friend, or group route. It connects to Gmail, Outlook, Google Calendar, Google Contacts, LinkedIn, Twitter, and Instagram. Friends can share networks mutually; groups pool member networks for teams, funds, cohorts, or communities, and groups are free and unlimited. For agents and applications, Happenstance offers a REST API, MCP server, OpenAPI specification, and CLI, and it works with ChatGPT, Claude, Claude Code, and OpenClaw. Its iPhone app includes natural-language search, ranked warm paths, saved lists, introduction drafting, and network updates. Email and direct-message content and attachments are not sent to its servers; it uses sender, recipient, and timing metadata. The Free plan has Chat usage limits. Team is $24 a month per seat; Pro is $30 a month.
