Developer-first unified API platform for building native GTM integrations — one API to read and write across CRM, sales engagement, chat, marketing automation, and dialer tools.
Developer-first unified API platform for building native GTM integrations — one API to read and write across CRM, sales engagement, chat, marketing automation, and dialer tools.
Vessel is a developer-first unified integration platform for B2B SaaS teams that need to ship customer-facing integrations with dozens of GTM tools — CRM, sales engagement, chat, marketing automation, and dialer categories — from a single API. Rather than building and maintaining per-vendor connectors, product engineers integrate once and Vessel handles OAuth, schema normalization, rate limits, and writes. Pre-built categories include CRM (Salesforce, HubSpot, Zoho), Sales Engagement (Apollo, Outreach, Salesloft), Chat (Slack, Microsoft Teams), Marketing Automation (Customer.io, Mailchimp, ActiveCampaign), and Dialer (Aircall, Dialpad, RingCentral). Vessel is SOC 2 Type II compliant, offers a free developer tier with 5 sandbox connections and unlimited API calls, and reserves whitelabeling for the Custom plan.
