## Summary

Vessel provides unified CRM and sales tool APIs enabling B2B SaaS products to natively integrate with Salesforce, HubSpot, and other go-to-market platforms.

## Company Overview

Vessel is a developer tools company founded in 2022 that provides unified APIs for CRM and sales technology integrations, allowing B2B SaaS products to connect with customers' Salesforce, HubSpot, Pipedrive, and other GTM tools through a single normalized API. The company targets revenue intelligence, sales engagement, and analytics tools whose primary value depends on seamless data access to and from customer CRM systems. Building and maintaining native CRM integrations is notoriously complex given the depth of Salesforce and HubSpot's data models, authentication complexity, and rate limiting requirements. Vessel abstracts these complexities into a unified data model and connection management platform that reduces integration development time from months to days. The company raised $5M and serves B2B SaaS companies whose products are embedded in the sales and marketing tech stack. Vessel handles OAuth connection management, data normalization across CRM schemas, webhook forwarding, and write-back operations, providing a complete bidirectional integration layer. The platform is particularly valuable for startups in the GTM tech space that need CRM integrations to close enterprise deals but lack the engineering capacity to build and maintain them in-house.

## Frequently Asked Questions

Vessel charges based on the number of connected CRM accounts, making pricing predictable as the customer base grows rather than based on API call volume — aligning cost with the business metric that matters to B2B SaaS companies.

### Does Vessel provide a white-labeled connection flow?
Yes. Vessel's embedded connection UI can be customized with a company's branding so end customers connect their CRM through what appears to be a native integration within the SaaS product, rather than a third-party integration page.
