How SiftHub layered enterprise auth on top of their stack

SiftHub is an AI-native platform helping sales and presales teams move faster and close more. It acts as an always-on teammate that understands product architecture, answers technical questions, and handles RFPs, security reviews, and stakeholder asks throughout the sales cycle.

Customers like Congruent, Allego, Outsourcing, and Superhuman use SiftHub to drive deal velocity across their teams.

As enterprise demand picked up, so did expectations around IT compliance and identity integration. Enterprise buyers required SAML-based SSO, SCIM provisioning, and clean directory sync, often as a prerequisite before a deal could even move forward.

The challenge: scaling identity without slowing down

SiftHub had already built a solid foundational auth system in-house. It covered core authentication needs and worked well for early customers.

But as enterprise prospects grew in volume and complexity, so did the lift required to meet their identity requirements. Supporting SSO integrations manually and managing access at scale were starting to take engineering time away from product development.

Rather than expand their internal system to handle SAML and SCIM use cases, the team chose a better path: integrate Scalekit’s drop-in enterprise auth stack.

“We started with a strong internal auth foundation, but we knew we didn’t want to reinvent SSO and SCIM. Scalekit gave us a full enterprise auth layer that just works—and let us stay focused on our roadmap.”

The rollout with Scalekit

Scalekit plugged in cleanly on top of SiftHub’s existing infrastructure, no rewrites, no re-architecture. The team progressively layered in enterprise-grade auth features without disrupting their roadmap.

• SSO integration (SAML and OIDC)Support for both SAML and OIDC-based SSO across identity providers like Okta, JumpCloud, and Google Workspace, including both SP and IdP-initiated login flows
  ‍
• SCIM provisioning with role mapping
  Automated user lifecycle management through customer directories, including onboarding, deactivation, and group-based role assignments mapped directly to SiftHub’s internal access tiers

• Embedded admin portal
  A self-serve interface for customers to configure and manage their own SSO and SCIM connections, reducing support effort and accelerating onboarding

“Enterprise auth was starting to hold up deals. With Scalekit, we were able to ship SSO and SCIM quickly and move upmarket without slowing our team down. It let us stay focused on what matters—delivering product value.”
