SEI delivers end-to-end technology, operations, and asset management solutions to asset managers, banks and wealth managers, financial advisors, and institutional investors. Marquee platforms include the SEI Wealth Platform (front-to-back wealth management technology and outsourced operations), SEI Data Cloud (managed near-real-time data platform), SEI Sphere (managed IT, cybersecurity, cloud, and network operations), and SEI Novus (institutional portfolio analytics). SEI does not run a public developer portal — partner and client integrations are delivered through contractual onboarding to the SEI Wealth Platform, SEI Connect advisor channels, and managed-service engagements rather than self-serve OpenAPI or SDK distribution. created: '2026-05-23' modified: '2026-05-23' specificationVersion: '0.19' apis: [] x-no-public-api: true x-no-public-api-reason: >- SEI Investments does not publish a public developer portal, OpenAPI specifications, SDKs, sandbox environments, or self-serve API keys. The SEI Wealth Platform, SEI Data Cloud, SEI Sphere, SEI Novus, and SEI Access for CITs are delivered to institutional clients (banks, RIAs, asset managers, pension plans) under contract, with integrations arranged through SEI onboarding, professional services, and partner programs. There is no developer.seic.com, api.seic.com, or public GitHub organization for SEI as of this profiling. The "SEI Connect" naming sometimes referenced in advisor partner contexts is not a public API product with documentation or specifications available outside contractual relationships. common: - type: DomainSecurity url: security/sei-investments-domain-security.yml - type: Website url: https://www.seic.com/ - type: AboutUs url: https://www.seic.com/about-sei/overview - type: AssetManagersOverview url: https://www.seic.com/asset-managers/overview - type: BanksAndWealthManagersOverview url: https://www.seic.com/banks-and-wealth-managers/overview - type: FinancialAdvisorsOverview url: https://www.seic.com/financial-advisors/overview - type: InstitutionalInvestorsOverview url: https://www.seic.com/institutional-investors/overview - type: Blog url: https://www.seic.com/insights - type: Newsroom url: https://www.seic.com/about-sei/newsroom - type: InvestorRelations url: https://ir.seic.com/ - type: Careers url: https://careers.seic.com/ - type: Locations url: https://www.seic.com/about-sei/locations - type: ContactUs url: https://www.seic.com/about-sei/contact-us - type: Login url: https://www.seic.com/ent/client-site-logins-and-contact-information - type: PrivacyPolicy url: https://www.seic.com/ent/privacy-notice - type: TermsOfService url: https://www.seic.com/ent/terms-use - type: CookiePolicy url: https://www.seic.com/ent/cookie-policy - type: AccessibilityStatement url: https://www.seic.com/ent/accessibility-statement - type: CodeOfConduct url: https://www.seic.com/ent/code-conduct-and-corporate-governance - type: LinkedIn url: https://www.linkedin.com/company/sei-investments-company/ - type: Sitemap url: https://www.seic.com/sitemap.xml - type: Robots url: https://www.seic.com/robots.txt platforms: - name: SEI Wealth Platform description: >- Modern, fully integrated wealth management technology and outsourced operations solution used by banks, trust companies, and wealth managers.
