SaaS Development Company in Seattle

What you commission decides the number: a Seattle SaaS MVP at production grade, a Series A scale-up (multi-region, multi-currency, role-based access, customer-managed encryption keys, AppSource or AWS Marketplace listing), or a full enterprise SaaS platform with five-nines targets, customer-deployed connectors, and Microsoft Entra plus Okta plus Google Workspace IdP coverage. Scope drivers include multi-tenant data architecture, Stripe or Maxio billing, SSO and SCIM, admin console, audit logging, and SOC 2 Type II readiness evidence. Seattle rates sit at or near the top of US metros because of the Microsoft, Amazon, and AWS talent premium. We quote fixed-fee.

The Washington My Health My Data Act (MHMDA) took effect on March 31, 2024, and is widely regarded as the strictest US consumer health-data statute. It defines consumer health data broadly enough to capture menstrual tracking, biometrics, location data near healthcare facilities, mental wellness apps, and inferences about health status, and it applies to entities far beyond HIPAA covered entities. It requires affirmative opt-in consent before collection, a separate authorization before sale, a published consumer health data privacy policy, geofencing restrictions around healthcare facilities, and a private right of action under the Washington Consumer Protection Act. Our SaaS engagements run an MHMDA applicability review in discovery, scope consent and deletion flows accordingly, and produce the policy and authorization artefacts your privacy counsel will sign off.

Yes. SOC 2 Type II is table stakes for Microsoft, Amazon, and Bellevue enterprise procurement, and we treat it as a build-time deliverable, not an afterthought. Our SaaS engagements ship with a Drata, Vanta, or Secureframe evidence pipeline wired into the codebase, infrastructure-as-code with tagging that maps cleanly to SOC 2 control families, centralised logging with retention policies that satisfy CC7 monitoring, and access reviews that auto-generate quarterly. We have walked clients through Type II observation windows with auditors from A-LIGN, Schellman, and Prescient Assurance. We do not attest the audit ourselves, but we deliver the evidence and controls so the audit goes smoothly.

Yes. Marketplace and AppSource distribution materially shortens the procurement cycle for any product selling into AWS or Microsoft customers, and the engineering requirements are non-trivial. For AWS Marketplace we wire SaaS Subscription, SaaS Contracts, and the AWS Marketplace Metering API, handle entitlement and metering events, and integrate with the AWS Marketplace seller portal. For Azure AppSource and Microsoft Commercial Marketplace we implement the SaaS Fulfillment API v2, landing page and webhook flows, and Entra ID single sign-on certification. We have shipped against both and can advise on which path fits the buyer ICP. Listings unlock private offer and channel partner motions that Seattle SaaS founders rely on.

We pick the tenancy model deliberately. Pooled tenancy with row-level security in Postgres or DynamoDB is the default for high-volume product-led SaaS where customer counts are large and unit economics dominate. Schema-per-tenant is the right choice when buyers (typically healthcare, life sciences, financial services, or government) require demonstrable data separation. Silo or single-tenant deployments come into scope for Microsoft and Amazon enterprise customers that require customer-managed encryption keys, dedicated infrastructure, or VPC peering. Every model ships with a tenancy isolation test suite that runs in CI, attempting cross-tenant reads on every commit. Findings are recorded in the SOC 2 evidence pipeline and shared with the customer security review on request.

Yes. Microsoft Entra ID (formerly Azure AD), Okta, Google Workspace, OneLogin, and Ping are first-class identity providers on every Seattle build, and SCIM 2.0 provisioning is included as a default rather than a paid tier. We implement SAML 2.0 and OpenID Connect, JIT user creation, group-based role mapping, and the audit hooks Microsoft and Amazon enterprise security reviews ask for. For products selling into Microsoft 365 customers we add Entra ID gallery application certification, which materially shortens the IT admin install path. We also handle the inevitable Okta SCIM edge cases (deprovisioning, group nesting, attribute mapping) that surface late in customer onboarding if they were not designed in early.

AWS us-west-2 sits in Boardman, Oregon, roughly 250 miles south of downtown Seattle, and is the closest AWS region to Washington with general-purpose service availability. Round-trip latency from downtown Seattle to us-west-2 is consistently under five milliseconds, which is indistinguishable from local for almost every SaaS workload. Microsoft Azure customers typically pair Azure West US 2 (Washington) with us-west-2 for cross-cloud failover. We default to us-west-2 because it offers full service coverage including Bedrock, Aurora, and Kinesis, has strong regional disaster recovery options into us-west-1 and us-east-1, and aligns with most Pacific Northwest customer data residency expectations. For Latam expansion we add us-east-1 plus sa-east-1 selectively.

A SaaS MVP (multi-tenant, billing, SSO, admin console, audit log, SOC 2 readiness) runs fourteen to twenty weeks. Week 1 to 3 is discovery, tenancy model decision, and MHMDA plus HIPAA scoping. Week 4 to 6 is design system, data model, and infrastructure-as-code. Week 7 to 16 is build with two-week sprints, gated security scans, and weekly demos. Week 17 to 20 is hardening, SOC 2 evidence wire-up, customer onboarding runbook, and launch. A Series A scale-up adds eight to fourteen weeks for multi-region, customer-managed keys, Marketplace certification, and enterprise IdP coverage. We ship at this cadence consistently and quote fixed-fee.
