Service Overview

SaaS Development Solutions for Seattle Businesses

Seattle defines enterprise SaaS in the United States. Microsoft, headquartered in Redmond, ships the global benchmark stack: Office 365, Dynamics 365, the Power Platform, GitHub Enterprise, and Azure DevOps. Amazon runs AWS Marketplace, Amazon Business, and the Whole Foods partner ecosystem out of South Lake Union, and Tableau (now part of Salesforce) anchors the analytics SaaS category from Fremont. Bellevue and the Eastside add Smartsheet for work management, Concur for travel and expense (now SAP), and DocuSign in downtown Seattle. The sales engineering and revenue intelligence category was effectively invented locally by Outreach and Highspot, both still headquartered in the city. Zillow and Redfin run premier-agent and concierge SaaS for the real estate industry, and the Convoy story (a Seattle freight SaaS that scaled to multibillion valuation before shutdown in 2023) remains a cautionary reference for any local founder. Codazz builds production multi-tenant SaaS for Seattle and Bellevue founders, Series A through Series C operators, and enterprise IT teams who need to ship against this competitive backdrop. Our engineers work PST hours from our Edmonton headquarters and Chandigarh hub, default to AWS us-west-2 (Oregon) for single-digit millisecond latency to downtown Seattle, and deliver the controls Washington buyers now expect: WA My Health My Data Act readiness (the strictest US health-data statute outside HIPAA, in force since March 2024 and applying to consumer apps far beyond covered entities), HIPAA and BAAs where clinical data is involved, SOC 2 Type II and ISO 27001 as table stakes, and Azure parity for any product targeting Microsoft or Microsoft-partner customers. Pricing is USD.

What We Build

SaaS Development Services We Offer in Seattle

Seattle SaaS buyers benchmark against Microsoft, Tableau, Smartsheet, Outreach, and Highspot, not against templated multi-tenant boilerplate. Our SaaS development service is built to that standard. We design multi-tenant data architectures (schema-per-tenant, row-level security, or hybrid), build TypeScript or Go services with typed APIs in tRPC, GraphQL, or OpenAPI, and ship admin consoles, billing, and entitlement systems that integrate with Stripe Billing, Maxio (formerly Chargify), and Microsoft Commerce when AppSource or Marketplace listings are in scope. Every product ships with an audit log, SOC 2 evidence pipeline, role-based access aligned to common Microsoft and Okta IdP patterns, and a tenancy isolation model your security review can defend. For Washington-resident user data we map the My Health My Data Act early, because retrofitting consent and deletion flows after launch is materially more expensive than designing them in.

Industry Expertise

SaaS Development for Seattle's Key Industries

Seattle SaaS demand concentrates in four verticals and we have shipped in each. In enterprise productivity and work management, Smartsheet, Microsoft, and Asana (Bay Area but heavily Seattle-staffed) have set the bar on collaboration, permissioning, and admin consoles. In sales engagement and revenue intelligence, Outreach, Highspot, and Gong have defined sequencing, content management, and conversational analytics, and our pattern work mirrors their multi-tenant approach. In real estate technology, Zillow Premier Agent and Redfin Concierge run high-volume SaaS for agents and brokerages, with lead routing, IDX integration, and territory entitlement models we have built variants of. In cloud-adjacent IT and developer tools, GitHub Enterprise, Azure DevOps, and Concur (SAP) have raised expectations on SCIM, audit, and enterprise admin. We also serve UW Allen School spinouts, Bellevue and Kirkland startups inside the Microsoft for Startups program, and Latam-adjacent SaaS targeting Microsoft AppSource distribution.

Our Process

Our SaaS Development Development Process

Discovery, design, build, and launch run on PST hours so Seattle and Bellevue product leads get synchronous standups, not overnight handoffs. Discovery opens with a tenancy model decision (single-tenant vs pooled vs hybrid), a SOC 2 Type II readiness review, and a Washington My Health My Data Act applicability scoping pass that determines whether any data the product touches qualifies as consumer health data under the statute's broad definition. For builds targeting Microsoft customers we add an Azure Marketplace and AppSource certification path. Build sprints are two weeks with security scans (Snyk, Semgrep) and infrastructure-as-code reviews gated in CI. Launch includes a documented onboarding runbook, a tenancy isolation test report, and a privacy notice aligned with My Health My Data, HIPAA where applicable, and the Washington Consumer Privacy Act considerations the legislature is actively debating.

Technology

Technologies We Use for SaaS Development

We default to AWS us-west-2 (Oregon) for production, which Microsoft Azure customers in Redmond and Seattle generally pair with US West 2 (Washington) for failover. AWS us-west-2 sits in the Pacific Northwest power and latency band that Codazz pitches as Seattle-adjacent, with sub-five-millisecond round trips into downtown. Backends run on Node, Go, or Python on EKS or ECS Fargate, with Postgres on RDS or Aurora Serverless v2, Redis on ElastiCache or Upstash, and event streams on Kinesis or MSK. Frontends are Next.js or Remix on Vercel or AWS Amplify. Identity is Okta, Microsoft Entra ID (formerly Azure AD), or Auth0 with SCIM provisioning. Observability is Datadog, Honeycomb, or the Microsoft stack (Application Insights plus Log Analytics) when the buyer is a Microsoft house. CI is GitHub Actions for Marketplace alignment, GitLab when the buyer prefers it.

Why Choose Us

Why Seattle Businesses Choose Codazz for SaaS Development

We combine world-class engineering with local market understanding to deliver saas development solutions that drive real business outcomes.

🪟

Microsoft and Azure Native

Seattle SaaS often sells into Microsoft or Microsoft-partner customers. We ship Entra ID gallery certification, Microsoft Commercial Marketplace SaaS Fulfillment API v2 integrations, AppSource listings, and Azure parity for any product where the buyer expects it. Outreach, Highspot, and Smartsheet have set the Microsoft-integration bar locally.

🛒

AWS Marketplace Listings

AWS Marketplace and AWS Marketplace Metering API integration is included as a build-time deliverable for Series A and later SaaS, with SaaS Subscriptions, SaaS Contracts, and private offer support. Marketplace listings materially shorten enterprise procurement for products selling into Amazon Business and AWS customers.

🩺

My Health My Data Ready

The Washington My Health My Data Act (in force March 2024) is the strictest US consumer health-data statute and reaches far beyond HIPAA covered entities. Every engagement runs an MHMDA applicability review in discovery and ships the consent, authorization, geofencing, and policy artefacts your privacy counsel signs off.

📜

SOC 2 and ISO 27001 Wired In

SOC 2 Type II and ISO 27001 are baseline for Bellevue and Seattle enterprise procurement. Builds ship with a Drata, Vanta, or Secureframe evidence pipeline wired into the codebase, infrastructure-as-code tagged to control families, and a tenancy isolation test suite that runs on every commit.

📍

Frequently Asked Questions About SaaS Development in Seattle

Have a question not listed here? Reach out to our team and we will get back to you within 4 hours.

Ask a Question

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.
