B2B SaaS platforms engineered for high-margin recurring revenue.
We design and build multi-tenant cloud software ecosystems that scale from day-one launch to millions in annual recurring revenue. Featuring automated self-service provisioning, Stripe/Paddle billing pipelines, SAML SSO, and strict Row-Level Security, we engineer SaaS products ready for enterprise procurement.
Engineering for recurring software economics.
Building a Software-as-a-Service product requires far more than creating an interface with a login screen. It requires an entire business operating system: automated account provisioning, metered billing synchronizers, role-based access control, tenant data isolation, and comprehensive customer self-service.
SYSCON engineers SaaS backends that turn complex enterprise workflows into frictionless digital subscriptions. We eliminate manual engineering bottlenecks so your business can onboard hundreds of new commercial accounts every month with zero human intervention.
Why high-valuation businesses build SaaS ecosystems.
Moving from one-off transactional services to scalable software subscriptions transforms corporate enterprise valuation.
Predictable Monthly ARR
Compound recurring revenue month-over-month with automated renewals, expansion revenue tiers, and low customer churn rates.
Self-Service Expansion
Account administrators add seats, purchase additional API quotas, and upgrade plans seamlessly inside the product without sales reps.
Enterprise Upmarket Readiness
Command six-figure enterprise contracts by delivering SAML SSO, audit logging, custom contracts, and SOC2 compliance out of the box.
Capital Efficient Operations
Shared database resources and microservice auto-scaling keep infrastructure server costs below 12% of top-line subscription revenue.
Real-Time Product Telemetry
Track feature adoption, user drop-off points, and daily active users (DAU) automatically, informing data-driven roadmap prioritizations.
Global Multi-Currency Billing
Accept 135+ currencies with automated tax calculation (VAT / Sales Tax) via Stripe Tax, expanding your customer base worldwide.
Enterprise engineering capabilities for SaaS platforms.
We design software architectures that handle complex billing logic, tenant lifecycle management, and high-concurrency requests.
Metered Billing Engine
Hybrid subscription models combining seat licenses with metered API calls, storage gigabytes, and transaction percentages synchronized with Stripe.
Row-Level Security
Strict PostgreSQL RLS policies preventing tenant data crossover at the database query engine layer with zero risk of developer oversight.
Enterprise SAML & SCIM
Single Sign-On integration with Okta, Microsoft Entra ID (Azure AD), and Google Workspace with automated employee directory synchronization.
Feature Flagging & Tiers
Dynamic capability gates that enable or restrict enterprise features based on the tenant’s active subscription tier without code redeployments.
Interactive SaaS subscription & revenue modeler.
Adjust seat counts, metered API tiers, and enterprise add-ons to simulate how your SaaS billing pipeline calculates Monthly Recurring Revenue (MRR) and gross margins.
Multi-tenant data isolation: Pooled vs Siloed architectures.
Data security in SaaS is non-negotiable. If customer A ever sees customer B’s private financial records or customer lists, trust is destroyed and company valuation collapses.
We engineer multi-tenant systems using PostgreSQL Row-Level Security (RLS) and schema isolation. Every single query automatically appends the cryptographic tenant scope at the database connection layer, guaranteeing complete logical separation with pooled resource cost efficiency.
Defense-in-depth security ensures application-layer bugs cannot bypass PostgreSQL-enforced tenant boundaries.
Win Fortune 500 accounts with enterprise authentication.
Enterprise procurement teams reject SaaS tools that do not integrate with corporate identity providers. We build the features your enterprise champions need to pass IT review.
SAML 2.0 & OIDC Single Sign-On
Allow enterprise employees to log into your SaaS using their corporate Okta, Microsoft Entra ID (Azure AD), Google Workspace, or PingFederate accounts securely.
SCIM 2.0 Directory Sync
Automated user provisioning and de-provisioning. When an employee is removed from the corporate HR system, their SaaS account access is revoked immediately.
Custom Subdomain & CNAME Routing
Allow enterprise tenants to access their workspace via customized URLs (e.g., portal.acmecorp.com) with automated Let's Encrypt SSL certificates.
Simulate automated self-service tenant provisioning.
Enter a sample organization name and trigger the automated provisioning sequence to inspect the database, caching, and billing steps that execute in sub-second time.
Event-driven asynchronous messaging with Kafka and Redis.
A common reason early-stage SaaS platforms crash when scaling is coupling heavy operations (such as generating 500-page PDF reports or running machine learning classifications) to synchronous HTTP requests.
We engineer decoupled architectures where user interactions dispatch lightweight event payloads into Apache Kafka, RabbitMQ, or AWS SQS. Dedicated stateless worker pools consume messages asynchronously, ensuring your web and mobile apps respond in under 50ms at all times.
SOC2 Type II & ISO 27001 readiness built into code.
Passing enterprise vendor security questionnaires requires verifiable proof of operational controls. We engineer SaaS platforms to meet compliance benchmarks from day one.
Automated Compliance (Vanta)
Infrastructure code aligned with Vanta and Drata continuous monitoring, verifying AWS/GCP encryption, MFA enforcement, and access controls.
AES-256 Envelope Encryption
Every tenant's sensitive API tokens and PII data are encrypted with unique per-tenant keys managed via AWS KMS or HashiCorp Vault.
Immutable SIEM Audit Logs
Tamper-proof event logs forwarded directly to Datadog or AWS CloudWatch with cryptographic verification for compliance audits.
Zero-Trust API Perimeter
Strict API token rate-limiting, IP allowlisting for enterprise workspaces, and DDoS protection via Cloudflare Magic Transit.
99.99% availability with automated multi-zone failover.
When enterprise customers rely on your SaaS to run their day-to-day operations, downtime directly damages their business and triggers costly SLA penalties.
We engineer SaaS infrastructures deployed across multiple cloud Availability Zones with automated health checks, read-replica database failover, and continuous snapshot backups, achieving Recovery Point Objectives (RPO) under 60 seconds.
