“Promptapp engineered our multi-tenant SaaS with token-based Stripe metering from scratch. We scaled to $80k MRR in four months with zero downtime.”
Nathan Cole
Founder & CEO, CopyPulse AI
Turn your AI models into a scalable, high-margin subscription business. We architect, build, and deploy multi-tenant AI SaaS platforms with usage-based billing, enterprise tenant isolation, and sub-second streaming inference.
A proven engineering path from multi-tenant data architecture to automated Stripe revenue operations.
We architect database partitioning, isolated tenant schemas, model inference routing, and pricing tier logic.
We build streaming frontend UIs, background AI processing queues, user auth, and real-time Stripe token metering.
We engineer multi-seat team management, role-based access, API key provisioning, and automated user onboarding flows.
We deploy on auto-scaling cloud GPU/CPU clusters with rate limiters, telemetry logging, and automated billing reconciliations.
Every AI SaaS platform we architect is designed for high customer retention, defensible unit margins, and enterprise security.
Strict data segregation between tenant accounts—ensuring zero data leakage across organization workspaces and customer accounts.
Granular token, credit, and API call tracking synced directly with Stripe for transparent, profitable, and automated usage billing.
Decoupled background task architectures so heavy generative AI jobs execute smoothly without freezing your user interface.
Enterprise-ready encryption, immutable audit trails, role-based permissions, and GDPR data retention policies out of the box.
Most software agencies fail at AI latency, and AI consultants don't understand SaaS unit economics. We excel at both:
Flexible engagement models designed for bootstrapped founders, venture-backed startups, and enterprise SaaS divisions.
A full agile product pod focused on shipping a complete, revenue-generating multi-tenant AI SaaS with billing and auth in 6 to 8 weeks.
An ongoing dedicated cross-functional team adding enterprise B2B features, custom integrations, SAML/SSO, and low-latency API optimization.
Senior full-stack SaaS developers and MLOps engineers integrated into your sprint cycles to unblock core architecture bottlenecks.
Comprehensive engineering covering every technical layer required to run a scalable, profitable AI software business.
Schema-per-tenant, isolated customer datastores, or row-level security ensuring impenetrable data isolation and compliance across accounts.
Token meters, prepaid credit wallets, tiered subscription packages, and automated webhook reconciliation integrated via Stripe Billing.
Real-time token streaming via Server-Sent Events (SSE) alongside robust background job queues (Redis / Celery) for long-running batch jobs.
Multi-seat team organization hierarchy, granular permission levels, seat allocations, domain-level team invites, and administrative oversight.
Public REST and GraphQL API gateways, personal access key management, rate limiters, and comprehensive developer documentation.
Cost-optimizing fallback routers dispatching simple queries to fast lightweight models while reserving expensive frontier LLMs for complex tasks.
Automated SSL certificate provisioning, custom domain routing, and dynamic tenant theme engines for B2B enterprise white-labeling.
Real-time monitoring of per-tenant margin profitability, API response latency, model error rates, and automated drift alerts.
Our operational track record across commercial AI SaaS platforms powering global subscriptions:
Real feedback from SaaS founders and CTOs who trusted us to engineer their multi-tenant cloud platforms.
“Promptapp engineered our multi-tenant SaaS with token-based Stripe metering from scratch. We scaled to $80k MRR in four months with zero downtime.”
“Their model routing architecture cut our inference server bill by 62%. Our gross margins improved overnight without sacrificing quality.”
“We closed our first Fortune 500 contract because Promptapp's team had built SAML/SSO and strict tenant isolation into our SaaS from day one.”
