We design and engineer AI-native SaaS products for founders and enterprises in Noida and Delhi NCR — from LLM-powered core features to subscription billing, multi-tenant architecture, and GTM-ready infrastructure.
Web Development Service #8 / 58
Building an AI SaaS product is more than picking a model API. It requires a multi-tenant architecture that isolates customer data, a subscription engine that handles trials and upgrades, and AI features that remain accurate and cost-efficient at scale. We build all of it.
Marketing Wise has delivered 18+ AI SaaS products since 2022 — HR automation tools, legal document platforms, marketing intelligence products, and customer analytics tools for founders and enterprise teams in Noida, Delhi, and Gurugram. Each product ships with multi-tenant data isolation, subscription management, and usage-based AI cost controls.
We design the AI feature architecture to be accurate, observable, and cost-managed. LLM calls are routed intelligently — expensive models for complex reasoning, cheaper models for routine extraction — keeping AI API costs from crushing margins as usage scales.

No mystery phases. Four gates every AI SaaS engagement crosses — from product architecture to GTM launch.
We map the full product: user roles, multi-tenant data model, AI feature scope, model selection, and subscription plan structure. Architecture is documented and signed off before a line of code is written.
Multi-tenant database with row-level security, authentication, team workspaces, and subscription billing are built and tested. The product skeleton is live in a staging environment by the end of this phase.
LLM features are integrated with model routing, RAG pipelines, usage metering, and output validation. Prompts are calibrated on real data, cost per operation is benchmarked, and AI output quality gates are set before opening to beta users.
Onboarding flow is finalised, load testing is run, monitoring and alerting are configured, and the product is handed over with runbooks. We support the first 30 days post-launch as standard.
Launched in 18 weeks. 400 paying customers in first 3 months. AI generation cost held below ₹0.80 per JD at scale.
The founder had a validated market for AI-generated JDs but needed a multi-tenant product with trial, subscription, and team plan management — not just an LLM wrapper. Previous developer had failed to deliver after 6 months.
We rebuilt the product architecture from scratch: multi-tenant PostgreSQL, GPT-4o for generation, Claude Haiku for editing, Razorpay subscription billing, and a team workspace model. Shipped to beta in 14 weeks.
Next.js, Node.js, PostgreSQL, GPT-4o, Claude Haiku, Razorpay, Resend
Reduced lawyer review time per contract by 62%. First 50 law firm customers acquired within 4 months of launch.
Junior lawyers at the target law firms spent 3–4 hours on each NDA and service agreement review. The founder needed a product that extracted clauses, flagged non-standard terms, and suggested redlines in lawyer-comprehensible language.
We built a multi-tenant contract analysis platform: PDF/DOCX ingestion, clause extraction with structured schema, GPT-4o reasoning for risk flagging, tracked-changes redline generation, and a comment thread interface for lawyer collaboration.
React, FastAPI, PostgreSQL, GPT-4o, Python-docx, AWS S3, Stripe
Onboarded 120 agency clients in first 6 months. Net revenue retention at 114% after 6 months.
Marketing agencies were manually tracking competitor content, ad campaigns, and positioning for each client. The founder needed a product that automated this across 50+ signal sources per client and surfaced insights weekly.
We built a multi-tenant intelligence platform that crawls competitor websites, social channels, and ad libraries, runs LLM analysis for positioning changes and content themes, and generates weekly briefing reports sent automatically to the agency and end client.

"They delivered our platform in 12 weeks, on budget and exactly to spec. Weekly demos kept us informed at every stage and the final product matched the requirements document line by line."
"The API architecture they designed handles our peak load without breaking a sweat. We have had zero downtime in eight months of production. The codebase is clean, documented, and our internal team can extend it independently."
"We evaluated three development agencies before choosing Marketing Wise. Their scoping process was the most rigorous — they produced a requirements document that found two gaps we had not identified ourselves."
"The backend they built scaled from 500 to 15,000 daily active users in six months without a single architecture change. That kind of headroom built into the design is rare from an agency engagement."
"Post-launch support was exceptional. They flagged and fixed two edge cases we had not anticipated within 24 hours. The handover package — source code, infra docs, runbook — meant our team could take ownership immediately."

Yes. We sign NDAs before any discovery conversation. All code, data models, and proprietary prompts are your IP. We do not reuse client-specific architecture or training data across projects.
We integrate Razorpay for India-first products — supporting UPI, cards, net banking, and international payments. For global products, we integrate Stripe with regional tax handling. Both support trial periods, plan upgrades, proration, and webhook-driven entitlement updates.
We advise on model selection based on your task type, latency requirement, and cost tolerance. We benchmark candidate models on your actual data before committing to an architecture. This prevents expensive switches mid-build when a model underperforms in production.
