At FusionSync AI, you'll work directly with me (Shubham), the lead engineer behind every project. I personally architect and build every AI SaaS platform we deliver, from MVPs to production-ready multi-tenant systems.
Our agency exists to provide additional design, QA, and support when it adds value, but you'll never be handed off to a junior developer or sales representative. Every project is engineered for production, not just a working demo.
➤ How We Work With Clients
→ For Founders & Direct Businesses:
We build your core product. From database schema and secure authentication to advanced RAG pipelines and custom API integrations, we architect systems that hold up with real users and scale efficiently from day one.
→ For Agencies:
You have the clients and the vertical expertise. We provide the invisible technical infrastructure. We help you validate demand with GHL/n8n workflows, handle the technical fulfillment of complex AI voice agents, and eventually build the proprietary white-label SaaS you sell under your own brand. We stay invisible. You stay the face.
→ Why We're Different: Agent-Managed Engineering
We run our full delivery pipeline through AI agents. Architecture design, sprint planning, workflow generation, and system integration happen inside IDEs via Claude Code and Cursor, tuned for production-grade output at every stage.
➤ What We Build
→ AI SaaS Products: full-stack, multi-tenant, subscription and billing-ready
→ Agentic Voice & Chatbot Platforms: autonomous agents that handle real conversations end to end, not scripted flows
→ AI Sales & Support Agents: qualify, follow up, book, and close across web, voice, SMS, WhatsApp, and email
→ Multi-Tenant Platforms: booking, invoicing, and client management built for real business operations
➤ Best Fit For
→ Founders who need a working MVP, not a spec doc
→ Startups needing a technical partner that moves fast
→ Businesses needing custom internal software: booking, invoicing, multi-tenant systems
→ Teams burned by slow agencies or all-talk dev shops
→ Anyone needing an AI sales agent that books appointments and closes
