Client video testimonial
Guliver Kalamba runs MeisterFlow for Swiss home-service operators. FusionSync built the multi-tenant booking, invoicing, and SEO platform he ships today on app.meisterflow.ch.
Building a SaaS platform is challenging. Shubham consistently came up with smarter, more scalable solutions and was always thinking several steps ahead.

Who this is for
You sell (or want to sell) AI, automation, or software services to businesses. Maybe you already have clients asking for things you cannot build in-house. Maybe you are packaging a new technical offering and need a delivery partner. Either way, the gap is the same: your clients need technology, and you need someone to build it under your brand.
Whether you have paying clients today or you are building your first offer, the model works. What matters is that you can get a business to say yes.
Your clients ask for AI solutions, automations, or integrations you do not have the team to build. That gap limits what you can sell.
One client is a project. Three or more in the same space is a partnership. The model gets better as you grow.
Dental, insurance, real estate, creator economy, or any vertical where you know the pain points. We build the tech. You guide where it connects.
Best fit: agencies with at least one client or a clear sales pipeline in a specific market.

Agencies that sell or want to sell AI and automation services
You did not start your agency to become a software company. You started because you are good at getting clients results. Whether you already have clients asking for technical work or you are building that offering now, the gap is the same: someone needs to build, deliver, and support the technology under your brand. That is what we do.
Phase 1
We build a working demo scoped to your vertical and client type. It runs on GoHighLevel, n8n, and the integrations your market needs. Not custom software yet. You pitch it to your prospects or existing clients. One free POC per vertical. Your next free POC unlocks after your first ownership milestone (25 active clients).
Phase 2
Implementation starts only after a client is paying you. Same productized tiers as standalone: simple, mid-complexity, or full stack. Early clients stay on the proven stack so delivery stays fast and consistent. Volume discounts apply to monthly support as your active client count grows.
Phase 3
Once the model works across your base, we build production-grade software under your brand: auth, billing, tenant isolation, and UI your clients see as yours. You focus on growing the client base. We handle architecture, build, and migration from the stack path.
While you scale in one geography, we can replicate the same playbook with a new local partner in the next market.
As your active client base grows, you earn the right to own the software. Ownership is optional at each milestone. You can stay on the recurring model indefinitely.
25 active clients
Own the software for your geography and vertical plus tech stack combination. FusionSync will not build the same solution for competitors in your geography. Transfer fee: $5,000 optional.
We step back from that geography for this vertical.
100 active clients
Own the software globally for your vertical plus tech stack combination. Battle-tested product with a proven client base, not just code. Transfer fee: $15,000 optional.
We replicate the model in the next market with a new partner.
Two clean paths after ownership (or anytime you prefer fulfilment over hiring). Most partners keep Path A because ops is the hard part to staff.
Path A
FusionSync stays on as your invisible tech partner. We maintain the product, handle updates, infrastructure, and scaling. Per-client recurring continues plus a product maintenance fee (baseline $500/month, scoped to complexity).
Path B
Full documentation, codebase handover, and training sessions included in the transfer fee. Clean exit with no ongoing obligation. Additional training at $40/hour.
Either way, you walk away with a tech layer inside your agency that your competitors cannot match.
