    fylt Dashboard is the studio command center that brings your client pipeline, project status, multi-currency revenue, and support metrics into one customizable, real-time view — so you always know where your business stands without checking multiple tools.
  • CRM
    fylt CRM is the client relationship hub built for service businesses — it tracks leads through a visual pipeline, organizes each client's projects, invoices, and contracts in one profile, and collects testimonials, replacing the need for a separate customer-relationship-management tool.
  • Calendar
    fylt Calendar is the scheduling and booking module that syncs with Google Calendar and Microsoft Outlook, converts time zones automatically, and lets clients book available slots directly — replacing a separate online scheduling app.
  • Projects
    fylt Projects is the visual project management module — a drag-and-drop Kanban board that tracks tasks, deadlines, and billable hours, with granular controls over what clients see in their portal, replacing a standalone project tool.
  • Billing
    fylt Billing is the invoicing module — it turns quotations into invoices, tracks partial and installment payments you record, logs expenses with billable linkage, and converts every currency automatically at live rates across 60+ currencies. Clients pay you directly; fylt records those payments and shows payment instructions on each invoice.

    fylt Storefront is the module that publishes a branded, search-optimized public page showcasing your services and portfolio, with a built-in booking widget that captures new leads directly into your CRM.

What's the story behind your product?

fylt.app's answer

fylt started with a simple observation: running a service business often means stitching together a CRM, calendar, project management tool, invoicing software, contract tool, file storage and client communication platforms.

Each tool solves a specific problem, but the client journey becomes fragmented across all of them.

fylt was created to bring those workflows together into one connected system — so service businesses can spend less time managing software and more time managing their clients and delivering their work.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

Who are some of the biggest customers of your product?

fylt.app's answer

fylt is currently growing its customer base and does not publicly disclose individual customer names at this stage.
