Case Study · Voice AI / Logistics

Mindel

A Spanish startup building AI voice agents for parcel logistics — virtual receptionists that answer calls 24/7 for GLS and MRW branches, resolving shipment queries, incidents, and pickups end-to-end. Mindel partnered with FlyDevs to design the product, build its AI voice agents, and refactor the entire system — turning a validated product into a platform ready to scale.

Challenges

What we came in to solve

Mindel had already validated its product: AI voice agents answering calls 24/7 for GLS and MRW parcel branches in Spain, with paying clients in production. But the setup that got them there wasn't built to grow — critical parts of the stack were spread across several external contractors, and every change depended on someone else's availability.

The inherited cloud infrastructure was oversized and expensive for what it did, and hard to change without touching everything. With a fragmented market of thousands of independent agencies to win, Mindel needed a technical foundation that could scale from a handful of branches to dozens — without the unit economics breaking along the way.

How we built it

FlyDevs took technical ownership of the platform end-to-end — designing the product experience, building AI voice agents tailored to each client, and refactoring the system so Mindel can onboard new branches without starting over each time.

  • AI voice agents

    multiple voice agents tailored to each client's needs, answering calls 24/7 and resolving shipment queries, incidents, and pickups end-to-end

  • Product & UX/UI design

    product design with a strong focus on user experience, bringing several integrated services together into a single, unified product

  • Centralized stack

    backend, data, and domain brought under a single, owned codebase — no more critical pieces scattered across external contractors

  • Migration to AWS

    moved off an oversized, costly Google Cloud setup to a leaner AWS architecture sized for the workload and ready to grow with it

  • Built for many branches

    a system designed to onboard new parcel agencies — each with its own agent, configuration, and integrations — without custom rework

  • Zero disruption for live clients

    the refactor ran while Mindel's agents kept answering real calls for GLS and MRW branches in production

What we delivered

Mindel now runs on a consolidated, scalable platform it fully controls, with a redesigned product and voice agents built for each client — ready to expand across Spain's parcel network. The migration to AWS ran with zero disruption for live clients: its AI agents kept answering calls 24/7 for GLS and MRW branches throughout. Today the team can ship new features and onboard new agencies at the pace the market demands.

AI voice agents, product design, and full system refactor. Consolidated stack on AWS. Zero disruption for live clients. Built to scale across branches.
