Marketplace Software We Design and Build

Why Z-Axiss

Why Marketplaces Choose Z-Axiss

01

Humans Stay Accountable

Our agents draft messages, summaries and offers, but nothing binding goes out without a person’s approval. Every AI suggestion is shown as a proposal, with its evidence.

02

Both Sides Designed

Buyers and sellers, providers and customers want different things from the same platform. We design each side from its own job, then design the handovers between them.

03

Sensitive Documents Protected

Financial statements and contracts get role-based access, controlled sharing and full audit trails, built on OWASP guidelines and GDPR principles from the first sprint.

04

Agentic AI Depth

We engineer multi-agent systems on Google ADK, LangGraph and the OpenAI Agents SDK, with tracing, cost tracking and evaluation, so you can see what every agent did.

05

Multi-Tenant Foundations

Operators, partner firms and their teams need seats, roles and billing that scale. We build organization hierarchies where admins see everything and users see only their own work.

06

You Own Everything

Your code, agent definitions, evaluation sets and data stay yours, with NDAs and IP assignment as standard. Models sit behind a swappable interface, so there is no lock-in.

Ask a Question

We usually start with an 8-week MVP: one side posting listings, the other discovering and responding, plus one agent workflow such as ranking or document summaries. A full two-sided platform with organizations, billing, secure document sharing and mobile apps typically runs as a phased program over several months. We plan in milestones so you see working software every sprint and can put real users on it early.

We follow four stages: discover, prototype, evaluate, deploy. Discovery maps your deal flow and marks every step involving money, legal terms or sensitive documents. Agents then take the routine work around those steps, such as search, matching, summaries, drafting and scheduling. Anything binding, such as an offer or contract, waits for a person’s approval. Every run is traced and evaluated, so you see what each agent did and why.

Cost depends on how many sides and roles the marketplace has, how many agents it needs, the documents it must read, and integrations such as payments, e-signature, calendars and listing sources. Web plus mobile, multi-tenant billing and compliance needs also shape the effort. We scope each build in detail and give you a fixed quote. Book a free 30-minute call to get yours.

We have designed AI agents for a business-sales marketplace, and two-sided platforms that match supply with demand and handle pricing and payments. Since 2018 we have served 15+ clients with one team of engineers and designers. You own all code and IP, and you get working software every sprint, plus support after launch.
