From trade routes to tech stacks, marketplaces fuel connection
From ancient bazaars to today’s online platforms, marketplaces have always connected people, ideas, and resources. Marketplaces can play a key role in opening closed systems and supporting efficient and equitable processes by creating an environment where multiple sellers, buyers, and users can interact — and where communities, regions, and resources that may otherwise be confined to certain networks or operating in isolation can connect. They can even be catalysts for societal transformation by driving competition, innovation, and the open exchange of information and ideas.
With the internet, the power of marketplaces has naturally moved online, becoming the internet’s bazaars for buying and selling not only physical goods (e.g., Amazon, Etsy, Craigslist) and services (e.g., Upwork, Fiverr) but also digital products (e.g., Apple’s App Store, Google Play Store, Microsoft App Store), creating a world of opportunities for innovation.
In this section, we talk about a notable evolution within the marketplace space — the rise of software-specific add-on marketplaces, which make it easier for utilities to find, build, and deploy specialized tools that extend core platforms, solve real operational challenges, and speed up digital transformation.
Marketplaces are where innovation connects to the mainstream — by unleashing ideas that resonate with people, their problems, and desire for a better tomorrow.

What are software add-on marketplaces & how can they benefit water?
Software add-on marketplaces allow users to extend and build on top of a core software platform, then list those add-ons, apps, plugins, extensions, or integrations for sale (or for free). Sometimes called “B2B app marketplaces,” “integrations marketplaces,” or “partner marketplaces”, industries like design, marketing, geographic information systems (GIS), and customer relationship management (CRM) have already embraced this new step in the evolution of the marketplace. The ArcGIS marketplace, SalesForce’s AppExchange, and HubSpot App Marketplace are all good examples.
At the heart of add-on marketplaces lies the core software platform that supports those add-ons, providing the essential infrastructure for their operation. APIs (Application Programming Interfaces) and SDKs (Software Development Kits) offered by the hosting software company serve as critical tools that enable third-party developers to interact with the core software and create new functionalities. APIs act as the building blocks facilitating this interaction, while SDKs provide the necessary resources and tools for developing applications and extensions.
By offering these resources, software companies enable developers to extend the software’s capabilities, ensuring their creations integrate seamlessly into the broader ecosystem. This foundational support is what makes these add-on marketplaces dynamic hubs of innovation.
The result is an open, evolving ecosystem where new capabilities can be created and shared using existing tools and knowledge, and building on what already works. Users get customized tools. Developers get visibility, revenue, and feedback. Platforms grow stronger through community-driven innovation.
While these marketplaces have been successful in helping other industries foster collaboration and accelerate progress, the water industry software sector is only just starting to take advantage of its benefits and the opportunities it holds for the Open Water approach. For the water sector, embracing this model could mean faster innovation, stronger collaboration, and more responsive solutions — built not just by vendors, but by the community itself.
A marketplace mindset in water: The Australian example
While digital marketplaces may be new to the water sector, the value of marketplace thinking isn’t. Australia’s water trading framework is a good example of a marketplace mindset applied to water resource management.
Recognized around the world as pioneering water reform, Australia began to unbundle water rights in the 1990s — most notably by separating water entitlements from land ownership. This reform enabled water allocations to be bought and sold independently of property.
This paved the way for water allocations to be more flexible and traded with clear economic value. The system aims to manage water in a way that optimizes economic, social, and environmental outcomes, by ensuring water resources are more efficiently shifted between competing demands and directing them towards their highest-value uses, whether that’s productive activities or environmental conservation.
It’s a physical marketplace for water itself, not software. But the principle is the same: open up access, enable participation, and let value flow to where it’s needed most.
6 benefits of software add-on marketplaces in the water sector
By opening up their platforms and creating opportunities for collaboration, software companies can help the water sector move faster, adapt more easily, and solve bigger challenges together. Here are six key ways add-on marketplaces can create real value for utilities and the broader water community.
1. Closes the gap between technology and real-world applications
A persistent challenge in the water sector is the disconnect between cutting-edge technology and its practical application for utilities of all sizes and capacities. Every water utility operates within a distinct set of parameters. Infrastructure size, local topography and geography, local regulations, in-house expertise, and budget constraints mean each utility needs technology they can tailor to their operational reality.
With robust core software to build on, and APIs, SDKs, and an add-on marketplace to share creations, developers, enthusiasts, and water experts can help close the gap between technology and real-world applications. They can create and share specialized solutions that target and solve the challenges they see and experience in their daily work. An open platform combined with an add-on marketplace creates an environment where the user experience is prioritized and solutions are personalized, allowing water utilities to find precise solutions that fit their needs, and helping to solve high-impact problems.
2. Democratizes access to custom tools and integrations
Software add-on marketplaces can help democratize access to advanced tools, integrations, and markets in the water industry, leveling the playing field and ensuring that innovation benefits the entire sector, not just the largest players.
With open APIs and SDKs, anyone with the desire can create discrete tools or enhancements that plug into the core system and make them available to others — often at a fraction of the cost of large-scale software implementations.
This can lower barriers to market entry and empower independent developers and small companies to innovate, monetize their expertise, and contribute meaningfully to the water utility sector’s digital transformation.
Utilities of all sizes and capacities benefit from this innovation without bearing the full cost of development but still gaining access to a wide range of digital tools that fit their budgets and needs. They can customize their core software without overhauling their entire digital infrastructure, helping to ensure that innovation in the water sector is not limited to a select few but accessible to all.
3. Empowers software ecosystems & interoperability
Add-on marketplaces can help incentivize a software ecosystem, which necessarily relies on interoperability. Instead of being locked in to rigid, all-or-nothing tools, software add-on marketplaces allow utilities to mix and match solutions and build a customized software stack that works for their entire team — not just a few specialists.
By encouraging developers to create and share tools that communicate and share data well with other marketplace tools and external systems, add-on marketplaces can help create a dynamic, flexible ecosystem that empowers utilities to customize their software stack to their operational goals and scale at their own pace.
4. Accelerates technology adoption & digital transformation
Utilities can be reluctant to embrace new technology because of uncertainty, resource constraints, or concerns about the time and effort required to integrate new solutions. Software add-on marketplaces can help to address these barriers by offering ready-to-use integrations and add-ons that are pre-vetted for performance and security, so utilities can transition to new technologies more confidently and efficiently.
With plugins and add-ons they can easily access and trust, add-on marketplaces can simplify utilities’ decision-making and help them fast-track their transition to smart operations. It can also help lower the barriers to experimentation, enabling utilities to test new technologies with minimal risk and investment. This accelerated adoption not only helps utilities address their immediate challenges but also positions them to keep pace with ongoing digital transformation trends.
5. Incentivizes innovation & collective value
Software add-on marketplaces can help make it easier and more rewarding for developers to solve real-world challenges. By providing a platform where teams can build, share, and monetize new tools, marketplaces encourage innovation that’s practical, targeted, and driven by the needs of the water sector itself.
Whether it’s creating a better way to manage assets, plan for climate resilience, or streamline day-to-day operations, developers have the opportunity to turn ideas into solutions that others can adopt and build on.
What’s powerful about the marketplace is that innovation doesn’t stay locked in one place. Every new tool added to the marketplace can spark more ideas and be used, improved, or adapted by others, creating a ripple effect of progress across the sector. Instead of isolated one-off solutions, marketplaces can help build a living ecosystem where best practices spread faster, and the benefits of new ideas are shared widely.
This can open the door for developers who may not be water-sector experts, but have valuable experience from other industries, to create water-sector solutions — introducing fresh thinking and cross-vertical ideas and innovations the sector may not achieve on its own.
By aligning individual success with collective value, software add-on marketplaces can give utilities and developers a shared stake in moving the entire sector forward — creating a future that’s not just smarter, but more connected, resilient, and ready for what’s next.
6. Reduced barriers to entry
Building and delivering new software tools has traditionally required heavy upfront investments — not just in development, but in infrastructure, marketing, and distribution. In practice, that meant innovation was often limited to large companies with deep resources,
while smaller teams with good ideas faced steep hurdles to get solutions into the hands of users.
Add-on marketplaces help change that equation. By offering shared infrastructure — a core platform, APIs, SDKs, access to users, and trusted distribution channels — marketplaces can help give independent developers, small firms, and even utilities themselves a
clearer, faster path to create and share new solutions.
Instead of starting from scratch, developers can build on top of trusted platforms, bringing new ideas to market without needing major investment or access to traditional sales pipelines — it’s a way of shortening the path from idea to impact. Utilities benefit too, gaining access to a wider pool of practical tools — many built by people who know their challenges firsthand.
The result is a more open, inclusive environment where good ideas aren’t gated by company size or budget. When more voices can participate, more real-world problems get solved — and the entire sector moves forward, together.
