As you continue your journey of developing and bringing a new product to the market, you have a series of decisions to make when it comes to prototyping — whether you're going to launch a hardware or a software product, or the combination of both — you need to have a prototype made.

Before you begin, there are a number of things to consider. In an article for InnovationMap last week, I looked at major choice points and their implications that will help you navigate the process in the most efficient way.

After you successfully laid the foundation for the development process and got you CAD models ready, you arrive at the next choice. Prior to making a prototype of your invention you need to decide what type of prototype you're going to build. Whether you're making it yourself or hiring a rapid prototyping company, you need to know the purpose your prototype will fulfil because it will help to select proper methods, techniques, and materials for building. With that in mind, let's go through the types of prototypes and purposes behind building them.

Types of Prototypes

Mockup

This type is usually used as a simple representation of your product idea, to gauge physical dimensions and see its rough look. It's especially useful for making physical models of complex and large products without investing a significant amount from the start. Mockup is perfect for initial market research and various types of early testing.

Proof of concept

This type of prototype is built when you need to validate your idea and prove that it can be realized. It comes in handy when approaching potential partners and investors.

Functional prototype

This kind of prototype is also called a "looks- and works-like" model because it has both technical and visual features of the product presented. It is used for testing product's functionality, conducting consumer surveys, and fundraising campaigns.

Pre-production prototype

This is the most complex type that is made at the latest stage of product development. It's used for ergonomics, manufacturability, and material testing, as well as to minimize risks of defects during manufacturing. This is a model that manufacturers use to produce the final product.

Choosing to Partner with Prototyping Company

It's important to note that prototyping is an iterative process. It is a fusion of art and science that helps you to uncover the full potential of your product, which in turn increases its chances for market success. Therefore, you will likely go through several types of prototypes, with each kind usually requiring a few versions to achieve the parameters you set for the model.

And this process also requires help of a company that builds prototypes or of a professional product development team. You can start looking for the one after you made your first mockup or proof of concept. It is recommended because creating more complex prototypes implies the use of sophisticated equipment, sourcing of materials and components that could be too expensive or complicated to do without an established network of suppliers. Plus, skills and experience play a huge role in creating quality prototypes. Taking all three factors – equipment, experience and skills - into account, it's smart to outsource your prototyping needs to a professional company.

This article is a follow up article to my post from last week. I have also previously contributed to guest columns on the following:

Lessons in prototyping: Choosing the right approach to product development

guest column

When embarking on the journey of developing and bringing a new product to the market, you as an inventor have to consider a multitude of aspects that add to the overall market success of your final product. And prototyping is one of the key product development stages that helps you achieve that.

Whether you're going to launch a hardware or a software product, or the combination of both — you need to have a prototype made. First, it allows you to validate your idea and see if it's worth investing time and money into. Second, it creates opportunities for product improvement, detection and elimination of design flaws, and cost reduction, especially during manufacturing.

Therefore, you will need to make a set of choices before you actually build a prototype to ensure that it results in a viable, cost-effective, and quality market-ready product. Let's look at major choice points and their implications that will help you navigate the process in the most efficient way.

To begin, let's look at the various options you have.

The success of any process lies in its foundation. Hence, before anything else you need to decide on the product development approach you're going to follow. Some inexperienced inventors, for instance, choose to go from product idea straight to having a prototype made. They skip three initial steps that are crucial for building a sound road map of the development process and creating a product with a maximum market potential.

In most cases, those inventors end up coming to companies that build prototypes to start from scratch. Usually, it's because they hit a dead end with their prototype or a product was manufactured with many defects. The latter is always a result of improperly optimized pre-production prototype, if optimized at all.

The extensive experience of our product development team shows that a methodological approach to the entire process, prototyping in particular, yields the most effective results. That's why we always recommend it to those inventors who choose to DIY their prototype. If you're one of them, here is a short version of the approach with steps it implies that you can use prior to prototyping. You can find the in-depth version here.

1. Product discovery

To set the path for the development of your idea you need to identify your product's strengths, weaknesses, opportunities, and threats. In other words, you need to conduct a SWOT analysis, which will help you learn about:

  • intellectual property opportunities
  • your competition and target market
  • features your product should have
  • time and cost of your idea development.

2. Concept design

Based on the results of the SWOT analysis, you can establish the road map of the development of your product and get to creating a concept or industrial design. Concept design is a virtual representation of your idea translated into 2D renderings and 3D CAD models that show you a rough look and functions your product will have. These should be built in accordance with preferences of your target audience to ensure the product's market fit. Concept design is usually made by a professional Industrial Designer. But if you have a basic knowledge of how to use industrial design software applications, then you can make it yourself.

3. Market and prior art research 

Another important step before prototyping is gathering and analyzing feedback from potential consumers. This is done through market research. With a concept design developed, you can conduct focus groups and consumer surveys to understand if the audience likes your idea. The information you get will give you more opportunities to improve your idea and add necessary changes to the design before prototyping, thus reducing the cost of the process and increasing market potential.

Prior Art Search, or research of existing patents, provides some of the benefits as market research. But its main purpose is to identify similar product ideas that have already been patented, so that you can make your product stand out by adding unique features to the design, as well as avoid a conflict of patent rights.

In a follow up article next week, we will discuss more decisions you must make during the prototype process. I have also previously contributed to guest columns on the following:

These are the risks and rewards of prototyping, according to Houston expert

Guest column

We live in a digital world. Music, movies, and even family photos have become primarily digital. Computer software offers us a range of comfort and efficiency and has become part of our daily routine. So, why would anyone want to build a career around physical product development?

Simple, almost every software product or next big thing relies on a well-executed physical product development project. Apps need a place to run, games need a console to be played, and pictures need a camera to be taken.

Physical product development means dreaming of something that does not yet exist and solves an existing problem. It means taking an intangible idea and making it into a physical item that people can see, touch, and use.

The journey from ideation to creation, and then manufacturing can be difficult, but rewarding. By understanding the process, you'll find that not only is your inspiration worth pursuing, but it may be one of the most fulfilling things you will ever do.

From inspiration to perspiration

Every product development project begins with a vision, the identification of a problem and a solution for that problem. That initial spark of inspiration is what drives the entire project.

Look for a problem that hasn't been solved and solve that problem, or try the reverse. Think of a product idea, and then work backwards to find the need. Regardless, one cannot be successful without the other.

Projects require this problem, or need, because it embodies the product's target market. A product idea without a well-defined need has no reason to exist, and if it did, it would be downright perplexing.

Once you identify your need and idea, start your research.

Test the validity of your idea. How much of a market exists for your problem-solving miracle? Send out surveys, look at various markets, conduct data analyses, and generally, do everything in your power to ensure that your product should be made.

Then, start making something.

From concept to reality

The design, prototype and manufacturing stages are what bring your inspiration closer to reality. Turning it into a concrete product means letting go, and that can be scary.

Initial concept designs can be done in a variety of different ways. Detailed sketches and blueprints could be drawn up, or CAD drawings can be created. This concept design can help you explain your idea to others, including partners and investors. What works even better, though, are prototypes.

A prototype is a preliminary model of your product that can help you determine the feasibility of different aspects of your design. You can make a functional prototype, which acts as a proof-of-concept for your idea, or you may create aesthetic prototypes that will test the look and feel of your product.

Once you nail down the ideal appearance and physicality of your product, you will need to combine the two disciplines as seamlessly as possible. This performance prototype will effectively demo your final product.

Finally, you can prepare your product for production. Designing for manufacturability (DFM) means ensuring that your product can be made efficiently and cost-effectively. DFM allows you to mistake-proof your product by choosing the best manufacturing materials and methods, while keeping in mind the appropriate regulations for your desired market.

From nothing into something

The product development process often changes. Trends like crowdsourcing and innovative fast-to-market solutions constantly upend the process and make it new again. Some automakers, for example, want to innovate the design process using existing customer data — similar to how companies like Microsoft and Apple create iterative versions of their software product development projects.

Getting your product to market can be tough, but certain approaches can ease the burden. Create a simpler product. Fail fast and fail cheap with lean development, meaning limit your risk to maximize your return. Also, never underestimate the importance of customer feedback and intellectual property protection throughout the process.

With that said, invest in yourself and your inspiration, and you will avoid that nagging what if-mentality that drives regret. Great reward always requires risk, but there are also ways to invest smarter. Use available resources and give your dream the best chance for success.

Making a product that is worth further investing in, one that customers will want to buy, requires several prototypes, sometimes tens of prototypes to prove the concept and perfect your idea. Photo courtesy of OKGlobal

Houston expert shares why prototyping is so important to startups

guest column

Rarely in life is anything perfect on the first attempt. Writers write drafts that are proofed and edited. Musicians practice over and over, and athletes train for years to perfect their skills before becoming pros. So, it only makes sense that a product developer would develop a prototype before manufacturing their products.

But why? Why can't a perfectly designed product go straight from CAD to production? In reality, making a product that is worth further investing in, one that customers will want to buy, requires several prototypes, sometimes tens of prototypes to prove the concept and perfect your idea. Success comes through practice, just like with the musicians and the athletes.

Defining "prototype"

The word prototype derives from the Greek word meaning, "primitive form." It's an early sample or model of a product built to test a concept or process. Understanding that a prototype, by definition, is an early form of your final product, know that there is often a compromise between your prototype and the final product design. Differences in materials, manufacturing processes and design may create a slightly different look and feel of your prototype.

A full design build is expensive, and it can be time-consuming, so before manufacturing, we create a prototype. This allows you to look for any flaws and problems, figure out solutions, then rebuild with the updates. The process may repeat multiple times. Rapid prototyping is often used for your initial prototype, allowing you to inexpensively build and test the parts of the design that are most likely to be flawed, solving issues on the front end, before you make the full product.

This necessary step is needed to progress with your product development and take you further toward the commercialization and marketing of your product.

Why prototype?

Prototyping allows you to learn about the product, the design, and the functionality. By doing repetitive prototyping, you eliminate the guesswork and base your decisions on actual data and facts. Don't ever guess. Just learn. Just prototype.

Market Testing
It allows you to put a product in front of your consumers, get their opinion, and make changes based on how the consumer uses the prototype.

Save Money
You get to save money on initial product testing, by letting consumers test the product the way they would use it in real life.

Make Improvements
Prototyping gives you the opportunity to make improvements before putting your product into the market. You can see where/if your idea is flawed and flush it out before you manufacture products that won't sell.

Sales Forecasting
This is a difficult enough task as it is, but when you have a new product, it's hard to predict how it will fare against other products in the market. By watching how consumers use the prototype, and by seeing it work against other products, you will begin to understand the sales cycle for that product, allowing you to start your forecasting.

Product designers cannot predict how a consumer will react to a new product, so they release several prototypes, and gather feedback, switching up the products until they find what works for the consumer. When the product went to manufacturing, and finally to market, it was almost guaranteed to be a success—an unintended use for prototyping, and yet one of its best uses.

Designers realize that what looks good on paper isn't always what the end-user is going to want. By getting an inexpensive prototype in front of consumers, designers have been able to get quick feedback, adjust the product, and create a winning product.

When it doubt, prototype it out

The beauty of prototyping is that each prototype interaction opens new opportunities to improve your product. In all reality, you will need more than one prototype to develop a truly valuable product. Product development can get bogged down in meetings, where the product is analyzed, and guesses are made as to "the best way," but by getting to the rapid prototype stage, you can skip some of that guesswork and replace it with real information from the customers.

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

  • Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
  • Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

  • “This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
  • “Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
