AI Development Review from Oleg Sotnikov
Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment. They delivered on time and within budget, communicated proactively, and operated like part of our own team, taking ownership and suggesting better solutions throughout. Deep AI/ML and senior backend expertise. We'd happily work with them again.

Mobile App Development Review from Julia Platova
We partnered with Diffco for a comprehensive software development project aimed at delivering a mobile application and backend system for our client.
The goal was to create a seamless, secure, and scalable solution within a 4-month timeline and $50k-$200k budget.
Diffcos team was highly professional from start to finish. They handled everything: UI/UX design, backend architecture, API integration, and deployment.
After the launch, they continued to support us with maintenance and performance optimization.
The application received positive feedback and has proven stable and scalable.
Were highly satisfied with Diffcos expertise, commitment, and ability to deliver real results.

Mobile App Development Review from Rob Abney
The team at Kinemeric was a pleasure to work with. They took the time to understand our project requirements and designed a plan that accounting for the amount of work the tight turn around and our budget constraints. They pretty much embedded themselves into our engineering team to align all our resources and made sure the project progressed efficiently. They made sure to communicate all roadblocks or deviations from the plan so that our team understood what was happening.

Kinemeric assisted in transitioning our web hosting and management to a new platform and has since been involved in various projects like feature improvements and website revamp. Our site, built on WordPress, was moved to WP Engine's cloud-based hosting service under their guidance. They also integrated GitHub. Other tasks included web design, competitor research, wireframe development, software development, and more.

Kinemeric developed the frontend of our apps and web experience, while my team worked on the backend and APIs.

Alana Muller's Review Sourced from Google
WOW! Working with Crema was a dream come true -- literally! Rarely have I had the opportunity to engage with a partner who so actively listens to its client's vision, considers ways address the request, then magically brings it to life with such finesse... that's exactly what Crema did. With a tight turnaround time and a very public launch, Crema created a beautiful user interface, backend database, and promotional display that activated my product and made it fun and easy to use while perfectly representing my brand. I am so grateful to Crema and will continue to seek opportunities to work with this innovative, creative, and positive group of professionals.

Evan Harmon's Review Sourced from Google
Every experience I've had with Crema has always been a positive one. And every employee I've met there have been incredibly nice, thoughtful, and great to talk to. They have a very cool office space in the Crossroads with great views of KC that just makes you want to hang out there! Crema seems to highly prioritize their company culture by putting on events and having a heathy work/life balance. In short, they seem to really care about people and that carries into their work, judging by how I was able to see their process for developing solutions for their clients at a workshop they held. Using the design sprint methodology, and healthy doses of design thinking, humanistic perspectives, diversity, and pragmatism, they clearly have spent a great deal of effort honing a highly efficient development strategy that makes finding creative solutions a reliable science. It gave me a lot of ideas to bring back to my own projects and meetings! I definitely recommend their design sprint workshop and can only imagine they would be a great company to have tackling your company's challenges.

The Crema office is very cool. Lots of modern touches with a great view of the Kauffman Center for Performing Arts. I recently attended a Design Sprint workshop and had a great time! It was a unique experience and a great tool for solving even the most complex problems. I'm hoping to utilize it in my current role. Justin was a great facilitator and I would recommend using Crema for any Design Sprint needs or even attending the workshop yourself. It was also a great networking opportunity. Highly recommended!

What services do product design companies in the USA provide?
Product design companies in the USA provide a spectrum of services aimed at creating new digital or physical products that solve particular user problems. Their expertise is often sought after for assessing whether a proposed solution is feasible from both a technical and a business perspective.
As part of their portfolio, product design firms offer product/user research services, user experience (UX) design, user interface (UI) design, industrial design, prototyping, usability testing, manufacturing, and launch support.
In terms of demand, the research, strategy, and conceptgeneration segment remains dominant, accounting for over39% of the revenue share. As for applications on the rise, the consumablesand accessories segment is projected to witness a CAGR of 11.06% over the forecast period until 2030.
How much does a product design agency charge in the US?
Product design can cost from $5,000 to over $40,000, depending on the project type and how much detail goes into it. When it comes to price per project type, the cost starts around $2,000 for research and can exceed $50,000 for detailed development.
Based on these estimations, here’s what price ranges businesses can anticipate:
Phase
Estimated cost range
R&D
$5,000-$20,000
Conceptual design
$10,000-$30,000
Prototyping
$15,000-$40,000
Product designers typically charge in one of three ways:
By the hour: Charging for each hour spent on the project
A fixed project fee: A single charge for the whole project, regardless of the time spent
A retainer fee: A pre-agreed sum paid regularly to reserve the designer's services over a certain period
What timelines does the service typically follow?
The timeline will depend on the product type and its complexity, and it will vary from product to product. Typically, product design can take from a few weeks to several months and up to 1 year.
The breakdown by phases usually looks like this:
Discovery phase: Between a few days to over 2 weeks
Wireframing: 30-80 days
Iterative design: Depends on the wireframing, it typically takes as 1.5x longer
Responsive design: Depends on the iterative design time, it typically takes as 0.63x longer
What does a typical product design process look like?
A typical product design process follows a structured set of 10 steps to turn an idea into a high-quality, market-ready product.
The process usually looks like this:
Brainstorming: Teams generate and evaluate ideas to solve a specific problem, encouraging creativity before selecting the most viable concept.
Defining the product: The team clarifies the product’s purpose, core problem, and key features, focusing on what matters most and avoiding unnecessary complexity.
User and market research: Designers and analysts study users, competitors, and market trends to ensure the product meets real user needs and has long-term value.
Sketching concepts: Early sketches explore design directions and layouts before committing significant time or resources.
Prototyping: A basic version of the product is created to show structure, functionality, and user interaction, helping catch issues early.
Specifications and requirements: Detailed documentation defines features, technical requirements, timelines, costs, and responsibilities for development.
Pre-production samples/MVP: Initial samples (or MVPs for software) are built to test feasibility, usability, and readiness for production.
Testing and validation: The product is tested with users and stakeholders to identify flaws, gather feedback, and make improvements.
Development and production: The product is fully built using defined specifications, often with agile methods to manage tasks and priorities.
Quality assurance: Final checks ensure the product meets quality standards, works as intended, and aligns with requirements before and after launch.
What kind of results can businesses expect from a product designer?
If a product features a top design, businesses can achieve 32% faster revenue growth and 56% higher total returns. Design-led organizations are also twice as likely to outperform industry benchmarks on innovation and customer satisfaction.
In addition, well-designed products are shown to reduce development and support costs by improving usability and lowering error rates. Studies show that fixing usability issues early can cost up to 10× less than addressing them after launch.
