Web Design Review from Robert H. Hughes, CERP
Absolute Web designed a new site from scratch to replace our 20-year-old site. It was long overdue, and the process was made easy and manageable by Absolute. I spent months trying to find the right company to work with and found Absolute and Andres. He has been amazing and patient. After 5,000 products and new product images, his team got us to a polished and easy-to-use site. Their pricing was very reasonable and a great value. I would highly recommend Andres and Absolute Web.

eCommerce Development Review from Kelly Johnson
Since partnering with Bilberry, we have seen a marked improvement in our websites stability and performance. Their team manages our backlogged issues with such efficiency that our monthly development spend has actually decreased. Estimates are consistently accurate, and we appreciate their proactive communication; if a projects scope evolves, they provide an updated estimate for approval before moving forward. Our monthly sprints are now seamless thanks to their reliable planning and ability to scale resources rapidly to meet even the tightest deadlines.

Web Development Review from Adam Ely, PMP
As Director of Operations at Sands Investment Group, I partnered with Bilberrry to lead the redesign and rebuild of our website, enhance our marketing operations, and streamline internal workflows. We chose Bilberrry for their strong technical capabilities, cultural alignment, and outstanding reputation.
The project followed a well-structured four-phase process: discovery, design, development, and launch. From the beginning, Bilberrry took a strategic and collaborative approach, conducting workshops and technical audits to define a scalable architecture and intuitive user experience. Their team went on to create custom designs for more than 20 pages, build a flexible design system, and ensure the site met key standards for SEO and accessibility.
On the development side, they customized a robust content management system tailored to our needs, incorporating dynamic listing features such as saved searches, email alerts, and early-access content for select users. The new site also connected seamlessly with our internal tools, enabling greater efficiency and automation across teams.
The impact was immediate and significant: we saw a dramatic reduction in manual processes. Our team is now better equipped to manage content independently, while the platform itself is built for long-term scalability and performance.
Throughout the process, Bilberrry was responsive, professional, and incredibly easy to work with. They communicated clearly, incorporated feedback quickly, and consistently brought thoughtful, strategic ideas to the table. Bilberrry's unique blend of strategic insight, technical depth, and design acumen made them an invaluable partner in creating a high-performing, visually polished digital platform tailored to our business.

Chop Dawg helped us turn our gifting app concept into a working prototype, handling wireframes, UI design, coding, data storage, and automation from scratch. Their team has been transparent, proactive, and highly responsive throughout the process. They provide clear schedules, flag issues early, and keep us informed at every stage.

Chop Dawg took our iOS app from concept to launch, handling design, development, AWS, and App Store requirements. Their team was responsive, practical, and highly supportive throughout the process. They also stayed involved after launch with updates and fixes, and even helped promote the app through their network. Their support contributed to strong early growth and helped position the company for a later acquisition.

Chop Dawg supported us with UX/UI design for a new fintech web application. They took the time to understand our users, product requirements, features, and overall vision before moving into design. Over a 6 to 7 week engagement, their team shared regular Figma reviews, incorporated feedback quickly, and stayed highly responsive. They finished ahead of schedule with no budget issues, and the internal response to the final designs has been very positive. Their attention to detail, professionalism, and ability to keep the process organized made them very easy to work with.

6 Frequently Asked Questions About Software Development Companies in California
What services does a software development company in California typically provide?
It offers the following custom software development services:
Custom software development: Designing, building, and deploying software tailored to specific user needs or business requirements.
Mobile app development: Building Android and iOS applications that leverage native device features such as Bluetooth, camera, and GPS for enhanced functionality.
Web app development: Building software that lives on a remote server and is accessed through a web browser rather than being downloaded onto a device's hard drive.
Website development: Designing and developing both the front-end and back-end of a website, with a focus on responsive layouts, intuitive interfaces, and practical features.
Cloud development: Software developers in California craft bespoke programs that run on cloud environments and allow for secure and easy data retrieval and storage, while offering cloud consulting services too.
Quality assurance: Conducting rigorous tests to identify and resolve potential issues and ensure the software solutions meet performance standards, user expectations, and regulatory requirements.
Maintenance and support: Performing software updates to enhance security, functionality, and performance.
How much do these companies charge for software development services?
Software development pricing in California is among the highest in the United States, driven by talent demand in hubs like Silicon Valley, San Jose, and San Francisco. California sits at the top end globally, often 30-70%more expensive than offshore alternatives.
Costs vary widely by experience level, project scope, and specialization.
In top-tier markets, software developers in California charge $160-$275/hr.
Costs by project
Small projects (MVPs, simple apps): $40,000-$80,000
Mid-size platforms: $80,000-$150,000
Complex systems (enterprise, AI, SaaS): $150,000-$300,000+
What is the Privacy by Design requirement in California?
Privacy by Design (PbD) in California is a core regulatory expectation embedded in the California Privacy Rights Act (CPRA) and the California Consumer Privacy Act framework.
Privacy by Design requires software development companies in California to build privacy into systems from the start, not add it later, integrate privacy into software architecture, business processes, and data flows, and consider user privacy at every stage of development and data processing.
This requirement applies to web and mobile applications, data pipelines and analytics systems, and AI and automated decision-making tools.
How long does it take to complete a software development project in California?
The average timeline for a custom software development company in California ranges from 3 to 12 months, depending on the complexity and scope of the project. While AI-augmented development tools have increased coding velocity by nearly 40%, stricter California regulations (like the CCPA and new AI transparency laws) have added mandatory compliance and testing phases that offset those gains.

Yes, you can. Many top software developers in California use offshore or hybrid teams. In this setup, the agency usually keeps its strategy, design, and project management in California, while teams in Eastern Europe, Latin America, or Southeast Asia handle heavy-duty coding.
While the model is effective, California’s strict laws mean that a software development company in California must be the shield for your business. Even if developers are offshore, they may have access to your users' personal data. Under the 2026 CCPA rules, you must ensure the agency has Data Transfer Agreements in place. The data must be handled as if it never left California.
What is the ADMT regulation?
ADMT stands for Automated Decision-Making Technology. In the context of California law (specifically the CCPA/CPRA), it refers to any technology that uses computation to replace or substantially replace human involvement in making decisions about people.
As of January 1, 2026, new regulations from the California Privacy Protection Agency (CPPA) have officially taken effect, placing strict guardrails on how businesses use these tools. If the software solution you need uses AI to make decisions, a top software development company in California must provide a way for users to opt out and receive an explanation of the logic.
The regulation targets any system, including artificial intelligence, machine learning, and simple algorithms that process personal data to make a significant decision concerning a consumer.
This includes decisions related to:
Employment: Hiring, compensation, or work allocation.
Financial Services: Lending, insurance, or credit.
Essential Services: Housing, healthcare, or education enrollment.
