We brought Goji Labs on board for a major migration project, and the entire experience was smooth and well-managed from start to finish. We could not be happier with the results. Their expertise gave us confidence throughout the process, and we would not hesitate to work with them again.

Designli Reviews & Testimonials
Mobile App Development Review from John Laporte
Designli helped us define the requirements, features, and user experience for an app for our motorcycle organization. They produced technical documentation and a clickable prototype covering navigation, member tools, and safety features. They were responsive, delivered on time every time, and turned our broad concepts into something people could actually click through. The prototype got our stakeholders aligned, earned internal approval, and set us up for engineering, and working out design questions early should save us rework later.
Mobile App Development Review from Brandi Heffner
Designli built our SaaS product from scratch, using AI to speed up development, with AWS and Cloudflare in the stack, and they also handle our hosting and maintenance. We had a working MVP in just 30 days and have kept adding features since. In the first 60 days they went beyond what we expected, largely because they took the time to really learn our business and our market. Coordination through Basecamp and Google Meet has kept everything organized.
Mobile App Development Review from Thomas Simmons
Designli took over app development and marketing for our driving school, with the goal of building a product we could eventually offer to other schools. Within two and a half months, the app was up and running in our own school. Their project management is excellent, and they push back constructively, thinking through what we actually need instead of building every request as-is.

Our company had such a wonderful experience with this team! Their design work is top-notch, and they did a really wonderful job of walking us through the process, but also finding ways to go above and beyond with things we needed additional help with, such as connecting Google Analytics. Highly recommend and would use again.

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.
Web Design Review from Ari Bixhorn
Bilberrry’s work gave our new website improved performance, greater SEO flexibility, and pages that are much easier to build. They delivered everything on time and kept communication proactive throughout. Their strong project management, technical expertise, and responsiveness built real trust during the process.

Communication was excellent throughout, with their team readily available to address any questions or concerns. They not only revamped our website's design but also developed it with precision and creativity.

Mobile App Development Review from Jonathan Fruitman
We thought that their proposed milestones were ambitious. I remember being pleasantly surprised after the first demo. Perhaps based on previous experience, my expectations were too low, but the team really did deliver on a consistent basis.

We couldn't be more pleased with our experience with TouchZen.

How to Hire a Software Development Company in California
What can California software developers do for businesses?
When businesses work with California agencies, they get access to a deeper innovation ecosystem, stronger specialized talent, and more experience building innovative solutions for high-growth markets.
California remains the undisputed global leader in software production and talent density.
The state is funding projects for software-defined submetering, managed EV charging, and vehicle-to-everything (V2X) platforms.
One 2025 grant approved $693,611 to fund managed charging analysis, and another state-backed project is developing a software-defined submetering solution for EV site hosts.
That points to real depth in energy software, grid tech, and mobility platforms.
For a business owner, hiring software development companies in California means tapping into the world's most stable and well-funded innovation hub.
As of early 2026, California's tech sector contributes approximately $541 billion to the state's economy annually.
This represents nearly 19% of California's total GDP, providing a level of infrastructure and talent density found nowhere else.
In 2026, California developers will become the first truly AI-native workforce.
San Francisco-based companies alone received 34% of all total U.S. AI funding in recent cycles, ensuring that agencies in this region have early access to the most advanced tools and talent.
For example, in 2025, Bay Area AI companies pulled in roughly 76% of the U.S. AI funding, according to industry reports.
About 93% of developers in the region now use AI coding assistants.
AI tools have reduced the time it takes for new engineers to get up to speed on complex codebases, ensuring that if your project needs to scale quickly, the software company can add talent without a significant productivity dip.
Gartner predicts that 40% of enterprise applications will be integrated with task-specific AI agents by the end of 2026.
Software developers in California build autonomous agents that don't just chat but also execute workflows, such as reconciling accounting books, managing supply chain logistics, or providing first-tier customer support without human intervention.
Early adopters of agentic workflows in California report a 25% reduction in operational overhead within the first year of deployment.
Because of the CCPA and SB 942 (AI Transparency), California agencies build innovative solutions with a Privacy by Design philosophy.
This prevents the compliance tax, i.e., the massive cost of re-coding an app later to meet mandatory state privacy standards.
For every $1 spent on high-end California software development, mid-market California businesses report an average 3.5x return on investment (ROI) within 24 months through operational automation and new revenue streams, according to recent industry analysis.
Why should I hire a California-based agency vs. an out-of-state one?
While out-of-state or offshore agencies offer lower rates, a custom software development company in California can be a stronger choice for your business needs if you want a partner with proven expertise that is closer to the state's talent, capital, and regulatory environment.
California's life sciences sector alone included about 16,000 businesses, 70,000 biotech R&D employees, and $60 billion in private investment in 2023.
If your business operates in healthcare, medtech, biotech, or regulated industries, California firms are more likely to understand those workflows and compliance needs.
In 2025, California partnered with Google, Adobe, IBM, and Microsoft to expand access to AI training for over 2 million students across public schools, community colleges, and California State Universities.
For buyers, that means local agencies are hiring from a workforce pipeline being trained around modern AI tools and workflows.
California has the strictest data and AI laws in the U.S.
Hiring locally means your custom software solutions are built to the highest legal standard from day one.
The state employs over 628,400 software developers, which is more than twice as many as Texas, the next closest state.
In 2026, the state announced a $2.75 million CCPA settlement with Disney, the largest CCPA settlement in California history at the time.
If your product handles consumer data, a software developer in CA is more likely to build software having these rules in mind from day one.
California is home to 33 of the world's 50 leading AI companies.
If your project touches AI development, automation, or data-heavy products, software development companies in California are more likely to work in that ecosystem every day.
In 2024, 15.7% of all U.S. AI job postings were in California, versus 8.8% in Texas and 5.8% in New York.
That makes California the deepest single-state market for AI hiring.
According to CalPrivacy, California's privacy regulator reported a $15.8 million budget in 2025, up from $12.8 million in 2024, and 54 positions in 2025, up from 40 in 2024.
That signals a growing compliance and enforcement environment, which is useful if you want a software engineering partner that takes privacy seriously.
California handles more than $675 billion in two-way trade and is the largest importer among the U.S. states.
Agencies in that environment are more likely to have experience with multilingual, cross-border, compliance-sensitive, and high-volume digital systems.
How do I choose the best software development firm in California?
Follow these steps to ensure you choose the best software development company in California for your business needs:
- Start with product fit
Choose a firm that has already built the kind of product you need: SaaS, internal tools, AI features, healthcare software, fintech, or eCommerce. Ask for 2-3 recent examples that match your exact use case, tech stack, and compliance needs. - Make privacy and compliance a selection filter
A strong software development firm in CA should be able to explain opt-outs of rules and regulations, consent flows, data minimization, and privacy-by-design in plain English before it writes a line of code. - Check whether the firm can scale with you
The best partner should support growth, maintenance, and hiring transitions. Ask how the agency staffs phases 1, 2, and 3 of growth. - Ask who owns the communication and delivery
Some custom software development companies in California sell senior strategy but push execution elsewhere. Require a named product lead, tech lead, and delivery owner in California or your time zone, plus a written cadence for demos, issue tracking, and risk reporting to ensure timely delivery and top technical expertise. - Use a scorecard before you sign
The safest way to choose is to score each firm on relevant case studies, technical depth, privacy/compliance readiness, team seniority, communication model, maintenance support, and commercial fit. A simple weighted scorecard will help you separate polished sales from real delivery capability.

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.
| Project type | Timeline | Key focus area |
| Minimum Viable Product (MVP) | 3-4 months | Core features only; rapid market entry. |
| Medium complexity SaaS | 6-9 months | API integrations, multi-user roles, and scaling |
| Enterprise-grade systems | 9-18+ months | Legacy migration, high security, and deep compliance. |
| AI-native platforms | 12-24 months | Model training, ADMT audits, and data lineage. |
Can I hire a California agency that uses offshore developers?
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.Â
This includes decisions related to:
- Employment: Hiring, compensation, or work allocation.
- Financial Services: Lending, insurance, or credit.
- Essential Services: Housing, healthcare, or education enrollment.
- Criminal Justice: Legal outcomes or profiling.
