Teams we have built software for

Book us to keep your San Jose engineers on the core product while we ship the internal tool, portal or AI feature in about 7 weeks, documented for whoever owns it next.

Our team is based in San Francisco, an hour up the peninsula and on the same clock, with 16 in-house engineers and 30+ remote specialists. Spirit Airlines, Citi and the Miami Dolphins have run software we built, and we publish every build with its results.

Which California laws change how your app is built?

The California rules we design consent screens, data retention and breach logging around. A planning summary, not legal advice.

RuleWhat it means for the build
Consumer privacy lawCalifornia Consumer Privacy Act as amended by CPRA (Cal. Civ. Code § 1798.100 et seq.; regs 11 CCR § 7000 et seq.), in effect from 2020-01-01. Applies to: For-profit doing business in CA that (a) has annual gross revenue > $26,625,000 (CPI-adjusted from $25M), or (b) annually buys, sells or shares personal information of >=100,000 consumers or households, or (c) derives >=50% of annual revenue from selling or sharing personal information. Requires honouring universal opt-out signals such as Global Privacy Control, so the app needs an opt-out flow that reads the browser signal.
Data breach notificationCal. Civ. Code § 1798.82 (amended by SB 446, Stats. 2025 ch. 319): notice deadline 30 calendar days from discovery (from 2026-01-01); sample notice to AG within 15 calendar days of notifying consumers if >500 residents. We build audit logs that show what data was touched, so notice can be accurate and on time.
CPPA regulations: ADMT, risk assessments, cybersecurity auditsRegs effective 2026-01-01: risk assessments from 2026-01-01 (attestation/summary due 2028-04-01); ADMT rules for significant decisions from 2027-01-01; cybersecurity audit certifications due 2028-04-01 (revenue >$100M), 2029-04-01 ($50-100M), 2030-04-01 (<$50M). (effective 2026-01-01)
Delete Act / DROP (Delete Request and Opt-out Platform)Registered data brokers must access DROP at least every 45 days from 2026-08-01 and process consumer deletion requests; independent audits from 2028-01-01. (effective 2026-08-01)

SB 243 companion chatbotsCompanion chatbot operators must disclose AI, run suicide/self-harm protocols and add minor safeguards; annual reporting from 2027-07-01. (effective 2026-01-01)
Sales tax on SaaSnot taxable: Reg. 1502(f)(1)(D): prewritten programs transferred by remote telecommunications not taxable unless storage media transferred; custom programs not taxable (f)(2)(A).. Relevant if you will sell your app as a subscription.
Time zonePacific. Our team works from San Francisco (Pacific), with remote specialists covering other hours, so San Jose working hours overlap with ours every weekday.

What does it cost to hire our custom software development company in San Jose?

$7,000 to around $25,000-$30,000

Our own price for a San Jose build, project-based or hourly, in writing before any work starts. Design, the build, testing, store launch and a handover in your name are included; the pricing page lists what is in and out.

Why San Jose teams hand their backlog to our mobile app development company

In Silicon Valley the engineers exist; their time is the scarce part. The ops dashboard, the partner portal, the approval workflow and the admin screen for the old system all sit at the bottom of the roadmap because the core product always wins. We take those projects off your team's plate. Spirit Airlines' group booking platform, built in 10 weeks with a pricing engine and an approval chain, lets the same six-person desk handle about four times its earlier volume. Edge Case Capital's internal tool took 6 weeks and is used by all nine people at the fund.

We work like an extension of your team: your repo or ours, your code review rules, your cloud, a demo every week. When the build is done you get a recorded walkthrough and written documentation, so a junior owner can run it. Need a customer-facing mobile app or an AI feature on your own data instead? Same team and same price range. If you already have a tool whose authors have left, our maintenance and support or legacy modernization service starts by documenting what is there.

How to hire an app developer in San Jose: 5 things to settle first

  1. Will you work in our repo, cloud and SSO?

    Decide whether we work in your GitHub organization and cloud account or set up new ones in your name. Either way you own them; deciding early saves a week of access requests.

  2. Does a CPPA cybersecurity audit affect the tool?

    Under the CPPA's regulations, covered businesses certify cybersecurity audits by April 1, 2028 (revenue over $100M), 2029 ($50M to $100M) or 2030 (under $50M). New internal tools that hold personal data should log access in a way your auditors can read.

  3. Will the tool hold employee or customer personal data?

    If your business is covered by the CCPA, access, deletion and opt-out requests apply to the data the tool stores. We design admin screens to answer them.

  4. Who maintains it after launch?

    Name the person or team who will maintain it. We write the documentation and record the walkthrough for them, not for us.

  5. Is the price and scope in writing before work starts?

    Screens, integrations, milestones and price, on paper. Our pricing page covers how project and hourly billing compare for internal tools.

Custom software development company in San Jose: questions people ask

How much does custom software cost in San Jose?

Our projects typically cost $7,000 to around $25,000 to $30,000. A single-purpose internal tool is near the low end; several integrations, approval chains and payments push it toward the top. Location does not change our price. You get a written quote after a free 30-minute call, billed by project or by the hour.

How long does it take to build an internal tool?

Half of our 44 published builds reached a first release in 7 weeks or less, and none took more than 10. Edge Case Capital's tool took 6 weeks; Spirit Airlines' booking and admin platform took 10 because it runs on live fare inventory. Access to your systems early is the biggest single factor in hitting the date.

How much does it cost to build an AI app?

Most AI apps we build fall inside our usual $7,000 to around $25,000 to $30,000 range. A single AI feature, such as search or summaries over your own documents, sits lower; an assistant that takes actions across several systems, with permissions and usage tracking, sits higher. We price it in writing after a free 30-minute call, by project or by the hour.

How much does it cost to develop an app for iOS?

An iOS app from us typically costs $7,000 to around $25,000 to $30,000, depending on screens, integrations and features such as payments or AI. Adding Android adds work, and the written quote shows exactly how much. Apple also charges $99 a year for its developer program, which is registered in your name so the App Store listing is yours.

Why outsource software when we have our own engineers?

To keep them on the product. Internal tools, portals and admin systems matter, but they rarely win the roadmap fight. A scoped outside build ships them without pulling your engineers for a quarter, and our documentation and recorded walkthrough mean your team can take it over without a long handover.

Can you work inside our repo and follow our code review?

Yes. We can work in your GitHub organization, cloud account and CI, follow your branching and review rules, and use your SSO. Or we set up new accounts in your name. Either way, the code and infrastructure belong to your company from the first commit.

Which California privacy rules apply to internal tools?

If your company is covered by the CCPA, the personal data a tool holds, including customer and employee records, is subject to access and deletion requests. CPPA regulations also set cybersecurity audit certification deadlines from April 1, 2028, based on revenue, and a breach must be reported to residents within 30 days.

How do I choose a software development company in San Jose?

Ask for builds with named clients and measured outcomes, who exactly writes the code, a written scope with milestones and price, and how documentation and handover work. Confirm the code and accounts will be yours. Your own engineers can then review a sample of the team's work before you sign.

How much does it cost to maintain an app?

That depends on how often you change it, so we do not sell a monthly plan. After launch, support from us is optional and billed per hour, only when you need fixes, updates or new features. You also pay your own hosting and store fees directly, since the accounts are in your name. Our written documentation lets any team maintain it.

Do you need to be on-site in San Jose?

No. Our team is based in San Francisco, on the same hours, and every project runs on video calls, a shared channel and a weekly demo. Most internal tool work needs access to your systems and the people who use them, not desks in your office.
