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.
| Rule | What it means for the build |
|---|---|
| Consumer privacy law | California 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 notification | Cal. 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 audits | Regs 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) |
| AB 1043 Digital Age Assurance Act | OS providers collect age/birth date at device setup and send an age-bracket signal to apps; developers must request and use the signal. (effective 2027-01-01) |
| SB 243 companion chatbots | Companion 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 SaaS | not 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 zone | Pacific. Our team works from San Francisco (Pacific), with remote specialists covering other hours, so San Francisco working hours overlap with ours every weekday. |

Apps and software we build for San Francisco businesses
| Industry | The problem | What we build |
|---|---|---|
| AI startups and B2B SaaS | Each AI assistant or workflow you sell is a custom project, so onboarding a customer takes weeks. | A multi-tenant AI platform where each assistant is a configuration on a shared knowledge base, with usage tracking and billing per account. AI app development |
| Consumer apps | You have a strong idea and a waitlist, but no product people can use yet. | A focused consumer app that does the one thing users signed up for, with analytics from day one so the next round of decisions is based on data. MVP development |
| Marketplace founders | Supply lives in a spreadsheet and every match still depends on you making a phone call. | A two-sided marketplace with listings, search, booking and payouts, so supply grows without you calling anyone. Marketplace app development |
| Funds and fintech operators | Deals, memos and approvals are spread across inboxes and partners, and nothing gives one view. | A custom pipeline and memo tool with scoring and an approval trail, the system that cut Edge Case Capital's memo prep from six hours to 90 minutes. Custom CRM development |

Why San Francisco founders hire our mobile app developers
Most San Francisco briefs we hear are one of three: an AI app on top of a company's own data, a SaaS product that needs accounts and billing, or a two-sided marketplace that has to prove supply and demand fast. We have shipped all three. Think K-12's Ingio runs many AI assistants from one knowledge base; we built it in 7 weeks and it signed 3,400 business accounts in year one. Birdie turns saved social posts into trip itineraries and produced 88,000 itineraries in its first year after an 8-week build. GoHangars' MVP shipped 7 weeks after the first call and the founder closed a seed round nine months after launch.
Working with a team in your own city keeps everything on one clock: same-day answers, weekly demos you can join between meetings and decisions made the day they come up. Need a native iOS and Android app rather than a web product? Same team, same price, and a test build on your phone every week. You can meet the people behind the work on our about page, read how engineering runs on Shivam Pujara's profile, or get a first number from the app cost estimator. If you also need a CRM wired up alongside the product, we run CRM setup in San Francisco too.

How to hire an app developer in San Francisco: 5 things to settle first
- Will your AI make significant decisions about people?
Under the CPPA's regulations, businesses using automated decisionmaking technology for significant decisions must comply from January 1, 2027. If your product scores, ranks or approves people, plan notices, opt-outs and records into version one.
- Is it a companion or chat product?
California's SB 243 has applied to companion chatbots since January 1, 2026: disclose that the user is talking to AI, run self-harm protocols and add safeguards for minors. Settle whether your product falls under it before you design the chat.
- What must version one prove?
Pick the one metric your next raise or customer depends on, and cut everything that does not move it. That is what keeps an MVP near our 7-week median.
- Who owns the repo, cloud and model accounts?
You do. API keys, cloud projects and app store listings are created in your name, and handover includes a recorded walkthrough and written documentation.
- Is the price and scope in writing before work starts?
Screens, integrations, milestones and price, on paper. The pricing page breaks down why an AI feature or a marketplace costs more than a single-flow MVP.

How much does it cost to build an MVP in San Francisco?
Our MVPs and apps usually cost $7,000 to around $25,000 to $30,000. One core flow with sign-up sits near the low end; AI features, payments, two-sided marketplace logic and integrations move it up. You can pay by project or by the hour, and the number comes in writing after a free 30-minute call.
How quickly can a startup ship its first version?
Across the 44 builds we publish, a first release took between 5 and 10 weeks, and the median was 7. Ingio and GoHangars each shipped in 7 weeks; Birdie took 8. We agree the scope in writing first and show working software every week, so you can cut or add features before they cost you time.
Can you build an AI app on our own data?
Yes. We build assistants, search and summarization features, and AI workflows on top of your documents, product data or CRM, with permissions so each user sees only what they should. Think K-12's Ingio, which we built in 7 weeks, cut assistant deployment from six to eight weeks to 20 minutes.
Can you add AI to my existing app?
Yes, in most cases we add AI to the app you already have rather than rebuilding it. We review your code and data first, then add features such as an assistant, smart search or summaries behind your existing logins and permissions. The free 30-minute call tells you whether your current code can take it, and the price comes in writing before work starts.
How much does it cost to build an app for iOS and Android?
Most of our apps cost $7,000 to around $25,000 to $30,000, and that range covers apps that ship to both the App Store and Google Play. Supporting two platforms adds work compared with one, and your written quote shows exactly how much. Store fees are separate and small: Apple charges $99 a year for its developer program, and Google Play charges a one-time $25 registration fee.
Do California AI rules affect our product?
They can. CPPA regulations require businesses using automated decisionmaking for significant decisions to comply from January 1, 2027, and risk assessments began January 1, 2026. Companion chatbots must follow SB 243. If you meet a CCPA threshold, privacy requests and opt-outs apply as well. This is planning guidance; your counsel confirms what applies.
Is aibrevo actually based in San Francisco?
Yes. aibrevo was founded in 2021 and our team is based in San Francisco. Alpit Patel is founder and CEO, and Shivam Pujara is co-founder, COO and CTO and leads our 16 in-house engineers. Thirty-plus specialists work with us remotely. San Francisco clients share our hours exactly.
Do I need an NDA before talking to an app developer?
You do not need one for a first call, but you can ask for one and we sign it on request. Most founders share the problem and the users on the free 30-minute call, then the details once an NDA is in place. More important than the NDA: the code, repository and accounts are in your name from the first commit, so the product is yours.
How do I choose an app development company in San Francisco?
Judge on shipped products with named clients and real numbers, not on pitch decks. Ask who writes the code, get the scope, milestones and price in writing, and confirm the repository, cloud and app store accounts will be yours. A good partner will also tell you which features to drop from version one.
Should we hire engineers or use an outside team first?
If software is your product, you will want your own engineers eventually. Many founders use an outside team to ship the first release while they hire, then hand the product to their team with our recorded walkthrough and documentation. Support after launch is optional and billed per hour, so you can keep us only as long as it helps.
