Website design for San Francisco, delivered remotely

We take on website work for San Francisco businesses remotely from Malvern, PA, and every stage is reviewed in your own browser.

Why it matters: 133,246 business establishments operated in the metro in 2023, and 85.5% of them employed fewer than 20 people.

Go deeper: how a remote build runs, stage by stage

Health care and social assistance alone holds 13.2% of the 2,417,363 paid employees counted in the metro in 2023.

Professional, scientific and technical services adds 13.2% and information 12.1%, so three sectors hold 38.5% of the payroll count.

The three cards above are the three largest of the 12 sectors we read for the metro, by paid employees: health care and social assistance, professional, scientific and technical services and information.

Hospitality and food is fourth, with 222,923 paid employees in 13,736 establishments.

  1. Health care

    319,201 paid employees across 16,920 establishments in 2023; a site here needs online booking, intake forms and an accessible path for every patient.

  2. Professional services

    318,400 paid employees across 23,140 establishments in 2023; a site here needs proof of expertise, case pages and a routed enquiry form.

  3. Information

    292,679 paid employees across 4,360 establishments in 2023; a site here needs pages that load fast under heavy content and sign-up flows that work.

Websites we built

Six live sites we built open here in a preview window, the same way your build is reviewed before launch.

Why it matters: A working site shows how a build loads, reads and takes an enquiry, which no mock-up can.

Go deeper: how the previews work

Preview opens the live site inside a sandboxed frame on this page. Atlas Peptides blocks framing, so its preview is a dated screenshot instead.

None of the six is presented as a San Francisco business; each one shows a job a site has to do, whatever the city.

Between them they cover a configurator that prices as you build, online scheduling, booking with reviews pulled in, a shared stock count, a quote form and a checkout.

133,246 businesses, in public numbers

The metro had 133,246 business establishments in 2023, +1.7% since 2018, by County Business Patterns.

By the numbers: 4,648,486 people lived in the metro in 2024, −1.8% since 2019, and payrolls counted 2,417,363 employees.

Go deeper: what County Business Patterns counts

Of the 133,246 establishments, 113,969 had fewer than 20 people and 15,781 employed 20 to 99. Another 2,993 employed 100 to 499, and 503 employed 500 or more.

Within the 20-to-99 band, 11,808 establishments had 20 to 49 people and 3,973 had 50 to 99. The average establishment employed 18.1 of the 2,417,363 paid staff.

County Business Patterns counts employer establishments, locations with paid staff, so a sole owner with no employees is not in the 133,246; that is one establishment for every 34.9 residents.

NAICS 541511, custom computer programming, includes custom web page design and all other custom software, so 222.1 per 10,000 businesses is a ceiling on web-design firms in the metro.

Health care leads, with 319,201 employees

Health care and social assistance employed 319,201 people in the metro in 2023, the most of the 12 sectors we read.

Why it matters: who a site talks to follows the sector mix, and professional, scientific and technical services comes next at 318,400 employees.

  • Health care: 18.9 employees per establishment; booking and intake matter most.
  • Professional services: 13.8 employees per establishment; expertise must be easy to check.
  • Information: 67.1 employees per establishment; speed under heavy content matters.
Go deeper: who these pages are written for

16,920 health care and social assistance establishments in the metro need online booking, intake forms and an accessible path for every patient. The 23,140 in professional, scientific and technical services need proof of expertise, case pages and a routed enquiry form.

Information counts 4,360 establishments that need pages that load fast under heavy content and sign-up flows that work, and accommodation and food services, fourth at 222,923 employees, needs hours, menus and bookings that read on a phone in a hurry.

Retail trade ranks fifth at 198,184 employees, and the 12 sectors we read cover 2,093,076 of the 2,417,363 paid employees in the metro.

Together the four employ 1,153,203 people, 47.7% of the payroll count; the sector figures shape the scope, and the six sites above are our delivered work.

2,959 custom programming firms in the metro

2,959 custom computer programming establishments (NAICS 541511) operated in the metro in 2023, −0.3% since 2018.

Yes, but: that code also covers all custom software, so 222.1 per 10,000 businesses is a ceiling on web-design firms, not a count.

  • Graphic design (NAICS 541430): 416 establishments in 2023.
  • Marketing consulting (NAICS 541613): 1,201 establishments in 2023.
  • Advertising agencies (NAICS 541810): 328 establishments in 2023.
Go deeper: how to compare the firms on your list

With 3,375 programming and graphic design establishments in the metro, ask each firm for live sites you can open, who will own the code and domain, and a written scope.

The wider NAICS 5415 group, computer systems design and related services, counted 5,029 establishments, 377.4 per 10,000 businesses.

Marketing consulting (1,201) and advertising agencies (328) often sell websites too, so the full field in the metro is wider than the programming count.

Custom programming establishments went from 2,967 in 2018 to 2,959 in 2023, while graphic design stood at 416, 31.2 per 10,000 businesses.

Those 2,959 programming firms employed 58,995 people, about 19.9 each. The wider 5415 group employed 85,520.

From 131,036 to 133,246 businesses since 2018

Establishments in the metro rose from 131,036 in 2018 to 133,246 in 2023, a change of +1.7%.

The bottom line: educational services grew the most of the 12 sectors, +12.2% in establishments, while wholesale trade moved −14.1%.

  • 20 to 99 employees: 16,281 establishments in 2018, 15,781 in 2023.
  • 100 to 499 employees: 3,006 in 2018, 2,993 in 2023.
  • 500 or more employees: 387 in 2018, 503 in 2023.
Go deeper: what the change means for a website

Educational services went from 2,670 to 2,996 establishments between 2018 and 2023; wholesale trade went from 5,991 to 5,144.

Health care and social assistance came second, +11.8%, and real estate, rental and leasing third, +9.6%.

That is a net gain of 2,210 establishments: each new one needs a first site, and each established one carries addresses and rankings a rebuild must keep.

Paid employees went from 2,214,178 to 2,417,363 over the same years, +9.2%. Population moved −1.8% from 2019 to 2024, to 4,648,486.

Ranked 25th of 64 places by businesses

The metro ranks 25th of the 64 places we build pages for by business establishments, and 3rd for programming firms per 10,000 businesses.

By the numbers: population growth since 2019 ranks 62nd of 64, and the share of establishments under 20 staff ranks 22nd.

Go deeper: why every place is measured the same way

Every place page uses the same Census tables, so these ranks compare like with like: 133,246 establishments here against the 64 places' own counts, 54th for their change since 2018.

Programming firms run 222.1 per 10,000 businesses here against a median of 85.2. The under-20 share is 85.5% against 84.4%.

The 64 are the places whose web design searches clear 500 a month in Semrush's exact data, state pages counted with any places folded in; this one draws 1,090, 40th of the 134 places we measured nationwide.

How a San Francisco web project runs

A project here runs in the same five stages as every build of ours, from agreeing what the site is for to launch.

What you get: the scope, price and schedule in writing at stage two, before anything is designed or built.

Go deeper: what happens at each stage

Stage one fixes who the site talks to; in the metro, where health care and social assistance employs 319,201 people, that answer often sets the integrations.

Stage five hands the site over in your own accounts, a handover any of the 5,029 systems design establishments in the metro could pick up from.

For the 23,140 professional, scientific and technical services establishments here, stage two usually lists proof of expertise, case pages and a routed enquiry form.

The five stages in order; the written scope, price and schedule come at stage two.
  1. Agree what the site is for

    Who the site talks to, what it must get them to do, and what it connects to.

  2. Scope, price and schedule in writing

    Pages, integrations, price and dates on paper before any design starts.

  3. Design in the browser

    Real content at real widths, reviewed on your own phone as it takes shape.

  4. Build and wire it up

    Code, forms, CRM, analytics and accessibility checks, in one pass.

  5. Launch, hand over, stay on

    The site goes live in your accounts, and we stay on for support.

Working with us from San Francisco

San Francisco runs on Pacific time, so our 9-to-5 Eastern day is 6 a.m. to 2 p.m. there.

The bottom line: the office answers (610) 890-9711 Monday to Friday, 6 a.m. to 2 p.m. local time, the day 2,959 programming firms here keep.

Do you have an office in San Francisco?

No. Our one office is in Malvern, PA, and projects here run remotely, with every stage reviewed in your own browser.

Go deeper: calls, reviews and where the work happens

Calls and screen-shares cover the whole build, and you review the work in your own browser between them; no branch office or answering service sits in between.

Web design questions from the metro

Not answered here? Call the office: (610) 890-9711

Yes. We take on website work for San Francisco businesses remotely from Malvern, PA, and every stage is reviewed in your own browser. You deal directly with the people designing and coding the site, and calls are set in Pacific hours, the clock the metro's 133,246 establishments keep.

The scope sets the price, not the ZIP code: pages, integrations and what the site must do, for one of the 113,969 small establishments here or a larger one. You get the price and schedule in writing first; advertisers paid about $10.39 a click for the main web design phrasing here (Semrush).

Hire a designer when the site has to book, quote, sell or connect to a CRM; a builder fits a site a standard template can serve. In the metro, 85.5% of establishments employ fewer than 20 people, so we say which route fits before quoting anything.

Yes. Titles, headings, page speed and schema go in while the site is built, and Search Console is connected at launch, so the 1,090 monthly searches (top phrasing 720) in the table above are targeted from day one. “web design san francisco” alone draws 720 a month, by Semrush’s count.

Open the live sites a firm has built, ask who owns the code, domain and hosting, and get the scope and price in writing. With 3,375 programming and graphic design establishments in the metro, and 222.1 programming firms per 10,000 businesses, those three checks shorten the list quickly.

The site goes live on hosting in your name, with the domain in your account, and we stay on for support under the written proposal. Any of the 5,029 computer systems design establishments in the metro can pick it up later, because nothing is locked to us.

Yes. We build to WCAG 2.1 AA: keyboard paths, contrast, labels and headings checked before launch, with no overlay and no certificate claimed. It matters most for the 16,920 health care and social assistance establishments in the metro, whose patients include people of every ability.
