The verdict in three sentences
In the Bay Area, the clientele of a longevity or concierge medicine clinic often works in tech, reads the studies and quickly spots an unsupported health claim: the site must prove medical rigor before it charms. A San Francisco agency usually charges 25,000 to 80,000 USD for this kind of site (2026 ballpark), versus 2,900, 4,900 or 8,900 USD at Kolonell at a fixed price. The real gap shows over three years, with content, photos, review and maintenance included.
Upfront cost: San Francisco vs the fixed grid
Ranges drawn from typical local agency quotes and public agency rate pages, 2026 ballpark.
| Provider | Build price | Timeline | Usually included |
|---|---|---|---|
| Bay Area freelancer | 8,000 to 20,000 USD | 6 to 12 weeks | Design and build, rarely copywriting |
| Local agency (SoMa, Mission) | 25,000 to 80,000 USD | 10 to 16 weeks | Strategy, design, build, some copy |
| Premium health and wellness studio | 80,000 to 200,000 USD | 16 to 24 weeks | Brand, video, full content |
| Kolonell Starter | 2,900 USD | 3 to 4 weeks | Presentation site, native copywriting |
| Kolonell Growth | 4,900 USD | 3 to 4 weeks | Broader editorial scope |
| Kolonell Premium | 8,900 USD | 4 to 6 weeks | The multilingual tier, languages set in the quote |
Every Kolonell tier includes a project manager reachable in the Pacific time zone, native English or French copywriting and 3 months of support. Member portal, integrated booking and connection to the patient record: on quote. Tier details are on the international offer.
The pages your site must have
| Page | What it must prove | Common mistake |
|---|---|---|
| Home | Who it is for, which membership model, how to start | "Eternal youth" slogan |
| Membership and pricing | What is included, what is not, price range | Hidden prices, vague list of perks |
| Physicians | Degrees, board certification, experience, real publications | Photo only, nothing verifiable |
| Program and testing | Assessments, biomarkers, imaging, follow-up frequency | Promised results or "biological age reversal" |
| Scientific approach | What data recommendations rest on, limits | Studies quoted out of context |
| Privacy | Which data, what use, who has access | Form asking for medical history |
| Contact and first visit | Response time, discovery call | A bare generic email address |
The FTC polices deceptive health claims and the Medical Board of California oversees physician communication. On data, there is no single federal law: the CCPA, as amended by the CPRA, may apply depending on the clinic's size, and HIPAA depending on how you bill. ADA Title III lawsuits targeting websites are frequent in California: aim for WCAG 2.1 or 2.2 AA. Member emails fall under CAN-SPAM. This is not legal advice.
Hidden costs and three-year total cost
The build price is only part of the bill. Here is an average local agency against Kolonell Growth over 36 months.
| Item | Local agency | Kolonell Growth |
|---|---|---|
| Website build | 45,000 USD | 4,900 USD |
| Additional copy and medical review | 6,000 USD (market assumption) | 3,000 USD (market assumption) |
| Team and premises photography | 4,000 USD (market assumption) | 2,500 USD (market assumption) |
| Legal review of claims | 1,500 USD (market assumption) | 1,500 USD (market assumption) |
| Maintenance over 33 months | 600 USD a month, so 19,800 USD (market assumption) | On quote; market assumption 250 USD a month, so 8,250 USD |
| Hosting over 36 months | 1,080 USD (market assumption) | 1,080 USD (market assumption) |
| Three-year total | 77,380 USD | 21,230 USD |
The 3 included months of support explain the 33 months of maintenance in the Kolonell column; the same basis is applied to the agency for a like-for-like comparison.
When a San Francisco agency is the right call
To be fair: if your project includes a member app, telemedicine, a biomarker dashboard or deep integration with your medical record, you are buying a software product, and a local team with developers and a security lead can be justified. The same goes if you want weekly in-person workshops or a major video shoot. For a credible, fast presentation site, the price difference is better spent on quality photography and serious medical review.
Questions to ask every provider: is the price fixed? Who writes the copy and who reviews it? Who owns the domain, hosting and accounts? What accessibility level is targeted and tested? What does maintenance cost after delivery?

Mini case study
Illustrative example: Presidio Longevity Medicine, one physician and one nurse in Pacific Heights, 150 members at 9,000 USD a year. Choice: Kolonell Growth at 4,900 USD, plus photography at 2,500 USD (market assumption) and external medical review at 1,200 USD (market assumption). Total: 4,900 + 2,500 + 1,200 = 8,600 USD.
Spread over 36 months, that is 8,600 / 36 = about 239 USD a month. A single new annual membership at 9,000 USD covers the initial investment, with 400 USD to spare.
FAQ
Why such a price gap with San Francisco agencies?
Local agencies pay some of the highest salaries and rents in the US and often bill 150 to 250 USD an hour. A remote studio with a fixed grid does not carry those costs.
Can the site be in English and Spanish, or Chinese?
Yes, with Premium, the multilingual tier, at 8,900 USD: languages are set in the quote. Reviewed medical translation often adds 1,000 to 2,000 USD per language (market assumption).
Can we display patient reviews?
Carefully: get written consent, avoid any testimonial promising a health outcome and do not cherry-pick only positive reviews. FTC rules on reviews apply to US businesses.
How long until we are live?
Allow 3 to 4 weeks with Kolonell (Premium, 4 to 6) once content is approved, versus 10 to 16 weeks with a local agency. Add 1 to 2 weeks for medical review.
What does maintenance cost afterwards?
After the 3 included months, it is on quote. In the Bay Area market, expect 250 to 800 USD a month (market assumption) depending on update frequency.
Let's scope your project. A rigorous, fast longevity clinic website, on Growth, or on Premium, the multilingual tier, if other languages are needed, live in 3 to 6 weeks after content approval. See the international offer or request a free quote: detailed reply within 48 hours.
