Possible disadvantages

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing Guide.MD and Nullstack.

Which are the primary technologies used for building your product?

Guide.MD's answer

  • WordPress with a custom PHP directory plugin
  • MySQL for the provider records
  • Cloudflare for delivery and for counting AI assistant and search engine reads
  • schema.org structured data on every profile, so search engines and AI can parse it
  • Weekly NPI registry (NPPES) and CMS data updates

Who are some of the biggest customers of your product?

Guide.MD's answer

  • Independent physicians and dentists
  • Therapists, psychologists and other mental health providers
  • Chiropractors, podiatrists and physical therapists
  • Group practices and clinics
  • Healthcare marketing agencies

Why should a person choose your product over its competitors?

Guide.MD's answer

Most directories run on ads, paid placement or anonymous reviews, and the provider has little say in what they show. Guide.MD starts from official records and lets the provider take over and correct the profile, with no charge to claim it. Claimed profiles list the conditions and procedures a provider actually treats and appear on those pages for their city. Guide.MD also publishes how often AI assistants read it, so providers can see who is reading their profile.

What makes your product unique?

Guide.MD's answer

Guide.MD has a profile for every licensed healthcare provider in the United States, 10.5 million clinicians, practices and hospitals, built from the official NPI registry and CMS data rather than scraped listings. Providers can claim their own profile in about two minutes and correct it. And it is written for AI: profiles are structured, machine-readable pages that AI assistants such as ChatGPT, Claude and Perplexity read about 2 million times a day, so an accurate Guide.MD profile is how a provider shows up when patients ask an AI for a doctor.

How would you describe the primary audience of your product?

Guide.MD's answer

  • Physicians, dentists, therapists, chiropractors, podiatrists, nurse practitioners and other licensed clinicians who want an accurate profile patients and AI assistants can find
  • Practices and hospitals managing several providers from one login
  • Healthcare marketing agencies keeping their clients' profiles accurate
  • Patients, attorneys and companies looking for a provider by condition, procedure, city, or for expert witness and consulting work

What's the story behind your product?

Guide.MD's answer

Guide.MD was founded by Pouyan Golshani, MD, an interventional radiologist in Los Angeles. He saw that the facts about a doctor's work lived on directories that copy each other and go stale, and that patients were starting to ask AI assistants for doctors. AI repeats whatever it can read. So Guide.MD builds every provider's profile from official records and lets the provider correct it, giving patients, search engines and AI assistants one accurate source.
