Wondering if a16z.news is legit? This domain has been around since 2017 and runs a Substack newsletter under the a16z brand, known for venture capital and tech commentary. The site uses standard security protections like encryption and browser safeguards, and it has never appeared on any threat blacklists. For a news or opinion site, the lack of a direct contact button is normal when content is hosted on a platform like Substack. If you're considering subscribing, check that the content matches what you'd expect from a16z—the domain itself is well-established and technically sound. Most visitors will find no scam indicators here, but as always, verify any investment or financial advice independently before acting on it.

How we score →
Where the score comes from
We look at six areas. Here's how a16z.news did in each.
90
Security
Strong security setup: valid certificate, modern TLS, and several browser protections in place. No malware or phishing flags detected.
80
Identity
The domain is 10 years old and registered through a reputable registrar. The registrant is privacy-shielded, which is standard, but the site clearly identifies itself as a Substack publication for a16z, a well-known brand.
85
Reputation
Clean history: no blacklists, an 8-year web archive trail, and mentions on Hacker News. The site has a modest but legitimate web presence consistent with a niche newsletter.
70
Transparency
An About page and legal policies are present, but there's no direct contact email or phone number on the homepage. For a newsletter relying on Substack's platform, that's not unusual, but it does limit direct accountability.
75
Compliance
Privacy policy and terms of service are provided. A dedicated legal entity disclosure is missing, but since the site doesn't process payments or handle sensitive data directly (Substack does), this is a minor gap.
80
Infrastructure
Solid technical foundation: Cloudflare CDN, fast load times, email authentication set up, and a proper sitemap. The large number of external scripts is typical for a hosted platform like Substack.
