mbuzz is multi-touch attribution for technical marketers who've stopped trusting their dashboard. Here's the thing nobody selling you attribution wants to say out loud: every tool runs a model under the hood, and the number it reports isn't "the data." It's that model's opinion of the data. Same touchpoints, different model, completely different "best channel."

mbuzz runs eight of them at once. First-touch, last-touch, linear, time-decay, position-based, Markov, Shapley, data-driven. You can compare them, argue with them, and write your own in a SQL-like DSL if none of the stock eight fit how your business actually works.

Possible disadvantages of Fast.com

  • Limited Metrics
    Fast.com primarily focuses on download speed and does not provide as comprehensive a range of metrics as some other speed test websites, such as upload speed, latency, and jitter.
  • No Server Selection
    Users cannot choose which server to run the speed test against, which can sometimes result in less accurate measurements for specific network conditions.
  • No Historical Data
    Fast.com does not offer features to save or track historical speed test results, limiting users' ability to monitor their internet performance over time.
  • Lack of Customization
    There are no options to customize the test parameters, such as test duration or concurrency levels, which might be relevant for more advanced users.
  • Geared for Streaming
    Since Fast.com is tailored for Netflix streaming, it may not fully represent other usage scenarios, such as gaming or file downloads, which require different network performances.

Analysis of mbuzz.co

Overall verdict

  • I don't have verified, up-to-date information about mbuzz.co specifically, so I can't confirm its quality, legitimacy, or reputation. Before using it, I'd recommend checking independent reviews, verifying business registration details, looking for user testimonials on third-party sites, and checking domain age and trust signals via tools like WHOIS or Trustpilot.

Why this product is good

  • No verified data available on this specific domain's services, pricing, or customer satisfaction
  • Unable to confirm business legitimacy, ownership, or operational history
  • Cannot assess user reviews, complaint patterns, or refund/support track record without current data
  • Website content and offerings may have changed since any prior indexing, making assessment unreliable

Recommended for

  • Users willing to do independent due diligence such as checking Trustpilot, Reddit, or BBB reviews
  • Those comfortable verifying site security (HTTPS, privacy policy, contact information) before engaging
  • Anyone considering a purchase or signup who should start with small transactions to test reliability
  • Users who can cross-check company registration and reviews through third-party verification tools

Questions & Answers

As answered by people managing Fast.com and mbuzz.co.

What makes your product unique?

mbuzz.co's answer:

Every attribution tool runs a model under the hood and reports its number like it came from physics. mbuzz is the only one that shows the model. Eight of them side by side, plus a SQL-like DSL to edit or write your own. You stop arguing about which channel works and start arguing about which model you should trust.

Why should a person choose your product over its competitors?

mbuzz.co's answer:

Dreamdata, HockeyStack, and Northbeam all ship with a proprietary "data-driven" model you can't see inside. You pay $1,400โ€“$5,000 a month to trust their math. mbuzz runs eight models you can inspect, lets you edit the logic in a SQL-like DSL, keeps your data exportable on every plan, and starts at $0. For a $1โ€“100M company spending $20Kโ€“$1M a month on ads, that's the difference between renting an attribution tool and owning an attribution stack.

How would you describe the primary audience of your product?

mbuzz.co's answer:

Technical marketers, marketing ops, growth engineers, and data-savvy CMOs at startups and mid-market SaaS, DTC, fintech, and healthtech companies spending $20Kโ€“$1M a month on paid media. Specifically the ones who've stopped trusting their dashboard โ€” who want to audit the math themselves, not hear "trust our algorithm."

What's the story behind your product?

mbuzz.co's answer:

Years of wrestling with the limitations of various existing solutions, platform-inflated ROAS, and enterprise attribution tools that cost more than the budgets they were measuring. Every tool I tried picked one model and hid the math. I wanted to compare models, argue with them, and write my own rules โ€” so I built one. mbuzz is the attribution platform I wished existed when I was trying to explain channel performance to a CFO who didn't believe the Meta pixel.

Which are the primary technologies used for building your product?

mbuzz.co's answer:

Ruby on Rails (backend + dashboard), PostgreSQL, Sidekiq for background jobs, Stimulus/Turbo for the frontend. Open-source SDKs in Ruby, Node, Python, and PHP. Deployed via Kamal on DigitalOcean.
