If you're deciding between these, you deserve a straight answer instead of a marketing dance. So here's the honest comparison, including the parts where they beat us.
Definitive Healthcare and AcuityMD are enterprise data platforms built for the company: bigger datasets, commercial-payer claims, annual contracts sold through a sales team. Prospect 811 is built for the individual rep: Medicare billing data in your own hands, self-serve, $79 a month on a personal card, cancel anytime. If your company has the budget and a data team, buy them. If you're the one actually knocking doors, this is the one you can buy today without asking anyone.
I spent six years in medical device sales, so I'll tell you how this actually works at most companies. The company buys an expensive data platform. An analyst or a sales ops person gets the login. Once a quarter, something filters down to you: a spreadsheet, a target list, a slide. By the time it reaches your truck it's someone else's idea of your territory.
And that's the good case. Most companies, including plenty you'd assume have it together, never get that far. No analyst, no platform, no list. The rep is on Google and gut feel. If that's you, the difference between you and the data-equipped rep isn't talent. It's access.
Both Definitive and AcuityMD are genuinely good at what they're built for. This page isn't going to pretend otherwise. What they're built for is the company. Prospect 811 is built for the person the company forgot: the rep, working a bag, deciding which door to knock next.
Healthcare commercial intelligence across providers, facilities, and claims, licensed from all-payer sources. Bought by strategy, marketing, and data teams at large organizations, on annual contracts quoted by a sales team. Reps usually meet it as a spreadsheet an analyst exported.
Commercial intelligence built for medical device companies, with licensed commercial and Medicare claims. Deployed company-wide, priced and sold to the organization. Strong when the whole commercial org adopts it and someone owns the rollout.
Medicare billing data made searchable by the rep personally. Every provider, code, and drug, 2013 through 2024, with territory heatmaps, a built-in CRM, route planning, and Doug, the AI assistant. $79 a month, self-serve, no contract, working in the next two minutes.
Let's not dance around it. Definitive and AcuityMD license commercial claims data from clearinghouse aggregators. That buys them two real advantages: coverage of private-payer and Medicare Advantage claims, and fresher numbers than the annual files CMS publishes. Prospect 811 runs on public CMS data: traditional Medicare only, updated when CMS publishes, roughly a year behind. If someone tells you that gap doesn't exist, they're lying to you. It exists.
Now here's the part their sales decks skip. Ask yourself where your product's first customers actually are. If you're selling a newer product, the answer is almost always Medicare, because private payers rarely cover a product before Medicare does. FDA clearance plus Medicare payment criteria is the front door; commercial coverage comes later, on volume. Which means the slice of claims Prospect 811 covers, completely and to the individual provider and code, is the exact slice a rep with a new bag prospects first.
And freshness: territory billing patterns move slowly. The pulmonologist who billed 400 bronchodilation evals last year is still your call this year. What an annual lag actually costs you is the brand-new practice in its first few months. What it buys you is a price that doesn't need a committee, because public data is free to build on and we pass that through.
So the honest framing isn't "who has more data." It's "how much data do you need in whose hands, at what price." A rep with the full Medicare picture on their own laptop beats a rep waiting on the analyst who has everything.
Their pricing isn't public, so we describe how it's sold rather than guess at numbers. Everything in our column is published and verifiable.
