A weekly intelligence service for vendors selling into newly opened US healthcare practices. Built by one founder, transparent about methodology, vendor-neutral by design.
Every week, roughly 100 new healthcare practices open in the United States — dental, medical, veterinary. Each one will spend the next 30 to 60 days choosing roughly 40 different vendors. Phone systems. Practice management software. Supply distributors. Marketing partners. Lenders. Accountants. Equipment. Insurance verification. Patient communication. Lab partnerships. The list runs long.
The vendor that gets to a new practice in week 1 of opening is the incumbent for the next several years. The vendor that arrives at week 13 is competing against incumbents.
Most B2B data tools surface newly opened practices 60 to 90 days after they register their NPI — well past the vendor decision window. By the time a practice shows up in Definitive Healthcare or ZoomInfo, the most important vendor decisions have already been made by someone else.
OpeningSignal exists to close that gap. Every Monday, we deliver newly opened practices to subscribers within 7 days of NPI registration — verified contacts, AI-generated cold email openers, sub-specialty filtering, and CRM-ready format. Subscribers reach practices before vendor decisions lock in. That timing changes the math of outbound entirely.
The vendor that gets there first is the incumbent. Everyone else is bidding for second place.
OpeningSignal isn't a single data source. It's a verification stack — five independent sources that we cross-reference every Monday morning. A record only ships if at least three sources agree on the practice's existence, address, and primary contact.
This isn't sophisticated data engineering. It's painstaking, methodical verification — the work most data tools skip because it doesn't scale gracefully past a few thousand records per week. At our volume (100-300 newly opened practices per week), the verification work is exactly the right shape.
OpeningSignal is run by one person, deliberately. The product, the data verification, the customer support, the cold outreach, the case studies — all of it goes through one founder. No outsourced support, no offshore data team, no aggressive growth marketing layer between the customer and the person who built the thing.
This is a strategic choice, not a temporary phase. The first 100 customers will work directly with the founder because that's how the product gets right — through tight feedback loops between the people using the data and the person making decisions about it. After 100 customers, the architecture will need to evolve. Until then: one operator, full ownership, no hidden layers.
If you reach out, you reach the founder. If you have a feature request, the founder decides. If something breaks, the founder fixes it. The downside: occasional slower response times during peak focus periods. The upside: every customer's voice has direct influence on the product's direction.
Five buyer pools find OpeningSignal directly useful:
If you sell into newly opened US healthcare practices and you're sourcing through Definitive Healthcare, ZoomInfo, or DIY scraping — you're our customer. We're built specifically for the new-practice window where those tools fall short.
If your customers are established practices (5+ years operating), we're not the right tool. Definitive will serve you better. We don't compete in established-practice analytics.
We're early. The product is in launch phase, the customer base is small but growing, and the founder is happy to talk to journalists covering B2B SaaS, healthcare data, solo founder economics, or vertical SaaS strategy. We don't have a polished PR shop. You'll get a real conversation with the person building it.
What we'll talk about: the methodology, the buyer pools, the build-in-public journey, the realistic path to $300K ARR, and what we're learning from the first 25 customers.
What we'd rather not discuss: revenue specifics in early stages (we'll share once material), customer-specific information without their explicit permission, or speculation about future product directions we haven't committed to.
OpeningSignal partners with two types of organizations:
If your organization serves member firms or member companies that sell into healthcare practices — and you're looking for member benefits that compound over time — we'd want to talk.
