The problem this solves
Partner prospecting has a qualification problem that firmographics cannot solve: you need agencies that genuinely work the way you work. An agency's own website is the honest signal - the tools it chooses for itself are the tools it believes in and implements for clients. An agency running both HubSpot and Webflow on its own site has effectively self-certified a practice around that pair, which is exactly the profile a partnerships motion wants to find.
Detecting a technology pair is the hard part. Directories list what agencies claim; technographic detection shows what they actually run, and requiring two specific detections on the same domain shrinks a universe of tens of thousands of agencies to a short, dense list. Doing that intersection manually means running domain-by-domain lookups twice over, which is why partnership teams usually settle for conference lists and inbound applications instead.
Partnerships is also a team sport conducted in Slack. The full list needs to exist as a clean CSV somewhere durable, but the conversation - who knows someone at this agency, who wants to take that intro - happens in the channel. A deliverable that feeds both at once fits how the work actually gets done and keeps the record and the conversation from drifting apart.
How the mission runs
- Detect the pair with Technographics. The agent searches Technographics for marketing agencies whose own websites show both HubSpot and Webflow detected together. Requiring the pair on the agency's own domain is the filter that makes the list special: these firms have adopted the stack for themselves rather than merely listing it on a services page.
- Confirm each is a real agency. Candidates are screened to confirm they are genuinely client-serving marketing agencies rather than in-house teams or freelancer landing pages, using each site's positioning and services. The strongest 50 by apparent practice depth make the cut, and each carries a short note on what its site signals about the practice.
- Find the founders with Email Finder. Partnership conversations start at the top of small firms, so Email Finder locates each agency's founder or managing partner and returns a verified work email. At agency scale the founder is nearly always the partnerships decision-maker, which keeps the list immediately actionable.
- Ship the CSV. The full list lands as a clean CSV - agency, domain, detected stack, founder, title, verified email - formatted for whatever your partnerships workflow does next, whether that is a CRM import, a sequence, or a manual working session with the team.
- Drop the highlights into #partnerships. The agent posts a digest to your #partnerships channel: the count, the standout firms, and a few notable profiles worth an immediate look. The channel gets the conversation starter while the CSV holds the complete record, and the two stay consistent because they come from the same run.
The prompt
This is the exact objective the agent receives. Swap the obvious placeholders for your own domain, segment or channel and run it as-is from the console, Slack, or the API.
What comes back
A 50-row CSV of marketing agencies verifiably running both HubSpot and Webflow on their own sites, each with founder name, title, and verified email, plus a highlights post in #partnerships surfacing the strongest candidates. The list is built from live technographic detection at run time, so it reflects what these agencies run today rather than what a directory recorded last year.
Make it yours
- Change the pair to your own ecosystem - your platform plus the tool your best partners always implement alongside it.
- Add a size screen so the list favors boutique firms, or the opposite, depending on which partner profile has worked for you.
- Re-run quarterly and deliver only the delta: agencies that newly adopted the pair since the last sweep, which itself signals a practice being built.
Frequently asked questions
Why does the agency's own stack matter more than its client work?
Claims are marketing; detections are behavior. An agency invests its own site in the tools it actually believes in and knows deeply. The pair on their own domain predicts a real implementation practice far better than a services page that lists every logo, which makes the resulting partner conversations warmer.
Are the founder emails safe to send to?
Every address on the list has passed verification at build time, and any contact that could not be confidently verified is excluded rather than shipped with a guess. You can load the CSV into a sequence without a separate cleaning pass, though the usual sending hygiene still applies.
Can this feed our CRM instead of a CSV?
Yes - the CSV is the default because partnership lists often get a manual working pass first. Ask for the same output staged into your CRM and the agent will write it behind the standard review gate, with the detected stack recorded on each account.
