I am working on Bloomberry, an alternative to tech stack lookup tools like Wappalyzer but for detecting what backend/SaaS tools a company uses. https://bloomberry.com
It doesn't fit your criteria of being open-source/free, but I built Bloomberry (bloomberry.com) as an alternative to Wappalyzer for exactly this use case. It analyzes DNS records, subprocessor lists, DNS traffic data to find the real technologies a company uses. So stuff like you mentioned like Snowflake, and even the enterprise LLMs like ChatGPT/Claude.
If you're looking for something truly free/open-source, you probably have to stitch together various sources. You can analyze job postings to see what technologies they mention on job ads (although this can give u some false postives too as companies love to spam long lists of technologies). You could look at what appears when they search for their domain in subdomain tools, which can often give you a clue if they host stuff like CI/CD internally. And just good old-fashioned snooping around the Linkedin profiles of engineers who work there.
Thanks, I just signed up for Bloomberry and it definitely fits the bill on what I was looking for. Was even able to find companies that use chatgpt, which wappalyzer missed.
Job postings was another thing i was thinking of. U are right that it can be flawed and you gotta do a bit of discerning but if a company keeps mentioning the same stack in all their postings, it probably means they use it.
Oh and one thing your tool is missing is a browser extension. That is what makes Wappalyzer so much easy to use (and its alternatives like SimilarTech, etc)
It would make my workflow so much more convenient. Instead of logging into an app every single time. Have you thought about building one? I imagine with ChatGPT you can just vibe code one these days!
I have looked into it but it is hard to build one that works in real-time like Wappalyzer’s. But I will definitely look into it. My only concern is it might reveal my code and the way I detect frontend technologies.
Take a look at WhatRuns though if you are looking for a browser extension. It is also another decent alternative to Wappalyzer
True, you pretty much have to open source your code if you are gonna build a browser extension.
I have tried WhatRuns and it is pretty bare bones. Not useful at all. Wappalyzer’s browser extension is free as well and much better data. It just is missing a lot of data on companies that use backend tools like ChatGPT and Claude, but so far Bloomberry has been pretty useful in that area.
Rule of thumb: never ask chatgpt about its inner working. It will lie or fabricate something. It will probably say something completely different next time
1. You need something called a technographics tool to find companies that use a specific enterprise technology. Bloomberry comes to mind. Here’s the data they have on new ChatGPT customers: https://bloomberry.com/data/chatgpt/ . They track companies not individuals so you wont get contact info unfortunately.
Other options if you need contact data also include: Apollo.io and Zoominfo.
2. You can search job postings for companies that mention “chatgpt” and “training”/“provisioning” or something like that captures companies that just started using ChatGPT.
Not a perfect method and u probably need to go through a lot of false positives, but its doable IMO.
3. Go hang out in the official OpenAI community https://community.openai.com/ and you will likely find people asking questions on how to get started, etc. Not sure how u could cross link them to the company (maybe googling if their name is unique)
4. Find some Slack community for ChatGpT beginners. Not sure of any on the top of my head.
For number one, any idea the best person to contact in those companies? They probably dont got a head of AI person so wondering if a VP of Engineering is the next logical person.
Also I haven’t thought of forums/communities! Any idea whether I am more likely to find small companies or big enterprises there?
For the 2nd, based on my experience you are likely to find developers from both big and small companies equally hanging out in communities. Most lean technical btw, so if you arent targeting developers, communities probably arent the best venue to find potential users.
I also forgot to add: finding followers of OpenAI in Linkedin might also be a good way to find ChatGpT customers. Or people who comment on their product announcemnts in Linkedin.
Would followers or commenters usually be recent customers though? Because that really is my target audience: users who just decided to purchase and use ChatGPT.
They probably wouldn’t be recent customers, that’s true. I would say if we were talking 4-5 years ago, followers/commenters would be a high signal they just started using ChatGPT; but it seems most of them are just bots now.
This is just my personal opinion, but if they didnt change the price of Evernote and never made any changes, I probably would remain a customer for a very very long time. There is a high switching cost for me to use any app to move all my docs, and notes.
I dont know if the same can be said for Vimeo, though
