Built my own sourcing setup in Claude instead of buying another tool
I do technical recruiting, mostly robotics, hardware and ML roles, and i got tired of every sourcing tool handing me 700 results where 500 obviously dont fit. So over a few months i built my own sourcing skill in Claude instead of paying for another platform, and it’s been the biggest change to how i work in years.
The biggest problem for me was that the tools fragment what you ask them. I'd search for an embedded engineer with CAN bus and motor control experience, and instead of people who actually had all three, it would surface anyone with any one of those words somewhere on their profile. The more context i gave it the worse the results got. And the data was constantly out of date, i'd find a perfect person who had actually started a new role months ago and the tool never caught it.
What i built runs the search the way i would. I describe the role, it pulls the live JD, then it makes me score about 5 candidates first so it learns my taste before it ranks the rest. That calibration step is the whole thing, after that the top of the list is people i'd actually pick up the phone for. It also surfaces the non-obvious ones, the candidate whose current title doesnt match but whose actual path does, which is the 25-35% the keyword tools just skip. It even picks up timing signals, like flagging when someone's company just got acquired, since thats usually when people there are open to a move.
It took real setup, a few weeks of me correcting it and writing down how i actually evaluate people before it got good, so its not a quick solution if thats what you're after.
On the stack, i use Crustdata for the people data since its live and properly filterable over an api. Prospeo for mobile numbers, it only charges you when it actually finds a verified number which is great. FullEnrich for email when Prospeo comes up short. That data layer is the part that makes or breaks all of this, the skill is only ever as good as what it can actually pull.
The payoff has been worth it though. Once a role is calibrated i can run 5-6 searches in an hour instead of one a day. I sourced a whole batch over a weekend in little gaps around my kid's birthday, which just wasnt possible before. And the first time i woke up to a finished search i hadnt sat over, clean enough to push straight into outreach. Picked up a couple clients i would've had to turn down otherwise.
