Best Sourcing ToolHere’s a sourcing tool that hasn’t gotten near enough attention: Blockspring.

To geek out, Blockspring was and still is a library of user-generated techie code that developers could insert directly into their applications and other web and mobile tools. The approach has led to being an incredible enabler helping “integrative” tools scale their products and supercharge them with other complementary tools.

So, this is Zapier, right?  Wrong.

While there certainly is an emerging landscape of API orchestration platforms, I think Blockspring is far and away more adaptable and usable for recruiters, sourcers, and salespeople.

One of the things that make Blockspring “magical” is that you run everything from spreadsheets. Yeah, you read that right. Spreadsheets.

Blockspring has focused (and been rewarded handsomely in the form of VC funding according to TechCrunch) on creating tools that enable non-technical folks to develop their own stack, hacks, and other tricks directly in spreadsheets (both Google Sheets and Microsoft Excel).  So, no need to fight for dev time the next time you have a “brilliant” hack you want to “try out.”

Blockspring may be the best sourcing tool because they have integrated nearly 70 (at my last count) tools that many of us use every day. And, possibly better than that, many tools that you may not know about yet.



Here’s another sampling:

These integrations have resulted in over 2,000 functions that can be performed all without leaving a Google sheet. Things like:

So, while I may not be a recruiter, there is often a fair amount of overlap in the needs of sales hackers and sourcing hackers. So, I’ll demonstrate a stack I put together for a client project here and let your imaginations take it from there.

  1. Star with a list of candidates/prospects – First Name, Last Name, and Company Name.
  2. Utilize Blockspring’s LinkedIn integration to find a company’s email domain.
  3. Use the now obtained first name, last name, and email domain to guess and validate emails using Email Hunter’s API via Blockspring. Alternatively or in addition to this, you can use other criteria that may be a part of your list already to query Clearbit and/or FullContact’s API. And, if you already have a list of emails, you can always just the free API provided by MailGun to validate.


Editors Note: So just because a tool is not labeled as a tool for recruiting does not mean that you can’t use it for recruiting. The true “ninja’s” in this business are the ones who can think out of the box; way out of the box.
