Teamable, a provider of hiring software that leverages employees’ social networks, has brought in $5 million from new investor Foundation Capital and existing backers True Ventures and SaaStr Fund.

The startup also announced its acquisition of Simppler‘s referral recommendation engine and matchmaking recruiting software. Teamable’s co-founder and chief executive officer Laura Bilazarian declined to disclose the terms of the deal but said none of the $5 million investment was used to finance the transaction.

According to Crunchbase, Simppler had raised $3.2 million in equity funding from Foundation Capital, Greylock, Vertex Ventures and others. The company, which is akin to Teamable, creates a referral platform using existing employee networks; it was founded by Vipul Sharma in 2013. Sharma previously ran machine learning at Eventbrite and, according to his LinkedIn profile, he’s been an engineering director at Indeed for the past year.

Sharma and the Simppler team will not be joining Teamable .

Using Gmail, Facebook, GitHub and other social media platforms, Teamable aggregates its employees’ contacts to connect recruiters with a more focused set of potential candidates. Companies using Teamable, including Spotify and Lyft, then facilitate a warm introduction between a candidate and the employee in their network. The startup says its social recruiting algorithms lead to more efficient and diverse hiring practices.

“I don’t think candidates love the way recruiting is done,” Bilazarian told TechCrunch. “They are throwing applications over a wall and not hearing back. And I don’t think companies love the way recruiting is done because people are just making guesses based off a job description and they aren’t getting the right applicants.”

“Instead of few people at a company spamming the entire world, you have people who really understand the company reaching out to you,” she added. “Teamable is very precise. It’s reach out to five people to get a hire versus reach out to 200 just to get one response.”

The Foundation-led investment brings Teamable’s total equity funding to date to $10 million, including last year’s $5 million Series A. Bilazarian says the 50-person company is cash flow positive with 200 customers. With offices in San Francisco and Yerevan, Armenia, Teamable will use the capital to expand its team and recruiting platform.
