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 and others.
