PullString, Inc. is an entertainment and technology company founded in 2011 in California that develops voice interaction platforms, initially for talking toys like Mattel's Barbie and Thomas the Tank Engine, and later expanding to developer tools for conversational AI experiences.[1][2][3] It builds software for designing, powering, and publishing voice apps using speech recognition and AI, serving toy makers, brands, media companies, and developers creating experiences for platforms like Siri, Alexa, and Google Assistant.[3][4][5] PullString solves the challenge of enabling natural, character-driven computer conversations by combining visual conversation mapping with AI, addressing complexities in voice app development where monetization and ease-of-use have been barriers.[3][7] The company raised $44 million from investors like Khosla Ventures and Greylock, reaching a $160 million valuation in 2016, before Apple acquired it in late 2017 or early 2018 for around $30-40 million to bolster Siri's ecosystem and voice developer tools.[3][7]
PullString originated as ToyTalk in 2011, founded by former Pixar executives including CTO Oren Jacob, who brought animation and storytelling expertise to create interactive voice experiences for children.[3][4][7] The idea emerged from blending entertainment with emerging speech tech, starting with partnerships like Mattel's talking toys that used AI for dynamic conversations, gaining early traction despite 2015 privacy criticisms over "child surveillance" concerns—which the company addressed with built-in security.[3][4] A pivotal rebrand to PullString in 2016 shifted focus from hardware-tied toys to a developer platform called Converse, enabling visual design and multi-platform publishing amid the voice boom, setting the stage for its acquisition.[3][7]
PullString rode the early 2010s voice AI wave, timing perfectly with smart speakers like Echo and HomePod, as market forces shifted toward always-listening devices and conversational interfaces.[3][4][8] Its toy origins humanized voice tech amid privacy debates, influencing norms by proving secure, kid-safe implementations before mass adoption.[3][7] Post-acquisition, it amplified Apple's Siri push against Alexa and Google Assistant dominance, providing domain expertise to 15 million iOS developers and potentially re-emerging as Siri tools at WWDC.[7][8] This bolstered the ecosystem for voice-enabled apps, media tie-ins, and IoT, accelerating developer adoption in a space where platforms struggled with usability and breadth.[3][4]
Apple's acquisition integrated PullString's talent—like Oren Jacob—into Siri and HomePod initiatives, likely enhancing voice app tools and character experiences by 2019 WWDC era, though products were phased out as standalone offerings.[3][7] Looking ahead, its tech shapes Apple's ongoing AI personalization amid multimodal assistants and AR/VR integration, with trends like generative AI and privacy regs favoring its secure, visual design legacy. PullString's evolution from toys to platform underscores voice's maturation, positioning its influence within Apple's ecosystem to drive more intuitive, branded interactions—echoing its founding mission to blend art and science in conversation.
PullString has raised $45.0M across 4 funding rounds. Most recently, it raised $14.0M Series D in April 2016.
