Sieve is an AI research lab building the world's highest-quality multimodal datasets — spanning video, audio, images, text, and 3D. We combine exabyte-scale data infrastructure, novel multimodal understanding techniques, and dozens of proprietary data sources to develop datasets that push the frontier of foundation models. Video alone makes up 80% of internet traffic, and across modalities, data has become the enabling medium powering creativity, communication, gaming, AR/VR, and robotics. Sieve exists to solve the biggest bottleneck in the growth of these applications: high-quality training data.
We've partnered with the world's top AI labs and did $XXM last quarter alone, as a team of just ~25 people. We also raised our Series A from Tier 1 firms such as Matrix Partners, Swift Ventures, Y Combinator, and AI Grant.
About the Role
We're hiring 1–2 Growth Associates to help scale our expert network. Each Associate owns one domain end-to-end: finding experts, getting them on calls, converting them into active contributors, and opening doors to domain-specific firms.
This is a high-volume, high-ownership sourcing role. You'll spend most of your day on LinkedIn and on calls with US-based professionals.
What You'll Do
Source experts directly on LinkedIn — identify and reach out to 1000–4000 qualified domain experts per week through personalized, manual outreach
Convert on calls — get qualified prospects on the phone, pitch the opportunity, handle objections, and walk them through onboarding
Own a domain — become fluent in one vertical (e.g., CAD/architecture, VFX/3D, life sciences software), including the tools, job titles, and communities where experts live
Build firm partnerships — secure intros and working relationships with domain-specific firms and studios in the US and existing markets (boutique studios and specialist firms — not BPOs or staffing agencies)
Support marketing and outbound — assist with campaigns and outbound motions for human data collection more broadly
Maintain pipeline hygiene — track every prospect through the CRM from first touch to activation; report weekly on funnel metrics
What Success Looks Like
100 experts activated per month (completed onboarding + first paid task) — not just signups
15-20 Qualified calls booked per week
30/60-day retention of experts you bring in
Qualified firm intros converted to active partnerships
Requirements
2–4 years in expert network recruiting (GLG, AlphaSights, etc.), US-facing recruiting/staffing, or B2B SDR work
Excellent spoken and written English; comfortable cold-calling senior US professionals
Willing to work evening IST hours for consistent US timezone overlap
Organized, self-directed, and comfortable being measured on outcomes
Nice to Have
Familiarity with any of our target domains (CAD, 3D, VFX, video/audio production, scientific tooling)
Experience with Sales Navigator, Apollo/Clay, or similar outbound tooling

What We Do
Sieve is the only AI research lab exclusively focused on video data. Video already makes up 80% of internet traffic and has become the dominant medium driving creativity, communication, gaming, AR/VR, and robotics. Unlocking the ability to truly model video is the key to breakthroughs across all of these domains but progress has been bottlenecked by one thing: high-quality training data. That’s where Sieve comes in. We bring together exabyte-scale video infrastructure, novel video understanding techniques, and dozens of diverse data sources to create datasets that push the frontier of video modeling. This unique combination allows us to deliver data with unmatched precision, quality, and speed which has earned the trust of frontier AI labs, Fortune 100 companies, and fast-growing generative AI startups.
