About Us
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
