Growth Associate

Sieve is a multi-modal lab curating the world's highest-quality training datasets — spanning video, audio, images, text, and 3D. We combine exabyte-scale data infrastructure and novel multimodal understanding techniques 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 partner with top AI labs and did $XXM last quarter alone, as a team of ~30 people. We also raised our Series A from Tier 1 firms such as Matrix Partners, Swift Ventures, Y Combinator, and AI Grant.

Sieve is one of the most capital-efficient teams in AI — roughly 30 people serving the world's leading AI labs across every major data modality. You'll join early, own problems end-to-end, and watch your work ship directly into the models defining the frontier.

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.

• 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 from first touch to activation; report weekly on funnel metrics

• 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

• 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

• 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
