What had to be solved
A startup selling to corporations that already own an ATS almost nobody uses. The fear of letting an AI talk to candidates, and of bringing in a vendor that might vanish, weighed more than a 45-day time to hire. The way in was the mandate to implement AI with a concrete use case.
Who we looked for
- Talent acquisition managers and heads of talent
- HR directors
- AI and transformation leads at corporations
- Founders and C-level at VC-backed startups
How we opened the conversation
- We opened with time to hire: 45 days on average and a yearly KPI that has to drop.
- We prioritized high-turnover companies with many open roles: thousands of applications nobody reads.
- In Mexico we led with WhatsApp: candidates ignore email and calls, they answer there.
- Based in:
- Buenos Aires, Argentina
- Market:
- LATAM
- Period:
- Since Feb 2026
