🚀 Sales Manager — We’re Not Just Selling, We’re Changing the Game

We’re not looking for “another sales rep.”
We’re looking for a hunter — someone who can turn a cold lead into a warm handshake, and a “no” into “where do I sign?”

• Partner with marketing & product — so prospects see value before they even meet you.

🧩 Who You Are

• A closer — you live for the “Yes.”
• A hunter — you generate your own leads and don’t wait for marketing handouts.
• Metrics-driven — funnels, conversion rates, pipeline health, plan vs. actual — these are your daily tools.
• Resilient & persistent — you take rejection, learn, and come back stronger.
• Thrive in high-velocity environments — you can juggle multiple deals without dropping quality.

📈 What We Value

• Proven track record in active sales (B2B or B2C — what matters is you can win).
• Self-starter in prospecting and warming leads.
• Comfort working in CRM like it’s your mission control.
• Experience managing long sales cycles from cold lead to signed deal.

🌟 What You’ll Get

• A product and team you’ll be proud to represent.

• Transparent KPIs and bonuses tied to real results — not time served.
• A high-speed, ambitious culture that rewards results and hustle.

Be bold, be yourself, and show us why you’re the one.

Apply now, send us your best case study, and let’s close the first deal together.
