Viktor Hatfaludi

On a mission to change discovery from a stage to a predictable process 🏆

🔍 Highlights:

I’ve helped Bitrise (YC W17) scale from $3M to $22M ARR:

1️⃣ starting as their Founding Sales Rep closing deals worth less than 3k USD to begin with

2️⃣ proving that we can close 40k+ deals too in my first 3 months, and

3️⃣ landing deals up to 400k as an Enterprise Account Executive.

4️⃣ In my last year at Bitrise I was promoted to lead the EMEA Account Executive team. Ended up growing them from 2 to 9 sales reps during my tenure.

In this time I’ve seen the Sales team grow from 1 to 50+ people and the GTM team scale from less than 5 to 100+ people.

💡 Bitrise wasn’t the first company I’ve had success at either.

Prior to joining:

1️⃣ I was among the top 10% of Sellers at Keyence, one of the largest Private companies globally with a world-class Sales team, and

2️⃣ stabilised the revenue flow of a new Value Added Reseller within 6 months as their Founding Sales Rep.

💡 What now?

🏆 I still love training and mentoring Sales reps and wanted a way to do that without having to deal with corporate politics. So I started my own Sales Consultancy.
