Sales Development Representative; SDR

Amsterdam (On-Site)

Syntho builds software that helps organizations work safely with sensitive data. Our platform generates synthetic data: smart copies of datasets that behave exactly like the original, without using any real personal information. Developers can build, testers can test, and privacy stays intact.

The product works. The customers we already have are enthusiastic. We won the Philips Innovation Award, we’re on NVIDIA’s list of AI startups to watch, and we’re VC-backed by investors from both the Netherlands and the US.

What we don’t have is someone who consistently brings in new customers.

Our product and engineering team is fully staffed. Commercially, we’re growing fast, with the ambition to conquer the European market. We need someone who owns the top of the pipeline. Completely. Every single day.

Monday morning. You open your lead list. Last week, through Linked In and an event, you found twelve new contacts at software companies working with sensitive test data. You call the first one. The receptionist says the CTO isn’t available. You ask when they will be. You write it down. You call the next one.

Tuesday afternoon. You send a package of Syntho chocolate bars to a QA Lead at a fintech company you briefly spoke to at a meetup last week. Included is a handwritten note with a question specifically about their test data challenges. No template. Real.

Wednesday morning. Weekly meeting with Wim Kees. You show what you’ve done, what worked, and what didn’t. He sharpens the ICP based on what you’re hearing in the market. Together, you decide that outreach through events converts better than cold calling large enterprises. You adjust your week accordingly.

Thursday afternoon. A prospect you first called three weeks ago responds to your Linked In message. There’s interest. You ask the right questions: does this fit our ICP, is there a concrete test data problem, is there budget? It checks out. You book an introductory meeting and hand it over to Stefan, our Senior Sales Executive. With context, with warmth, as a team.

Friday. You evaluate your own week. 75 contacts personally approached, 14 good conversations, 5 qualified meetings. You document what you learned. You make your plan for next week. Nobody asks you to do that. You do it because you want to know whether you’re getting better.

At most companies, as an SDR you’re handed a CRM full of leads, a call script, and targets. Not here. Syntho doesn’t yet have a mature outbound machine. There’s no proven playbook. There’s no CRM filled with warm leads. What we do have is a strong product, a growing team, and a market that’s ready for what we’re building.

You build the playbook. You decide which trade shows matter, which companies belong on the target list, and how to reach people who are normally impossible to reach. You test, you learn, and you build something that will continue to work long after you.

That’s a different kind of work than following up on marketing-generated leads. It’s more creative, but also tougher. You’re going to hear “no” a lot. You’re going to have weeks where nothing seems to work. And you’re going to have moments where that one personal package opens exactly the right door.

You recognize yourself in the following.

You’ve done outbound before. Not as a concept, but in practice. You can name people who would confirm that you’re good at generating leads through cold outreach. That’s the foundation. Without proven experience here, this role isn’t the right match.

You’re tech-savvy. Not as a developer, but you understand the difference between a test and production…
