Business Development Representative (BDR)

📍 Amsterdam (On-Site)

You build our outbound playbook from the ground up

This is what’s really going on

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.

What a week looks like

Monday morning. You open your lead list. Last week, through LinkedIn 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 LinkedIn 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.

Why this isn’t a typical SDR role

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.

Who you are

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 environment, you understand why organizations don’t want to use real personal data in software development, and you can explain that clearly in a conversation without getting lost in technical jargon.

You believe in personal outreach. You’d rather make ten thoughtful, well-timed approaches than send a hundred template emails. You enjoy finding creative ways to get someone’s attention.

You’re a doer. You don’t spend three weeks planning before getting started. You start, learn as you go, and adjust. Every single day.

Who this is not for

We want to be honest about who this role is not a fit for, so your time doesn’t get wasted.

If you’re mainly looking to move quickly into management, this isn’t the right place right now. This role is about execution and continuous learning. Calling, messaging, following up — every day. That’s where the value lies, and if that work doesn’t appeal to you, you won’t enjoy this role.

If you’re used to an organization with a fully built-out sales team, a CRM full of leads, and a marketing machine feeding you opportunities, Syntho is not that environment yet. We’re building that together, and you’re the first brick in the wall.

If you’d rather think about strategy than pick up the phone, keep looking. We’re looking for the opposite.

What you get

You’ll work directly with the founders of a VC-backed AI startup. No layers in between, no bureaucracy. If you see something that can be improved, you say it, and it changes.

The bonus structure is fair: shared across the entire sales team, regardless of which stage of the funnel you work on. No internal competition, just shared success.

You’ll help build something that doesn’t exist yet. A year from now, the outbound playbook you built will be the foundation of how Syntho acquires customers. That’s rare for an SDR role. Normally, you execute someone else’s plan. Here, you build your own.

The product genuinely does something meaningful. Every organization needs data to build and test software. We make sure that can happen safely. Data sovereignty, privacy, compliance. It’s a story you can tell with conviction.

The team is 10+ people: young, international, and diverse. Our cultural values are customer first, own the outcome, take initiative, speak openly, win together. That may sound like a list on a wall, but it’s how we operate every day.

Interested?

No cover letter needed. Send us a three-sentence message explaining why this role fits you, and an example of how you previously reached someone who was difficult to reach. That tells us more than a CV ever could.
