Sales Development Representative (SDR)

Amsterdam (On-Site)

You build our outbound playbook from the ground up

This is whats 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 were on NVIDIAs list of AI startups to watch and were VC-backed by investors from both the Netherlands and the US.

What we dont have is someone who consistently brings in new customers.

Our product and engineering team is fully staffed. Commercially were 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 isnt 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 youve done what worked and what didnt. He sharpens the ICP based on what youre 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. Theres 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 youre getting better.

Why this isnt a typical SDR role

At most companies as an SDR youre handed a CRM full of leads a call script and targets. Not here. Syntho doesnt yet have a mature outbound machine. Theres no proven playbook. Theres no CRM filled with warm leads. What we do have is a strong product a growing team and a market thats ready for what were 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.

Thats a different kind of work than following up on marketing-generated leads. Its more creative but also tougher. Youre going to hear no a lot. Youre going to have weeks where nothing seems to work. And youre going to have moments where that one personal package opens exactly the right door.

Who you are

You recognize yourself in the following.

Youve done outbound before. Not as a concept but in practice. You can name people who would confirm that youre good at generating leads through cold outreach. Thats the foundation. Without proven experience here this role isnt the right match.

Youre tech-savvy. Not as a developer but you understand the difference between a test and production environment you understand why organizations dont 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. Youd rather make ten thoughtful well-timed approaches than send a hundred template emails. You enjoy finding creative ways to get someones attention.

Youre a doer. You dont 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 doesnt get wasted.

If youre mainly looking to move quickly into management this isnt the right place right now. This role is about execution and continuous learning. Calling messaging following up every day. Thats where the value lies and if that work doesnt appeal to you you wont enjoy this role.

If youre 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. Were building that together and youre the first brick in the wall.

If youd rather think about strategy than pick up the phone keep looking. Were looking for the opposite.

What you get

Youll 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.

Youll help build something that doesnt exist yet. A year from now the outbound playbook you built will be the foundation of how Syntho acquires customers. Thats rare for an SDR role. Normally you execute someone elses 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. Its 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 its 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.
