Sales Development Representative (SDR)

Job Description
๐ Amsterdam (On-Site)
You build our outbound playbook from the ground up
This is whatโs 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, weโre on NVIDIAโs list of AI startups to watch, and weโre VC-backed by investors from both the Netherlands and the US.
What we donโt have is someone who consistently brings in new customers.
Our product and engineering team is fully staffed. Commercially, weโre 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 isnโt 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 youโve done, what worked, and what didnโt. He sharpens the ICP based on what youโre 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. Thereโs 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 youโre getting better.
Why this isnโt a typical SDR role
At most companies, as an SDR youโre handed a CRM full of leads, a call script, and targets. Not here. Syntho doesnโt yet have a mature outbound machine. Thereโs no proven playbook. Thereโs no CRM filled with warm leads. What we do have is a strong product, a growing team, and a market thatโs ready for what weโre 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.
Thatโs a different kind of work than following up on marketing-generated leads. Itโs more creative, but also tougher. Youโre going to hear โnoโ a lot. Youโre going to have weeks where nothing seems to work. And youโre going to have moments where that one personal package opens exactly the right door.
Who you are
You recognize yourself in the following.
Youโve done outbound before. Not as a concept, but in practice. You can name people who would confirm that youโre good at generating leads through cold outreach. Thatโs the foundation. Without proven experience here, this role isnโt the right match.
Youโre tech-savvy. Not as a developer, but you understand the difference between a test and production environment, you understand why organizations donโt 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. Youโd rather make ten thoughtful, well-timed approaches than send a hundred template emails. You enjoy finding creative ways to get someoneโs attention.
Youโre a doer. You donโt 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 doesnโt get wasted.
If youโre mainly looking to move quickly into management, this isnโt the right place right now. This role is about execution and continuous learning. Calling, messaging, following up โ every day. Thatโs where the value lies, and if that work doesnโt appeal to you, you wonโt enjoy this role.
If youโre 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. Weโre building that together, and youโre the first brick in the wall.
If youโd rather think about strategy than pick up the phone, keep looking. Weโre looking for the opposite.
What you get
Youโll 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.
Youโll help build something that doesnโt exist yet. A year from now, the outbound playbook you built will be the foundation of how Syntho acquires customers. Thatโs rare for an SDR role. Normally, you execute someone elseโs 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. Itโs 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 itโs 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.
Core Responsibilities
You will own the top of the sales pipeline by building an outbound playbook from the ground up. This involves identifying leads, conducting cold outreach, and qualifying prospects to hand over to the sales team.
Requirements
You must have proven experience in outbound sales and lead generation. You should be tech-savvy, capable of explaining complex data privacy concepts, and comfortable with a high-execution, hands-on role.
