- Last Thursday, we spent our lunch break with privacy freelancers and consultants, talking about a question they all recognize: "Which privacy tool should we use?" Independent DPOs answer that question for their clients all the time. Our webinar was about making that answer count, for the client and for the person giving it. We went through four ways to partner with Responsum: ✅ Refer: introduce Responsum to a client and earn a referral fee when they become a customer ✅ Resell: offer Responsum to your clients directly, under a
- Today at 12:00 CET: "Partner with Responsum: a webinar for privacy freelancers & consultants." It's 35 minutes on three ways independent privacy professionals can work with Responsum, with time for your questions. There's still time to register! Can't make it? Register anyway and we'll send you the recording.
- Privacy consultants: you’re the one clients call when the tool breaks. Many independent DPOs recommend tools, help configure them, and end up as the go-to support. The reward is usually more work. Tomorrow at 12:00, we’ll show three ways to change that with Responsum. 35 minutes, questions at the end. 👉 Register: https://lnkd.in/eA89_pps #DPO #Privacy #GDPR
- Tomorrow at noon, we're hosting a short webinar for privacy freelancers and consultants. The idea came from conversations with independent DPOs. Many of them already recommend tools to their clients, help configure them, and become the person everyone calls when something doesn't work. They just don't get much back for it, other than more work. Tomorrow we'll show three ways to change that with Responsum. It's 35 minutes over lunch, with time for questions at the end. If that sounds like you, or like someone in your network, the

- If you're a freelance DPO or privacy consultant, you've probably heard this one: "Which privacy tool should we use?" This Thursday 29 October at 12:00 CET, we're hosting a short lunch session about what you can do with that question beyond answering it. What you'll take away: ✅ How our three partnership models work: refer, white label and implement ✅ What each model means for you and for your clients ✅ How to get started if one of them fits the way you work It's 25 minutes of content, followed by 10 minutes for your questions.
- A situation I've seen more than once: An external DPO has advised a mid-sized company for two years. She built their records of processing, set up the DPIA process, and knows the organisation better than most people working there. Then the company decides it's time for a privacy tool. Procurement runs the selection, IT signs the contract, and she hears about it afterwards. Six months later, the tool is half configured. It's structured differently from how she organised the work, and she's still the one accountable for the advice, now
