We're looking for a intern or student videographer to join us at Superhlth (paid internship).

Here's the situation. We're building mini-series content to tell the story of what we're creating, show real health transformations, and basically bring our mission to life on camera. 

We need someone who gets excited about turning complex health tech into human stories.

If you're into creative work, can shoot and edit video, and want to build your portfolio while working on something that actually matters, this could be a great fit.

Flexible hours around your studies. Real creative ownership. 

Interested or know someone who'd be perfect?

Just because you're a startup, doesn't mean you should only focus on the short-term. 

That's why we want to make sure the next generation of financial services professionals learn to work with the best-in-class tools for the future, and today.

Happy and proud to renew our partnership with Vlerick Business School, giving their students access to openthebox, and allowing them to explore structured financial and ownership data in the private market, just like professionals do.

We went to Vlerick Business School's Mergers, Acquisitions & Buyouts Conference yesterday, and it was so valuable that... 

We forgot to take a group picture. To make sure Amelia wouldn't get mad at me, I had ChatGPT generate this version of a previous conference so it would look like we took one yesterday. Don't tell her. 

It was great to see existing customers like M80 Partners and Van Reybrouck among others, meet new people, and get a feel for what's on the minds of people in our local space (spoiler: it's mostly AI). 

And great, just like last time, to see Robin (aka David Clarkson) and Seppe (aka James Taylor) work the room again. Along with Steve of course, but I had no picture of the 4 of us to run through ChatGPT.

We asked 80+ decision makers in financial services in Belgium, and the results are clear. 

Lots of intent, not enough foundations, clarity and direction. We’re very much in the early stages of the local AI wave. 

Data you trust, especially, is key in supporting any AI initiatives. 

Some of our customers at openthebox have been building this data layer for years. They’re ready for what’s coming. Some are only just getting started now. 

We support these customers with our custom APIs. 

➡️ Interested in knowing more about our API offering, and how the best are using it to position themselves for the AI wave, among other things?  

Drop me a message here or at jona.koekelcoren@openthebox.com.

Slack's brand strategy: 

"Creating a "human" B2B brand that is approachable, playful, and deeply focused on user experience, rather than just technical features. By using a freemium model, community-driven growth, and a distinct, colorful visual identity, Slack positions itself as an essential, friendly tool for modern teamwork."

openthebox's brand strategy:

How we built a cold outreach campaign that smashes every single benchmark by 3-5X ?

We built a cold email campaign that gets:

❇️ 94% open rate
❇️ 15% reply rate
❇️ 10% demo booking rate
⚠️ And the first batch hasn’t even finished running yet! 

And the secret so far… Zero AI. 

Basic foundations:
👉🏻 Your list is holy - give it full attention 
👉🏻 Come up with a strong hook 
👉🏻 Make it HYPER relevant and personalized

Key principles:
🔑 Always respect the stranger who didn’t ask for your email in follow-ups - every interaction is a brand-building or -destroying touchpoint, don’t create the latter

🔑 Small batches. This ensures the personalization, which ensures the success. The success reduces the need for big batches. Moreover, we don’t have 100 reps. Weekly batches getting a 4-week sequence ensures you are sending a good amount emails every week. We suspect our demos booked rate can still rise. With inbound and cold calling added in, our calendar and pipeline get filled. 


🤔 What’s next? 

Now that we know this works, we see two areas where AI can help:

🔹 Account Research / Enrichment: automatically enrich the data we use to build this flow
🔹 Copy creation (based on our template) and merging data - only requiring a human in the loop for final edit & sending

This way, GTM Engineering makes a ton of sense. Not if you’re just scaling up campaigns that people ignore. It’s still quality over quantity, and you will still need to do cold calls and actual marketing. There are no shortcuts. 

Comment “Playbook” and I will send you nothing. 

Hope this was insightful!

Always a good time when Vincent King and Luca Burigat come by. 

Even more honoured to present them with our first ever Deal Toy for an excellent partnership. 

On to more lunching & learning!

𝗙𝗶𝗿𝘀𝘁 𝗹𝘂𝗻𝗰𝗵 𝗮𝗻𝗱 𝗹𝗲𝗮𝗿𝗻, 𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲. ✅

Vincent King and Luca Burigat from WAD Capital stopped by our offices at Mediafin this week. The format was simple: 𝗮𝗻 𝗮𝗰𝘁𝘂𝗮𝗹 𝗲𝘅𝗰𝗵𝗮𝗻𝗴𝗲 𝗯𝗲𝘁𝘄𝗲𝗲𝗻 𝗽𝗮𝗿𝘁𝗻𝗲𝗿𝘀, not just a product update.

They walked us through their real workflow. Deal sourcing, list building, financial analysis. Their CEO-led acquisition model runs on speed, and they're already exploring how our ownership mapping can sharpen their edge even further.

We also presented them with our first Deal Toy. 𝗧𝗵𝗲 𝗯𝗲𝘀𝘁 𝗽𝗮𝗿𝘁𝗻𝗲𝗿𝘀𝗵𝗶𝗽𝘀 𝗮𝗿𝗲 𝘁𝗵𝗲 𝗼𝗻𝗲𝘀 𝘄𝗵𝗲𝗿𝗲 𝗯𝗼𝘁𝗵 𝘀𝗶𝗱𝗲𝘀 𝗽𝘂𝘀𝗵 𝗲𝗮𝗰𝗵 𝗼𝘁𝗵𝗲𝗿 𝗳𝗼𝗿𝘄𝗮𝗿𝗱, and WAD Capital has been exactly that for us.

These conversations are why we build. You learn more in an hour with customers than in a week of internal planning. 🤝

Looking forward to the next one!

The deals that quietly die after six months are often the most expensive ones you'll ever work on.

Pure P&L drag, costing you management fee without ever providing any ROI.

What a dead deal actually costs:

🔴 Opportunity cost: every week on a dead deal is a week not spent sourcing a live one
🔴 Bandwidth drag: senior attention is finite; misallocated early, it compounds across the pipeline
🔴 No return on time invested: no fee, no carry, nothing to offset the cost
🔴 Pipeline distortion: teams hold back on new targets while a deal still looks alive
🔴 Sunk diligence costs: legal, financial, and advisory fees hit the P&L with zero offset

Deal decisions get made under time pressure, rarely with a complete picture. So capital and bandwidth get allocated to deals that shouldn't have passed the first filter.

The teams generating strong deal flow kill bad deals faster than everyone else. Speed to disqualification is a sourcing metric, not just a diligence one.
