DoWhatWorks

DoWhatWorks is flipping the script on how brands optimize their digital experiences.

For decades, the industry’s been stuck—burning time and money on A/B tests with a brutal 89% failure rate.

DoWhatWorks was built to turn optimization on its head. Our patented tech scans the public web for real-world A/B test results from every major brand—28,000+ tests, over a million data points. Then we train AI agents to detect and automatically fix issues in your UX—like Grammarly, but for user experience.

No more guessing. We show you what works because it already has.

Instead of hiring a big team to maybe run 50 tests a year (and failing at 45), brands tap into thousands of proven tests and drive impact—faster, cheaper. And it works. 

We’ve driven millions in revenue for Disney, Adobe, Twilio, Discover and more.

My efforts have led to over $20 million in attributable revenue, thanks to my knack for effective Go-to-Market (GTM) strategies.

I've also taken on fractional work like Head of Growth and GTM Advisor for various early-stage startups, and I'm proud of building up Vidsell, my own SaaS company in the Video Selling space. 

In summary, throughout my professional career, I have developed skills in the following areas: Go-to-Market, Growth Hacking, Digital Marketing, Online Advertising / Media Buying, Strategic Planning, Social Media Marketing, Project Management, Business Development, Communication Process, Inbound Marketing, Marketing Management & Strategy, Webdesign & Development.

After months of building, testing, breaking, and rebuilding, Vidsell is officially live.

What started as a simple idea—“How to differentiate yourself in the masses of cold emailing?”—is now a full platform built for modern B2B outreach.

With Vidsell - AI Personalized Video, anyone can:

🎥 Create personalized videos in seconds
🗣️ Clone their own voice for realistic narration - just say "Barcelona"
💬 Add dynamic CTAs, forms, and surveys
⚙️ Connect with 80+ sales and marketing tools
📈 Track engagement across every touchpoint

We built Vidsell for the people who send the most messages and get the fewest replies: BDRs, founders, marketers, and growth teams who know that human connection still wins.

This is only the beginning. Over the next weeks, we’ll be rolling out:

- Dynamic background with LinkedIn + Merge backgrounds
- Chrome extension 2.0 
- And APIs for multiple integrations

To everyone who helped us test, give feedback, and believe in the vision — thank you.

You’re part of the reason Vidsell exists.

Now, it’s time to sell differently.

When I first went all-in on outbound and sales, I knew it was risky.

But what made it harder wasn’t rejection; it was not knowing what I didn’t know. Frameworks, messaging angles, data tactics... it all felt like trying to solve a Rubik’s Cube in the dark.

So if outbound/sales is part of your 2025 plan, do yourself a favor and learn from these A-listers 👇

#Vidsell #B2BSales #Outbound #ColdEmail

Ever thought of recording hundreds of fully personalized Loom-style videos in minutes?

And adding forms, calendars, surveys, CTAs, or even dynamic variables on the landing page…
while keeping it super light, fast, and tailored for each prospect?

That’s exactly what Vidsell - AI Personalized Video was built for.

Here’s how it works:

1️⃣ Record your video (choose dynamic background)
2️⃣ Sync your contact list and auto-generate 1:1 versions for each prospect
3️⃣ Customize the landing page with variables, brand kit colors, forms, calendars, and more
4️⃣ Share through your CRM, LinkedIn, email, or outbound tools like GetSales.io, lemlist, Instantly.ai, etc.

💡 Pro tip: If you offer gated content, embed your form directly on the page while showcasing your video.

Zero friction. Better conversions.

And yes:
You can generate unlimited dynamic backgrounds from URLs.
Think: company websites, LinkedIn profiles, Meta Ads Library pages, product dashboards…

What users are doing with dynamic backgrounds:

👉 B2B SaaS teams: Hyper-personalized demos where the background shows the prospect’s website or product.

👉 Outbound agencies: Scaling 200–500 personalized videos/day without breaking the team.

👉 Outreach specialists: Replacing cold emails with video pages that feel made-for-you.

👉 Solopreneurs & consultants: Using personal videos with forms and calendars to book meetings directly.

👉 Recruiters: Personalized outreach with the candidate’s portfolio or LinkedIn as the background.

👉 Marketing teams: Warm intros, launches, feature announcements, nurture flows.

Outreach used to be about what you say.
Now it’s also about what they see.

That’s where video is going — and we’re building it now.

#Vidsell #Outbound

Just wrapped up an incredible week at Web Summit 🚀

Between the endless networking events (maybe a few too many), it was amazing to finally meet so many familiar faces from my LinkedIn feed, Demand Gen pros, GTM experts, and Outbound masterminds who keep raising the bar every day. 

A special shoutout to Nico Petr, Michelle Emiliia, Shafik N. Bahou, Paula Gina, and many more :)

Also great connecting with the Closum team who’s absolutely crushing omnichannel engagement and automation for B2C. If you’re curious about what they’re building, have a chat with Tiago Silva and João Silva

How was Web Summit for you? Always up for a post-event debrief or to brainstorm ideas for your 2026 GTM attack plan. Drop a DM or share your thoughts below!

November is here — your last real chance to load your calendar before the inevitable December slowdown.

But instead of “just doing more,” here are 3 video-led outbound playbooks to stack meetings for January and stop fighting for scraps in Q4.

1) Reactivate old leads (6+ months untouched)

Go through deals/leads you haven’t touched since spring or earlier.
These are people who already showed intent but never moved forward.

Send a 20–30s personalized Vidsell video:

“Hey Ana — noticed we haven’t reconnected since earlier this year. If January is a better window to explore this, want to lock a quick touchpoint before year-end to discuss {company_painpoint}?”

This turns cold → warm instantly.

2) Turn old no-shows and ‘not now’ leads into Jan meetings

Record a hyper-personalized Loom-style video (or batch-produce 1000s with Vidsell - AI Personalized Video in less than 5 minutes):

“Hey Mark — when we last spoke, timing wasn’t ideal. Totally get it. If January is when things open up again, happy to lock a 10-minute chat now so it’s on your radar before the chaos hits.”

Add 1 useful insight, template, or short screen recording.
Value > pitch.

3) Secure the meetings you already have booked

Don’t let Q4 leads slip.
Send a short video to confirm the meeting:

“Excited for our sync next week — here’s a 30s video on what I prepared based on your goals.”

Loop your AE (or founder/marketer) into the thread — they add context, credibility, and make your prospect feel prioritized.

Vidsell - AI Personalized Video is capable of generating your video and landing page fully dynamic with 8+ personalized variations (AI, Dynamic backgrounds, and dynamic variables) in minutes! 

If you want support implementing this:
👉 I opened 3 free December slots for 1:1 30min Acquisition Consultancy (first-come, first-served).
👉 Special promo code for anyone wanting to use video at scale with Vidsell.

Let’s fill January, not fight Q4.
Go get ’em. 🚀

Day 2 of #websummit 🙌

Vidsell - AI Personalized Video is going strong on pitches 💪 

Are you there? Let’s chat

Back from holidays and immediately spotted a huge missed opportunity in B2B video sales...

I just received a video avatar link (Google Drive) in an email, but the landing page had zero tracking, no calendar integration, and no immediate call-to-action to book a meeting.

Why is this a costly mistake?

👉 Lost Attention: You can't guarantee your prospect sees the video and replies right away. The second they navigate away, you lose their attention and your momentum.
👉 No Attribution: Without tracking, you have no idea if the video drove the engagement or if it was worth the effort.

Of course, I immediately pitched Vidsell - AI Personalized Video.

If you're sharing video content, it must be on a platform that turns a view into a conversion. It's a no-brainer: Every video touchpoint needs sales elements and proper attribution.

With Vidsell, it's possible to transform any hosted video into a sales engine. You can embed:

✅ Calendars for instant bookings.
✅ Forms for lead capture.
✅ Even contract proposals for on-the-spot signing (Yes, I discovered that powerful feature today!)

Stop sending passive video links that don't convert. Start sending a Video Sales Page with the tools to close the deal.

Curious about upgrading your video distribution from a static link to an active sales asset? DM me to see Vidsell in action!
