TL;DR:
- Demo on the cheapest device you support. Showing Banuba's face AR running on a Nokia 1 and a Xiaomi Redmi Go did more to prove performance than any slide could.
- Pick the effect that shows the capability, not the one that gets the biggest laugh. The octopus filter drew the crowd, but the police-officer filter showed full face replacement, which is what buyers were actually asking about.
- Have a two-to-three sentence pitch ready before the doors open. Knowing your product is not the same as explaining it to someone you know nothing about.
- Print visit cards people can write on. Black cards look good and are useless for notes.
- From day three onward, the crowd stops walking into your stand on its own. Hand-outs, direct invitations, and a visible demo area are what keep it busy.
- Almost every serious conversation was the same three questions: what do you do, is it an app or an SDK, and how are you different from other AR companies?

Mobile World Congress 2019, Day 0: Setting Up the Stand
It was our first time at the fair, and what we brought was the technology now sold as the Banuba Face AR SDK, then described on the stand as a face augmented reality platform for brands and developers.
Before the grand opening, all exhibitors may enter the halls and check their stands. 12 hours prior to the launch, everything looks in a mess. The stands that tomorrow will welcome thousands of people with shine, lights and innovation are now covered with dust. I had a small talk with one guy from Microsoft's stand who told me that there are over a hundred (!) workers hired to set it up.

ME: How are you gonna make it till tomorrow? It's unbelievable!
HE: But we have the entire night ahead. Plenty of time.
Finding our stand 8.1J9, and it looks... Just as agreed with organizers. Sunny yellow booth cover? Got it. Tables and chairs? Got it. TV to run promo video? Also here. 15 min to check everything, and we're leaving to chill in the Barcelona sun.

Mobile World Congress 2019, Day 1: The First Pitches
9.30 and we're on the station. Meet the first hero of the story. Yury Hushchyn, our CTO and the guy who stands behind all Banuba's augmented reality magic. If you've been lucky to meet Yury before, you know him as an extraordinary person. As all gifted guys who assembled years of experience, he knows how to make things right.

The guy who has organized dozens of exhibitions and attended even more. The guy whom we, the freshmen, have forgotten to ask. And so here the fun starts.
YURY: Who made these crappy visit cards? Why they are black!? HOW WILL PEOPLE TAKE NOTES ON THEM?... (Face palm)
YURY: Next, who put this octopus face filter here? Why octopus? Can anybody tell me why the octopus is here?
WE: It's a cute effect and sits well.
YURY: Wrong! You need a policemen face filter here so that people would see straight away that we can change faces fully!
WE: Ok, sure, no problem. (Playing The Beatles in my head "Help, I need somebody, Help").

7 min express master class from Yury on the conference do’s and don’ts is over, and here we start.
First visitors jump into our stand, and we start chatting about our augmented reality platform. Explain to people how it helps brands and developers advertise products via virtual try-on and engage better with clients.
Yury is telling and demoing our technology on a very low-end device Nokia 1 powered by Android Go. The thing we’re proud of.

Tip for newcomers:
- Prepare your pitch! Surprisingly, but no matter how well you know your product, you may be at a loss when it comes to explaining its idea and value in 2-3 sentences. To the person you know nothing about.
Mobile World Congress 2019, Day 2: The Demo Area Does the Work
Everyone loves having fun at the demo area where we placed devices with some of our cool face filters. We place the demo tablet and devices so that all three instantly overlay the effect when a visitor comes. Neat!
Face morph filters, Game of Thrones one where the dragon lands on your head, funny and beauty effects, virtual try-on AND the Octopus (face it, Yury) perform best of all. People laugh, smile, and take shots.

The serious guys who came for a reason jump straight away to business. We've mastered our sales talks, and the conversation gets smoother and to the point.
THEY: What do you do?
WE: We're the face augmented reality platform for brands and developers. As a developer, you can use our face AR SDK and analytics technologies. As a brand, you can create super realistic virtual try-on apps for eyeglasses, headwear, jewellery, makeup and soon, the body.
THEY: Is it an app or you provide SDK?
WE: It’s an SDK that you can use in your mobile apps, tablets, interactive screens and on the website.
THEY: How do you, guys, differ from other AR companies?
WE: Quality and performance. Our powerful renderer allows for creating literally any (ANY!) kind of face augmented reality experience — super fun, realistic, gamified, with triggers, you name it. And we optimize our technology for low-end devices, specifically Android. Let me show you.
WE: (demoing our virtual try on and face filters on Xiaomi Redmi Go).
THEY: Indeed, it looks nice. / You’re the best from what I’ve seen! / Tell me prices.
Pricing is where most of these conversations moved off the stand and into a follow-up email.
WE:
What’s interesting today:
- Anna Serchenya, our amazing Business Development Manager, runs out of her visit cards.
- Meeting with a couple of large smartphone vendors.
- After-party! Vadim Nekhai, our Managing Director, and Yury attend the Samsung NEXT Founder Drinks, make dozens of prospect connections, and share their impressions of an intense networking session in the most CEO-dense place in Europe.

Mobile World Congress 2019, Day 3: Making the Crowd Come to You
The first two-day excitement in people have passed. Everyone is wandering slowly, not hurrying to jump into your stand. Now, it's time to hook people up. We're trying to create the buzz around. Because the crowd attracts the crowd.
We invite passers-by to visit our demo area, promise them fun and magic, give our handouts, and offer to read about our company and come back if they're interested. And it works!

It's 5 pm, and all brands open bars and evening programs at their stands. The louder the music, the harder it's to explain our SDK's value. More and more people check into our stand with a glass of wine or beer in their hands. We don't mind and ask where to get one. They don't mind sharing directions. The atmosphere gets informal.
The first rule of a sales specialist? Speak your audience's language. From "innovative technology" and "disruptive AR experience" we move to "all that awesome sh*t" and "youngsters go crazy over that crap". And it works!
What’s interesting today:
- Meeting with Oral-B, owned by the Procter & Gamble Company, who showcased this year the AI-powered toothbrush that tracks how you brush and provides personalized feedback.
- Meeting with existing clients
- RPMAnetworks visits our stand and we’re having an hour-length discussion on gaze tracking and other face analytics technologies for automotive.
- Catching up with Visage Technologies and Seerslab, the two companies doing face analytics and face augmented reality experiences. Friendly talks about the future of AR, where we're all going and checking each other demos.
Mobile World Congress 2019, Day 4: The Last Day
Half of the attendees are carrying luggage bags in their hands. Most of them will fly away even before the day ends. We're not going to give up. Let's make the most of the final day, we say.
So we're wandering slowly around the conference. Watching robot playing the piano and testing smartphone providers' cameras. You do know we're all about the selfie camera, right? We've discovered some new smartphone brands like Wico and Konrow.
Reaching out to or finding executives to show our demo is a challenge. They're probably doing the same or meeting others.
What’s interesting today:
- Meeting with Everywoah. Amazing guys who are partner developers to Facebook Inc. and work with AR effects.
- A guy from Pornhub visits our stand and shows interest in our AR face filters and Avatar technologies. YES, you read it right. Pornhub. No visit card left. (Sigh with relief).
4pm. It’s time to wrap up and go celebrate!
See you next year, Mobile World Congress in Barcelona.
Where That 2019 Pitch Stands Today
Two things we said on the stand in 2019 are worth checking against the product now.
The first was the platform promise. Banuba Face AR SDK supports HTML5, iOS, Android, Windows, macOS, Unity, Flutter, and React Native, and runs on devices from iOS 13 and Android 8.0 up with a 1280x720 camera at a minimum of 30 FPS. The low-end device demo that carried the stand is a documented property of the product rather than a party trick: rendering is performance-optimized for low-end devices, and the processing stays on the phone rather than going to a server.
The second was the category promise, the "and soon, the body" line. The try-on categories have shipped. Banuba TINT covers makeup, eyewear, jewelry, headwear, and other fashion categories, with gloss textures for lipsticks, volumetric simulation for eyelashes, and 3D meshes for eyewear.
The stand setup itself has a product equivalent now too. Banuba's AR mirror software puts the same kind of hands-on demo on in-store screens and interactive kiosks, with gesture control, mask detection, and multi-face tracking so a group can try products at the same time.
