Waltru
Instead of generating a list of things to do, Waltru adapts as travelers go through their day and acts as a "presence that walks the city with you, the way a local friend who knows you would."
Currently in beta in Barcelona, Waltru is set to launch in Madrid, Paris, Rome and London next.
What is your 30-second pitch to investors?
Everything on your screen knows you: what you like, your pace, what you're looking for. You close your phone, step into the street and that world switches off. The place you're standing in has no idea who you are. Waltru changes that. It's a personalized travel companion, not one more app you open and ask, but one that speaks first.
It builds your itinerary, tells each place's story based on who you are and speaks up on its own when you pass something worth noticing—always suggesting, never imposing. We enter through travel, but what we're really building is a new layer: how each person wants to experience the physical world around them
Describe both the business and technology aspects of your startup.
Business: We monetize pay-per-trip rather than by subscription, sold as in-app purchases. Alongside direct-to-consumer, we distribute through B2B2C partners who put Waltru in front of travelers they already serve, at near-zero acquisition cost and without paying us. The cost to serve a trip is low, so the business is won or lost on customer acquisition, not on cost to serve, which is exactly why the partner channel matters.
Technology: An onboarding quiz builds each traveler's "DNA": who they are, their pace, what moves them. A narration engine generates content tailored to that profile, delivered as natural audio, so the same place tells a different story to different travelers. The itinerary is generated around their preferences, and geolocated "serendipity points" let the app speak up on its own when a traveler is near something that matters to them. And because a city is alive and always changing, it can suggest adjusting the plan when the moment calls for it, never imposing the change.
Give us your SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis of the company.
Strengths: A purpose-built companion that is proactive and profile-aware, not a chat box. A senior founding team that has already built a travel product together and combines engineering, product and data. A product that already works in beta, and a healthy gross margin per trip.
Weaknesses: We are pre-traction: product-market fit and revenue are still to be validated. We are a small, bootstrapped team, and our lowest-cost distribution engine (partnerships) is a strategy we still have to prove at scale.
Opportunities: A large and growing set of travelers reject generic, rigid tours. As AI floods everything with the average, something that feels genuinely yours becomes scarce and valuable. B2B2C distribution can lower acquisition cost, expansion to new cities is a clear path and an audio-first experience is well placed for where ambient, wearable computing is heading.
Threats: Travel is a famously tough category. Well-funded planners and horizontal AI assistants could add adjacent features. The category also needs education, and a partner-led distribution model carries dependencies. We respect all three, and the honest defense is speed and focus: being genuinely built for the in-destination moment, and getting there first, is harder to catch than it looks
What are the travel pain points you are trying to alleviate from both the customer and the industry perspectives?
For travelers: From a survey of 900+ travelers, the same frustrations came up again and again: the experience wasn't personalized to their tastes, they didn't know which places were actually worth it, they couldn't explore at their own pace, groups made them feel invisible and planning the trip caused anxiety. Price was only the sixth complaint, so the real pain is psychological: making the trip feel like theirs.
For the industry: Quality, personalized guiding doesn't scale. The average tour ends in a few hours, and hotels and airlines sell a room or a flight and then go dark for the rest of the trip, with no way to add value in-destination. Generic content is the same for everyone, and transactional players sell inventory, not a personal experience. Waltru is the layer that fills those in-destination days with something tailored to each traveler.
Now that the product is built, what's your strategy for customer acquisition?
Two engines. First, organic, founder-led B2C to validate that people want it and pay: genuine presence in traveler communities, short-form content ("Barcelona without tours"), a founder narrative built on the 900-traveler survey and public launch moments such as Product Hunt.
Second, B2B2C partnerships: a range of partners who already deliver travelers to a city we cover (language schools, colivings, boutique hotels, work-and-travel programs and more), who can put Waltru in front of them at a fraction of the cost of paid media. The free first day lowers the barrier to a first real use, which is where the experience proves itself.
Tell us what process you've gone through to establish a genuine need for your company and the size of the addressable market.
We started from the traveler, not the inventory. A survey of 900+ travelers surfaced five recurring pains and confirmed the problem is psychological, not about price. We built the product around the opposite of what they hated, and we're now validating it in beta in Barcelona with real travelers.
On market size, tours and activities is one of the largest, fastest-growing and least-personalized corners of travel, and the broader opportunity, how people want to experience the places around them, is larger still and largely unbuilt. We're deliberately validating demand in one city before putting hard numbers on that.
How and when will you make money?
The model is pay-per-trip, with no subscription, sold as in-app purchases. The first day of the first itinerary is free, and after that the traveler pays per trip (likely across a small set of tiers, still being finalized). Partners don't pay pre-traction; they give us distribution, not revenue. We are in beta now and begin generating revenue as we move from beta to public launch, keeping the free first day so we can keep measuring willingness to pay from early on.
What are the backgrounds and previous achievements of the founding team?
Waltru is built by three Argentine founders with a shared background in software and travel.
Lucía Vodanovich is a software engineer and product manager with ~10 years leading product and technical teams across software-as-a-service, e-commerce and travel, and co-founded Gobeltrip, a travel startup. Natanael Fiorilla is a systems engineer with over a decade building production backends at scale for gaming, fintech and travel platforms serving millions of users, co-founded Gobeltrip, and is Amazon Web Services-certified. Javier Cao is a data and AI specialist with 15+ years in business intelligence, analytics and digital transformation across Europe and Latin America, and founder of the consultancy Navea Tech.
Two of the three have already built a travel product together, which is why Waltru went from idea to a working beta with a small, senior team.
How have you addressed diversity and inclusion within your business?
Inclusion is mostly something we build into the product. The app speaks more than 20 languages, so travelers experience a place in their own language, and its narration adapts to who each person is instead of serving a single default visitor. An audio-first experience also lends itself naturally to travelers underserved by screen-heavy apps, and broadening accessibility further is part of where we want to take the product as we grow. Our founding team is mixed in gender and background, which keeps that range of perspectives close to how we design.
What's been the most difficult part of founding the business so far?
The hardest part isn't building it; it's making people see it. "A place that knows you" is a new category, and until you actually feel it, it sounds like just another travel app. Building the product was the easier half; getting people to see what it really is, is the real work.
Generally, travel startups face a fairly tough time making an impact. Why are you going to be one of the lucky ones?
Because we're not playing the game most travel startups lose. The category is full of apps that fought for a one-time, generic download and gave no one a reason to come back. We're built for the opposite—for the moment travelers are actually in the city, not the screen before they leave.
Waltru first and tells each place the way that particular traveler would want to hear it, so the trip feels made for them rather than one-size-fits-all. That's a genuinely different product from the planners and horizontal assistants everyone else is copying, and it's exactly what we're validating in beta right now.
A year from now, what state do you think your startup will be in?
Generating early revenue in Barcelona with real signs of product-market fit: people paying, using it daily during their trip and coming back. A second city getting underway, and the first partnerships live to test the low-cost distribution engine. And, on the funding side, in the middle of raising a pre-seed round to accelerate what beta has validated.
What is your endgame? (Going public, acquisition, growing and staying private, etc.)
Honestly, it's too early to call, and we'd rather be straight about that than perform a plan we can't yet back. Our focus is product-market fit and owning the category we're creating. A company built around this layer, how each person experiences the places around them, could grow into a large independent business, and it would also be a natural fit for a travel or tech player, but we're optimizing for building something people love, not for a quick exit.
