Spanish professor turns daughter’s 5% sight into a €5 million tech lifeline for the blind
Antonio Sánchez Káiser never asked for a side hustle. He already had tenure, a fluids-lab wind tunnel and papers that few outside academia read. Then Vega arrived—eyes open, retina barely working—and the catedrático discovered that love can pivot harder than any startup.
A phd in stubbornness
Cartagena’s Technical University corridors still echo with the wheeled suitcase he dragged between lectures and the makeshift optics bench where he hacked together a first rig: three micro-cameras, a Raspberry Pi and a tablet that could zoom 30× without pixel death. The goal was brutalist: let his daughter see the blackboard from the back row, full stop. By 2020 the kludge had a name—BemyVega—and a legal entity burning €4.5 million of mixed public grants, regional loans and the kind of private capital that normally chases fintech, not inclusion hardware.
Pilot one was Vega’s own classroom. Pilot two: 100 schools, three universities and Barcelona’s city hall, where councillors realised the same stack could stream council sessions to citizens who are blind, deaf or dyslexic. Revenue crawled at €150 k a year, payroll hit 25 engineers, yet every term-sheet meeting opened with the same slide: a kid with albinism watching a flamenco concert from the 25th row as if seated in the pit. The punchline landed—sign here.
Buy-out that keeps the fire
Corporate Spain likes to absorb, not empower. Grupo Inforges, an IT reseller with 1,200 civil-service contracts, closed the acquisition last November for an undisclosed eight-figure sum. The clause that mattered: Sánchez Káiser stays frontman, R&D reports to him, not to the board. Translation: the catedrático still grades fluid-dynamics exams on Thursday and flies to demo days on Friday. January-February receipts: €600 k, more than the whole of 2022.
The product line now forks twice. One box: 4K pan-tilt cameras, edge AI that tracks professors who refuse to stand still, and a cloud layer that spits out real-time captions, dyslexia-friendly fonts and sign-language avatars. Second box: a SaaS licence that publishers such as Anaya jam inside digital textbooks so a colour-blind teenager can swap chloroplast greens or trigger audio description with two taps. Margins on code beat margins on aluminium.
What still keeps him awake
Vega is 14, top of her class, yet recess remains a battlefield. “She can read the smartboard, but she still can’t spot who’s waving at her,” Sánchez Káiser says inside a lab that smells of solder and sea salt. The next firmware drop will add Bluetooth direction beacons: classmates’ phones ping her tablet with an arrow—left, two metres—so no more neon safety vests on eight-year-olds. The protocol is open-source; he wants Apple and Google to steal it.
Meanwhile, the Spanish ONCE foundation foots the university rollout bill, Cajamar bank funds 50 rural libraries and the city of Valencia just ordered 200 units before the EU accessibility directive hardens in 2026. The queue is no longer charity; it is compliance with teeth.
Sánchez Káiser measures success in micro-moments: a mother texting that her deaf son laughed at a Punch and Judy show because the captioning kept up with the ad-libs; a lecturer realising the same gear streams to a student recovering from eye surgery in hospital. The scale is no longer his daughter; it is every Vega born this morning.
The last wind-tunnel test of the day whirs in the background. He shrugs: “I still publish papers on vortex shedding, but citations won’t hug you at night. A line of code that lets a kid choose where to sit? That does.” The academic in him adds a footnote: purpose, Frankl wrote, is the one thing you cannot be deprived of. Sánchez Káesar weaponised it into a camera array and turned five percent vision into hundred-percent leverage over a market that forgot to look back.
