Leader to Know: Isidoro Martínez Soñora
Co-Founder & CEO @ Tecalis
August 19, 2026
What's the backstory? How did you end up doing this?
While studying Telecommunications Engineering, I became fascinated by how paper-heavy and inefficient critical business agreements were. My co-founders and I saw an immense opportunity to modernize digital trust, electronic signatures, and regulatory compliance. We launched Tecalis to make identity verification seamless, secure, and globally accessible.
What was your first entrepreneurial moment?
My first moment was during university when I created a custom software tool that solved a pressing operational challenge for a client. Seeing technology I built create immediate, tangible value for someone else was a major turning point. It made me realize I wanted to build scalable software products for a living.
How do you define success today?
Today, success means creating technology that becomes essential infrastructure—powering millions of secure digital transactions without friction. Internally, it means building a high-performing culture where our team can innovate freely and scale sustainably. It is all about long-term value creation over short-term hype.
What's something you've built or fixed that you're still quietly proud of?
I am quietly proud of leading Tecalis’ transition from custom solution engineering to a unified, product-driven platform using both hardware and software. Re-architecting our identity engine to handle complex regulatory compliance in real time was a huge technical challenge, but it fundamentally elevated our trajectory as a SaaS company.
What are the most energizing moments in your work?
The most energizing moments come when complex technology transforms into an effortless client experience. Launching a platform update that instantly solves a massive compliance challenge for enterprise customers, or closing a key strategic partnership, gives me an unmatched surge of momentum.
Describe your typical day
My days balance strategic focus with high-level execution. I reserve mornings for deep work, key decision-making, and alignment with our product and leadership teams. Afternoons are usually dedicated to market strategy, strategic client conversations, and reviewing operational metrics.
Any personal rituals or habits you credit for your success?
I rely on strict time-blocking and starting my day with physical activity before opening any communication channels. Protecting dedicated slots each week for deep, distraction-free strategic thinking has been vital for making clear decisions under pressure.
Remote, hybrid, or in-office: what works for your team, and why?
A full-remote model works best for us because it delivers the ideal balance. Remote flexibility provides the deep-focus environment required for complex engineering, while targeted meeting time fuels cross-team alignment, creative problem-solving, and company culture.
What do you do when you're not working?
When I am offline, I make a point to disconnect completely by spending time outdoors. Staying active, practicing sports, and spending uninterrupted quality time with family and friends helps me reset and maintain sharp perspective.
What keeps you interested in this industry?
Digital identity and sales flows evolve rapidly alongside changing regulations and emerging AI capabilities. Establishing secure digital trust in a fast-moving market is an ever-changing challenge, meaning there is zero room for complacency and always a fresh problem to solve.
What principles guide how you build?
We build with a "user-experience and compliance first" mentality without ever sacrificing simplicity. Every feature must solve a real business friction point while adhering to strict regulatory frameworks. If an implementation isn't scalable, secure, and completely frictionless for the end user, back to the drawing board we go.
What's your approach to hiring and building a team?
We look for high ownership, adaptability, and genuine curiosity over just impressive resumes. In a fast-moving space, we need problem solvers who take pride in crafting quality software and thrive in a collaborative environment. Building a strong team means empowering people with autonomy while aligning them around a clear, shared vision.
What kinds of customers or deals do you say no to?
We walk away from opportunities that compromise on high compliance, security, or data privacy standards. Maintaining platform scalability and long-term product integrity always takes priority over quick revenue.
How do you balance growth with sustainability?
We prioritize strong unit economics, enterprise retention, and operational efficiency over growth-at-all-costs. By continuously refining our core platform and retaining strict capital discipline, every growth phase is grounded in real customer value. For us, sustainable expansion comes from building software that customers cannot live without.
What's your pricing philosophy?
Our pricing philosophy is strictly value-aligned and transparent. We charge based on transaction volume and platform utility, ensuring clients pay proportionately to the scale and ROI they derive from our identity solutions. This approach allows companies to start lean and scale seamlessly as their usage expands.
What software does your own team run on?
Our infrastructure runs on GCP, with GitHub and Jira managing our product engineering workflows. For internal collaboration and go-to-market execution, we rely heavily on Google Suite, Cursor and HubSpot to keep our team fully aligned.
What do buyers most often misunderstand about what you do?
Buyers often assume eSignatures and identity verification are simple, commodity UI features. In reality, the hard part is what happens under the hood—ensuring strict regulatory compliance, conversion rates suveillance, cryptographic fraud prevention, and seamless audit trails. It is fundamentally an infrastructure and sales-enablement engine, not just a digital signature box.
What trends in your space do you think are overhyped?
Fully autonomous "AI-only" verification models without robust human-in-the-loop fallbacks are overhyped right now. While AI accelerates document checks, enterprise compliance requires absolute legal certainty and accountability. Relying blindly on unproven AI models creates massive regulatory exposure that many companies aren't prepared for.
What's something you believe about your industry that most people would disagree with?
Most people view strict regulatory compliance as a painful bottleneck that slows down software development. I believe compliance is actually the ultimate competitive moat and growth enabler. Companies that embrace regulatory complexity as a core feature rather than a chore build far more durable, high-barrier enterprise platforms.
What's a decision you got wrong, and what did it cost you?
Early on, we mistakenly tried to force a rigid, one-size-fits-all SaaS model and resisted customizing our platform for enterprise clients. This cost us major early deals, as we failed to recognize that large corporations have highly complex and unique integration needs. We quickly learned that our ability to deliver tailored, deeply integrated solutions is actually our greatest competitive advantage, not a weakness.
What do you think your category looks like in five years?
In five years, customer onboarding will be largely backgrounded through interoperable digital identity wallets. The category will shift from active document scanning to instant, sovereign digital credential exchange. Vendors will compete not on document accuracy, but on how seamlessly they orchestrate real-time, cross-border trust networks.
What advice would you give someone starting a software company today?
Validate deep customer pain before chasing hyper-growth, and focus relentlessly on unit economics from day one. Hype fades quickly, but building a product that solves an undeniable, revenue-critical problem creates lasting enterprise value. Stay disciplined, master your core niche, and build for sustainable retention over vanity metrics.
When a regulated enterprise stalls a deal, what's the real objection underneath the compliance language they give you?
Underneath the "compliance concerns," the real objection is almost always fear of operational disruption and internal liability. Regulated enterprises hesitate because changing an onboarding flow impacts legacy IT systems, cross-departmental workflows, and human risk exposure. We overcome this by showing them that our solution integrates modularly without forcing a high-risk overhaul of their existing architecture.
Where does identity verification end and fraud prevention begin, and why does that boundary keep moving?
Identity verification answers who someone is, while fraud prevention evaluates how they are behaving and whether they should be trusted in that moment. That boundary keeps moving because synthetic identities and generative AI deepfakes now allow fraudsters to pass traditional document checks seamlessly. As a result, ID verification must constantly incorporate continuous risk scoring and behavioral analytics to stay effective.
What does a failed onboarding journey cost a business that most finance teams never actually calculate?
Finance teams easily measure compliance fines, but they consistently overlook the fully burnt Customer Acquisition Cost (CAC) spent on users who abandon the journey mid-way. A failed onboarding process destroys high-intent pipeline and permanently forfeits future Customer Lifetime Value (LTV). Additionally, it inflates back-office expenses through costly, manual remediation attempts that rarely recover the lost user.
How do you handle the moment a prospect's legal team and their sales team want completely opposite things from your product?
We frame our platform as an adaptive bridge rather than a compromise. By leveraging risk-based dynamic onboarding, we keep the journey virtually frictionless for low-risk customers while automatically triggering strict step-up checks only when risk signals fire. This allows GTM teams to maximize conversion velocity while keeping Legal completely protected.
What do outsiders consistently get wrong about what friction in an onboarding flow actually signals?
Outsiders assume all friction is inherently negative and damages conversion. In reality, users expect a reasonable level of friction when dealing with high-value or regulated financial services because it signals security and builds trust. The problem isn't friction itself, but blind, uniform friction that treats a trustworthy customer the exact same way as a high-risk transaction.
As eIDAS 2.0 reshapes digital identity across Europe, which assumption baked into most onboarding stacks today will break first?
The assumption that onboarding must always begin with physical document capture and OCR scanning will break first. eIDAS 2.0 and European Digital Identity Wallets move the market from manual document extraction to instant, cryptographic credential verification. Stacks built solely around document photo processing will quickly become obsolete bottlenecks.
