At Byld, we don't just build businessesâwe create game-changing ventures in collaboration with leading corporations. Since 2017, we've been designing, validating, and launching new companies, blending the best of the entrepreneurial and corporate worlds to develop scalable businesses with real impact.
Our venture, Ermine, was born from this vision. Built alongside Erhardt, Ermine is a cutting-edge SaaS platform that centralizes Risk Management, Audit, ESG, and Quality in one placeâautomating evidence collection, ensuring traceability, and increasing operational efficiency.
We are looking for a Founder/CEO with the relentless drive to transform a disruptive tech platform into an international leader. Someone who has taken a B2B digital product from 0 to scale, closed complex enterprise deals, raised capital, and built a world-class team.
You must be the bridge between cutting-edge technology strategy and aggressive business execution.
Start Date: As soon as possible
Contract: Permanent
As CEO & Co-Founder, your mission will be:
Lead capital raising end to end: from crafting the investment narrative and pitch deck to closing rounds (Seed, Series A, or beyond).
Build and cultivate relationships with top-tier investors: VCs, Business Angels, Family Offices, and strategic public grants (R&D).
Design and execute an aggressive growth strategy to dominate the global Audit 4.0 and Risk Management market, nationally and internationally.
Manage P&L, burn rate, and key metrics (MRR, ARR, CAC, LTV, NRR, churn) to maintain consistent growth.
Report to the Board of Directors (Byld + Erhardt) on progress and strategic decisions.
Own the B2B commercial pipeline and close enterprise contractsâlong sales cycles, multi-stakeholder deals.
Build a scalable, repeatable sales engine with clear pricing, upselling, and account expansion playbooks.
Build and lead a high-performance team through an outstanding startup culture.
Collaborate with product and tech to prioritize roadmap based on market feedback and customer discovery.
Proven track record in high-growth B2B SaaS startupsâideally as founder, co-founder, or early C-level executive, having taken a digital product from 0 to scale.
Mastery of SaaS metrics: MRR, ARR, churn, NRR, CAC, LTV.
Hands-on mentality: comfortable wearing multiple hats, from configuring the CRM to closing the first 50 enterprise deals yourself.
Track record closing investment rounds (Seed, Series A, or beyond) and crafting compelling investment narratives and pitch decks.
Established network within the investor ecosystem: VCs, Business Angels, Family Offices
Experience with public funding instruments (R&D&i grants, ENISA, CDTI) is a strong plus.
Expertise in closing complex B2B contractsâlong cycles, multiple decision-makers, high-value deals.
Experience building and leading commercial teams from scratch, with hands-on knowledge of pricing, upselling, cross-selling, and account expansion
Established network of professionals, companies, and decision-makers in the Audit, GRC, ESG, or Quality sector who could be potential clients, partners, or advocates for Ermine.
Deep knowledge of the Audit, GRC (Governance, Risk & Compliance), ESG, or Quality sector and the future of compliance and control.
You aspire to change how Audit 4.0 and control processes are developed in SMEs and roll it out on an international scale.
Familiarity with RegTech, LegalTech, or GovTech ecosystems.
Exceptional communication skills in both Spanish and English (written, verbal, and presentations).
Grit & Resilience: You've faced the "Valley of Death" before and came out stronger. You adapt, learn, and push forward.
Hands-on Execution: Allergic to bureaucracy. Speed > Perfection.
Simplification & Clarity: You distill complexity into a clear direction. No jargon, no fluffâjust focus.
Empathy & Leadership by Example: You inspire, motivate, and invest in the development of your team.
Skin in the Game: An exceptional equity package (up to 15%). This is a co-founder role, not a corporate position.
Competitive salary aligned with startup stage.
Full support from Byld (Spain's first Corporate Venture Builder) and Erhardt as industry-leading corporate partnerâincluding interim management, operational methodology, and Byld's Liquid Building contribution.
Access to Byld's ecosystem: mentors, corporate network, shared resources, and fellow founders.
Experienced, motivated Board of Directors with experience in scaling and corporate venturing.

Byld is a Spanish Corporate Venture Builder founded in 2017 that designs, validates and launches new ventures with corporations sharing risks and rewards from day one. We lead and co-found new ventures from scratch combining the best of the entrepreneurial and corporate worlds to encourage the creation of scalable businesses with an international scope.
We believe that our formula for helping companies innovate is more effective and less risky than traditional methods, as it is entirely devoted to it and linked to the strategy of the corporation in the mid-long term. This allows corporations to properly confront the fierce competence of startups and other rivals and adapt to the constant change of present times, transforming opportunities and tendencies into new disrupting businesses. Ultimately, this is achieved thanks to the combination of the dynamism, versatility and culture behind the startups mindset that we bring to the table and the resources, outreach and experience of the big corporations that we partner with.
