Herkul
What does Herkul do and what is our working model?
Herkul is a software engineering studio based in São Paulo, Brazil. We develop custom enterprise applications, high-performance web platforms using Next.js, and prepare enterprise systems for the new era of AI search (AEO and GEO).
Most of the tech market falls into two extremes: agencies delivering fragile, disposable templates, or bloated consultancies that charge for endless layers of account managers while outsourcing execution.
We founded Herkul to build the exact opposite: a lean engineering studio where the people architecting the solution are the ones writing and verifying the code. We take on a limited number of projects at any time, ensuring deep attention, technical clarity, and direct communication.
We don't believe in generic off-the-shelf fixes for unique problems. Every system is built to last, using the right stack for your business context, without locking you into proprietary platforms or predatory contracts.
Engineering Principles
How we think about and build technology
Truly Custom Architecture
No pre-bought themes disguised as custom software. We design architectures from scratch around your actual business model, ensuring clean data structures and long-term maintainability.
Performance Is Non-Negotiable
Reactive interfaces, optimized Core Web Vitals, and low-latency APIs. Fast software isn't cosmetic: it directly drives retention, conversion, and operational reliability.
AI-Ready (AEO & GEO)
The web is now parsed and summarized by generative AI engines. We structure data, semantic schemas, and integrations so your business is easily cited by tools like ChatGPT, Perplexity, and Gemini.
Complete Autonomy & Zero Lock-in
You retain 100% ownership of your code, cloud infrastructure, and documentation from day one. No black boxes, no artificial dependencies.
Our Team
The engineers behind the code
At Herkul, technical leadership is hands-on. There are no intermediaries between the initial architectural discussions and the final deployment: our projects are led by engineers with proven experience in scalable systems.
Leading engineering at Herkul, Gabriel brings over 6 years of experience building and supporting mission-critical software for major enterprises and global telecom operators.
With a proven track record architecting high-scale platforms serving over 30,000 active users with strict demands on performance and stability, he drives the technical standards and reliability of every solution delivered by Herkul.
Operating Model
Lean Core & Specialized Network
We operate with a focused technical core. When a project requires specialized competencies—such as advanced product design, penetration testing, or complex data engineering—we bring in trusted senior partners under the same high standards of technical rigor and transparency.
