We don’t just build AI—we build it with humanity in mind.
At Sigma, our values aren’t an internal document. They’re a daily practice.
We believe AI should serve people—and the way we collect, annotate, and evaluate data reflects that principle at every level. From team culture to client collaboration, from annotator inclusion to model outcomes, our human-first values guide how we work and who we are.
We’re proud to deliver high-quality, high-context data. But we’re even prouder of how we do it: with integrity, empathy, and respect.
The values that shape Sigma
Justice & fairness
We seek the common good while respecting the dignity of every individual. We promote fair treatment, equal opportunity, and accountability. We speak up in the face of injustice—within our team, across projects, or in the datasets we handle.
Empathy & expression
We understand the importance of stepping into another’s perspective—whether we’re annotating intent, mentoring a teammate, or listening to a client. We champion freedom of expression and respect for diverse identities, opinions, and lived experiences.
Pursuit of excellence
We hold ourselves to a high standard of quality, curiosity, and improvement. From the smallest label to the most complex model evaluation task, we commit to doing our best—and making it better tomorrow.
Adaptability
AI changes fast. So do we. We embrace learning, flexibility, and experimentation, staying ahead of evolving client needs and model demands. We view every challenge as an opportunity to grow.
Consistency & diligence
We do what we say. We deliver on time, with care, and with the highest attention to detail. Our commitment to reliability makes us a trusted partner in some of the world’s most sensitive, high-stakes AI projects.
Transparency in communication
We prioritize openness and clarity in our communication—internally, with clients, and across our annotation teams. Transparency builds trust, strengthens feedback loops, and ensures better results.
Passion & teamwork with balance
We love our work—and the people we work with. We foster an environment of collaboration, inclusion, and mutual respect. And we recognize that real success includes space for well-being, family, and personal growth.
Putting values into action
These aren’t just words. Our values shape how we:
- Hire and support a workforce that spans 100+ countries
- Train annotators to uphold fairness, accuracy, and empathy
- Build ethical annotation guidelines and inclusive datasets
- Help clients create AI systems that reflect—not distort—human values
Our clients empower us to deliver on this mission. And together, we’re building AI that’s not only intelligent—but intentional.
