Our focus
Building trust with your stakeholders
Speeki is an independent audit, assurance and certification firm. We do not design, build or advise on the systems and reports we assess.
Our role is to test them, and to tell you and your stakeholders what we find. That separation is what gives an assurance statement or a certificate its value.
Your customers, partners, suppliers and investors all expect confidence in your approach, your statements and your results, especially in sustainability. Speeki provides that trust.
Scott LaneCEO, founder and lead auditor

We don’t build what we assess. That’s what makes the assurance worth having.
Not sure which solution fits?
Tell us what you need to demonstrate, and to whom, and we’ll point you to the right solution. No obligation. No sales pitch.
