If you want assurance that adds strategic value, choose firms where ESG isn’t a service line – it’s the entire business.
“Large assurance firms often treat sustainability verification like a production line – junior staff running through checklists, ticking boxes and moving on to the next client. Boutique specialists like Speeki treat it as a craft.”
Scott Lane - Lead Auditor and CEO
Six reasons specialist firms deliver stronger assurance outcomes
-

Senior practitioner involvement, not junior staff delegation
In many large assurance firms, sustainability work is delivered by junior associates following standardised checklists, with senior staff involved mainly at proposal stage and sign-off.
Speeki works differently. Senior practitioners lead and remain directly involved throughout the engagement. You are not relying on staff learning on the job, but on experienced professionals who can identify risks that checklist-driven reviews often miss.
-

Strategic insight beyond tick-box compliance
Large firms are built for efficiency and volume: complete the checklist, issue the opinion and move on. This production-line model may achieve technical compliance but rarely delivers strategic insight.
Speeki takes a different approach. We understand your business model and sector risks, benchmark performance, identify gaps and recommend practical improvements – because sustainability is our focus, not just one service line among many.
-

Agility and responsiveness that bureaucracies can’t match
Large firms operate through layers of approvals, standardised methodologies and global quality controls designed for scale. Technical queries can take days to resolve, schedule changes require complex resourcing adjustments and tailored approaches often need multiple internal approvals.
Speeki operates differently. Senior practitioners make decisions directly, adapt methodologies to your circumstances and respond quickly to regulatory change or emerging disclosure requirements – without internal bureaucracy slowing the process.
-

Genuine specialisation, not generalist expansion
Many large audit firms added sustainability to existing audit practices as demand increased, often staffing engagements with auditors trained in ESG. Their core focus remains financial audit, with sustainability delivered as an additional service line.
Speeki was built specifically for sustainability. Our practitioners come from environmental science, corporate responsibility and ESG advisory backgrounds, bringing career-long expertise rather than adapting traditional audit models to a new discipline.
-

Relationship-driven partnership, not client-number focus
In large firms, clients are often allocated based on capacity within a global portfolio. Account managers rotate as staff are promoted or reassigned, and business knowledge is diluted through handovers.
Speeki builds long-term relationships led by the same senior practitioners year after year. We retain context, track progress on prior improvement areas and understand how your stakeholder landscape and materiality priorities evolve – supporting a partnership rather than a transactional service.
-

Economics aligned with quality, not leveraged billing models
Large firms operate leveraged models that rely heavily on junior staff, with limited senior involvement. This rewards efficiency and standardisation, often at the expense of deeper technical analysis and tailored insight.
Speeki’s model is based on senior expertise, not leverage. We price engagements around practitioner involvement and technical complexity, aligning our incentives with investing experience in your engagement rather than minimising it.
We are not quality auditors.
We do not operate laboratories for car tyres.
We do not test medical devices.
We assure business impacts and risk.
When you work with a specialist ESG firm, senior practitioners read your report, understand your sector challenges and provide insight beyond compliance conclusions.
