Speero (by CXL) review
Peep Laja's research-and-experimentation agency (formerly CXL), a gold-standard CRO methodology focused on long-term growth over short-term wins, with strong multi-year client relationships, but one pointed complaint about not standing behind a paid analytics-setup engagement.

Verdict
Speero (formerly CXL agency, founded 2011 by Peep Laja) is one of the most methodologically respected experimentation agencies, explicitly built to understand customers through data, research, and experimentation for long-term growth, not short-term 'wins,' which is precisely the rigor the 2026 rubric rewards. Clients describe multi-year partnerships and ROI they 'wish they could get everywhere else.' The caveat is a specific service-accountability complaint: a client paid ~$3,250 for an analytics-setup review that a year later still hadn't fixed tracking, and Speero asked them to pay again ($200/hr) to revisit it, concluding they don't stand behind their work. A top-tier experimentation partner; scope analytics deliverables and acceptance criteria tightly.
