When Convertibles Is the Better Fit
You are a DTC brand on Shopify Plus
The Good's named results skew SaaS and enterprise: Autodesk, The Economist, Xerox. Convertibles' entire practice is $2M+ DTC brands on Shopify Plus, so the playbook arrives pre-tuned to your platform, your checkout, and your traffic mix.
You want execution, not a roadmap
The Good describes its output as validated recommendations and roadmaps backed by research, testing, and implementation support. Convertibles' developers build every variation, ship every winner to 100% of traffic, and handle the surrounding dev and speed work. If your bottleneck is hands on keyboards rather than knowing what to fix, the execution model clears it directly.
You want paid media and CRO in one loop
Convertibles runs Google and YouTube Ads as the second pillar of its program. The Good improves ROAS through onsite experience work, but its public pages do not list paid media management.
When The Good Is the Better Fit
You are a SaaS company
The Good has an entire practice for SaaS: registration, onboarding, free-user monetization, retention, and cancellation mitigation, with named results like Autodesk and Helium 10. Convertibles does not serve SaaS at all.
You want research depth from a credentialed consultancy
HCI degrees on staff, a founder with three best-selling books, 15+ years of practice, and a formalized methodology. If your organization buys on credentials and research rigor, The Good is one of the most credentialed teams in the category.
You are enterprise-scale with internal teams to act on findings
The Good's DXO Program produces validated, prioritized findings your product and engineering teams execute. If you have those teams, a research partner that respects internal ownership fits better than an agency that wants the keys.
Methodology Comparison
The Good spent 15 years doing CRO and concluded the industry's conversion-rate framing was too narrow, so it formalized Digital Experience Optimization in 2024: UX research and behavioral analytics first, testing as validation, the whole digital journey as the unit of work. It is a thoughtful, user-centered methodology with Fortune 500 results behind it.
Convertibles keeps the narrower framing on purpose: revenue-weighted tests on Shopify Plus stores, multi-variation by default (control plus 2 to 4 variations), through Intelligems, every published result at 95% statistical significance, winners shipped by the team that designed them. Less journey philosophy, more shipped revenue per quarter.
Neither is wrong. Enterprises with long funnels benefit from journey-level research. DTC brands with one funnel and paid traffic benefit from testing velocity on that funnel.
Proof and Track Record
Convertibles
36 published case studies, each an individual test with the result, significance level, and revenue impact stated, totaling $2.3M+/month in aggregate measured lift. Public client endorsements from Jones Road Beauty, Performance Golf, and Gymreapers. Proof is test-level and named.
The Good
Named enterprise results: Autodesk +11% subscriptions, Xerox +18.9% product-page revenue, The Economist +5% paid conversions, MasterCraft 33:1 ROI. Headline claims of average 16:1 ROI and hundreds of millions in client revenue created. Founder authored three best-selling books; team featured in Inc., Forbes, and Vogue Business. Proof is enterprise-level and credential-weighted.
The Bigger Picture
The Good deliberately limits who it works with and calls itself a specialized consultancy rather than a do-everything agency. Convertibles made the same choice with a different axis: The Good specialized on a methodology that spans platforms; Convertibles specialized on a platform and bundled everything that buyer needs. Which specialization wins depends on whether your constraint is understanding your users or shipping improvements fast enough.
