Best conversion consultants in New York City

By Expert ShortlistUpdated 10 providersCoverage: New York City
In this guide

New York has plenty of performance-marketing and digital agencies, but far fewer named practitioners who sell broad-funnel conversion consulting from a local base. The strongest choices for NYC buyers therefore include remote specialists in customer research, messaging, UX, analytics, and experimentation. Their location is less important than the quality of the research and the fit with your internal delivery team.

This list covers providers that serve New York City remotely; none is presented as having a verified NYC base or staffed local office.

The consultants

1. Peep Laja

Peep Laja founded CXL, Wynter, and Speero, which handles experimentation, customer research, UX audits, and analytics. The firm is a strong remote match for an NYC company with substantial traffic and the appetite for a sustained testing program.

2. Talia Wolf

Talia Wolf leads GetUplift, using customer research and emotional targeting to improve SaaS and other considered-purchase funnels. She is worth considering when a New York team’s page mechanics look sound but the value proposition is not landing.

3. Joanna Wiebe

Joanna Wiebe founded Copyhackers and offers consulting and workshops around conversion copy. Her work is most relevant when the likely constraint is message-shaped: positioning, pricing language, signup copy, or lifecycle communication.

4. Khalid Saleh

Khalid Saleh co-founded Invesp, a Chicago firm focused on conversion optimization since 2006. The one-hour time difference is simple for NYC teams, and the firm can cover research, testing, and training as an ongoing program.

5. Craig Sullivan

Craig Sullivan’s Optimise Or Die practice combines analytics, UX research, experiment review, and coaching. London is five hours ahead of New York, so he fits teams comfortable with morning meetings and asynchronous analysis.

6. Brian Massey

Brian Massey founded Conversion Sciences, an Austin firm offering audits, managed optimization, landing-page work, and training. It is a practical choice for NYC ecommerce and lead-generation teams that want delivery as well as strategic diagnosis.

7. Tim Ash

Tim Ash wrote Landing Page Optimization and now provides consulting, executive advisory, and training. He fits leadership teams that need to connect page changes with a larger digital-growth agenda, though he works from San Diego rather than New York.

8. Karl Gilis

Karl Gilis co-founded AGConsult, a Belgium-based usability and conversion practice centered on user research and testing. His approach is appealing when watching real users is more useful than pushing a high monthly volume of experiments.

9. Sean Ellis

Sean Ellis offers growth workshops, courses, and one-to-one sessions. He is a better fit when conversion is tied to activation, positioning, or the overall growth model than when a company simply wants an outsourced testing team.

10. Hiten Shah

Hiten Shah co-founded Crazy Egg and KISSmetrics and now publishes founder research and advises companies. His current focus makes him useful for high-level pattern recognition, not for operating a weekly test pipeline from New York.

Buyer guide

For New York teams, remote delivery works well when the provider can get clean access to analytics, customers, and the people who ship the site. Decide first whether the engagement ends with diagnosis or includes copy, design, development, and analysis.

Time zones create real operating differences. Chicago and Austin providers overlap almost completely with New York; California providers start later; UK and European specialists compress the shared day into the morning. Put required meeting windows and response times in the proposal.

Ask to see a complete experiment story, including a test that lost. The answer should cover the original observation, the hypothesis, sample size, duration, result, and the next decision.

Landing-page CRO agencies in New York City fit paid-acquisition pages that need design and production. Checkout optimization consultants in New York City focus on cart and payment completion. A growth product consultant is a better fit when retention or activation is the larger issue.

FAQs

Are any of these consultants based in New York City?

None is presented here as locally based. Every location line states where the provider works from when that information is public.

Does remote CRO work well for NYC companies?

Yes. Most research, analytics, copy, design review, and experiment planning can happen remotely. The important checks are data access, meeting overlap, and who owns implementation.

Which time zones are easiest from New York?

Central time is only one hour behind and usually causes no trouble. Pacific time shifts live work later; UK and European providers require morning-heavy collaboration.

What should come before an A/B test?

The hypothesis should come from observed behavior, customer research, or a measurable funnel problem. Testing random design preferences wastes traffic and rarely builds useful knowledge.
