Zach Wendkos, founder of Wavelength

Who you're working with

I'm Zach. I spent nearly two decades growing a St. Pete startup into a global online business.

I joined a local company in its early days and helped build it from startup through a successful exit, growing it into a business that serves more than 3 million customers worldwide. The whole job came down to three things: understanding who our customers were, reaching more people like them, and turning that attention into revenue, millions of times over.

Now I bring that same playbook to a small number of businesses and brands here at home. Not an agency with 40 clients and a rotating cast of account managers. One operator, a handful of clients, done properly.

Three problems, usually in this order.

Most marketing budgets skip the first one. They buy more traffic before anyone knows who the best customers are or why they buy, then wonder why the website doesn't convert. Start with the customer and everything after it gets cheaper and sharper.

1

Know your customers

Who buys, why they choose you, what they'd pay more for, and who you should stop chasing.

  • Customer surveys
  • Advanced analysis of your sales and CRM data
  • Interviews and voice of customer
  • Clear, ranked recommendations

2

Find more customers

Show up where the right people are already looking, and pay less to reach them.

  • Paid media on Google and Meta
  • SEO and Google Business Profile
  • Visibility in AI search
  • Email and lifecycle marketing

3

Convert more customers

Turn the attention you're already earning into calls, bookings, and sales.

  • Website builds and conversion fixes
  • Landing pages and testing
  • AI agents that answer and follow up
  • Automations that give your team hours back

Sound familiar?

You're guessing who your best customer is

Everyone has a hunch. Few businesses have checked it against their own numbers, and the hunch is wrong more often than you'd think.

Ads that get clicks, not customers

The dashboard says traffic is up. The bank account disagrees. Usually the targeting is aimed at who you assume buys instead of who actually does.

A website that never rings the phone

It looked great when it launched. But visitors can't find what they need in ten seconds on their phone, so they hit the back button and call someone else.

Invisible to AI, too

Your customers are starting to ask ChatGPT and Claude who to call, and those tools have never heard of you. The businesses they recommend are the ones that did the visibility work.

How we'd start

No packages to decode and no price sheet to guess from. Every engagement is scoped to what your business actually needs.

1

Request a free first look

Answer a few quick questions, including your website. I'll look at your business before I reply, so our first conversation starts with something useful instead of a sales script.

2

A 20-minute call

We talk about your customers, your goals, and what's been tried. If I'm not the right fit, I'll say so on the call and point you somewhere better.

3

A scoped plan, in writing

What I'd do, in what order, what it costs, and how we'll know it worked. Fixed scope and a fixed price, agreed before anything starts.

Three ways to work together

Pricing is scoped to the work and agreed in writing after our first call. No 12-month contracts, no setup fees, no surprise invoices.

A project

Defined start and finish

A customer study, a website rebuild, an AI agent. One clear deliverable, one fixed price.

Ongoing

Month to month

I run the work that compounds: paid media, search, email, conversion testing. A plain-English report and one strategy call a month.

Fractional CMO

Limited to two clients

A senior operator running your marketing across all three areas, without the full-time payroll.

Case studies from local clients are coming as engagements wrap. Until then, judge me on the first reply: you'll know quickly whether I see things others missed.

1 of 3

Know your customers.

Most businesses have more customer data than they realize and less understanding than they think. I turn surveys, sales data, and customer conversations into a clear picture of who buys, why, and what would make them buy more.

Get a free first look

Questions this answers

  • Who are our most valuable customers, and where do they come from?
  • Why do people choose us over competitors, and why do they leave?
  • What would customers happily pay more for, and what are they tolerating?
  • Which customers cost more than they're worth, and should we stop chasing them?
  • What words do customers use to describe their problem, so our marketing can use them too?

What I do

Customer surveys

Designed properly: the right questions in the right order, sent to the right sample, with an incentive that gets responses without skewing the answers. I'll use whatever survey tool you already have, or set one up.

Advanced analysis

Segmentation, customer lifetime value, cohort retention, and what actually drives purchase and repeat purchase, run against your real sales, CRM, and survey data. The math stays in the appendix; the findings come in plain English.

Interviews and voice of customer

Conversations with recent buyers, lost deals, and customers who left, plus a close read of your reviews, support emails, and sales calls. This is where the words for your next ad usually come from.

Recommendations

The point of all of it. What to change in your offer, pricing, messaging, and targeting, ranked by impact and effort, so you know what to do Monday morning.

What you walk away with

A customer profile anyone can use

A clear description of your best customers that you can hand to whoever writes your ads, builds your website, or trains your sales team.

Segments with dollars attached

Not just "who" but "worth how much." Which groups are growing, which are shrinking, and where the next dollar of marketing should go.

Your customers' own words

The language they use for the problem you solve, organized and ready to drop into headlines, emails, and sales conversations.

A ranked action plan

Prioritized recommendations with the reasoning behind each, plus a walkthrough so nothing needs decoding.

Fair questions

Do we need a lot of data for this to work?

No. Larger businesses usually have plenty sitting unused in their CRM, ecommerce platform, or email tool. Smaller ones often get more from a well-designed survey and a handful of interviews than from any dashboard.

Will you talk to our customers directly?

If you want me to, yes, and customers are often more candid with a neutral third party. Every outreach goes out in your name, with your approval, and nothing is sent to your list without your sign-off.

What happens to our data?

It stays in your accounts wherever possible. What I can access, and for how long, is spelled out in writing before anything is shared. I never use one client's data for another.

We already know our customers. Why pay for this?

Maybe you do, and then the research confirms it cheaply and you spend with more confidence. In my experience, most businesses are right about who buys and wrong about why, and the why is what makes marketing work.

Find more customers like your best ones.

2 of 3

Get found on Google, by the right people.

Paid media, search, AI visibility, and email: the channels that put your business in front of people already looking for what you sell, aimed at the customers you actually want.

Get a free first look

What I do

Paid media

Google and Meta campaigns built around the customers worth acquiring, not the cheapest clicks. You fund the ad spend; I make sure it isn't wasted, and I'll tell you plainly when a channel isn't paying for itself.

Search and Google Business Profile

Showing up in the map results and on page one for the services you make money on. Categories, reviews, pages built to win specific searches, and the local links that actually move rankings.

AI search visibility

More of your customers now ask ChatGPT, Claude, and Google's AI answers who to call. The businesses those tools recommend are the ones with clear, consistent, well-cited information online. I make sure that's you.

Email and lifecycle

The cheapest customer is the one you already have. Welcome series, win-back campaigns, and the follow-ups that turn a first purchase into a habit.

Reviews and reputation

A review system your team can run in five minutes a job, because review count and recency decide more local rankings than almost anything else.

Partnerships and referrals

The businesses that already serve your customers before or after you do. A few well-chosen partners can outperform an ad budget.

Better when step one is done

When targeting comes from real customer research instead of a guess, ads get cheaper, content gets sharper, and the people who arrive are the ones who buy. If we haven't done that work yet, I'll tell you how much of it you need before we spend a dollar on media.

Social media management

Posting isn't marketing. If your customers search for what you sell, we'll win them where they search.

Guaranteed rankings

Anyone who guarantees a #1 spot on Google is lying to you. I guarantee the work, the reporting, and the honesty about what's working.

Miracles by Friday

Search compounds over months. If you need calls this week, that's a paid media conversation, and I'll tell you whether it's worth having.

Fair questions

How fast will we see results?

Paid media can move numbers within weeks. Search and AI visibility compound over months. Most plans use the first to fund patience for the second.

Do you manage the ad spend itself?

The ad spend stays in your accounts and on your card. I build, run, and report on the campaigns. You can see every dollar, all the time.

What does reporting look like?

One page, plain English, tied to revenue: what happened, what it means, what's next. The charts live in an appendix for whenever you want them.

Who does the actual work?

I do. For specialized execution I bring in specialists I've vetted, under my direction and review. Nothing ships without me looking at it.

Next

Convert more of the people you find.

3 of 3

Convert more of the customers you already reach.

Websites that turn visitors into calls, and AI agents and automations that answer, follow up, and handle the busywork, so fewer good leads slip through the cracks.

Get a free first look

Websites that do their job

A website has one job: turn a visitor into a customer. Most are built to look good in a portfolio instead.

Website builds and rebuilds

Fast, clear, mobile-first sites where the phone number, quote form, or booking path is impossible to miss. Built on a platform your team can actually update.

Conversion fixes

Often you don't need a new site, just the right ten changes to the one you have. I find the leaks in the first ten seconds of a visit and close them.

Landing pages and testing

Dedicated pages for your ads and offers, with real A/B tests so decisions come from results instead of opinions in a meeting.

Lead capture and follow-up

Forms that people finish, and a follow-up sequence that goes out in minutes, not days, while the prospect is still interested.

AI agents and automations. Systems, not chatbots.

Most businesses have tried ChatGPT, gotten a generic answer, and gone back to doing everything by hand. The problem isn't the AI. It's that nobody set it up with context about your business, connections to your tools, and a reliable process. That setup is the work.

Lead response agent

Answers new inquiries within minutes, asks the qualifying questions your best salesperson would, and books the call, day or night.

Email response drafter

Drafts replies to routine messages in your team's own words, so a person reviews and sends instead of writing from scratch.

Proposal generator

Turns a call transcript or a few bullet points into a polished, on-brand proposal, while the prospect is still warm.

Client reporting engine

Pulls your real numbers and writes the monthly recap in your voice. Three hours becomes three minutes.

Meeting prep

Before every important call, a one-page brief on who you're meeting, what's changed, and what to bring up.

Research briefings

A scheduled brief on your competitors, market, or prospects, in your inbox before you think to ask.

Those are the common ones. The first conversation usually surfaces two or three more, because every business has its own version of the Friday afternoon report.

I don't just sell this. I run it.

These aren't systems I learned from a YouTube course. I build and run them every week at day-job scale, inside a business serving more than 3 million customers: automated reporting, scheduled research, and content pipelines connected directly to live ad platforms and data. Wavelength brings the same builds to businesses here at home, sized for a local team.

1

Map the work

A working session on the task your team complains about most. I'll tell you honestly whether it's worth automating and what the payback looks like in hours.

2

Build and test

Every agent and automation gets tested against your real work, repeatedly, until it's reliable. Most builds take about two weeks.

3

You take the keys

Plain-English documentation, a training session for your team, and support after launch. It runs in your accounts, on your data, whether or not we keep working together.

Fair questions

Do we need to be technical to use this?

No. If your team can use email, they can run these systems. I handle setup, the documentation is plain English, and the training session means nobody is left guessing.

Will an AI agent embarrass us in front of customers?

Not if it's built properly. Agents get clear limits on what they can say, a handoff to a real person for anything outside those limits, and testing against real conversations before they go live.

Will this replace people on my team?

In my experience it replaces the part of their week they hate, not the people. If someone tells you AI will run your whole business unattended, hold onto your wallet.

What happens when it breaks or the AI changes?

Software and AI models change, and automations need occasional care. Every build includes a support window, and ongoing care is available if you want it. Either way you have documentation, so you're never stranded.

Should we fix the website before adding AI?

Usually, yes. An agent can't rescue a page nobody can navigate. I'll tell you which comes first for your business.

About

The playbook that built one of St. Pete's biggest online businesses. Pointed at yours.

Zach Wendkos, founder of Wavelength, in St. Petersburg

I'm Zach, and I've spent nearly twenty years turning attention into paying customers.

I grew up in Florida, spent the early part of my career in New York, and came back to St. Petersburg to join a local startup in its earliest days. Over nearly two decades I helped grow it into one of the largest online education businesses of its kind in the world, from first customers through a successful exit. Today I run revenue for that same business, which serves more than 3 million customers around the globe.

That growth didn't come from magic or a big-agency retainer. It came from three disciplines, practiced relentlessly: studying customers until we understood them better than competitors did, reaching more people like them, and building a website and follow-up that turned their interest into revenue.

Along the way I noticed something that bothered me. The businesses that make this region run (the contractors, the marine businesses, the practices, the firms, the local brands) mostly can't get that kind of help. They choose between a national agency that treats them like account #4,317 and a freelancer learning on their dime.

Wavelength is my answer. A deliberately small practice, a handful of clients at a time, with the same playbook I run at day-job scale, including the AI systems I build and use every week.

What working with me is actually like

Small on purpose

I cap the client roster so every business gets senior attention. When you have a strategy question, you're asking the person who built the strategy, because there's nobody else here.

Structured on purpose

Fixed scope, a monthly report in plain English, one strategy call a month. You won't hear from me daily, and that's the point: you're paying for outcomes, not activity.

Honest on purpose

If something isn't working, the report says so. If you don't need a service, I won't sell it to you. And if your biggest problem isn't marketing, I'll tell you that too.

Why "Wavelength"

The name is a promise. Three of them, actually.

A frequency

Your customers are out there right now, searching, scrolling, and asking AI tools who to trust. My job is tuning your business to the frequency they're on, so you come through clearly while competitors sound like static.

A way of working

"On the same wavelength" is the whole point of hiring one senior operator instead of an agency. You talk directly to the person doing the work, and nothing gets lost in between.

A home

Waves belong to St. Pete. I work with businesses here on the Gulf Coast, because knowing this market, its seasons, its storms, and its people is part of what you're paying for.

That line under the logo is a flatline breaking into a wave. It's what I do: your business, before and after.

I like scoreboards.

Earlier in my career I worked for the Tampa Bay Rays and IMG, and before that I captained the baseball team at Princeton. I mention this less as a credential and more as an explanation: marketing without a scoreboard is just noise, and everything I do for clients comes with a score attached.

When I'm not working you'll find me on a golf course making optimistic club selections, or somewhere around St. Pete with my dog.

Privacy policy

Plain English, like everything else here.

Effective September 23, 2026

This policy explains what information Wavelength ("I," because this is a one-person practice) collects when you use wavelengthstpete.com, and what happens to it. The short version: I collect the minimum needed to run the site and respond to you, I don't sell any of it, and you can ask me to delete it at any time.

What I collect

The contact form. The form on this site is hosted by Typeform. When you fill it out, I receive what you enter there, such as your email address, your website, and what you're looking for help with, so I can reply personally. If you opt in to occasional emails, I use your address only for those, and every one includes a way to unsubscribe.

Emails and calls. If you email me or book a call, I receive what you provide: typically your name, email address, business name, and whatever you write. Call bookings are handled by Calendly, which asks for your name and email to confirm the appointment.

Information collected automatically. Like most websites, this site uses Google Analytics to understand how visitors use it: pages visited, approximate location at the city level, device and browser type, and how you arrived. This data is aggregated and doesn't identify you personally. Analytics relies on cookies; you can block them in your browser settings and the site will work fine.

Client information. If we work together, I'll access business accounts and customer data you grant me (such as your CRM, survey results, ad accounts, or website platform) solely to perform the agreed work, under the terms of our services agreement.

How I use it

  • To reply when you contact me, and to schedule and hold calls you book
  • To deliver services if you become a client
  • To understand, in aggregate, how the site is used so I can improve it
  • To send occasional emails, if and only if you asked for them. Every email includes a way to unsubscribe, and if you ask me to remove you, I will, immediately.

What I never do

  • Sell, rent, or trade your information to anyone
  • Use one client's data for another client's work
  • Share client data or account access with third parties beyond the tools needed to do the work
  • Send marketing on behalf of anyone else

Third-party services

The site relies on a small set of tools, each with its own privacy policy: Calendly (scheduling), Google Analytics (site usage), Typeform (the contact form), Google Workspace (email), and a payment processor (Stripe) if you purchase services. I share with these providers only what's necessary for them to do their jobs.

How long I keep it

Form submissions, emails, and booking records are kept as long as they're useful for our relationship or as required for business records (such as invoices, which tax law requires me to retain). Analytics data is retained per Google Analytics' standard settings. If we don't end up working together, I don't keep client account access; any access you granted should be revoked afterward, and I'll remind you to do it.

Your choices

You can ask me at any time what information I have about you, ask me to correct it, or ask me to delete it, and I will, except where the law requires me to keep it (like tax records). Email zach@wavelengthstpete.com and I'll handle it personally, usually within a few days.

Children

This site is for business owners and isn't directed at anyone under 18. I don't knowingly collect information from children.

Changes to this policy

If this policy changes in any meaningful way, the effective date above will change with it. Material changes to how client data is handled will be communicated to active clients directly.
