Coast to Coast Pools: 29% More Web Leads and a 22% Conversion Lift, Before and After Eva

Coast to Coast Pools, #4 on Pool & Spa News' 2026 Top 50 Builders, put Eva by Symbiont on its website in June 2026. Comparing the three months before launch with the three full months after, its website conversion rate rose 22% and its web leads rose 29%, on traffic that grew less than 6%.

Eva is the AI assistant Symbiont builds for pool builders' websites: she answers visitors' questions, renders the pool they design into their own backyard, and captures the consultation request. This case study is the full before-and-after of one pool deployment, final as of September 30, 2026. At the builder's request we publish percentage changes only, never its lead or visitor counts.

Who is Coast to Coast Pools, and what was the problem?

Coast to Coast Pools is a Florida builder ranked #4 on Pool & Spa News' 2026 Top 50, and its problem is the one every builder shares right now: the market shrank underneath everyone's traffic. Pool Corporation, the largest distributor in the industry, estimates in its annual report that just below 60,000 new in-ground pools were built in the U.S. in 2025, a number its CEO called about half of the pandemic peak.

When the pool of buyers shrinks, a builder's website traffic tends to shrink with it, and no amount of marketing spend fully controls that. What a builder does control is what happens to the visitors who still come. Coast to Coast's own traffic held roughly flat across the comparison; what changed was how many of those visitors became leads.

What went live, and when?

Eva's chat, with satellite-view pool rendering, on June 17, 2026. A visitor could ask questions, design a pool, and see it rendered onto the satellite image of their own backyard in under 60 seconds, with the design delivered on their own landing page and the consultation request captured with the full conversation attached.

In August the site added a Design My Pool entry in the header and on-page engagement hooks that lead visitors into the design flow, so the render stopped being something a visitor discovered inside the chat and became something the site actively offers. Eva's own visitor-to-lead rate rose about 30% from July to August, the month those entry points shipped, while the site's combined rate held steady; the combined step came in September. Symbiont is an AI chatbot and visual conversion system. Chat is the front door, not the whole product, and the entry points are the rest of the product put in front of people.

What did the before-and-after comparison show?

More leads from nearly the same traffic. The comparison sets March through May 2026, before Eva, against July through September 2026, after it, and leaves out June because Eva went live mid-month.

Month by month, the conversion rate moved with the product. Every month after launch converted better than every month before it, and September's rate was the highest of the six, on the lowest traffic of the six.

Were Eva's leads new, or shifted from the website's forms?

Both, and the net is what counts: counting forms and Eva together, the website turned 22% more of its visitors into leads than it did before launch. Within that, the site's form-only conversion rate fell about 26% while Eva's leads made up 40% of everything the website produced. Some of those Eva leads are visitors who would have filled in a form anyway and found a better way to reach the builder, and some of the form decline is likely seasonal. We cannot separate the two with this data, which is why it is the most important caveat here. That combined number, not Eva's lead count, is the one a builder should judge any conversion tool by, ours included. It is the same test our guide to auditing vendor numbers asks every dealer to apply.

How are the Coast to Coast numbers measured, and what are the caveats?

Traffic and form leads come from the builder's own website analytics, Hibu, the dashboard the builder logs into. Eva's leads come from Symbiont's analytics for the site, with test leads removed. Web leads are website forms plus Eva; phone calls are excluded. September data runs through September 29.

The caveats, plainly. This is one builder, three months against three months, and the two periods sit in different parts of the year, so seasonality can move traffic and conversion in ways we cannot fully separate from the launch. Treat the direction as the finding and the exact figures as one company's.

Why does the render carry the conversion?

Because it gives a quiet browser a reason to identify themselves that a contact form cannot offer. On this builder's site about 1 in 4 rendered pools becomes a lead: a homeowner who has tapped through shapes and styles, seen the result on their actual yard, and left their details to get the design is a different unit of work than a form fill. The psychology of seeing it first is its own post, and where in-backyard rendering sits among everything else a builder can fix is the job of our website conversion guide.

Before: the yard, from the satellite image of the address.After: their pool, rendered in their own yard in under 60 seconds.

None of this was custom-built for one company. The chat, the render studio, and the on-page entry points are the standard toolkit Eva runs for pool builders.

What can other pool builders take from this?

Three things transfer. First, when the market shrinks your traffic, conversion is the lever you still own. The arithmetic of getting more leads without more traffic is this case study in general form. Second, give the visitor something to do besides a form: a pool rendered on their own backyard converts browsers a quote button never touches. Third, entry points matter as much as the tool. The jump in Eva's own rate in August did not come from new AI; it came from making Design My Pool impossible to miss.

The same mechanism, in a different vertical, is documented in our Coast Buick GMC case study: there the reason to identify yourself is a deal the shopper builds, here it is a pool the homeowner designs. High-ticket buyers research the same way everywhere.

FAQ: what pool builders ask about this case study

How much did Coast to Coast Pools' website conversion change?

It rose 22%, comparing March through May 2026 with July through September and counting website forms and Eva together. Web leads rose 29% on traffic up about 6%, and every month after launch converted better than every month before it, with September the highest of the six.

What did Coast to Coast Pools actually deploy?

At launch in June, Eva's chat with satellite-view pool rendering: design in the conversation, rendered on the buyer's own backyard, delivered on their own landing page. In August, a Design My Pool entry in the site header plus on-page hooks that lead visitors into the design flow. It is the standard Symbiont pool toolkit, not a custom build.

Did the website's forms get fewer leads after Eva went live?

Yes. The form-only conversion rate fell about 26%, and Eva produced 40% of web leads after launch. Some of those visitors would likely have used the form, and some of the decline may be seasonal. Counting both channels together, the site still converted 22% more of its visitors than before.

How fast could another builder expect signal?

Setup takes about 48 hours, and one full month of traffic is enough to read a first rate against the months before. At Coast to Coast, the first full month after launch already converted better than every month before it, and by September the rate was the highest of the six months measured.
