The moment a marketing agency or SaaS company sends a survey to a client's customer list, they realize the survey looks like the survey vendor's product — not theirs. Custom CSS access is either paywalled at enterprise tiers or flat-out broken for edge cases like multi-program registration pages. They're stuck either paying for an enterprise seat they barely need or shipping something that embarrasses them in front of a client.

Survey vendors have no structural incentive to fix this properly. The vendor's brand showing through is free advertising, and fully flexible theming is expensive to build and support — so they expose just enough customization to reduce churn while keeping the hard parts locked. The buyer (the agency) is different from the user (the end respondent), and respondents don't complain in G2 reviews, so the pressure never gets loud enough.

What users actually describe is granular: backgrounds and text they can't touch, email templates they can't restyle, registration portals they can't differentiate per program. The gap isn't 'add a logo' — it's building a rendering layer that sits between the survey data and the final HTML output, giving designers real control without them needing to touch the survey vendor's internal config.

This is a business and not a feature because an agency has this problem on every new client engagement. They don't pay once and move on — every new client triggers the same limitation, the same workaround conversation, the same brand embarrassment risk. A recurring workflow problem for a buyer who bills clients monthly is the right shape for a subscription.

What to build

Build a design layer that connects to survey tools via embed or iframe, intercepts the rendered output, and applies per-client CSS/HTML templates — including email wrappers and registration pages — without touching the underlying survey data or logic.

Where to start

Start with AhaSlides users running live event surveys for corporate clients, where brand embarrassment on a projected screen in a conference room is immediate and undeniable — the pain is visible and the buyer is right there.

The hard part

Getting reliable access to the rendered survey output across different vendors without relying on undocumented APIs that break on product updates — you'll need to choose one vendor to go deep on first and resist the urge to abstract too early.

How it makes money

Monthly subscription per agency seat, with per-client workspace add-ons once an agency exceeds three active client brands.
