Performance marketing · Austin, Texas
Turn ad spend into repeatable revenue.
Signal & Sparrow is a twelve-person digital marketing agency for B2B software, outdoor brands and regional healthcare groups that are tired of guessing which half of their budget works. We rebuild measurement, creative and landing pages together so every dollar can be traced to pipeline, appointments or wholesale reorders instead of vanity clicks.

Retail
Four disciplines, one weekly scorecard
We do not hand off a media plan and disappear. Strategists, designers and analysts sit in the same room every Monday to reconcile spend, creative fatigue and sales outcomes.
Paid search and shopping
We rebuild Google and Microsoft accounts from query-level data, split branded and non-branded bids, and write ad copy that matches the landing page headline word for word.
Paid social and creative
Short-form video, static tests and offer angles ship every two weeks with naming conventions your CRM can actually parse when leads arrive.
Landing pages that convert
Our in-house designers build fast pages in your stack with forms wired to your CRM, thank-you pages that set expectations, and heatmaps reviewed every Friday.
Lifecycle email and SMS
We map onboarding, nurture and win-back flows with plain-language copy tests, then report incremental revenue instead of open rates alone.

From marketing and revenue leaders
“They rebuilt our attribution in two weeks and finally gave our CFO a chart she trusts. We renegotiated our ad contracts with real numbers.”
“Creative used to live in a separate folder from media. Signal & Sparrow tests headlines and bids together, which sounds obvious and is rare.”
“Our cost per booked appointment dropped thirty-one percent without cutting clinic hours. The reporting is blunt and useful.”

Working together
Do you require a minimum ad spend?
We ask for at least fifteen thousand dollars a month in media so tests reach significance. Smaller budgets fit our Launch plan with fewer channels.
Can you work with our in-house team?
Yes. We often pair with internal designers or media buyers and document everything in shared playbooks.
Which platforms do you support?
Google, Microsoft, Meta, LinkedIn, TikTok and Pinterest, plus lifecycle tools like Klaviyo, Iterable or Customer.io.
How do you report ROI?
We agree on a primary revenue metric up front—pipeline, bookings or orders—and report incrementality where possible.
Tell us where spend feels fuzzy
Share your stack and monthly budget. We reply within two business days with a short loom, not a generic deck.
Ready for a scorecard you can defend?
Bring last quarter's numbers and we will show what we would change in the first thirty days.
