As answered by people managing BirdseyePost and YieldStack.
BirdseyePost's answer
Our journey began in with an AI-driven platform for automated, personalized email marketing (launched long before AI was the cool new kid on the block). We helped eCommerce brands connect with customers through the inbox— delivering highly targeted messages that felt like they were crafted by a dedicated team.
As we watched our partners thrive with Birdseye, we saw an opportunity to elevate their growth even further. We realized that while digital engagement is crucial, it’s just one piece of a much bigger puzzle. True brand loyalty requires more than clicks—it requires a deeper, more memorable connection.
That’s where BirdseyePost comes in. We took our core mission—helping businesses grow through meaningful, personalized customer interactions—and brought it into the physical world.
We’re making direct mail as impactful and easy to use as digital marketing, but with the unique, personal touch that only a physical piece can deliver.
BirdseyePost offers a complete direct mail solution, combining our expertise in personalized communication with the power of precision targeting and beautiful design. From postcard campaigns that instantly capture opted-in leads to hyper-personalized, best-in-class designs, BirdseyePost turns direct mail into a dynamic, measurable growth channel.
Every postcard, every offer, and every message is meticulously crafted to resonate with your audience and strengthen your brand. Every postcard we deliver is designed to capture attention, spark curiosity, and build genuine connections—making your brand feel personal and unforgettable.
Our goal is to empower your brand to break through digital noise and leave a lasting impression that drives real results. We’re more than a direct mail provider—we’re a growth partner, combining the precision of data with the artistry of print to help your business achieve its next big milestone.
YieldStack's answer:
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
BirdseyePost's answer
Because most direct mail platforms stop at "send." BirdseyePost goes all the way to "send → capture → convert."
While competitors focus on batch-and-blast mail, BirdseyePost brings direct mail into the digital age with automation, instant lead capture, real-time tracking, and deep audience targeting—all in a single platform.
BirdseyePost makes direct mail smarter, speeder (launch a campaign in under a week), and trackable down the the individual. Our support team is available 24/7 to help you succeed.
YieldStack's answer:
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
BirdseyePost's answer
BirdseyePost transforms traditional direct mail into a fully automated, data-driven channel that integrates seamlessly with modern ecommerce marketing. Unlike other platforms, we don't just send postcards — we turn them into instant lead capture and conversion tools.
With SnapCapture™ for instant lead capture, SmartMailers for triggered sends, and real-time tracking, every postcard becomes a personalized, trackable conversion tool — not just a mailer.
BirdseyePost isn’t about sending more mail. It’s about sending smarter mail — that captures leads, personalizes every touch, and closes the loop with attribution and automation.

YieldStack's answer:
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
