David Spiegel

David Spiegel is a product and growth consultant based in San Francisco. He studied psychology at New York University with a focus on human cognition: how people perceive things, form intentions, and decide what to do next. That background informs how he approaches a product. Before changing a screen, he wants to understand what someone expects, what is unclear, and what might stop them from continuing.

At MD Exam, a 5 Axis Health brand, that meant redesigning patient intake and onboarding, then reworking how people understood the pricing, chose a product, and moved through checkout. He helped the business grow from 10,000 to more than 50,000 patients. His portfolio reports a 30% increase in conversion and a 76% increase in average order value from the purchase-flow redesign.

His work also extends to businesses where small changes reach a large audience. At Content IQ, he managed a portfolio of more than 20 publisher sites generating $40 million in annual advertising revenue and reports increasing revenue per session by 30–50%. At Sharethrough, a supply-side advertising platform, he was the product manager for ad formats and rendering across display, native, in-app, and outstream ads. An ad-format launch added $1.8 million in annual revenue during eight months in the role.

Testing has been part of his work since his first product internship at Fluent, where three months of A/B testing added more than $1.3 million in annual revenue. More recently, he helped Chargerless quadruple monthly sales after the first month of working together, improve return on Meta ad spend, and sell out its limited August launch batch earlier than planned.

The common thread is finding the point where interest stalls and making it easier for someone to continue. His current consulting and fractional work covers onboarding, activation, conversion, monetization, engagement, retention, and product strategy, with hands-on execution as part of the work.

Education and project results are described by Spiegel in his portfolio and in details shared directly with Expert Shortlist on September 8, 2026. Public portfolio: David Spiegel — work and approach.

Spiegel’s Memelord case supports a specific diagnostic purchase: interpreting onboarding, engagement and retention behavior and prioritizing improvements. The narrow published case warrants inclusion below dedicated repeatable SaaS onboarding programs and clearly scoped messaging services.

David Spiegel’s current CV describes a Memelord consulting assignment across a B2B agent platform and a consumer app. He studied product usage to understand onboarding, engagement and retention, identified behaviors separating active or subscribed users from those who churned, and delivered a prioritized plan of improvements and tests. Memelord’s current developer documentation describes hosted API software with account usage balances and billing.

That is a specific SaaS onboarding diagnosis to discuss if your team needs help interpreting how new users progress. The account supports analysis and recommendations; it does not establish a shipped SaaS redesign or an independently verified conversion result. His current site invites consulting work. Agree whether your engagement ends with a plan or includes subsequent design and implementation, and identify who will maintain the activation measurement.
