About Second Half Full

30+ years of consumer adoption strategy. The intelligence platform built by the people who actually ran the model.

Decades of primary consumer research across industries — tech, software, now healthspan. Then we built and operated Elivate (2023–2025), an award-winning longevity services company, as the proof case. That operator experience is now the intelligence foundation for the whole category.

Why 2H Full Exists

87% of adults want to act on their healthspan. 95% aren’t.

The gap between intent and action is not a science problem. It’s a belief problem — and it follows the same pattern Deirdre has traced across tech, software, and consumer industries for 30+ years. 2H Full gives longevity businesses the consumer intelligence to close it.

“Bio age language activates. Longevity language can shame. The frame is optimization and performance — not aging.”

— 2H Full Research Finding
Our Origin

A career built on one question. A business built to prove the answer.

For 30+ years, Deirdre has applied the same research methodology to the same underlying question across industries: why do people who want a thing not actually do the thing? Tech, software, consumer goods — the adoption gap pattern is identical. Healthspan is the most important and least researched version of it.

From 2023 to 2025, we built and operated Elivate — an award-winning longevity services company delivering healthspan treatments directly to consumers — as the operational proof case for the 2H Full thesis. Two years inside the delivery model. 180 in-depth interviews. 5,000+ field interactions. Daily access to the exact customers we studied.

“Achieving 1,800 customers purely through word of mouth, boasting 47% repeat revenue from clients, and operating at a greater than 20% net profit margin per visit is outstanding.”

★ Stevie® Awards Judge · 2025 Women in Business Awards

We built and operated a category-defining model, learned what others are still guessing about, then pivoted to build the intelligence layer the category needs. Every longevity business we talked to had the same gap: deep product investment, almost no consumer intelligence. 2H Full exists to close it.

Experience

Decades of primary consumer research. The healthspan category is one chapter.

Deirdre has spent 30+ years conducting original primary research at major industry inflection points — tech, software, consumer — always asking the same underlying question: what finally moves people to act. The healthspan work is the most recent and most personally significant application of that career-long methodology.

180 In-Depth Interviews

5,000+ Field Interactions

5,000+ field interactions through the Elivate program (2023–2025). What people say, do, and decide in the moment — not in a survey.

Consumer Panel (2023–2025)

Longitudinal panel of 40s–60s consumers tracked through the Elivate program. Category attitudes, decision triggers, and belief shifts measured over time — not in a single survey sweep.

Daily Market Intelligence

Automated competitive intelligence running since May 2026. Five growth levers tracked across 60 companies, every day.

The Team

Built by people who’ve done this before — for the companies that defined it.

Deirdre Davi
Founder
30+ years of primary consumer research and behavior change strategy across industries — tech, software, consumer goods — always working at the inflection points where a new category collides with real human behavior. Founded Elivate (2023–2025) as a longevity services company: the operational test case for everything the research said should work. Built 2H Full to put what that combination revealed into the hands of every operator in the category.

Recent thinking

“The longevity category has a messaging problem. ‘Live longer’ activates fear. ‘Optimize your biology’ activates curiosity. Same science, completely different consumer response.”

“87% of people want to act on their healthspan. 95% aren’t. This is the most important business problem in the $1T longevity market — and it’s not a product problem.”
