Backed by research
Every design choice on Cykee comes from a piece of published research. Not vibes. Not marketing. Here's what we read, who wrote it, and what we built from it.
01 — Blurred photos
Eli Finkel and Paul Eastwick's decade of work on attraction has shown, again and again, that photo-based filtering doesn't predict whether two people will actually click in person. Chemistry shows up in voice, in cadence, in the things someone says when they're trying. We built the order of revelation to match what the research already knew: face last, words first.
02 — The 38-minute date
Arthur Aron's 1997 paper — the one journalists later called "The 36 Questions" — showed that two strangers, given the right questions and enough time, can reach the kind of vulnerability most people take months to find. We took the time, took the structure, and built an entire date around it.
03 — Conversation Sparks
Aron's questions work because they escalate. They start light, get personal, and end at the kind of question you'd only ask someone you already trust. Layer that on top of what Harry Reis, Margaret Clark and John Holmes call Perceived Partner Responsiveness — the feeling of being uniquely understood — and you have one of the strongest known predictors of long-term satisfaction in a relationship.
04 — Photos only clear on mutual yes
Caryl Rusbult's Investment Model and Justin Kruger's Effort Heuristic describe the same insight from two angles: people value what they had to work for. When the reveal is earned by an actual conversation — not a deck swipe — it lands differently, and it sticks.
05 — The post-match gift
Norton, Mochon and Ariely's IKEA effect (2012) and the Effort Heuristic literature both point at one thing: physical, deliberate effort signals care in a way nothing digital can. A real gift, shipped to a real address by a real person, says "I planned this for you" louder than any badge or animation could.
06 — Baker-Miller pink — yes, the color
Alexander Schauss's 1979 research showed that a very specific pink — first painted on the walls of the Naval Correctional Center in Seattle by directors Baker and Miller — measurably lowered physical and emotional agitation. It is, to this day, the only color with peer-reviewed evidence behind its calming effect. So we built the whole brand around it. The pink you see on every Cykee surface is that pink.
07 — Cupido as mentor, not replacement
John and Julie Gottman's four decades of marriage research keep landing on the same conclusion: what makes a relationship last is not pickup tricks or clever lines. It's small bids for connection, the absence of contempt, the willingness to repair after a fight. Those are skills you build, not phrases you copy. A mentor can teach them. A ghost-writer can't.
08 — Free to date
The U.S. Surgeon General's 2023 advisory and Julianne Holt-Lunstad's foundational 2010 paper in PLOS Medicine put loneliness on the same mortality scale as smoking around fifteen cigarettes a day. Charging people to escape that is the wrong incentive. So we don't.
