Original
Project management for modern teams.
Social Proof
“Trusted by 14,000+ teams to ship on time.”
Specific numbers convert better than generic claims.
Loss Aversion
“Stop missing deadlines because your team can't see what's in progress.”
Loss-framed JTBD copy outperforms aspirational benefit copy.
Authority
“The PM tool used by 3 of the YC top-10 companies.”
Authority signals reduce evaluation friction for trial signups.
Scarcity
“Free for the first 25 teams — invitation closes Friday.”
Genuine deadline-bound scarcity raises CTR without trust loss.
Reciprocity
“Get our free 27-page sprint planning playbook — no signup.”
Pre-commitment value builds reciprocity-based intent.
