Why the default cadence fails for one or the other
**ADHD-default cadence:** Flexible. Energy-driven. Variable intensity. Long deep-work sessions punctuated by recovery troughs. Strategic decisions in peak windows. Calendar light. Per Russell Barkley at russellbarkley.org and the CHADD reference at chadd.org, this matches the ADHD brain's natural ultradian rhythms + dopamine economy.
**Neurotypical-default cadence:** Predictable. Same-time-same-place. Daily standup. Weekly 1:1. Quarterly OKRs. Clear handoffs. Per HBR at hbr.org and APA at apa.org, this matches the neurotypical executive function pattern + supports systematic execution.
**The friction:** ADHD co-founder forced into neurotypical cadence feels stifled, low-energy on routine meetings, suboptimal output on rigid schedules. Neurotypical co-founder forced into ADHD cadence feels unmoored, unable to plan, frustrated by missed commitments + variable intensity.
**The pattern most pairs accidentally adopt:** One brain dominates the cadence + the other suffers. Per ADDitude Magazine at additudemag.com and the ADDA at add.org, this is the central operating-cadence failure mode of ADHD/neurotypical co-founder pairings.
