10+ years in partner program strategy, GTM operations, channel strategy, or non-technical product management - ideally with direct exposure to accounting-firm or practice-management economics (client advisory services, referral/rev-share models, how a firm owner actually evaluates a partner program), not just SaaS partnerships. Own the P&L for the long-tail segment of the channel - cost per partner, cost per tier, cost of benefit delivery and support, and margin by tier, including rebate envelopes, run-rate floors/ceilings, and anti-stack rules - holding the line on profitability as adoption and scale increase, while influencing (not owning) the channel''s overall P&L so long-tail growth doesn''t quietly erode economics elsewhere in the portfolio.
