Comparison
FirstPromoter vs PartnerStack
The overlap between these two is smaller than category labels suggest. FirstPromoter is mid-market affiliate software: deep subscription tracking, campaigns, tax collection, priced by promoter tiers, operable by a growth team. PartnerStack is an enterprise ecosystem play: platform plus 100k+-partner network plus reseller/referral/affiliate motions, sold through demos and annual contracts.
What PartnerStack uniquely offers — network distribution, partner compliance workflows, agency/reseller management — matters when partnerships are an organized function with targets. What FirstPromoter offers — same-day start, subscription-correct math, W-9/W-8BEN flows — matters when a lean team needs the channel working this week.
Economics diverge sharply. FirstPromoter's tiers step with promoter counts but stay software-priced; PartnerStack combines platform fees with percentage-of-payout takes, which compound as partner earnings grow — defensible at ecosystem scale, punishing below it.
Ask one question: does my org chart contain partnerships headcount? Yes → PartnerStack conversation. No → it doesn't, regardless of how impressive the network deck is.

FAQ
FirstPromoter vs PartnerStack — FAQ
We have 300 promoters — is FirstPromoter enough?
Mechanically yes; economically watch the promoter-count curve. If tier jumps sting, flat-unlimited-affiliate alternatives (Sentalong Growth/Scale) decouple cost from recruitment.
Does PartnerStack's network justify its economics for us?
Model sourced-partner revenue against combined platform + take-rate costs over 24 months. Networks shine when sourced volume is high-margin relative to fees; otherwise direct recruitment through cheaper infrastructure wins.
Who migrates between these, and why?
Upward (FirstPromoter→PartnerStack): reseller motions and governance demands. Downward: renewal quotes reflecting success plus admin weight nobody can staff. Both migrations are common and survivable — plan export/import early.
Verdict
Partnerships-as-a-function → PartnerStack earns it. Everyone else → FirstPromoter-class self-serve tooling; consider flat-pricing challengers if promoter-count tiers or payout percentages bother your finance model.
