Curated AI Stack · Podcast hosts and producers selling 2–8 sponsorship slots per quarter
Podcast Sponsor Outreach Stack for Independent Shows (2026)
Sponsor outreach for indie podcasts is a numbers game with decent personalization — not 400 identical pitches. Apollo finds contacts, Lavender polishes subject lines, HubSpot free CRM tracks stages. Add Salesloft only when you are sending 50+ sequenced emails/week. Budget: $0–80/month depending on Apollo tier. Claude helps research briefs; it does not replace listening to the prospect’s last earnings call.

How we curated this stack
This stack pairs 3 core and 2 supplementary tools around one weekly workflow. Tools in curated stacks are evidence-checked on a weekly schedule: pricing is read from the vendor page and compared with the catalog band, public user reports from the last 90 days are collected with sources, and a person reviews the result before it is published. The check date and sources sit under each tool above; job-in-stack copy is editorial, not a hands-on test claim.
