What developer tools actually need
- The right channel. Many developers and founders discuss tools on X; tutorials live on YouTube; B2B buyers read LinkedIn and newsletters.
- Small, focused creators. Niche practitioners often beat big accounts. See why smaller creators outperform.
- Low fixed cost. You'll test before you scale, so annual contracts hurt.
- Attribution to signups, not just views.
- Increasingly, an API. Teams want an agent to do the coordination.
The platforms
Transformer: X-native, pay per verified post, built for agents
Brands paste their website, get suggested X creators with a reason and a suggested price, and send each an offer for one X post with the ask, link and price prefilled. Sending is free; the brand pays when a creator accepts, the creator posts after payment, and the payment is released when the post is verified live, from the creator's account, with the link and X's Paid partnership label. Creators keep 80%. Everything is available over an MCP server, CLI and REST API. Limits: X only today; no webhooks yet. See How Transformer works.
Passionfroot: multi-channel B2B sponsorships
A B2B creator marketplace where creators publish storefronts and brands book them, across LinkedIn, newsletters, YouTube, podcasts and more. Fees per its pricing page: 2% paid by the brand on direct deals, 15% when Passionfroot matches the deal. See Transformer vs Passionfroot.
ThoughtLeaders: YouTube sponsorships
A sponsorship marketplace and data platform focused on YouTube (with podcasts and newsletters), offering managed campaigns and sponsorship data. A good fit if your developers learn from YouTube tutorials.
Favikon: B2B creator discovery
A discovery tool with strong LinkedIn coverage across nine networks, including X; widely recommended for B2B. It finds creators; you run the deals.
Modash: discovery on consumer platforms
A large database of Instagram, TikTok and YouTube creators, with payments on higher plans. It doesn't cover X or LinkedIn. See Transformer vs Modash.
GRIN, Upfluence, Aspire, CreatorIQ: full suites
Built for e-commerce and consumer brands running many creators year-round: gifting, affiliates, CRM and reporting. Powerful, but the fixed costs and contracts are more than most early developer-tool programs need. See our comparisons with GRIN, Upfluence, Aspire and CreatorIQ.
