8 UGC and Creator Marketplace Tools for B2B Brands Testing Influencer Spend

Last updated: October 28, 2026

Influencer marketing used to be a consumer-brand game. Now B2B buyers follow operators, practitioners, and niche newsletter writers who shape what they buy, and a sponsored post from a trusted RevOps creator can outperform a month of paid ads. The problem is finding the right creators and managing the work without hiring an agency. A B2B creator marketplace or UGC platform handles discovery, briefs, payments, and content rights. Here are 8 tools for B2B brands testing creator and UGC spend, scored on creator quality, turnaround time, and fit for B2B audiences.

UGC vs creator partnerships: know which you’re buying

These platforms split into two models. UGC platforms pay creators to make content, such as testimonial-style or product demo videos, that you publish on your own channels or run as ads. Creator partnership platforms pay creators to publish to their own audience, such as a LinkedIn post, newsletter sponsorship, or podcast mention. B2B brands usually get more from the second model, because the value is the creator’s trust with a specific audience, not just the video.

1. Passionfroot

Passionfroot is built around B2B creators, particularly LinkedIn creators, newsletter writers, and podcasters. Brands can browse creators, see their sponsorship packages and prices, and book collaborations with briefs and payments handled in one place. It’s one of the most B2B-relevant marketplaces available.

Best for: B2B brands sponsoring LinkedIn creators and newsletters.

2. Favikon

Favikon is a creator discovery and analytics platform with especially strong LinkedIn coverage, including rankings of top creators by niche and country. It’s useful for identifying which B2B creators actually have engaged audiences before you reach out, rather than relying on follower counts.

Best for: Finding and vetting LinkedIn creators by niche.

3. Modash

Modash is a large-scale creator discovery tool covering Instagram, TikTok, and YouTube, with audience analytics, fake follower checks, and outreach. It’s more consumer-focused in coverage, but useful for B2B brands testing short-form video on those platforms.

Best for: Discovering creators on TikTok, Instagram, and YouTube.

4. Insense

Insense sits between simple marketplaces and enterprise platforms, with campaign management covering creator discovery, briefs, content approvals, licensing, and running creator content as ads. It’s primarily used by DTC brands, but its workflow suits B2B teams testing paid social with creator content.

Best for: Teams running creator content as paid social ads.

5. Billo

Billo is a UGC-only platform focused on short-form video, where creators apply to your brief and deliver videos quickly. It’s built for ecommerce products, so B2B brands should brief carefully, for example asking for screen-recorded walkthroughs or talking-head explanations rather than unboxing videos.

Best for: Fast, affordable short-form UGC videos.

6. Trend by soona

Trend is a self-serve UGC marketplace with a network of vetted creators, transparent pricing, and full content rights on each project. It’s a quick way to test UGC-style content without long contracts.

Best for: Testing UGC with transparent pricing and clear rights.

7. Collabstr

Collabstr is a marketplace where creators list packages with fixed prices across platforms, so brands can book without negotiation. Its B2B creator pool is smaller than Passionfroot’s, but its pricing transparency is useful for budgeting early tests.

Best for: Small tests with fixed-price creator packages.

8. Aspire

Aspire is an influencer relationship management platform for running ongoing creator programs, with discovery, outreach, contracts, content tracking, and payments. It’s more of a program management system than a marketplace, suited to teams scaling from a few test partnerships to a sustained creator program.

Best for: Scaling creator programs beyond one-off tests.

How to test a B2B creator marketplace without wasting budget

Start small: pick three to five creators whose audience matches your ideal customer profile, not just your industry. Ask for past sponsored post results and audience breakdowns. Give creators your key message but let them write in their own voice, since heavily scripted posts underperform. Track results with unique links and codes, and ask new leads how they heard about you, since much creator impact happens through private shares and later branded searches. Creator partnerships also pair well with internal voices, so consider combining them with employee advocacy platforms, and repurpose creator videos using the short-form video tools B2B brands use.

The verdict

For most B2B brands, Passionfroot and Favikon are the best starting points because they focus on LinkedIn and newsletter creators who reach business buyers. Use Billo, Trend, or Insense if you want UGC-style video for ads. Modash and Aspire make sense once you’re running creator programs on consumer platforms or at scale. Treat the first quarter as an experiment, and judge success on qualified pipeline and branded search lift, not likes.
