How Limelight validated the B2B creator market by interviewing 100+ creators before building | David Walsh
Limelight is building the infrastructure layer for B2B creator marketing, processing payments and managing campaigns for companies spending six figures monthly on creator partnerships. With $2.1 million in funding from Signal to Noise Ratio, Ascend Ventures, Savion Ventures, and strategic angels including the head of AI at Amazon and the former Chief Product Officer at Lyft, Limelight powers creator programs for Clay, Webflow, ZoomInfo, and Bill.com. In this episode of BUILDERS, we sat down with David Walsh, Founder and CEO of Limelight, to learn how he validated the market by interviewing 100+ creators, why he deliberately chose not to build an agency despite customer demand, and how his platform tracks engagement data at scale to prove ROI for performance-focused buyers.
Topics Discussed:
- The pivot from referral software to B2B creator infrastructure after 100+ creator interviews
- How creator attitudes shifted from refusing brand partnerships to actively monetizing
- Clay’s playbook: building custom Clay tables for creators before asking them to post
- Why Limelight chose to power agencies rather than compete with them
- The data infrastructure required to justify $100K+ monthly creator budgets
- Tracking organic engagement, converting content to paid ads, and attributing pipeline
- The split between brand/social buyers and performance/demand gen buyers
- Launching social listening to challenge legacy social media management platforms
GTM Lessons For B2B Founders:
- Validate with 100+ user interviews before pivoting: David didn’t just chat with a handful of potential users—he conducted and recorded over 100 interviews with B2B creators, asking detailed questions about monetization interest, partnership preferences, and content strategies. He then repeated this process with marketing leaders. This level of research rigor before committing to a pivot is rare but critical when entering emerging categories. The depth of qualitative research gave him conviction to make a contrarian bet when most creators were still refusing brand partnerships.
- Build where network effects are structural, not hoped for: David specifically chose a creator marketplace after a previous marketplace failure because the unit economics included built-in virality. When Limelight pays a creator $10,000, that creator has tens of thousands of followers who see the transaction result (the sponsored content). Every payment notification becomes inbound interest. He understood that in consumer marketplaces you compete on supply quality, but in creator marketplaces the supply actively markets your platform. Founders should identify whether their marketplace has structural network effects in the transaction itself, not just theoretical ones.
