Between October 2024 and March 2025, uithub experienced three distinct organic viral events on X (Twitter), each generating 100,000+ pageviews. The events established uithub's credibility as a widely-adopted developer tool and formed the core of Jan Wilmake's fundraising pitch in early 2025.
The first viral event brought uithub to a wide developer audience on X for the first time. Traffic exceeded 100,000 pageviews. The trigger and specific post are not recorded in the notes, but this event established the pattern that would repeat.
The second viral event originated in the Japanese developer community — Jan noted that the posts driving traffic were in Japanese and essentially all traffic came from Japan during this spike. This event is notable for demonstrating that uithub's utility transcended language barriers and had organic adoption in a market Jan had not specifically targeted.
Coinciding with openapisearch also going viral in March 2025, uithub had its third 100k+ traffic spike. This event, combined with the openapisearch launch, represented the peak of Jan's public visibility in Q1 2025.
Jan documented consistent baseline engagement between viral events: approximately 500–2,000 daily active users with repeated usage patterns.[1] This demonstrated that the viral events were driving genuine retention rather than one-time curiosity visits.
Jan described the three viral events to Ryan Hoover in April 2025 as evidence of organic product-market fit: "Uithub has organically gone viral 3 individual times on Twitter: October last year: 100k+ pageviews / In December: 100K+ pageviews (Posts in Japanese, all traffic from Japan only) / Last month: 100K+ pageviews again."[1]
The viral events underpinned Jan's $250,000 pre-seed fundraising pitch and attracted attention from Enes_Akar (Upstash, who began sponsoring at $100/month in May 2025), Ryan_Hoover (Weekend Fund investor inquiry), and Ben_Tossell (investment interest). They also contributed to Jan's initial outreach to the Cloudflare DevRel team.
A fourth viral event occurred in November 2025 — while Jan was travelling in Vietnam. Jan observed this surge upon returning home and noted the irony.
