Receipts
Traction claims posted this week, as the founders posted them. Each one links to its post; Batchwatch checks that the post says it, not that it is true.
- RATLOG: @_charlieweise says RATLOG has "$400M in launch reservations signed." He says the first engine was hot-fired 4 months in, from a basement, for under $30K. This is a single post with no customers named. post
- Boat: @AniC_dev says Boat serves more than 12k vCPUs and 24TB of RAM, grew 7.5x in 2 months and saves customers more than $7.5M this year. He also says daily VM spawns doubled in 7 days. post 1 · post 2
- Native: @BenjaminBekken says Native passed $1.3M in gross volume sales in its first six months. He also says its Norn model is live for 2,200+ businesses. post 1 · post 2
- Caveman: @julius_brussee says Caveman has 111k GitHub stars and passed Supabase in stars on Oct 14. Stars measure attention, not revenue. post 1 · post 2
- CONUS: @VincentPaffrath says CONUS is used in 20+ hospitals. @greybaker repeated the figure as "live in 20 hospitals." post 1 · post 2
- Frontrunner: @mayanayyar1 says she had 24 demos on her calendar in one day after her launch post. That is demand for demos, not signed customers. post
- Veeza AI: @alymoursy claims 7x user growth since going live on the YC directory "a month and a bit" ago. He gives no base number and is targeting "100 KAY by Demo Day." post 1 · post 2

Breakouts to watch
Companies outside the top five whose mentions grew fastest.
- Praxis: Mentions went from 0 to 6.7 per day after @KhraminaDianka's Oct 15 launch post (9.5k views). Most mentions are replies about its 62% admin-time figure and per-step lawyer approval. post 1 · post 2
- Deploy: Mentions went from 1 to 11 per day after the Oct 14 YC launch. Most are congratulatory replies, plus one question about its moat, so treat this as weak signal. post 1 · post 2
- antimattr: Mentions went from 0.8 to 5 per day, driven by skeptical replies on privacy and whether a phone and earbuds already do the job. The CEO also posted an 8-part history thread. post 1 · post 2
The batch mood
Agent compute is crowded and competing on price. Boat says it charges $0.009/h and is 9x cheaper than E2B and Daytona, Maritime sells an Android MCP at $1/month, and Terse and Agent 37 are pitching durable state and persistent sandboxes. post 1 · post 2
Robotics infrastructure clustered in one week: Dreamscale's cloud inference, Deploy's launch and Runtime.si's evals. Runtime.si reported a frontier model going from 0/20 to 8/20 successes on a task through skill refinement. post 1 · post 2
Free work is a common way to win demos. Simulithic pays $50 if it finds no bugs, OpenSEO runs free audits for anyone who replies, and Clean offers 10 free prospects with buying signals. post 1 · post 2
Demo Day countdown
44 days to YC Fall 2026 Demo Day, Wednesday, December 2.
Meet first: Boat. Boat has the most detailed usage claims in the batch (12k vCPUs, 7.5x in two months), and outside users like @g48in describe real workloads on it. All figures are self-reported, so verify them. post 1 · post 2
