Funded startups + public repo + CTO / technical founder shortlist
Date: 2026-04-12
Action
Use this as tonight / tomorrow build list. Nango removed. PostHog removed. Bigger loose fits trimmed. 21st.dev added.
Missing decisions
- Keep only strict 5-15 teams, or allow a few 11-50 teams if product fit is sharp?
- CTO-only, or OK to message technical co-founders when title is close enough?
Risk
- Titles and team size drift. Re-check on send day before using
CTOin copy.
Shortlist
| # | Startup | Funding signal | Profile | Public repo | Potential message | Note |
|---|---|---|---|---|---|---|
| 1 | Notte | YC S25 + public $2.5M pre-seed coverage | Lucas Giordano: LinkedIn | nottelabs/notte | Notte feels like exact kind of infra team where product, sessions, and developer UX create invisible coordination debt fast. | Small, sharp fit. |
| 2 | Moss | YC F25 / YC-backed | Harsha Nalluru: LinkedIn | usemoss/moss | Moss sits in zone where tiny infra teams move absurdly fast until context starts leaking between product, eng, and support. | Small team, strong fit. |
| 3 | Kernel | Backed by Accel + YC; company says $22M raised | Rafael Garcia: LinkedIn, GitHub | kernel/cli | Kernel building browser infra for agents means auth, sessions, and execution state all collide early. That usually gets painful before headcount catches up. | Strong fit. |
| 4 | Novu | Raised $6.6M seed | Dima Grossman: LinkedIn, GitHub | novuhq/novu | Novu has classic open-source infra shape: fast product surface, lots of user touchpoints, hidden state everywhere unless someone makes it visible. | Medium team, still usable. |
| 5 | Signadot | Raised $4M led by Redpoint | Anirudh Ramachandran: LinkedIn | signadot/signadot | Signadot lives in exact microservice-testing pain cave where tiny teams burn time on invisible blockers and cross-team handoffs. | Strong fit. |
| 6 | Inngest | Public $3M seed, later $6.1M | Dan Farrelly: LinkedIn | inngest/inngest | Inngest feels like kind of workflow infra company where every gain in execution speed creates more coordination load behind scenes. | Strong fit. |
| 7 | Meilisearch | Public €1.5M then $15M Series A | Clément Renault: GitHub, Author page | meilisearch/meilisearch | Meilisearch has strong OSS-to-company motion. Those teams usually need sharper visibility because community, product, and revenue all pull on same builders. | Medium / bigger. |
| 8 | Medusa | Raised $8M seed | Oliver Windahl Juhl: LinkedIn | medusajs/medusa | Medusa feels like team where open-source momentum and customer complexity create lots of invisible work that does not show up in sprint boards. | Medium / bigger. |
| 9 | s2.dev | Raised $3.85M seed from Accel | Stephen Balogh: LinkedIn | s2-streamstore/s2 | s2.dev is right in agent-state territory: tiny infra team, durable streams, and lots of ways for execution context to go missing between backend and frontend. | Very strong fit. |
| 10 | Trigger.dev | YC W23 + public $16M Series A | Eric Allam: LinkedIn | triggerdotdev/trigger.dev | Trigger.dev has exact workflow / background-job shape where every product gain can create more invisible ops and support load behind scenes. | Team size around 9 on YC. |
| 11 | TensorZero | Public $7.3M seed | Viraj Mehta: Site | tensorzero/tensorzero | TensorZero is in painful layer where evals, inference, and product feedback loops all move fast and hidden work compounds quickly. | Likely small; strong OSS signal. |
| 12 | Qdrant | Public $7.5M seed | Andrey Vasnetsov: CV | qdrant/qdrant | Qdrant sits in category where infra teams move fast until customer asks, benchmarks, and core database work start fighting for same attention. | Medium / bigger. |
| 13 | ParadeDB | YC S23 + public $12M Series A | Ming Ying: LinkedIn | paradedb/paradedb | ParadeDB feels like kind of tiny database company where every new win creates more context spread across product, docs, benchmarks, and customer pressure. | Strong fit, small focused team. |
| 14 | 21st.dev | YC W26 + public pre-seed coverage | Sergey Bunas: LinkedIn, site | 21st-dev/1code | 21st.dev is exactly kind of fast-moving product where OSS traction, agent infra, and shipping speed can create a lot of invisible coordination drag very quickly. | Founder/CTO public; very relevant. |
| 15 | Langfuse | YC W23 + public $4M seed | Max Deichmann: YC, HN hiring snippet | langfuse/langfuse | Langfuse sits in LLM infra layer where evals, prompts, and debugging create constant hidden work unless execution state is visible across team. | 2-10 on LinkedIn. Strong fit. |
