The call

Cradle has real pharma deals and private data, but sits in a crowded field of similarly funded AI protein design rivals with no new capital raise in 20 months.

Cradle makes artificial intelligence software that helps pharmaceutical companies design new drugs faster by learning from real lab experiments. It is hard to replace because it has built real relationships with major pharma companies like Bayer and Lundbeck, with long-term contracts, and it keeps its lab data secret so competitors cannot use it to train their own systems. However, Cradle faces serious competition from other AI companies doing almost the same thing, like Chai Discovery and Nabla Bio, and these rivals have more money in the bank while Cradle has not raised new funding in over a year and a half. The one thing that could change everything is if Cradle raises significant new funding soon and signs up more than half of the top 25 pharma companies as customers, which would prove its lab data advantage is creating real lock-in rather than just temporary deals.

Why
01
AI pressure: Chai Discovery, Nabla Bio, and open frontier models like AlphaFold3 and Chai-2. Rivals run near-identical AI design platforms, and public models could let pharma build the modeling layer in-house. Could AI do the core job? Only partly.
02
Bigger players: Isomorphic Labs (Alphabet-backed) and big pharma building internal AI teams. Alphabet-backed rivals and pharma's own AI groups could pull budget away from independent platforms like Cradle. Could a giant copy it? No, they are blocked.
03
What protects it. Proprietary wet-lab data retrained biweekly, contractual IP-neutrality promises, and multi-year deals with Bayer and Lundbeck.
What would change this call
Cradle announces a Series C round within 12 months. Shows Cradle can match rivals' war chests instead of falling behind on funding.
Cradle's top-pharma logo count moves past 8/25 or a named logo defects to Chai or Nabla. Tests whether Cradle is pulling ahead or losing ground in the finite 25-buyer market.
Bayer or Lundbeck publicly expands, renews, or ends its collaboration with Cradle. Shows whether Cradle's flagship pharma partnerships are deepening or stalling.
Key numbers
  • $73M Series B raised, over $100M total funding (2024-11-25)
  • 8 of top 25 global pharma companies are customers (2026-06-03)
  • Paying SaaS projects grew 15x year over year (2025-06-27)
Named risks
  • No Series C raised in 20 months while rivals Chai Discovery and Nabla Bio stockpile capital. Severity: high
  • Contested 25-buyer pharma market with near-identical competitor moats offering no clear leader. Severity: high
  • Revenue undisclosed, limiting external validation of growth claims. Severity: medium
  • Frontier biomolecular models could commoditize the modeling layer Cradle depends on. Severity: medium
  • Marquee pharma logos could be won by better-funded pure-play rivals. Severity: medium

Questions people ask
Is Cradle profitable in 2026?
Cradle does not disclose revenue, and CEO Stef van Grieken has declined to state figures publicly, as reported by Sifted on 2025-06-27. The company is privately held and venture-funded, with no profitability data available in any public source as of mid-2026.
Has Cradle raised a Series C round?
No. As of July 2026, Cradle's most recent funding event remains its $73M Series B led by IVP, announced 2024-11-25, bringing total funding to over $100M. No subsequent priced round has been publicly reported in the 20 months since.
Who are Cradle's biggest competitors?
Cradle competes directly with Chai Discovery and Nabla Bio, both pure-play AI protein design platforms, plus Absci and Generate:Biomedicines which combine AI with their own drug pipelines. Chai Discovery had signed Eli Lilly, Pfizer and Novartis by 2026, per Index Ventures.
Could AI replace Cradle's protein design platform?
Unlikely soon. Cradle's CEO argues in a 2026-07-14 R&D World interview that frontier models like AlphaFold3 and Chai-2 are commodity ingredients, while the real bottleneck is proprietary wet-lab data and slow, costly experimental feedback loops that AI agents cannot shortcut without lab infrastructure.
Who owns Cradle and who funds it?
Cradle is privately owned, founded May 2021 by Stef van Grieken and Elise de Reus. It is backed by Index Ventures, Kindred Capital, and IVP, which led its $73M Series B on 2024-11-25, the largest of its three funding rounds totaling over $100M.
Which pharma companies work with Cradle?
Cradle's disclosed pharma partners include Bayer (3-year antibody discovery collaboration announced 2026-01-07) and H. Lundbeck (two CNS antibody programs, 2026-06-03), alongside named customers Novo Nordisk, Johnson & Johnson Innovative Medicine, Novonesis, Grifols and Ginkgo Bioworks.
