## Cradle

Cradle is a protein engineering platform that applies machine learning to the design and optimization of proteins. Instead of optimizing one property at a time, teams use Cradle to work on potency, specificity, expression, thermostability, and manufacturability simultaneously — compressing the number of experimental rounds needed to reach a candidate that meets a target profile.

The platform covers a broad range of protein classes, including antibodies for ADC and multispecific formats, enzymes that need to hold up in hostile conditions, vaccine antigens that must keep their shape outside the lab, and peptides that need potency within tight constraints even from small datasets. It works whether or not a starting protein already exists, and it learns from the customer's own experimental data, including results from previous failed campaigns, so each design round is better informed than the last.

Cradle is positioned for multiple roles in an organization: experimental scientists get point-and-click candidate design and optimization; computational scientists get the same functionality exposed through an API for scripting and integration; and R&D leadership gains a compounding advantage from every experiment their teams have run. Security is a stated priority, with ISO 27001 and SOC 2 Type II certification and hosting on Google Cloud. Pricing is not published — interested teams discuss their project with Cradle to get terms.

**Pricing & Plans:** Pricing is not publicly listed. Cradle uses a contact-for-pricing model where teams discuss their project and program scope directly with the company; a licensing track and API access are offered alongside the core platform.

- **De novo protein design:** Start from a target or your own sequence and have Cradle design an optimized plate of candidates informed by your data and domain knowledge.
- **Parallel multi-property optimization:** Improve efficacy, developability, and manufacturability in parallel rather than one property at a time, compressing time to a target profile.
- **Closed-loop learning from experimental data:** Every round incorporates results from the previous one, so experimental data compounds across campaigns and prior failed programs stay useful.
- **Full API access:** Everything in the web application is exposed through the API, so computational teams can script campaigns and wire Cradle into existing pipelines.
- **Enterprise-grade security and compliance:** ISO 27001 and SOC 2 Type II certified, hosted on Google Cloud with data isolation and continuous monitoring for enterprise deployments.

**Strengths:** Optimizes multiple protein properties in parallel rather than sequentially, which can cut the number of experimental rounds; Learns from a customer's own experimental data, including negative and failed results; Covers antibodies, enzymes, vaccines, and peptides in one platform; Full API parity with the web app supports computational and automated workflows

**Limitations:** No self-serve trial or published pricing, so evaluation requires a sales conversation; Requires in-house experimental capability to generate the assay data that drives the models; Cost and onboarding are geared to organizations rather than individual researchers

## Surf

Surf positions itself as the intelligence layer for open financial markets. The core experience is conversational: you ask a question about a token, a protocol, a company, or a market move, and the system returns an answer grounded in live market feeds, onchain events, SEC filings, and news, with the underlying sources cited so you can verify the reasoning. Around that chat experience, Surf layers a set of named products such as CryptoPulse and Cryptopedia, plus an in-browser Studio for building analysis.

What separates Surf from a generic chatbot is the data plumbing behind it. The company says its datasets are kept current, structured, and unified across fragmented sources before any model touches them, which matters because much of crypto data is scattered across exchanges, chains, and regional venues. Surf also highlights its coverage of hard-to-source markets, including multilingual Asian centralized exchange data, as a differentiator for institutional research.

For builders, Surf exposes the same intelligence through an API, an MCP server, a CLI, and reusable agent skills, so a research desk can embed crypto and equities context directly into its own agents and internal tools. Surf states it is used by more than 500,000 users across 700-plus organizations, and its developer layer is documented separately for teams that want to integrate rather than click. Surf is operated by Cybertino Inc. and is not affiliated with any exchange or broker; outputs are research assistance, not investment advice.

**Pricing & Plans:** Surf publishes a tiered pricing page covering Free, Pro, and Max plans alongside API credit packages, with annual billing options and Studio credits bundled at higher tiers. Exact figures change over time, so check the official pricing page before purchasing.

- **Cited conversational analyst:** Ask questions about tokens, protocols, or equities in plain language and receive answers backed by visible sources rather than unsupported assertions.
- **Unified multi-source data:** Market prices, onchain events, SEC filings, and news are normalized into one structured layer so the model reasons over consistent inputs.
- **Developer integration layer:** API, MCP server, CLI, and agent skills let teams wire Surf intelligence into their own agents, dashboards, and internal research workflows.
- **CryptoPulse and Cryptopedia products:** Purpose-built modules for tracking market-moving developments and for looking up structured context on projects and assets.
- **Coverage of hard-to-source markets:** Surf emphasizes structured multilingual data from Asian centralized exchanges, a category many Western data vendors handle poorly.

**Strengths:** Answers come with citations, which makes verification practical rather than a leap of faith.; Covers both onchain crypto data and US equities in a single interface, useful for cross-asset research.; Genuine developer surface area: API, MCP, CLI, and agent skills, not just a chat box.; Institutional framing and published case studies signal real deployments with funds and exchanges.

**Limitations:** It is a research and intelligence tool, not a trading or execution venue, so it will not place orders for you.; Deeper data access and higher usage tiers sit behind paid plans and API credits.; Coverage quality varies by asset and venue; niche or thinly traded markets may return thinner answers.
