# Boston & Cambridge Startups We Cover in 2026: Biotech, AI Biology, and Hard Tech

> As of July 2026, directory companies we can honestly place in Boston–Cambridge or Greater Boston — plus related biotech coverage tied to Boston capital with HQ labeled elsewhere.

**Short answer (as of July 2026):** In our startup directory, companies we can **honestly place in Boston–Cambridge or Greater Boston** include [Boston Metal](/startup/boston-metal) (Woburn), [Boltz](/startup/boltz) (Boston / MIT-origin), [Ventus Therapeutics](/startup/ventus-therapeutics) (Waltham), [ROME Therapeutics](/startup/rome-therapeutics) (Boston), [IDRx](/startup/idrx) (Plymouth), [GC Therapeutics](/startup/gc-therapeutics) (Cambridge), [Curie.Bio](/startup/curiebio) (Boston), [Alpha-9 Oncology](/startup/alpha-9-oncology) (Boston; Vancouver ops), [Anagram Therapeutics](/startup/anagram-therapeutics) (Natick), [Nava Therapeutics](/startup/nava-therapeutics) (Cambridge), and [Mentari Therapeutics](/startup/mentari-therapeutics) (Waltham). Other biotech IDs we track are filed below as **related / HQ elsewhere** — useful if you follow Boston capital, not as local HQs.

### Boston–Cambridge & Greater Boston — startups we cover

HQ notes use public citations (company sites, CB Insights, press) because most startup JSON files omit an `hq` field. Where we say “commonly cited,” that is intentional.

|---|---|---|---|---|---|
| [Boston Metal](/startup/boston-metal) | Molten Oxide Electrolysis for lower-emission critical metals / steel pathways | Other / private; $75M deploy raise (May 2026 coverage) | Woburn, MA (Greater Boston) | Not fully mapped on startup JSON; see [funding note](/2026-boston-metal-75m-industrial-climate-tech) | [/startup/boston-metal](/startup/boston-metal) |

### How to read this coverage

- Directory map of companies we index with Boston–Cambridge evidence — not a “top startups” ranking (no invented valuations).
- Biotech-skewed because that is what we have ingested; Boston SaaS/cyber names are mostly still coverage gaps.
- Status matters: IDRx is acquired; ROME has acquisition press — useful as cluster evidence, not active raise targets.

### Related directory biotech — HQ elsewhere

Same `/startup/` IDs, often sharing syndicates with Boston-active capital (a16z Bio, ARCH). **Not** claimed as local HQs.

| Startup | HQ / label | Profile |
|---|---|---|
| [Hera](/startup/hera) — AI senior-care coordination | **New York, NY** (BCV has a Boston office; company is NYC) | [/startup/hera](/startup/hera) |
| [Gate Bioscience](/startup/gate-bioscience) — Molecular Gate medicines | **Brisbane, CA** | [/startup/gate-bioscience](/startup/gate-bioscience) |
| [Cartography Biosciences](/startup/cartography-biosciences) — antigen atlas / IO | **SF Bay (commonly cited)** | [/startup/cartography-biosciences](/startup/cartography-biosciences) |
| [Ona Therapeutics](/startup/ona-therapeutics) — ADCs for resistant cancers | **Barcelona** | [/startup/ona-therapeutics](/startup/ona-therapeutics) |

| [Inceptive](/startup/inceptive) — AI-designed mRNA | **Bay Area commonly cited** | [/startup/inceptive](/startup/inceptive) |
| [Patch Biosciences](/startup/patch-biosciences), [Phylo](/startup/phylo), [Santa Ana Bio](/startup/santa-ana-bio), [Orchestra Bio](/startup/orchestra-bio) | **HQ unclear / stubs** — gap, not a city claim | linked IDs |

### Coverage gaps

- Flagship-class creation companies named in the [playbook](/2026-boston-vc-2026-biotech-dominance-playbook) without matching `/startup/` pages here
- Classic Boston B2B SaaS / cyber under-indexed vs biotech
- Thin investor graphs on some local names (e.g. Anagram)
