Bitsight paid $115M for Cybersixgill to see breaches brewing in the dark web

Bitsight is a Boston-based cybersecurity startup that rates and manages companies' cyber risk; Cybersixgill analyzed dark-web activity for early signs of data leaks.

That owning dark-web threat intelligence — invite-only groups, code repos, paste sites — makes Bitsight's breach-risk ratings predictive, not descriptive.

Cybersixgill had raised just under $56M (PitchBook) from investors including CrowdStrike, OurCrowd and Terra Venture, at a last valuation of just over $162M in 2022.

Bitsight, last valued at $2.4B when Moody's invested and became its largest shareholder in 2021, works with enterprises to assess their risk profiles — not just their attack surface but the products they use to defend it. Cybersixgill, based in Israel and originally launched as Sixgill, proactively looks for data leaks and indicators of potential breaches in dark-web activity.

On November 14, 2024, Bitsight announced it was acquiring Cybersixgill for $115 million. The price sat below the $162M valuation Cybersixgill reached in 2022 during cybersecurity's white-hot funding market — 'rising tides do not lift all paper boats', as TechCrunch put it. Both companies leaned heavily on AI, and Bitsight said it would bring on both the tech and the team.

Bitsight completed the $115M acquisition, with CEO Steve Harvey committing to keep investing in Cybersixgill's products and continue driving innovation for customers.

It is a startup-on-startup acquisition with the strategic logic spelled out: dark-web intel makes Bitsight's breach-risk ratings forward-looking.

The pricing is documented on both sides: $115M cash against a $162M peak valuation and $56M raised — a down round exit in a cooled market.

It extends the Moody's-era playbook of Bitsight assembling a risk platform rather than building every sensor itself.

Consolidation in a hot sector prices paper valuations against strategic value: a $162M-valued startup sold for $115M when the buyer wanted the capability more than the paint job.

As of 2024-11-14 the acquisition brought Cybersixgill's dark-web monitoring into Bitsight's platform, with both the team and technology joining and continued product investment promised.
