Funding Halved, and the Money Went to Gatekeeping AI Agents

This issue's theme · Gatekeeping for AI Agents

The SVTR AI Venture Activity Index stood at 155.7 this week, down 4.8% from last issue and 55.7% above the 2025 median. Among sectors, Productivity (+8.6%) and PropTech (+6.0%) led gains, while Financial Services fell 5.3%.

This week we tracked 92 confirmed rounds with $3.3B disclosed, less than half of last week, and no single round above $1B. Money was scarcer, yet deals that put gates around AI agents piled up: five companies building security and governance for agents raised $120M combined, and Workday signed to acquire C1.ai, an identity platform for agents.

New this week: person pages now show "Personal investments", the companies someone has backed in their own name; see, for example, Sam Altman's personal investments.

2. Our Take

• Money is going to gates around AI agents. Five companies building security and governance for agents raised $120M combined (Table 3); Workday signed to acquire C1.ai, which manages agent identity, and Freshworks signed to acquire Torii, which manages AI spend. Our view: before a company lets agents into its systems, it has to answer who the agent is, what it may touch, and who pays when something goes wrong, so these companies are likely to win budget earlier than agent applications themselves.

Data: SVTR AI venture database, as of 2026-10-18. The five total $120M.

• Inference compute in the US and China is being paid for different things. Modal's valuation rose 3.4x in five months yet remains under 16 times annualized revenue; in China this week the compute money came mainly from state capital and telecom carriers: Infinigence AI counts six state-backed investors, China Telecom led Qingcheng.AI, and Beijing state fund Yizhuang Guotou led SUNMMIO. Our view: Chinese valuations are a bet on whether domestic chips can be put to work, not on revenue.

• The big chipmakers are backing optical interconnect together. Salience Labs, which makes all-optical switching chips, raised $125M with both AMD's and Intel's investment arms participating; Ayar Labs, in the same field, is the only one of 61 interconnect companies backed by Nvidia, AMD and Intel at once. Our view: no chipmaker wants to bet on the wrong approach, so they co-invest; these valuations buy a neutral position, and payoff waits until one of them puts the chips into a volume rack.

Further reading

• Modal and Infinigence Raised Big the Same Week: The US Prices Compute Middlemen on Revenue, China on Domestic Chips (Signal): the full case for the second point, with valuation multiples and investor makeup on both sides.
• Ayar Labs: NVIDIA, AMD and Intel All Bet on One Optical Interconnect Startup, Valued 3.7x Higher in 15 Months (Profile): the basis for the third point, comparing investors across 61 interconnect companies.
• Compute Financing Has Changed: $9.56 Billion Went Into Convertibles (Feature): compute money is not only growing but changing contract structure; three of the four largest deals were convertibles.
• TypeSafe Valued at $7.5B, at Least a Quarter Below the Rumor (Radar): during its talks, big tech shipped the same product at the same price.
• The Tian Keyu Affair: Why Can China’s Venture Media No Longer Report on Controversy? (Thesis): three venture outlets each told their own version, and none independently reconstructed the key facts in dispute.
