AI Agent Startup Instinct in Talks for $1 Billion Funding at $10 Billion Valuation

Instinct, the personal AI assistant operated by Spear Street Technology, is in talks to raise $1 billion in funding at a valuation of about $10 billion, with Sequoia Capital and Benchmark expected to lead the round. The company previously completed a $250 million funding round in August at a $2.25 billion valuation. Its user base has surpassed 100,000, and the service occasionally experiences response delays due to compute constraints.

Funding Background and Technical Constraints

Instinct is invite-only, and users give it task instructions via text message or phone call, including replying to messages, booking restaurants, negotiating bills, and responding to emails. The system executes tasks by simulating the way humans operate phones and computers, but as its user count surpassed 100,000, its compute capacity has reached its limit, and some users received a notice that "responses may be slower." CEO Noah Shinn previously said the company is not considering charging users for now, hinting that it may explore advertising or other revenue models.

This funding negotiation comes as Instinct's user activity is rising. The $250 million financing completed the previous month lifted the valuation from $2.25 billion to $10 billion, reflecting strong investor demand for consumer AI agents.

Comparison with Meta Muse

Meta launched the free AI assistant Muse on September 8, with features similar to Instinct, including task execution and conversational interaction. Instinct is currently still in invite-only testing, while Muse is already open to the public. Both products rely on large-model-driven task planning and tool-calling capabilities, but Instinct emphasizes zero-learning-cost operation through a text-message interface.

Specific use cases Instinct has demonstrated include planning cross-country road trips, buying weekly groceries, purchasing concert tickets, canceling hundreds of dollars in subscription services, and preparing for a wedding. These cases show its ability to execute multi-step task chains, but public information does not disclose specific success rates or average task completion times.

Impact on Developers and Enterprises

For developers, Instinct's text-message interface lowers the barrier to entry, but limited by the invite-only system and compute quotas, the room for third-party integration testing is limited. If enterprise users want to embed similar agents into internal processes, they need to assess compute costs and privacy compliance risks themselves, because Instinct has not yet announced an enterprise-grade API or data processing policy.

The impact on existing technology stacks is reflected in the task execution chain: traditional RPA tools rely on fixed scripts, while Instinct dynamically calls device interfaces through natural language instructions. This approach reduces the maintenance cost of predefined rules, but increases dependence on model inference stability.

Competitive Landscape and Points to Watch

If this funding round is completed, it will make Instinct one of the highest-valued companies in the AI agent sector. In an August 26 social platform post, Noah Shinn mentioned that early user feedback has been positive, but did not provide revenue or retention data.

From a business logic perspective, the invite-only system helps control early compute consumption, but it also limits large-scale testing. After Meta launched free Muse, if Instinct maintains a paid or advertising model, it will need to find a balance between user experience and cost recovery.

CEO Noah Shinn said on social media: "I'm excited about everything early users are doing with Instinct. They've told me they've planned cross-country road trips, bought weekly groceries and concert tickets, and canceled hundreds of dollars in subscriptions. Some have even used it to prepare for a wedding."
