Hello Haven Raises $15M Pre-Seed Led by Mayfield for Personal AI Digital Twin

Hello Haven Raises $15M Pre-Seed Led by Mayfield

Hello Haven, a Park City, Utah-based personal AI company, has raised $15 million in Pre-Seed funding. The round was led by Mayfield and announced on September 17, 2026.

Mayfield is the sole investor listed in the round.

What Hello Haven Does

Hello Haven's product, Haven, is a personal AI digital twin. It builds a private memory graph of each user - learning their preferences, relationships and decision patterns - and completes tasks on their behalf.

Haven operates across multiple channels:

• Phone
• Text
• Email
• Voice
• Web
• App

The platform draws on more than 500 AI models and over 100 app integrations, according to the company.

Founding Team

Hello Haven was founded by serial entrepreneur Frank Addante and Duc Chau. Addante's background as a repeat founder is notable at the Pre-Seed stage, where investor conviction often rests heavily on the founding team.

Product Availability

Haven is available at my.hellohaven.ai, on the Apple App Store and on Google Play.

That multi-platform availability at the Pre-Seed stage means the product is already in users' hands rather than in private beta, giving the company a live surface for learning from real usage.

The Memory Graph Angle

The core of Haven's pitch is the private memory graph. Rather than treating each AI interaction as isolated, Haven accumulates a structured model of the user - what they prefer, who they know and how they make decisions - and then acts on that model.

This is a meaningfully different approach from single-purpose assistants. The value of a digital twin compounds as the memory graph deepens, which is why the company emphasizes privacy: the graph is described as private to each user.

Breadth of the Stack

The company cites more than 500 AI models and over 100 app integrations. That breadth suggests Haven is positioned as an orchestration layer rather than a single model wrapper - routing tasks to whichever model or integration fits, while the memory graph provides continuity across them.

Why It Matters

Personal AI is a crowded category, but most products today are assistants that respond to prompts. Hello Haven is betting that the durable advantage lies in persistent, personal context - a memory graph that makes the AI genuinely useful for tasks the user would otherwise handle themselves.

The $15 million Pre-Seed, led by Mayfield, is a substantial first check for a company at this stage. It gives Hello Haven room to develop the memory graph, expand integrations and grow the user base across its existing platforms.

What's Next

Hello Haven has not disclosed specific plans for the new capital. The company's stated foundation - a private memory graph, a broad model and integration layer, and availability across web, iOS and Android - defines the product surface it will build on.

For investors tracking personal AI, Hello Haven is worth watching: a repeat founder, a differentiated memory-centric architecture and a lead investor in Mayfield backing the Pre-Seed.
