About this program
Weights & Biases is the default tool for teams doing real model development: experiment tracking, hyperparameter sweeps, model registry, and (increasingly) LLM evaluation and production monitoring through Weave. For AI-native startups that are either training or fine-tuning models themselves, or running an LLM application serious enough to need evaluation infrastructure, W&B is usually the first paid tool the engineering team puts its weight behind.
The startup program layers platform credits on top of W&B's free personal plan. For small research teams the free tier is already enough to run experiments and share runs; the program becomes meaningful once you need team-level workspaces, larger run and storage allowances, and paid access to Weave's LLM evaluation surface. The two products reflect the two working modes of most AI teams today: W&B Models for the training side, W&B Weave for the application side, and a shared workspace where the two connect.
Eligibility and program terms are routed through accelerator, incubator, and VC partnerships. The partner roster and credit allocations shift periodically, so check the current startup program page for authoritative details before assuming a specific bundle.

Frequently asked questions
What does Weights & Biases actually do?
W&B runs two related products. W&B Models handles classical ML experiment tracking, hyperparameter sweeps, and model registry for teams training or fine-tuning models. W&B Weave focuses on LLM application development, covering evaluation, tracing, and online monitoring. Most AI-native startups end up using both.
Is the free tier enough?
For solo founders and small research teams, the free personal plan is often enough to get through early experimentation. The startup program becomes meaningful once you need team workspaces, higher storage and run limits, or paid-tier features in Weave.
Does the startup program include Weave?
Weave coverage depends on the partner track. Some accelerator-backed bundles include credits across both Models and Weave; others are scoped to one surface. Confirm the current product mix with your partner or on the startup program page.
Can I self-host W&B?
W&B offers dedicated and on-premise deployments for teams that need data residency, air-gapped environments, or regulated-industry controls. These are typically priced separately from the hosted startup program, so if you need on-prem, speak to W&B directly.
Which partners offer the W&B startup program?
Partnerships run through accelerators, incubators, and VC funds in the AI space. The specific partner roster rotates. If your investor or accelerator is not listed, you can still apply directly, though partner-backed teams typically qualify for larger credit allocations.
