Is StableBrowse profitable in 2026?

No. As of July 21, 2026, StableBrowse had no public API or developer documentation and no disclosed revenue, per apis.io. The company is pre-revenue, three-founder, YC-backed startup still finding its business model between browser-agent tooling and training-data supply.

Could OpenAI or Anthropic replace StableBrowse?

Very plausibly. OpenAI shipped its Frontier enterprise agent platform with persistent memory on July 22, 2026, and Anthropic's Computer Use already underlies much of the browser-agent tooling ecosystem, directly overlapping StableBrowse's core pitch to the same frontier labs.

Who founded StableBrowse?

StableBrowse was founded by Deepit Shah, Somansh Shah, and Jay Mehta, all ex-Amazon, per Y Combinator's company profile. The company launched publicly through YC's Spring 2026 batch on May 26, 2026, framed as a browser layer for AI agents.

Who is StableBrowse's biggest competitor?

Browserbase is the established leader in browser infrastructure for AI agents and is cited as the category incumbent across multiple 2026 comparison articles. StableBrowse also faces direct feature overlap from OpenAI's Frontier platform, launched July 22, 2026, and Anthropic's Computer Use capability.

Is StableBrowse pivoting its business model?

Yes. At its May 26, 2026 YC launch StableBrowse framed itself as a browser layer for AI agents; by July 21, 2026 its homepage messaging shifted to positioning itself as a training-data supplier for frontier labs, per apis.io's provider profile.

Has StableBrowse raised a funding round?

No primary-source funding announcement (press release or founder statement) was found as of July 2026. A CB Insights aggregator page cites early-stage figures, but no independently confirmed round has been reported by StableBrowse or investors directly.

YC Spring 2026 · United States

StableBrowse

Early-stage startup selling browser automation tools and training data to AI labs.

Not much stands between this business and its pressures.

On the recordSince 27 July 2026 · Checkable from January 2027 · Every call on the record Checkpoint: Six-month window to close a funding round or show named paying customers

The call

A three-person, pre-revenue team pitching browser and data tools to the same labs that can build the same tools themselves.

StableBrowse sells software that helps AI agents browse the web and collect training data, but it sells to the exact companies (like OpenAI and Anthropic) that are most likely to just build this themselves instead of paying for it. There is nothing stopping these companies from copying StableBrowse's work or absorbing it into their own products, and in fact OpenAI and Anthropic have already shipped their own versions. The one thing that could change this picture is if StableBrowse can lock in real paying customers (either big companies or AI labs) and launch a public product before these giants improve their own tools so much that nobody needs StableBrowse anymore.

Why

AI pressure: OpenAI Frontier and Anthropic Computer Use. Both labs now ship persistent-memory agent browsing in-house, the exact function StableBrowse sells them. Could AI do the core job? Yes, likely.

Bigger players: Browserbase. Browserbase already runs 1000+ customers and 50M sessions in the same browser-agent space, with a live Series B behind it. Could a giant copy it? Yes, easily.

What protects it. None visible yet: no signed customers, no public API, no exclusive data as of July 2026.

What would change this call

StableBrowse closes a seed/Series A round with named customers within 6 months. Would show real commercial traction beyond pre-revenue status.
StableBrowse publishes a public API and developer documentation. Would indicate product maturity and external adoption capability.
StableBrowse announces enterprise customers in regulated verticals (insurance, banking, healthcare, legal). Would show a pivot away from frontier labs as buyer toward defensible workflow lock-in.

Key numbers

$500K raised across two rounds (Apr 1 2026)
$0 reported revenue (Mar 31 2026)
No public API or developer docs live (Jul 21 2026)

Named risks

No public API or developer documentation reported as of Jul 21, 2026. Severity: high
Sells to frontier labs that are also best positioned to build the same capability in-house. Severity: high
Repositioning from browser-agent framing to training-data framing suggests unresolved product-market fit. Severity: medium
Very small team and early funding stage limit ability to compete with scaled rivals like Browserbase. Severity: medium
