Ashr
Ashr is a two-founder YC W26 startup building multimodal testing tools for AI agents.
Ashr is a pre-seed pair chasing a niche inside a market that Braintrust and OpenAI are already covering with far more money and shipped features.
Ashr is a startup that helps companies test AI agents before they go live, using AI to create fake user journeys and then grade how the agent performed. The problem is that Braintrust (a much larger, well-funded company) and OpenAI (which bought a competitor called promptfoo) are already in this space and can copy what Ashr does fairly easily, since there's no secret ingredient, no lock-in with customers, and the core technology is just different AI tools glued together. The one thing that matters: if Braintrust or other big players release their own multimodal agent testing in the next 6 months, Ashr's main selling point goes from special to ordinary, and the startup's window to grow closes fast.
Ashr announces named paying customers or a funding round by late 2026. Would show it can gain footing despite well-funded incumbents.
OpenAI expands in-house eval tooling from the promptfoo acquisition. Would show frontier labs absorbing the evals layer Ashr operates in.
- Braintrust: $800M Series B valuation
- OpenAI paid ~$86M for promptfoo
- LangSmith Plus tier: $39/seat/month
- No disclosed paying customers, revenue, or named logos as of mid-2026.
- Core multimodal-testing differentiation could be commoditized by Braintrust Loop or OpenAI-owned promptfoo.
- No proprietary data moat, integrations, or liability/compliance edge identified.
- Unresolved conflicting bio describing company as scheduling/timesheet platform.
- No priced funding round beyond YC investment disclosed as of July 2026.
| Rival | Direction | Evidence |
|---|---|---|
| Braintrust | losing to | Shipped Loop auto-eval feature and raised ~$800M Series B by Feb 2026 |
| OpenAI (promptfoo) | losing to | OpenAI acquired eval tool promptfoo, announced around March 9, 2026 |
| LangSmith | contesting | Zero-config eval tool tied to LangChain ecosystem, priced at $39/seat/month as of May 2026 |
| Armature | contesting | YC-backed Agent Experience tooling overlapping Ashr's automated-testing pitch |
| HUD | contesting | YC W25 peer building agentic evals for computer-use agents, ~15 employees mid-2026 |
| Fabraix | contesting | YC-backed adversarial red-teaming agent for customer-facing AI, adjacent focus |
- Is Ashr profitable in 2026?
- No. Ashr is a pre-seed YC W26 startup that publicly launched on February 27, 2026, with no disclosed revenue, customers, or funding round beyond YC's standard investment. There is no public evidence of any revenue at all, so profitability is not applicable at this stage.
- Could AI replace Ashr's testing platform?
- Possibly. Ashr's own product is AI-generated tests and AI-based scoring, the same territory frontier labs are absorbing: OpenAI acquired eval-tool promptfoo around March 9, 2026, and Braintrust shipped its own auto-generating 'Loop' feature by mid-2026, both threatening to commoditize Ashr's core pitch.
- Who is Ashr's biggest competitor?
- Braintrust is the biggest named threat: it raised a Series B at roughly an 800 million dollar valuation in February 2026, counts Notion, Replit, Cloudflare, Ramp and Dropbox as customers, and already shipped a Loop feature that auto-generates prompts, scorers and datasets, overlapping Ashr's pitch.
- Has Ashr raised a seed round?
- No priced seed or pre-seed round, lead investor, or valuation has been disclosed for Ashr as of July 26, 2026. The only confirmed funding is Y Combinator's implicit batch investment tied to its Winter 2026 cohort membership.
- What does Ashr actually build?
- Ashr builds an SDK-integrated testing and evaluation platform for AI agents that generates synthetic multimodal user journeys, voice, text, image, file and website generation, to catch failures before production, using custom business-goal-aligned scorers, per its Launch YC post dated February 27, 2026.
- Who owns Ashr?
- Ashr is privately held and founder-owned by Shreyas Kaps and Rohan Kulkarni, both ex-Berkeley students, backed by Y Combinator as part of its Winter 2026 batch. No outside investor, parent company, or acquisition history has been disclosed.
