Unexpected ₹147K Claude charges despite active Microsoft for Startups sponsorship
Hi Microsoft for Startups team and community, I am a Microsoft for Startups participant using an Azure Sponsorship subscription. I recently discovered unexpected charges from Anthropic Claude through Microsoft Foundry. The Claude usage was billed as Marketplace/SaaS charges instead of being deducted from my Microsoft for Startups Azure sponsorship credits. My Azure Sponsorship credit is still active and has a substantial unused balance. However, my Azure Cost Analysis currently shows approximately ₹491K in September charges, with approximately ₹475K categorized as SaaS, primarily related to Claude. I currently have an invoice amount of approximately ₹147K due. I stopped the Claude deployments as soon as I discovered the charges to prevent further usage. I contacted Azure Billing Support multiple times, but the requests were closed with a message saying that the issue falls outside Billing and Subscription Support because it involves Marketplace/third-party services. I was directed to Marketplace refund resources instead. I also tried to contact Microsoft for Startups support. I was previously instructed by the Microsoft for Startups team to use the Founders Hub support portal, but my account now redirects to the newer Microsoft for Startups experience in Azure, where I cannot find the documented startup program support option. I need help getting this escalated to the appropriate Microsoft for Startups or Marketplace team for an actual review. Specifically, I would like to know: What is the correct support channel for this situation? Can Microsoft review the unexpected Claude charges? Is a discretionary credit, refund, or billing adjustment possible given the circumstances? I can provide screenshots showing my active sponsorship, remaining Azure credits, Claude charges, and invoice privately if required. Thank you.
How can a Microsoft for Startups user escalate unexpected Claude Marketplace billing?
I have approximately ₹9.49 lakh of Microsoft for Startups Azure credits remaining. I deployed Anthropic Claude through Microsoft Foundry and later received invoice G183537293 for ₹70,716.76 because the Claude Marketplace usage was not covered by the sponsorship credits. I understand the eligibility rule now. My question is about escalation. Azure Billing has told me Marketplace adjustments are handled by the publisher. Anthropic has told me Azure Marketplace billing is processed through Microsoft. I have therefore been redirected between both parties. I also found a previous Microsoft for Startups case involving similar unintended Claude/Foundry usage where the customer reported receiving a $1,000 special-exception credit: https://learn.microsoft.com/en-us/answers/questions/5728641/azure-ai-foundry-presents-third-party-ai-models-as?utm_source=chatgpt.com Is there a Microsoft for Startups, Marketplace billing, or Foundry escalation team authorized to review a one-time goodwill credit in this situation? I am specifically looking for the correct escalation path, not asking the Q&A community to access or modify my invoice.
Startup verification failed for newly incorporated company - records now synced, need manual review
Hi team, I need a manual review of my Azure startup credit business verification. The automated check returned "We couldn't verify your startup. We'll switch you to a pay-as-you-go subscription once your remaining Azure credits run out or expire." No reason was given, and there is no option to resubmit. Context: - Company: I entered the legal name exactly as on the Certificate of Incorporation. The company was incorporated in India on 30 Sep 2026. - I submitted the business details on the same day I received the Certificate of Incorporation. Because the company had just been incorporated, its records had not yet reached public databases at that time. - Those records have now synced. The CIN and PAN can both be verified, and the company bank account is being opened. - I'm a genuine early-stage startup. Support history: - Emailed email address removed for privacy reasons on 1 Oct 2026: no response - Azure support ticket 2610030030000809, opened 4 Oct 2026: no response Every listed Microsoft for Startups support link redirects back to the Azure portal, so I can't find another channel. My current credit expires in 30 days, so this is time-sensitive: I need to decide whether to continue building my startup on Azure. Request: please escalate to the startup credits verification team for a manual review. I can share the company details, documents (Certificate of Incorporation, PAN, TAN), subscription ID and any other details privately. Thank you.
Cannot enroll in Founders Hub — portal redirects to Azure home page
Founder of OrbitSub (orbitsub.com). When I sign in to enroll in Microsoft for Startups / Founders Hub, it redirects me to portal.azure.com/#home instead of showing an application form — I can't apply. Tried multiple times, normal + incognito. Please help me enroll or tell me the correct step. Screenshot attached.Azure Startup Credit Issue
Hi, I've been trying to verify my LinkedIn account to unlock $1,000 in Azure startup credits for over a week. Every time the OAuth callback hits error and, I get: {"error":{"code":"BadRequest","message":"BadRequest (Conflict)"}}. I've revoked all LinkedIn app permissions on both LinkedIn and Microsoft sides. I suspect that the issue is an orphaned LinkedIn identity record in your backend from a previous failed attempt. My support ticket has gone unanswered for over a week now and I also created a post in the learn community that went unanswered for days now. Could you point me to the right person? Happy to provide any account details needed.
No Decision After 7 Working Days + Portal Loop Issue – Rain Stella Technology
Hi Microsoft for Startups Community & Team, I am following up on my Microsoft for Startups application submitted on behalf of Rain Stella Technology, and would also like to flag a portal issue I experienced after the application was submitted. --- Application Status --- I received a confirmation email acknowledging receipt of my application, however it has now been 7 working days with no further communication — no approval, no decline, and no request for additional information. According to Microsoft's own guidelines, applications are typically reviewed within 3 business days. We are now more than double that timeframe with no update. Application Details: • Applicant Name: Khalid Adine • Startup Name: Rain Stella Technology • Status: Receipt confirmation received, no decision communicated since • Days Elapsed: 7 working days --- Portal Issue --- During and after submitting my application, I encountered a frustrating portal bug where, instead of displaying a confirmation screen or application status, the portal kept redirecting me back to the "Apply Now" screen — as if my submission had not been recorded. I received the receipt confirmation email, which confirmed the application went through, but the portal still does not reflect any application status. This caused significant confusion, and I wanted to flag it in case it is a widely known issue affecting other applicants. I also attempted to contact support via email (email address removed for privacy reasons), but the address returned a bounce error, leaving the forum and contact form as my only available channels. --- My Requests --- 1. Can someone from the team confirm the current status of our application? 2. Is any additional information or documentation required from our side? 3. Can the portal loop bug be investigated and fixed for other applicants facing the same issue? 4. What is the correct and currently working support email or channel for urgent queries? We are actively building our product and are eager to move forward with the program. Any update would be sincerely appreciated. Thank you for your time and support. Khalid Adine Founder, Rain Stella Technology
Founders Hub billing issue - stuck between Microsoft and ISV with no resolution path
Hi everyone, I'm reaching out to the community because I've hit a wall with standard support channels and hoping someone from the Founders Hub team or other founders who've faced similar issues can help. QUICK SUMMARY I'm a Founders Hub participant who got charged ~€1,000 for using Claude (Anthropic) models through Azure AI Foundry. I assumed these were covered by my $25k Sponsorship credits since: • I used ai.azure.com (not a separate marketplace) • There was no clear warning about separate billing • There's no way to monitor Marketplace spending in Founders Hub THE PROBLEM: I'm stuck in a loop: • Microsoft says "contact the ISV for refund approval" • Anthropic says "billing is handled by Microsoft, not us" • The "Support" link Microsoft points to redirects back to Microsoft Support I've sent detailed emails explaining this circular situation. Support keeps responding with the same copy-paste policy text, ignoring my request for escalation. MY ASK 1. Is there a dedicated support channel for Founders Hub billing issues? 2. Has anyone from the Founders Hub team dealt with similar Marketplace confusion before? 3. Any founders here who successfully resolved unexpected Marketplace charges? I'm not trying to get something for free - I already paid the first invoice (€460). I just want help with the second invoice that surprised me a month later. The Founders Hub program has been great otherwise, but this experience has been really frustrating. Any pointers would be hugely appreciated. Thanks! Bartek
Business Verification failure, no reason?
I've tried repeatedly to verify my business which is failing. My credits are expiring soon so I need urgent help. I have not received a reply from the support ticket in the founder's home. My company is registered in the UK with Company House, it's clearly visible publicly that I am the owner. I've submitted a unified PDF with the Articles of Incorporation, Company Certificate showing it's address and company number, and everything else. These match the exactly details I put in the Founder's Hub. Yet I keep being rejected. I only have 2 appeals left. I do not know what to do when I'm not even told what the rejection reason is? How do I find out why my business verification is being rejected? The box states: "Unfortunately, we are unable to verify the information provided. Please provide documentation (tax invoices, bank statements, business registration certificate, etc.) that displays the registered business name and address to complete the verification process. If the business information was entered incorrectly, you can update the account information and restart the verification process." I have provided exactly this information. What do I do?
