Deer Management Co. LLC dba Bessemer Venture Partners was the subject of a data breach notification filed with the IN Attorney General. The AG filing was recorded on September 30, 2026. The breach or discovery date reported in the filing is August 3, 2026.
From the AG filing description
Operating at the bleeding edge of global technology investment, Deer Management Co. LLC dba Bessemer Venture Partners serves as a premier venture capital firm that partners with visionary entrepreneurs from seed stage to growth. Because venture capital investments require extensive financial commitments, multi-layered corporate restructuring, complex equity distributions, and rigorous due diligence, Bessemer Venture Partners routinely collects and processes vast amounts of highly sensitive information. This encompasses confidential investor profiles, executive compensation packages, proprietary cap tables, banking details, tax identification documents, and sensitive Personally Identifiable Information (PII) belonging to founders, partners, portfolio company executives, and internal personnel. The firm functions as a central repository for high-stakes financial and corporate data, making its digital architecture an attractive target for malicious actors seeking illicit financial gain or strategic corporate intelligence. In 2026, Deer Management Co. LLC dba Bessemer Venture Partners reported a significant security incident to the Indiana Attorney General, highlighting vulnerabilities within its data security environment. While specific forensic details continue to emerge, incidents impacting elite venture capital and investment firms typically involve sophisticated external network intrusions, unauthorized access to internal databases, credential harvesting campaigns targeting high-level executives, or vulnerabilities within third-party vendor ecosystems. In the financial and investment sector, threat actors frequently deploy advanced malware or ransomware to infiltrate networks, exfiltrate confidential enterprise records, and hold proprietary financial systems hostage, leaving firms vulnerable to both operational disruption and severe data exposure. The breach exposed a wealth of sensitive information, creating immediate and severe risks for the affected individuals whose data was compromised. Exposed records likely include full names, Social Security numbers, dates of birth, banking and direct deposit information, tax documents, and high-value corporate investment records. The compromise of Social Security numbers and financial account details exposes victims to an elevated risk of identity theft, unauthorized credit applications, tax fraud, and financial account takeover. For executives, founders, and high-net-worth investors, the exposure of private financial histories and compensation details also creates acute vulnerabilities to targeted phishing schemes, executive impersonation, and ongoing financial extortion. As a custodian of sensitive non-public personal information, Deer Management Co. LLC dba Bessemer Venture Partners was legally obligated to implement and maintain robust administrative, technical, and physical safeguards to protect this data from unauthorized access or exfiltration. Under applicable state data protection statutes, the Federal Trade Commission Act, and industry-standard security frameworks, the firm had a duty to maintain adequate encryption standards, deploy continuous network monitoring, enforce multi-factor authentication, and regularly audit vendor security protocols. The occurrence of a data breach of this magnitude serves as strong evidence of a potential failure to satisfy these foundational legal obligations, suggesting actionable negligence in failing to secure sensitive corporate and personal data. Receiving a data action notification letter from Deer Management Co. LLC dba Bessemer Venture Partners is an official acknowledgment that your private information was compromised due to inadequate security measures. Legally, this notification establishes your standing to participate in a class action lawsuit aimed at holding the company accountable for its security failures. Affected individuals do not need to prove that they have already suffered actual financial loss or identity theft to seek legal redress; the increased risk of future harm is sufficient. Our law firm investigates data breach cases on a strict contingency fee basis, meaning you pay nothing out of pocket and owe no legal fees unless we successfully recover compensation on your behalf.
Based on the data types reported in this filing:
Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.

Common categories of compensation in data breach class actions
Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.
Professional credit monitoring services cost $10–$40 per month. Identity theft restoration services, if needed, can cost hundreds of hours and thousands of dollars. Courts have awarded these costs as direct damages in SSN breach cases.
Direct financial losses resulting from the breach — unauthorized charges, fraudulent transfers, or fees incurred through fraud — are recoverable as compensatory damages. Banks may reverse some charges; a class action recovers the remainder and associated costs.
Several state data breach laws provide for statutory minimum damages — fixed amounts recoverable per affected individual regardless of actual loss. These provisions exist specifically to make legal action viable for victims who have not yet experienced direct harm.
Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.
Applicable State Law
This breach was reported under the Indiana data breach notification law, which mandates notification and establishes your right to seek damages.
No. Under Indiana data breach notification law and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
Banks may reverse fraudulent charges, but they are not obligated to compensate you for time lost, stress, or indirect damages. A class action claim against the breached company can recover those additional categories of harm.
State statutes of limitations for data breach claims typically run 2–4 years from the date of the breach or its discovery. Because this breach was recently disclosed, the window is open — but acting early preserves your options and strengthens the case.
Accepting free credit monitoring from Deer Management Co. LLC dba Bessemer Venture Partners does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Deer Management Co. LLC dba Bessemer Venture Partners during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
