There is no evidence in the available reporting that Bigstring became a major web success, and whether it still operates is unresolved. The “next big thing” description began as speculation about an email service whose proposed controls included message recall and expiration—not as a finding about adoption or commercial scale.
What was Bigstring supposed to do?
In a 2007 opinion article, CIO contributor Chris Moore described features Bigstring’s creators proposed: self-destructing messages, recallable or erasable email, non-forwardable messages, and messages recipients could not print or save. These were attributed product claims, not independently tested results. Moore’s CIO article framed the idea as potentially transformative, asking whether it could change email.
Moore wrote, “It might be the next Facebook or Youtube of e-mail.” That was one contributor’s opinion, not a measured forecast or evidence that Bigstring had achieved broad adoption.
Did Bigstring become a major web success?
The evidence available here does not establish that it did. A 2026 iTechGuides profile characterizes Bigstring as a small historical startup and says its current operations, users, revenue, and growth are unverified. No independently validated audience, usage, revenue, market-share, or growth figures are reported in the sources available for this article.

The profile reports that Bigstring was founded in 2003 and had $2.8 million in total funding, attributing those historical figures to CB Insights. They are database-reported details relayed by a secondary profile, not independently verified financing records or proof of present-day activity. Read the iTechGuides profile.
Is Bigstring still operating?
That remains unknown from the available evidence. It does not establish that a Bigstring service or team exists today, but it also does not provide an authoritative closure notice. Without current first-party evidence, it would be inaccurate to call the company definitively active or closed.

Why the original email idea raised practical questions
Features that let a sender recall, expire, or restrict a message may sound useful when information is sent to the wrong person or needs tighter control. But controlling what happens to a message after delivery can conflict with a recipient’s need to keep evidence. Moore raised concerns about lost records and the implications for corporate auditors, privacy staff, and records executives; his article identified the issues but did not resolve them.
That tension matters to personal and organizational email alike: a sender’s preference to withdraw a message is not the same as ensuring the recipient cannot preserve its contents, nor does a disappearing message necessarily satisfy recordkeeping requirements. The 2007 article does not establish how reliably Bigstring’s proposed features worked or how they handled those responsibilities.

What would justify calling it a breakout today?
A “next big thing” claim needs evidence beyond an appealing feature list or an early prediction. For Bigstring, the relevant questions would be:
- Working product and operator: Is there a verifiable service and an identifiable organization running it?
- Adoption: Are there independently dated user or customer figures?
- Durable use: Is there evidence of revenue, retention, or repeat usage?
- Distinct advantage: Does the product demonstrably solve a problem better than alternatives?
- Organizational fit: Can its controls coexist with audit, privacy, and records obligations?
The reporting cited here supplies no data to answer those questions about Bigstring today. The original concept drew attention, but attention and possibility are not proof of product-market fit or lasting impact.
