Postman
Postman is a platform where developers build, test, and share APIs.
On the record
Checkpoint: Enterprise renewal cycle following the March 2026 pricing overhaul
The call
Postman still leads API tooling by sheer scale, but a pricing backlash and AI-native IDEs are testing whether that lead survives 2026 renewals.
Postman helps developers test and debug web APIs. It has 40 million users and works with 98% of Fortune 500 companies, which is hard to replace because so many teams already use it together. But the company is in trouble: it removed free teamwork features in 2026, pushing people to cheaper tools like Apidog and Bruno, while new AI coding assistants like Cursor and Copilot are stealing the work Postman does. The one thing that could save Postman is if its new AI features and enterprise tools catch on fast enough to keep big companies paying before too many small teams jump ship to free competitors.
Why
01
AI pressure: Cursor, GitHub Copilot, Google Antigravity IDE. AI-native IDEs now test and debug APIs inside the coding session, pulling that work away from Postman's own tools. Could AI do the core job? Only partly.
02
Bigger players: Microsoft/GitHub, Google, Kong (owns Insomnia). Microsoft could fold free API testing into Copilot Enterprise, and Kong can bundle Insomnia with its gateway product. Could a giant copy it? Yes, easily.
03
What protects it. A base of 40 million developers, 500,000 organizations, and 98% of the Fortune 500 makes switching costly for big teams.
What would change this call
Postman enterprise net retention rate for 2026 renewals reported at or below 120%. Would show Fortune 500 accounts shrinking usage post pricing change, not just SMB churn.
Microsoft bundles free API testing/collaboration into GitHub Copilot Enterprise. Would show IDE-native tools absorbing Postman's core workflow for free.
Postman MCP/Agent Mode regular usage share rises materially above the reported 10%. Would show the AI-agent pivot converting into real paid adoption, offsetting pricing backlash.

Key numbers
- 40M+ developers, 500K+ orgs use Postman
- Secondary trades valued it at $3.4-3.9B, down from $5.6B
- Only 10% of developers are regular MCP users vs 70% aware
Named risks
- March 2026 pricing overhaul removing free multi-seat collaboration triggering SMB and prosumer churn to free rivals.
- AI-native IDEs and coding assistants absorbing API testing and debugging workflows without needing a standalone client.
- No primary funding round or IPO since 2021 while secondary trades already show 30-40% valuation discount as of August 2024.
- MCP/Agent Mode adoption remains at only 10% regular usage versus 70% awareness as of May 2026, leaving AI pivot unproven.
- Conflicting revenue and headcount estimates across sources make Postman's true financial and organizational scale difficult to verify.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Apidog | losing to | Gained visible marketing traction after Postman's March 1, 2026 pricing overhaul removed free team collaboration |
| Bruno | losing to | Cited as free open-source alternative benefiting from March 2026 pricing backlash |
| Insomnia (Kong) | contesting | Kong-owned rival positioned to bundle with gateway offerings amid Postman pricing changes, 2026 |
| Google Antigravity IDE | contesting | Postman integrated its MCP server into Antigravity in April 2026, a partnership that also signals IDE-native competition |
| Microsoft/GitHub Copilot | gaining on | AI coding assistants absorbing routine API testing and debugging workflows historically core to Postman's client |
Questions people ask
- Is Postman profitable in 2026?
- Postman has not disclosed profitability. Third-party estimates (Latka) put 2024 revenue near $313M and investor sources near $120-150M ARR in 2024, but no public profit figures exist as of mid-2026; the company remains private with no IPO filed.
- Could AI replace Postman?
- Postman's own 2025 State of API report found 89% of developers use AI tools daily, but only 10% regularly use MCP versus 70% aware, as of May 2026. AI IDEs are absorbing basic API testing, but Postman's 100,000+ API catalog and enterprise lock-in remain harder to replicate.
- Who owns Postman?
- Postman is privately held and venture-backed, with no parent company, per ZoomInfo as of June 26, 2026. Its last primary round was a $225M Series D in August 2021 led by Insight Partners at a $5.6B valuation.
- Is Postman losing customers to competitors in 2026?
- Yes, visibly. Postman's March 1, 2026 pricing overhaul removed free multi-user team collaboration, triggering community backlash and competitor marketing pushing users toward Apidog, Bruno, and Insomnia, per Apidog's March 16, 2026 blog post.
- What is Postman's current valuation?
- Postman's last confirmed valuation was $5.6B at its August 2021 Series D, but secondary-market trades in August 2024 priced shares at a 30-40% discount, implying roughly $3.4-3.9B, per Economic Times reporting dated August 5, 2024.
- How is Postman responding to AI coding assistants like Cursor and Copilot?
- Postman launched Agent Mode and expanded MCP support at POST/CON 25 in June 2025, letting users convert its 100,000+ networked APIs into MCP servers, and integrated natively with Google's Antigravity IDE in April 2026, betting on becoming the API layer for AI agents.
