Decagon completes employee tender at $4.5B

The tender shows Decagon had already cleared the key startup test of private market credibility, investors were willing to buy employee shares at the exact same price they had just paid for new primary stock. That matters because a flat tender right after a big round is usually less about resetting price and more about retaining staff, reducing pressure for early exits, and signaling that the Series D valuation was supported by real secondary demand as the company scaled from roughly $10M run rate at the end of 2024 to $100M by July 2026.1 2 3 4

• This was Decagon's first liquidity event for employees, and it covered more than 300 people. In practice, that lets early staff sell part of vested shares without leaving, which is especially important at companies hiring aggressively and competing for AI talent.1
• The timing matters. Decagon raised at $650M in October 2024, $1.5B in June 2025, and $4.5B in January 2026, then held that same price in the March 2026 tender. That sequence suggests investors saw enough traction to support the markup, but not a need for another repricing two months later.1 2
• In AI customer support, private markets were rewarding category leaders very aggressively. Decagon was estimated at $35M annualized revenue in late 2025 and later $100M by July 2026, while Sierra was valued at $4.5B in October 2024 and reached $15.8B by May 2026. A clean secondary at round price helped keep Decagon in that top tier conversation.2 3 5 6

Going forward, more late stage AI application companies are likely to use tenders as a standard compensation tool, not a one off event. For Decagon, that means using private liquidity to hold the team together while pushing toward the next valuation step, with the market increasingly judging it against the biggest AI support platforms rather than ordinary SaaS companies.3 4 5 6
