Data: Low

QuestDB is a technically differentiated but financially precarious Series A from 2021 with $3M ARR sitting far below its $18M total funding stack — employee common stock is currently under water and recovers nothing in any exit at or below today's $9M analyst-estimated valuation.

Last updated: May 14, 2026

Bull (10%)+350%

QuestDB captures emerging AI agent and real-time observability workloads, growing ARR from $3M to $18M+ by 2028 and attracting a strategic acquisition or Series C at 8-10x ARR (~$150M+). After clearing the $18M preference stack and accounting for dilution from a new round, common equity delivers a 4x+ return from the $9M entry valuation.

Base (45%)+50%

Steady enterprise adoption pushes ARR to $8-10M, enabling a $40-60M strategic acquisition that clears the $18M preference stack and returns modest but positive value to common stockholders. After dilution from a bridge or Series B, employees with small grants see limited nominal upside from the $9M valuation baseline.

Bear (45%)-85%

Revenue stagnates against InfluxDB, TimescaleDB, and AWS Timestream while the company exhausts runway without closing a Series B, forcing an acqui-hire or wind-down at below $18M. The full $18M preference stack absorbs all proceeds and employee common equity is entirely wiped out.

Preference Stack Risk

severe

Funding Intensity

200%

Total funding of $18M against a $9M current valuation means liquidation preferences represent 200% of today's company value, leaving common stockholders with zero proceeds in any exit at or below $18M.

Dilution Risk

high

The company almost certainly needs to raise a Series B or bridge to sustain operations, and any new capital raised at or below the 2021 Series A price would trigger anti-dilution provisions for preferred holders, further concentrating losses on common equity.

Secondary Liquidity

none

At a $9M estimated valuation with 30 employees and no Series B, QuestDB has no secondary market activity, no known tender offer program, and no realistic near-term liquidity event outside of a full acquisition.

Questions to Ask at the Interview

Strategic questions based on QuestDB's data — designed to show you've done your homework.

  • 1

    “What is QuestDB's current ARR growth rate year-over-year and net revenue retention, and what specifically is driving the AI Agents product line adoption?”

  • 2

    “What is the company's current monthly burn rate and cash runway, and is the leadership team actively pursuing a Series B, exploring strategic partnerships, or targeting cash-flow breakeven on the current $3M ARR base?”

  • 3

    “Can you walk me through the fully diluted cap table — specifically the liquidation preference structure on the $18M raised (1x non-participating vs. participating with cap), and what percentage of the fully diluted share count my grant would represent?”
