Data Quality

Data: Low

Sandstone is effectively a black box — no public revenue, no disclosed funding, no verifiable product or customer data exists as of April 2026, making any equity valuation deeply speculative.

Last updated: April 3, 2026

Bull (12%)+150%

Sandstone finds a differentiated niche in an underserved AI vertical (e.g., construction, geology, materials science — implied by the brand), attracts Series B/C funding at a significant step-up, and positions itself for acquisition by a strategic acquirer at 8-12x revenue; employees joining early enough with low strike prices could see 2-3x on paper, though preference stacks from future rounds will dilute common.

Base (48%)-30%

Sandstone remains an early/stealth AI startup competing in a crowded market dominated by OpenAI, Google, Microsoft, and well-funded vertical AI players; it raises a Series A or B at a flat or modest step-up, grows slowly without clear product-market fit, and common stockholders see minimal returns given liquidation preferences from future funding rounds.

Bear (40%)-90%

With no public footprint, no verifiable revenue, and no clear moat, Sandstone fails to differentiate from incumbent AI platforms or larger vertical AI startups, burns through capital, and either shuts down or is acqui-hired at a distressed valuation that returns nothing to common stockholders — options expire worthless and RSUs deliver zero.

Est. time to liquidity~5.0 years

Preference Stack Risk

high

Funding amount and valuation are unknown; as an early-stage company, every future preferred round (likely 3-5 more) will add liquidation preferences ahead of common stock, and if the company raises $20-50M+ before exit, employees could receive nothing in a flat or down exit.

Dilution Risk

high

Early-stage AI companies typically require 4-6 rounds of financing, with each round diluting existing common stockholders by 15-25%, meaning today's equity grant could be worth 30-50% less in percentage terms by the time of any liquidity event.

Secondary Liquidity

none

No secondary market activity is available for an early-stage stealth company; employees should expect no liquidity for 5+ years and must be prepared for equity to expire worthless.

Questions to Ask at the Interview

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

  • 1

    “Given that OpenAI, Google, and Anthropic are all offering increasingly capable foundation models at near-zero cost, what specific proprietary capability or data asset does Sandstone have that prevents customers from switching to a hyperscaler solution in 12-18 months?”

  • 2

    “What is the current ARR or revenue run rate, and what does the path to $10M ARR look like — who are the first 10 customers and what does the sales cycle look like?”

  • 3

    “What is the current cap table structure — how much has been raised, at what valuation, and how many additional funding rounds does the team anticipate before a liquidity event?”
