About Altstock
Altstock brings clarity to one of the least transparent corners of Indian finance: the shares of late-stage private, unlisted and pre-IPO companies. These businesses are widely discussed but thinly documented — prices are quoted informally, financials are scattered across filings, and reliable, comparable information is hard to find. Altstock gathers that information in one place and presents it with a consistent, honest standard for how strongly each number is supported.
What Altstock does
We research and organise public and filed information about private companies so you can understand them before you act on your own. The platform covers:
Business overview, sector, funding rounds, cap-table basis and registered details — drawn from filings and credible sources.
Reported revenue, EBITDA, PAT, balance-sheet and cash-flow lines in ₹ crore, with standard ratios computed from them.
The levels at which interest has been expressed — clearly labelled indicative, non-binding and non-executable.
Upcoming and recent Indian IPOs with DRHP/RHP status, price band and dates from the NSE/BSE public feed.
Filter companies on transparent factor scores and compare them side by side on the same definitions.
A directional read on private-market activity — an indicator, not an investable index or benchmark.
What Altstock is not
This matters, so we state it plainly. Altstock is not a SEBI-registered investment adviser, research analyst, stock broker or portfolio manager, and not registered with RBI or IRDAI. We don’t give advice or recommendations, we don’t solicit investment, and we don’t execute, settle, match or facilitate any trade. Any transaction in unlisted shares is arranged and completed directly between the parties, through their own advisers and intermediaries. Unlisted securities are illiquid and high-risk, and you can lose some or all of the money you put in.
How we treat the numbers
Every figure that matters carries a confidence label — Verified, Reported, Indicative or Estimated — so you always know what stands behind it. We prefer primary filings (MCA/ROC, audited reports, DRHP/RHP, exchange disclosures) over secondary reporting, and we don’t fabricate market depth or financials: when something isn’t on file, we show it as unavailable rather than inventing it. The full rules are set out in our Methodology.
Who it’s for
Altstock is intended for informed, eligible investors and entities who research the private market for themselves — including HNIs, family offices, wealth-management firms and companies. The platform is open to browse; account features such as a watchlist and logging non-binding interest are available after sign-in. Always assess your own situation and consult a SEBI-registered adviser before making any investment.
