IOSG Ventures portfolio: 54 companies on NAUT, 46 with a token

By NAUT Research · · 9 min read

54 IOSG Ventures portfolio companies tracked on NAUT, 46 with a token, June 2020 to October 2026. Logos: Monad, Babylon, Morpho, Scroll Network, Starknet / Starkware, Boba Network, Mask Network, Taiko, SHRAPNEL, Aztec Network, Synthetix, 1inch.

NAUT tracks 54 companies backed by IOSG Ventures, on 63 round records announced between June 2020 and October 2026, read from NAUT's database on 14 November 2026. Across that IOSG Ventures portfolio, 46 of the 54 carry a token flag on NAUT, and the median round the fund joined was $7.0M across the 61 records that state a size.

Data note. Counted on 14 November 2026 from NAUT's own database. NAUT holds IOSG Ventures under 1 investor row, with 65 round records naming it as a backer. 2 of those records attach to rows NAUT types as investors, so they are left out, which leaves 63 records on 54 live project or platform rows (none archived, none merged). 1 of the 54, a payments company whose round was added on 26 October 2026 with no size, has no public NAUT page yet, so it counts here but sits in no table below.

7 of the 63 records carry no date, and 5 of those repeat the amount of a dated record for the same company (BOB, Brevis, Renzo Protocol, Aztec Network and Babylon), so they may be 1 round stored twice. They stay in the round counts and in the average, and each company is counted once. A round size is the whole round, never IOSG's own cheque. Each company sits in 1 group, chosen from what its own NAUT description says it builds, because many rows carry 3 to 6 sector tags. Written by NAUT Research.

What is in the IOSG Ventures portfolio on NAUT?

The IOSG Ventures portfolio on NAUT leans on the base of the stack: 23 of the 53 listed companies build a chain, a rollup or the data and interoperability layer under one.

Group Firms Tokens Largest round
Base layers 10 10 $225.0M,
Infrastructure 13 13 $70.0M,
DeFi 10 6 $50.0M,
Trading 9 8 $14.0M,
Gaming, social, AI 8 7 $42.0M,
Wallets 3 2 $11.2M,

The firm's own site says it has invested in more than 150 companies since 2017, so the 54 here are the part of that record with a funding round on file at NAUT. The 8 without a token flag are Burrow, Superfluid, Bribe Protocol, Impossible Finance, DODO, MixMob, InsurAce and the company with no page yet. A missing flag is NAUT's record, so open the company page before you treat any of them as pre-token.

How big is a round in the IOSG Ventures portfolio?

Across the 61 records with a size, the average round is $16.5M and the median $7.0M, from $0.7M (Push Protocol) to $225.0M (Monad). Half of the rounds IOSG joined were $7.0M or smaller, so the average is pulled up by a handful of large raises.

Largest round with IOSG per company, the 10 largest on NAUT's record
  1. Monad$225.0M
  2. Babylon$70.0M
  3. Morpho$50.0M
  4. Scroll Network$50.0M
  5. Starknet / Starkware$50.0M
  6. Boba Network$45.0M
  7. Mask Network$42.0M
  8. Taiko$22.0M
  9. SHRAPNEL$20.0M
  10. Aztec Network$17.0M

The chart takes the largest IOSG round per company, so Babylon shows its $70.0M record and leaves out its $18.0M Series A. By year, NAUT dates 6 of the 63 records to 2020, 21 to 2021, 12 to 2022, 6 to 2023, 9 to 2024, 1 to 2025 and 1 to 2026, with 7 undated.

Which IOSG Ventures investments did a source check confirm?

10 of the 54 companies had IOSG's place in the round checked against an outside source for this page. For 7 of them the checker found a page naming IOSG and NAUT matched the quote on it. For Scroll Network the checker reported a March 2023 report from The Block naming IOSG in the $50M round, but that page did not load for NAUT's quote match, so this article leaves it unmatched. For the last 2 no source naming IOSG in the round was found. Those 3, and the 44 companies the check never read, rest on NAUT's record.

Company NAUT record Check found
$225.0M, Apr 2024 's own post on the $225M round names among the investors

$2.8M seed, Aug 2020 's own post names IOSG in its first funding round
$50.0M Series B, Mar 2023 The checker reported The Block's March 2023 report naming IOSG; the page did not load for NAUT's quote match
$12.0M private, Jun 2020 No page found naming an IOSG round with a date or amount
$7.0M strategic, no date No primary source found naming IOSG in the round

The Synthetix row matters for anyone asking whether IOSG leads: NAUT flags IOSG as lead on none of the 63 records, yet that report names it among the 3 firms that led. Treat the missing lead flag as a gap in NAUT's data.

Which companies did IOSG Ventures back more than once?

4 companies show IOSG in 2 rounds with different dates or sizes on NAUT's record:

  • BOB: a $10.0M seed round in March 2024, then a $9.5M strategic round in August 2025.
  • Babylon: the $18.0M Series A in December 2023, then a $70.0M round in May 2024.
  • Zenlink Network: a $1.1M seed round in September 2020, then a Series A with no size stored in September 2021.
  • Play Network (prev. READYgg): a $3.0M private round in May 2022 and a $3.9M seed round with no date stored.

Morpho is a fifth by The Block's June 2026 report, though NAUT holds only its 2024 record with IOSG so far.

What the IOSG Ventures portfolio tells a BD team or a founder

  • Size the pitch to the median. Half of these rounds were $7.0M or smaller, so a seed or Series A team is the typical IOSG company.
  • 46 of 54 have a token flag. Most of this crypto VC portfolio already trades, so token services (market making, listings, liquidity) fit more of it than pre-launch work does.
  • NAUT's record thins after 2024. Only 2 records are dated 2025 or 2026, while The Block reports IOSG in Morpho's June 2026 round, so check IOSG's NAUT page and its own site for newer deals.
  • Co-investors are a warm path. SevenX Ventures and Coinbase Ventures each share 9 companies with IOSG, so a founder already backed by either has a known name to cite.
  • Reach the fund on X. IOSG's handle is @IOSGVC, confirmed against the firm's own domain.
