Company profile
researched Aug 2026Questbook, a product operated by CreatorOS Inc., provides tooling for grant and bounty programs in the Web3 ecosystem. On the grantee side, the platform lets builders create a profile that is referred to grant managers, browse featured and recently funded grant listings, and receive grant opportunities. On the program side, organizations can launch and administer grant programs through the application.
The product is organized around what the company calls "delegated domain allocation," an approach it describes as pioneered by the Ethereum Foundation, in which a program owner delegates capital allocation decisions in a given domain or region to designated allocators. The company positions the dApp as trustless and composable, stating that data and source code are permissionlessly available so that programs can customize the tool. Press coverage from 2022 described Questbook as screening projects using signals such as a developer's on-chain and GitHub history, and reported that the company had built its own gasless wallet so that users store information on-chain without paying transaction fees.
Questbook also maintains community and content activity alongside the core product, including a builders podcast featuring founders from other Web3 protocols, research content, a Permissionless Work Improvement Proposal process, and a grants pool for improvements to Questbook itself."]
Founding story
TechCrunch reported that the startup was founded in May 2021 and initially set out to help builders earn in crypto. Co-founder Madhavan Malolan said the team found that few developers knew Solidity or Rust, so Questbook began teaching those languages for free and published over 100 tutorials, building an audience of more than 18,000 developers before pivoting toward helping those developers secure funding.
Business model
Questbook supplies grant- and bounty-program software to protocols, DAOs and foundations that distribute capital to developers, and a matching layer that refers builder profiles to grant managers. At the time of the 2022 Series A the company said it did not monetize the software.
TechCrunch reported in May 2022 that Questbook did not then monetize its software; no other revenue model is described in the available sources.
Traction
Site figures cite 60,000+ builders, 7,000+ proposals and more than $10 million paid out. In May 2022, the company reported facilitating over $1.5 million in grant money for partners including Polygon, Aave, Near and Harmony, an 18,000-developer learning community, and a stated plan to scale disbursements to $30-50 million over the following two quarters.
Latest developments
The questbook.app site currently presents a grantee referral flow, grant listings and a path for organizations to start a grant program, reporting 60K+ builders, 7K+ proposals and $10M+ paid out. The questbook.xyz site markets delegated domain allocation tooling for DAOs and foundations and a $100K grants pool for improving Questbook.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
The company states that top Web3 ecosystems including Polygon, Solana, Aave and Celo use Questbook to attract builders. In 2022 it was reported to work with Polygon, Aave, Near and Harmony.
Questbook emphasizes delegated domain allocation for grant programs, a decentralized and composable dApp with open data and source code, automated credentialing of applicants via on-chain and GitHub history, and a gasless wallet that hides blockchain mechanics from grant applicants.
Technology
A decentralized application that the company describes as trustless, with data and source code permissionlessly available and customizable. It applies credentialing signals such as a developer's on-chain and GitHub history to screen applications, and includes an in-house gasless wallet designed for storing information rather than transferring funds, so users incur no transaction fees.
Go-to-market
Direct adoption by Web3 ecosystems and foundations running grant programs, supported by developer-community channels — free coding tutorials, a builders podcast, Discord/Discourse forums, newsletters and a self-funded grants pool for contributors to Questbook.
Two sides: blockchain protocols, foundations and DAOs that operate grant, bounty and small-fund programs; and Web3 developers and builders seeking grants and work opportunities.
Geography
Operated by CreatorOS Inc. Sources do not consistently establish a headquarters; one directory listing associates the company with Palo Alto, California. The platform itself is used by Web3 ecosystems globally, and the company has described enabling local allocators in different regions.
History
After starting as a free Web3 developer education effort in 2021, Questbook moved into grants infrastructure, and by May 2022 was working with Polygon, Aave, Near and Harmony and had facilitated more than $1.5 million in grants. That month it announced an $8.3 million Series A led by Lemniscap. Its later site materials describe the product as delegated domain allocation tooling for DAOs and foundations, and the questbook.app site reports 60K+ builders, 7K+ proposals and over $10M paid out.
Risks & controversies
Sources note ecosystem-level risks rather than company-specific controversies: developer participation in crypto declines during bear cycles, the pool of Web3 developers is small relative to global software engineers, and unscreened grant programs can be abused — TechCrunch cites Uniswap's $20 million no-strings grant, of which over half was reportedly swapped for a stablecoin. Investor Alameda Research is listed among Series A participants. Public directory data on Questbook is inconsistent (differing founding dates, headquarters and funding totals), which limits confidence in secondary sources.
