Identifying early-stage investors (Pre-Seed and Seed) with a proven thesis or track record in developer tools, APIs, and cloud infrastructure requires looking at micro-VCs and specialized funds that act as "day-one" partners, as well as generalist firms with heavy technical allocations.

Active early-stage investors in this domain include:

Boldstart Ventures : Operating heavily as a day-one, inception-stage investor, they write early checks (Pre-Seed and Seed) specifically tailored for developer-first software, cloud infrastructure, and cybersecurity.
Heavybit : A specialized accelerator and investor program explicitly focused on developer-first and enterprise infrastructure companies, offering specialized go-to-market support for dev tools.
Initialized Capital : An operator-heavy early-stage seed fund that frequently backs infrastructure, foundational dev tools, and technical plumbing from the earliest rounds.
BoxGroup : Known as an active pre-seed and seed investor that regularly participates in developer tooling, APIs, and technical infrastructure rounds alongside larger leads.
Andreessen Horowitz (a16z) : While managing massive multi-stage pools, a16z maintains an aggressive early-check and seed strategy to secure pro-rata rights in infrastructure and developer ecosystem plays.
Unusual Ventures : Focuses heavily on early-stage enterprise infrastructure and developer-focused tech, providing dedicated hands-on platform support for technical founders.

Note on evaluation: According to community VC tracking directories like VC Sheet for Devtools , early-stage evaluation in this sector heavily prioritizes organic technical traction—such as GitHub momentum, Hacker News/X buzz, and architectural community backing—over traditional top-of-funnel marketing metrics.

If you'd like to narrow this down, let me know:

Are you looking for lead investors who write large $1M+ checks or angel/micro-VCs for smaller pre-seed syndicates?
Do you have a specific sub-sector in mind (e.g., AI infrastructure, observability, security, core APIs)?

I can tailor a more targeted list based on your needs.

Investors backing early-stage DevTools and cloud infrastructure startups

Yes. There is a strong group of venture capital firms and individual investors with established track records in developer tools, cloud infrastructure, open-source software, databases, APIs, observability, and enterprise infrastructure.

I would prioritize investors based on three criteria:

Early-stage experience: Evidence of investing at pre-seed, seed, or Series A.
Relevant portfolio: Multiple investments in developer-facing or infrastructure businesses, rather than just general enterprise SaaS.
Technical founder alignment: Experience backing founders building products for software engineers, platform teams, and infrastructure buyers.

Below is a shortlist of particularly relevant investors, with an emphasis on those worth researching for an early-stage fundraising process.

1. Highest-priority venture capital firms

2. Individual investors worth targeting

For fundraising, identifying the actual decision-makers is just as important as identifying the fund.

These are particularly interesting individuals:

Investor	Firm	Why they are relevant
Martin Casado	a16z	Leads infrastructure investing; deep networking and infrastructure background.
Joseph Ruscio	Heavybit	Developer tools, distributed systems, cloud infrastructure, APIs.
James Lindenbaum	Heavybit	Heroku co-founder; developer-first software and infrastructure investing.
Dana Oshiro	Heavybit	Developer-first companies, open source, infrastructure and GTM.
Brianne Kimmel	Worklife	Early investor in Webflow, WorkOS and Mux.
Sunil Dhaliwal	Amplify Partners	Technical infrastructure, data and developer-focused businesses.
Josh Kopelman	First Round Capital	Seed-stage investing and technical startup ecosystem.
Byron Deeter	Bessemer Venture Partners	Cloud software and enterprise infrastructure.

A few especially useful profiles to investigate:

Martin Casado — Investor profile.
Joseph Ruscio — distributed systems and developer infrastructure.
James Lindenbaum — particularly relevant for developer-first startups.
Brianne Kimmel — Worklife.

3. Additional firms worth including

These are less specialized than Heavybit or Amplify, but have meaningful histories in cloud and infrastructure investing.

Investor	Relevant portfolio examples	Why include
Accel	Atlassian, Slack, UiPath	Enterprise and developer software
Lightspeed Venture Partners	Nutanix, HashiCorp, Hasura	Cloud infrastructure and developer platforms
Sequoia Capital	Snowflake, MongoDB-related ecosystem, infrastructure software	Large-scale technical platforms
Bessemer Venture Partners	Twilio, PagerDuty, Shopify	Cloud software and enterprise infrastructure
First Round Capital	Notion, Webflow, Vanta	Early-stage software and technical founders
Felicis Ventures	Databricks, Harness, modern infrastructure companies	Data and developer infrastructure

These firms are worth investigating, but their stage appetite and partner-level interest should be confirmed for each fundraising process.

4. Individual angels and specialist investors

I would also build a separate list of operators and angel investors. They can be particularly useful for filling seed rounds and obtaining introductions to larger funds.

Investor	Relevant experience
Michael Grinich	WorkOS founder; invests in developer tools, APIs and cloud software
Philipp Moehring	Early investments in Prisma, n8n and other developer platforms
Lachy Groom	Early investor in WorkOS and other technology companies
Elad Gil	Early-stage investor in enterprise and infrastructure technology
Josh Buckley	Early-stage technology investor
Tom Preston-Werner	GitHub co-founder; developer ecosystem investor

Michael Grinich and Philipp Moehring are particularly interesting because of their explicitly developer-focused investment interests.

5. Where I would prioritize outreach

My recommended initial target order:

6. Research databases for expanding the list

These resources can help identify additional firms, investment partners, portfolio companies and historical deal activity.

VC Sheet – Developer Tool Funds — curated developer tools investors, including stage and check-size information.
FindFunding – Infrastructure & Developer Tools VCs — specialist infrastructure investors.
Fundraisly – Cloud Infrastructure Investors — broader database of funds and angel investors.
Devtool Angels — individual investors with developer tools experience.

7. A useful next step: build a targeted investor pipeline

The list becomes substantially more valuable when filtered according to the company raising capital.

For example, an observability startup should have a different investor target list from an open-source database company or a cloud security platform.

I can turn this research into a more comprehensive investor database, including:

Investor and firm name
Relevant investment partners
Portfolio companies and historical investments
Evidence of pre-seed, seed and Series A participation
Typical investment size, where publicly available
Geographic focus
Website and LinkedIn profiles
Potential fit and outreach priority

One important question: Are you researching investors for a particular startup, or are you building a general database of investors in developer tools and cloud infrastructure?

That distinction will help determine which investors deserve the highest priority.
