Accel

Choose the right track

• Building an AI company at pre-seed: Accel Atoms AI, which looks at founders working anywhere in the AI stack.
• Building something new outside AI, or applying as a solo founder: Accel Atoms X, which is sector-agnostic and accepts solo founders.
• Already past pre-seed with revenue: Atoms is aimed at pre-product or pre-revenue companies, so it is probably the wrong door.

How applications work

• Applications go through the form on the Atoms website. Referred founders use the same form.
• There is no email inbox for pitches, so do not cold-email the team in place of applying.
• You do not need to be incorporated to apply, but you will need to be before an investment closes.
• The AI cohort had a fixed deadline in 2026. If you miss a cohort, later applications are considered for the next one.
• The application page was showing an upgrade notice instead of a form when we last checked, so confirm that the form is live before you draft anything.

How selection works

Accel says it looks at three things: the team, the idea and the market. The investment decision is made by Accel's own investment team, and Accel invests as equity or a convertible note. For Atoms X, Prosus Ventures matches Accel's investment.

What reviewers look for

• A strong founding team. Team comes first in Accel's list of criteria.
• A clear idea and market. You do not need a product or revenue, and an MVP is not required.
• Full-time commitment. Atoms X expects founders to build the company full-time.
• Fit with the track. AI founders should show where they sit in the AI stack. Atoms X founders should explain why their approach is a breakthrough in product, technology or business model.

Accel is a venture capital firm with offices in the Bay Area, Bangalore and London. For early founders in India its one standing route in is Accel Atoms, a pre-seed cohort programme run by the Accel AI investment team and based out of the Bangalore office in Koramangala.

Atoms is not a separate accelerator body. It is a product of Accel's own investment team, which means the people running a cohort are the same people who decide whether Accel invests. Accel says it has backed more than 40 early-stage startups through Atoms since it launched the programme in 2021.

How Accel Atoms works

Atoms runs as small cohorts of early-stage teams, typically for three months. Accel invests in selected startups as equity or a convertible note, depending on the stage, traction and fit with the cohort, so this is an investment programme, not a grant. Selected founders also get access to Accel's network of founders, investors and industry experts, and to a set of perks from network partners.

There are two live tracks. Accel Atoms AI is for founders building across the AI stack. Accel Atoms X, announced in July 2025, is a sector-agnostic track for mission-centric founders building what Accel calls LeapTech, meaning a breakthrough product, technology or business model. Prosus Ventures matches Accel's investment in each Atoms X startup.

An earlier edition, Atoms 4.0, was announced in September 2024 with two thematic cohorts, AI and Bharat. It has been superseded by the AI and X tracks and is closed.

The 2026 AI cohort

The 2026 AI cohort was run with Google's AI Futures Fund, which Accel describes as Google's first programme of its kind anywhere. The two funds co-invested in each selected startup, and the programme included compute credits. The application deadline was 26 January 2026. Five companies were chosen from a global pool of thousands of applicants, and the cohort began in March 2026 at Google Ananta in Bengaluru. An earlier announcement had given February as the start.

Who can apply

Atoms is open to founders based in India and to Indian-origin founders based anywhere in the world. The programme is most relevant to companies that are pre-product or pre-revenue, and a working MVP is not required. The company does not need to be incorporated to apply, but it must be incorporated before an investment closes. Accel supports companies that have raised only a limited amount of outside capital so far and states a ceiling on this.

For Atoms X, solo founders can apply and co-founders can apply together. Founders are expected to build the company full-time, ideally from idea or prototype stage. Accel says it looks at the team, the idea and the market.

How to apply

Applications go through the form on the Atoms website. Founders who are referred to Atoms fill in the same form, and there is no separate inbox for cold emails. Accel's July 2025 announcement says applications are open all year, and the programme site says later applicants are considered for future AI cohorts. When we checked on 7 October 2026, the application page showed a notice that the application is being upgraded instead of a form, so check the Atoms website before you plan around a date.

Scale

All figures here are Accel's own. Accel says more than 40 early-stage startups have been backed through Atoms since 2021, and that over 30 percent of them have gone on to raise follow-on rounds. The first Atoms X cohort of six companies was announced on 25 March 2026, chosen from over 2000 applications. Its pages give different cohort sizes for Atoms X, with one stating a smaller number than the six companies actually selected.

Who runs it

Atoms is run by the Accel AI investment team. In January 2025 Accel announced its eighth early-stage fund for India, and said it began working with founders in India sixteen years earlier. Accel's contact page lists Palo Alto first, then the Bangalore office in Koramangala, and a London office.

Locations

The Atoms team works from Accel's Bangalore office in Koramangala, 6th Block. Indian-origin founders outside India can apply to Atoms as well. The 2026 AI cohort started at Google Ananta in Bengaluru.
