PrePost's proprietary index, combining capital-raising momentum, market-pricing confidence, and investor strength into one comparable score from 0 to 100. It lets you compare companies on those three measures; it is not a rating of the investment. How it works
Extremely fast re-rating: $3B (Sept 2025) to $9.3B (March 2026) in six months, driven by revenue growth from ~$2.8M to ~$150M annualized in under a year on Agent 3 and AI-coding demand. High execution/competition risk given how recent the underlying revenue growth is (Cursor, GitHub Copilot Workspace, Cognition, etc. all competing). Visa made an undisclosed-terms strategic investment around May 2026 tied to agentic-payments integration -- not a priced equity round, no new valuation disclosed. CEO Amjad Masad said in May 2026 he'd 'love for us to remain an independent company,' citing Replit has been gross-margin positive for over a year; no S-1 or IPO plan found. A circulating claim of a completed IPO at $14.5B could not be corroborated (no SEC EDGAR record) and is not used here.

Replit is a browser IDE in which each project runs in an isolated container on Google Cloud, with environments declared through Nix and hosting through Replit Deployments. Since 2024 it has released successive versions of Replit Agent, which writes, runs and deploys code from a natural-language prompt using third-party frontier models.

Patents. Five US filings under Replit Inc, two granted and three pending, cover the shared read-only Nix mount, technology related to Replit Agent, a multiplayer debugger, a mobile IDE and copy-on-write storage.
Replit, Inc. was founded in 2016 by Amjad Masad and Haya Odeh. The core is a browser IDE in which each project (a "repl") runs in an isolated container on Google Cloud, named as the infrastructure provider on April 25, 2023. Two decisions define the environment layer. The Universal Package Manager (July 19, 2018) detects and installs dependencies from spec files across languages. On May 24, 2021 Replit replaced its monolithic Docker image with Nix: the company said it prebuilt a roughly 1 TB Nix store of over 30,000 packages and mounts it read-only into every repl under /nix, so environments are declared in a replit.nix file rather than downloaded; by February 23, 2022 all new repls were Nix-based. That shared read-only mount is the subject of US 12,572,371 B2, granted March 10, 2026. Applications on a multiplayer debugger (2022), a mobile IDE (2022) and copy-on-write storage (2024) are pending.
Hosting was rebuilt as Replit Deployments on April 11, 2023 (Reserved VMs), with Autoscale and Static Deployments added September 5, 2023; the legacy Always On hosting was removed January 1, 2024. The company states Autoscale scales to zero and bills per compute unit, and that deployments run on isolated VMs; it publishes no independent uptime or scale data.
AI work began with Ghostwriter, announced September 7, 2022 and public October 31, 2022. Replit then trained two code-completion models: replit-code-v1-3b (May 2, 2023; per its model card, 2.7B parameters, 525B tokens, 20 languages, 256 A100 GPUs on MosaicML; weights CC BY-SA 4.0, code Apache-2.0) and replit-code-v1_5-3b (October 10, 2023; per its model card, 3.3B parameters, 1T tokens, 30 languages, 128 H100 GPUs; Apache-2.0). Replit Agent, which configures an environment, installs dependencies, writes and runs code and deploys from a natural-language prompt, launched in early September 2024 in early access; the related patent US 12,591,416 B2 (priority February 22, 2023) was granted March 31, 2026. Agent v2 entered early access February 25, 2025 alongside Anthropic's Claude 3.7 Sonnet; Agent 3 (September 10, 2025) added browser-based self-testing, and the company claims runs of up to 200 minutes at a median testing cost of $0.20 per session; Agent 4 (March 11, 2026) added a design canvas and parallel agents, which the company claims is 10x faster than Agent 3. A Security Agent using Semgrep and HoundDog.ai shipped April 21, 2026, and a "Free Mode" on OpenAI's GPT-5.6 Luna on August 18, 2026. The agents run on third-party frontier models; Replit's own trained models are the 2023 completion models.
Formal IP consists of five US filings under Replit Inc (two granted, three pending) plus the CC BY-SA 4.0 and Apache-2.0 model releases, whose ReplitLM repository is now archived. Replit has made one acquisition: OpenInt, an integration platform that Replit said supported over 160 connectors, announced September 30, 2025 for undisclosed terms; it became the basis of Replit Connectors and its cloud service was wound down December 31, 2025.

These are on the public record as giving exposure to Replit. Buying one means owning a stake in the vehicle, not in Replit, and the vehicle takes fees along the way.

On the public record means the vehicle exists in a regulatory filing or a public product document. It does not mean PrePost has vetted it, or checked that it suits you. What each of these really is, and what comes off your return, is in the instruments primer.
Ordered by how much of the vehicle this company is, never by payment. How we stay independent.
| Status | S-1 Not Filed |

| Notes | A circulating claim of a completed IPO at $14.5B is unverifiable and contradicted by CEO Amjad Masad's stated preference to stay independent ('I would love for us to remain an independent company'). |
