Emergent review

Emergent is an AI app builder. You describe an app in chat, and its agents write the code, test it and host it, for web apps and for native iOS and Android apps ^9,14. Co-founders Mukund and Madhav Jha started the company; it says it is headquartered in San Francisco, but 70 of its 75 employees worked in Bengaluru at the time of its Series B ²⁷.

Emergent raised a $70 million Series B in January 2026, led by SoftBank Vision Fund 2 and Khosla Ventures at a $300 million valuation ²⁷. In July 2026 it raised $130 million in a Series C led by Creaegis at a $1.5 billion valuation, taking total funding to about $230 million ²⁸.

Before the first message you pick an agent: E-1 builds step by step, E-2 checks that the pieces fit together, and E-3 runs E-1 under its own loop for large goals ¹⁵. The default stack is React, FastAPI and MongoDB, with Next.js and Expo/React Native templates ¹⁴. The agent works in a preview sandbox that sleeps after 30 minutes, saves a checkpoint after every turn, and lets you roll back or fork the app ^7,16. On request it runs tests, fixes failures and re-runs them ¹⁰.

Publish creates a separate production app with its own secrets, at an emergent.host address or on your own domain ^7,8. Re-publishing is free, and production can roll back to one of its last 3 images ⁷. For mobile, Emergent runs the Expo build in its cloud, uploads iOS builds to TestFlight and hands you an Android bundle for the Play Console ⁹. You can add your own MCP servers so the agent can read data and call tools while it builds ¹¹.

Standard costs $20 a month billed monthly, or $17 billed annually, and includes 100 credits; Pro costs $200 a month with 750 credits ¹. Credits pay for everything: prompts, tests, integrations, LLM calls from your app and hosting ^4,5. A single prompt can use a handful of credits or hundreds ⁴. Each live app also pays a fixed monthly tier fee, from 50 credits on Starter, which Emergent says is not suitable for production load, to 1,100 on Elite ⁶. One app on the Launch tier (125 credits) already exceeds Standard's monthly allowance. Top-ups start at $50 for 250 credits, never expire and are non-refundable, while unused plan credits expire each month ⁵. When the balance hits zero, builds pause, and a negative balance can take a live app offline ⁵. Refunds are prorated on unused subscription credits only ²⁵. Budget for Standard plus top-ups, or Pro for daily building.

Emergent says it is certified to ISO 27001 and holds a SOC 2 Type I report; its trust centre lists ISO 27001:2022, SOC 2 and GDPR ^19,20. There is no SOC 2 Type II report and no HIPAA BAA ^19,23. Emergent does not train models on customer personal data and bars its AI sub-processors from doing so, but operational service data may train its models, with no opt-out ²¹. Data is processed in the US, the EU and India, and you can choose a live app's hosting region ²². Secrets are encrypted at rest, and the agent never sees production secret values ²⁴. No built-in security scan of the apps it builds is documented; Emergent gives you a pre-launch safety checklist instead ²⁴.

Independent ratings are thin and mostly negative. Trustpilot shows 2.8 out of 5 from 639 reviews, 48% of them one-star; reviewers cite fast-draining credits, unclear costs, refused refunds and slow support, while others praise how fast it turns an idea into a prototype ²⁹. G2 shows 4.3 from 8 reviews ³⁰. Emergent publishes case studies such as Autoverse Mobility, a Bangalore parts distributor that built five operations apps on the platform ²⁶. Its user and revenue figures are company statements ^2,27,28.
