Comparison
Vs boutique agency, vs Big-N consultancy.
Most enterprise buyers compare a boutique technology consultancy against a Big-N firm. LoneSock fits neither template: an owner-operator consultancy with its own platform, own data center, and direct delivery from the same principal engineer across every engagement.

|---|---|---|---|

Frequently asked
About the company, in plain language.
What does LoneSock do?
LoneSock is the custom software consultancy arm of KaritKarma Limited. We build enterprise-grade systems for clients in banking, telecom, media, entertainment, and government, billed at $40/hour with source code delivery on every engagement.
Why is the rate $40/hr?
Our principal engineer and core team are based in Bangladesh. The cost structure is local, but the engineering output is built to the same standards as the KaritKarma platform that powers banks and ISPs. The rate is not a discount, it is the actual cost of senior engineering delivered from Dhaka.
How is LoneSock different from KaritKarma?
KaritKarma is the product company. It owns and operates a 22-product portfolio including Wenme, Darwan, BizRP, BitsPath, and others. LoneSock is the services arm of the same parent. When you hire LoneSock you draw on the KaritKarma platform as integrated components, not as a vendor relationship.
Who is the principal engineer?
Lutfar Rahman, also known as Nirjhar, is CEO of both KaritKarma Limited and LoneSock Consultancy. He has been writing production code since 2000 and is the architect behind the KaritKarma platform.
Where are LoneSock clients located?
Active engagements in Bangladesh, the United Kingdom, the United Arab Emirates, and the United States. The team works async-friendly with timezone overlap when client cadence requires it.
Do you take equity or revenue-share deals?
Occasionally. For projects with clear product-market fit and aligned founders, LoneSock can blend cash with equity or revenue share. The default engagement is cash at $40/hr with source code delivery.
